Val's LASIK Story

Why this page exists

While I was researching LASIK, I found first person accounts of LASIK patients more helpful than most surgeon's web sites. Then, a few days before I got the surgery, a friend of mine announced the birth of her baby in an email with a link to a web page about it, complete with pictures. I now live in the future, where we announce major events by writing a web page (and not so major events... I put party invitations on the web, too). And several friends and family asked me to let them know how my LASIK went, so rather than tell them all the details individually, I decided to write it all down once.

Each entry starts with the date the events occurred, although I wrote most of it shortly after my surgery in July 2003. I'm including excruciating detail because there were a lot of surprising things in my LASIK surgery, and I'd like to help other people have a better idea of what to expect. I have updated it periodically for about two years, and probably won't update it again unless something terrifically interesting happens.

Sometime in 2000

I first seriously started researching LASIK back in 2000, when my optometrist recommended it to me. I'm very nearsighted and very very nearsighted in my right and left eyes, respectively. Specifically, my prescription is:

Right eye: -5.5 sphere, +2 cylinder
Left eye: -10.0 sphere, +2 cylinder

In non-optometrist speak, this means that my right eye could see about two feet away before things get blurry, and my left could see about 6 inches away, plus the image is really distorted (astigmatism is the cylinder measurement). The reason my optometrist recommended LASIK is because the more myopia has to be corrected, the smaller the image appears on your retina. When my vision is fully corrected, I have a significantly smaller image in my left eye than my right eye. Most brains have difficulty reconciling images that have been corrected by lenses that differ by 2 or more diopters (much less 5 diopters) and attempting to do so may give you eye strain headaches. Whenever I go to an optometrist, they marvel at the difference between my eyes and that I can function with the difference in image size. Sample quotes: "Wow, it's amazing you can see," "My husband got LASIK in one eye first and couldn't take the 2 diopters difference," and my favorite, "Wow, your eyes are WEIRD."

In 2000, I was 22 and had been working for a little over a year as a programmer, so I could afford LASIK. I spent a few weeks researching LASIK on the web and eventually decided that the technology wasn't good enough for me yet. To explain why, you have to know a little bit about LASIK first.

In LASIK, the surgeon cuts a circular flap in the epithelium (outer layer) of the cornea, leaving one section of the circle uncut so it stays connected to the eye. Then the flap is lifted and the cornea underneath is reshaped by burning away parts of it with an ultraviolet laser. The flap is put back down over the cornea (after rinsing away debris), where it almost immediately adheres back to the cornea. This keeps most of the raw damaged area where it won't be irritated by your eyelid or random junk getting in your eye. In PRK, they just burn away the surface of the eye, and the epithelium takes a long time (several weeks) to grow back, during which time the eye is painful and blurry. It's interesting to note that the cornea is the fastest healing tissue in the body. If you've ever had a corneal abrasion (i.e., eyeball scratch), you'll notice that it heals up in about a day or so. Try that with a scratch in your skin!

I decided not to get LASIK in 2000 for several reasons. First, the diameter of the flap they could cut and the area they could reshape were too small, in my opinion, compared to the size of most people's pupils. I don't recall the exact numbers, but I think the flap was something like 7 mm in diameter, which is the average size of a dark-adapted human pupil, and the treatment area (the area they actually reshape with the laser) was smaller. This is bad because it increases the risk of night glares and halos, the scariest side-effect of LASIK. Next, the laser they used to ablate the cornea didn't have a way to track eye movement. The surgeon would watch your eye, and if it moved, stop the laser, hopefully quickly. This seemed like something that should be handled automatically. The treatment couldn't be customized beyond the two-parameter sphere/cylinder measurements. This also seemed to me like something that could easily be improved. In addition, my eyesight still hadn't stabilized, and as I discovered later, most surgeons won't do LASIK until you are at least 25. So, no LASIK for me in 2000. Instead, I spent $400 on glasses and $600 on contacts.

Early 2003

I started investigating LASIK again in early 2003. I needed a new pair of glasses, for once not because my prescription had changed, but because my frames were wearing out (one part was held together with the metal from a twist tie, which happened to be color-coordinated with the frames so I didn't feel ostentatiously geeky). And I was really really unhappy with my contacts. They had to be custom-made, they were very thick and uncomfortable, and they wouldn't stay in the right orientation to correct my astigmatism. At any point in time, one of them might rotate and turn my vision into a collection of horizontal smears. Driving at night with contacts was nearly suicidal, due to all the glares and artifacts that appeared around every light each time my contacts rotated a few degrees. As a result, I wore my contacts approximately once a month. My glasses were better, but stars hadn't looked like stars for several years - they more closely resembled hand-drawn five-pointed stars than they did points of light. I had no desire to spend another $1000 for badly fitting contacts and glasses that only partially corrected my vision. So I started looking into LASIK again.

In the intervening 3 years, all of my concerns had been addressed! Flaps were now larger, new eye-tracking lasers were approved by the FDA (they'd been in use in Canada for years), and WaveFront Sciences had produced a way to measure high-order aberrations of the eye (stuff other than sphere and cylinder) and create a custom treatment for them. Plus, my prescription hadn't changed in at least 2 years. I decided to wait a few more months before actually getting it done (okay, I procrastinated - I hate making doctor's appointments, it's just an annoyance and a distraction from a day full of programming).

Early July, 2003

I finally got serious about LASIK when I planned a trip to Hawaii with my mother and sister. My little sister is a big-time scuba diver and convinced me to go scuba diving with her in Hawaii. At one point, I realized that it was going to be pain to see while scuba diving. Glasses aren't an option. You can rent goggles with correcting lenses - if you don't have freaky eyes like me. Contact lenses might fall out if your mask floods, and my contact lenses frequently have to be adjusted by closing my eye and pushing it around with a finger, something I can't do in a mask. Nothing seemed to make sense - except LASIK, if I could get it done in time. A little googling told me that you could scuba dive about two weeks after LASIK. It was July 1st, and I was leaving on August 25th... better get going!

I used Google to find Peninsula Laser Eye Medical Group. They had the new eye-tracking laser, WaveFront, the big flap, and they were only a few miles away, in Mountain View. The surgeons seemed wildly overqualified and had done literally thousands of surgeries. They were also the only surgeons in the area certified by the Council for Refractive Surgery Quality Assurance, another random site I found on the web. I scheduled an evaluation on July 7th.

July 7, 2003

At the office, I was greeted by Barbara, who was very friendly and reassuring. She ran me through some tests, including the WaveFront measurement. Dr. Beers, my surgeon, did a few more tests, double-checking the WaveFront measurements, measuring the thickness of my corneas, and measuring pupil size. The cornea test was cool! He gave me some numbing eye drops, and then used a machine that looked very much like some sort of multi-meter or a very small oscilloscope. The sensor was attached by a long cord, and it looked almost exactly like someone cut the cord of a pair of headphones and attached it to the machine. He held the end (the part that plugs into the CD player) very near my eye (so I thought) and I saw a ring of dark circles ripple outwards from the tip. Barbara read off several numbers and then we were done. I asked him what he did, because the visual effects were so cool, and he told me that the sensor actually touches the cornea - I just hadn't noticed because of the numbing drops. The rings were the effect of pressure. When touching the cornea, the sensor uses ultrasound to measure the cornea's thickness.

I was a little suspicious of the pupil width test. I'd read a web page about all the ways pupil width can be mismeasured, and it seemed to me that the room was awfully bright to find out how big my pupil would be during night-time driving conditions. He told me I have 6mm wide pupils, which is good because it's smaller than the treatment area, but is also below average (7mm) and somewhat unlikely. LASIK doctors have strong incentive to measure pupils as small as possible, since that makes LASIK a better option. But I double-checked as well as I could, looking into the rear view mirror while driving at night (quickly, so my pupils wouldn't have time to shrink to focus up close), and then estimated how big my pupils were by visually memorizing the ratio of iris to pupil and later measuring the width of my iris. This is totally inaccurate, but it backed up the 6mm measurement. Note that when your eyes are dilated chemically, the pupils are larger than during night driving (mine are around 7-8mm fully dilated).

My WaveFront measurements showed that I actually had very regular astigmatism (meaning the distortion is smooth and doesn't vary much), with only 1% "high-order" astigmatism in my left eye and 5% in my right. 10% is considered "a lot." It turns out WaveFront isn't FDA approved for the level of myopia in my left eye (which didn't really need it anyway), but my right eye was a candidate. It didn't really need it that badly, but I wanted to have the best chance at perfect vision.

Finally, Barbara told me the price tag: $1750 for the left eye, $2250 for the right. Yow! But that includes all the medication, follow-up visits, and a retouch if my eyes aren't completely corrected. Everything I read indicated that looking for the cheapest price was the last thing I wanted to do, they seemed really overqualified, and I hate shopping, so I decided to go for it. I was still prepared to call up and cancel the appointment if I changed my mind, but I decided to schedule the treatment. I initially chose July 18th, but then realized I'd be in Ottawa for Ottawa Linux Symposium for more than a week shortly after the surgery. Usually, surgeons schedule follow-up visits one day, one week, one month, and one year later, at a minimum, and I'd miss the one week follow-up. Dr. Beers (who does his own follow-up appointments - some surgeons pawn you off on a regular optometrist) wasn't happy with missing the one week follow-up, and mentioned he might have an opening on... Thursday. Gulp. I went for it.

July 8th, 2003

On Tuesday, I thought of several more questions I wanted answered, all related to the chance of glare and halos: what size was the flap, how big was the treatment zone, and would I have a "blend zone"? The blend zone is a smooth transition area between the treatment area and the untreated cornea. The theory is that it reduces sharp transitions that might cause glares. Dr. Beers called me back within a few hours and answered all my questions: flap size was 9mm, treatment zone was about 6mm, blend zone is built-in to WaveFront, and I'd be getting a blend zone on the left eye too. That covered the last of my concerns, so I was ready to go on Thursday!

July 10th, 2003

Thursday morning, I drove over to Richard's house, who was going to drive me to the surgeon and back (only a mile or so from his house), and take care of me after the treatment. I took the 5mg Valium tablet about two hours before the surgery. I didn't feel noticably different when we arrived at the doctor's office and decided to get the second tablet of Valium. Another patient was waiting for treatment, and she sounded waaaaay more relaxed than I did, so I felt justified in asking for more sedative.

Richard sat with me while they did some last-minute checks and went over my post-operative treatment (summary: lots of eye drops). Barbara gave me the second Valium and helpfully told me that it would work faster if I chewed it up, but it would taste bad. I chewed. It tasted bad. I asked Dr. Beers, "Does the thing to hold your eyelids open look like the one in 'A Clockwork Orange?'" He laughed and said, "Yes. We get that one a lot." I figured that, but the only way I would know is if I asked. Barbara put one of those surgical caps on me (I was wondering what they'd do about my hair) and tucked gauze squares under the cap near my ears, "To catch the eye drops," she said. "Sometimes when we're done those squares are dripping wet." As we were wrapping up, I noticed that no one had said my name, so, feeling paranoid, I said, "I have one more question. What's my name?"

The surgeon stared at me a moment, looked at his chart, and said, "Bob?" Richard and I giggled. "No, you're Valerie Henson." I'm glad he had a sense of humor about it. We joked about operating on the wrong person (or wrong eye) and then we were ready to start. Richard left to go rent some movies for me to watch (ironically) while I was recuperating.

Begin scary unpleasant time. Barbara led me into the treatment room, giving me a running monologue about what to expect. The room was kind of cold, so she offered me a blanket, which I gladly took. I sat down on a chair resembling a dentist's chair, which she lowered down flat. She strapped me into the head brace, which was very comfortable and reassuring. I wish I had a pillow like that head brace. She asked me not to cross my legs, since that makes your body more unstable. They gave me the numbing eye drops and started calibrating and testing the equipment, giving me a running monologue about what each sound was and when I would hear it. They turned off the room lights and swung the laser over my head. The only lighting at this point was the little blinky red light I'm supposed to focus on, and some surprisingly bright lights illuminating my eyes obliquely.

This is when I discovered I was pretty nervous - my heart rate was about 90 and my stomach was hurting. Maybe I would have been more nervous without the Valium, but I couldn't tell the difference about then. At this point, I noticed that Barbara had one hand over mine and the other was rubbing my arm. I think that was her entire role during the treatment, and I was infinitely grateful for it.

They taped my right eye shut and put the the eyelid spreader on my left eye and put in a bunch of drops, which were mostly suctioned away somewhere between my eye and my ear. The eyelid spreader was surprising comfortable, and I felt no need to blink. The surgeon did mysterious things with odd looking instruments very briefly. Then it was microkeratome time - time to cut the flap. A large black instrument appeared over my eye and bore down. The red light faded out. (The whole time the surgeon was giving me a running monologue of what he was about to do - very nice. He asked me if the light was going out, which was somehow more reassuring than telling me that it would go out.) I heard a noise surprisingly like a circular saw for a few second, then the pressure went away and I could see the light again. I saw the flap being lifted away (the hinge was on the side towards my nose, to my surprise - it's always at the top in the animations) and then the red blinky light was very blurry.

Now the really unpleasant part - the laser. This is where I actually had to do something other than lie still - I had to keep focused on the light while they zapped my cornea. This is surprisingly hard. I had the idea that if I just didn't move my eye, the light would stay put. But instead, it kept drifting away, and I had to move my eye to get it back. This wasn't very pleasant - you're supposed to keep the light centered, but you also aren't supposed to move your eye. These are contradictory requirements. Fortunately, I was being treated with the eye-tracking laser, so I eventually got used to moving my eye tiny bits to keep the light centered.

The laser operates in pulses, with a snapping sound accompanying each pulse (which they'd already habituated me to earlier). To my immense surprise, I could see faint purple flashes, which briefly drowned out the dim red blinky light. Every twenty seconds or so, they stopped and I would see a white brush-looking thing sweep over my cornea. I assume this was removing debris. Then more eyedrops, then more zapping. The whole time they kept praising me and telling me I was doing good. This was very reassuring and I appreciated it a lot, since I felt like I couldn't keep the darn light centered and was doing a terrible job.

Before the treatment, I'd theorized that the vaporized cornea would smell a lot like burning hair. I was pleased to find that I was correct - it wasn't a very strong smell, and wasn't quite as bad, but it definitely resembled burning hair.

Finally, the laser was done. My left eye took around 60 seconds of laser treatment, with two breaks. More white brushes went by, with a lot of eye drops. Eventually, the flap came back down, followed by more brushing and eye drops. They told me to close my eye and taped it shut, ready for the next eye.

The right eye was just about the same, except that it was a shorter treatment time (around 30 seconds), and I think the numbing drops had started to wear off because the microkeratome hurt a little bit. This time, when they put the flap back, I could see the red blinky light very clearly. Done!

They turned the lights back on and my first sight of the new world was very blurry, but still much better than my uncorrected sight. The blurriness was more like the kind you get after wearing contacts too long, not like nearsightedness. We went into an exam room and tested my eyes, which were somewhere around 20/80 or so at that point. My left eye was worse. While waiting for Richard to come pick me up, my eyes started hurting. Barbara told me that the younger you are, the more nerve endings you have in your cornea. Mine were complaining.

I kept my eyes shut on the drive to Richard's house, hoping that the pain wouldn't get worse. It felt very much like a big gout of soap in each eye, except that it never went away and kept getting worse. Foolishly, I decided to wait until I got to the house to take the Vicodin they gave me. This was a bad idea. I heartily recommend to anyone else going through this to take the Vicodin the instant they allow you to. At Richard's house, I finally took the Vicodin and got ready for bed. Richard taped on my eye shields for me and gave me a pillow case to drape over my eyes and keep the light out. I asked Richard to stay and talk with me until the Vicodin kicked in, which turned out to be an hour.

My eyes hurt so badly that I could only open my eyes a tiny slit for a fraction of a second. I did this in order to let the tears out, which otherwise built up pressure under my eyelids. Even the muscles in my brow were involuntarily furrowed. I didn't realize how little control I had over the muscles around my eyes when they were in pain.

I was really surprised by the pain. No one else had mentioned anything this bad. I think that this is for two reasons: I don't know anyone else who got LASIK as young as I did (age 25), and correcting my vision required removing a lot more corneal tissue than usual. In any case, don't let this happen to you: Take the Vicodin right away!

Five hours of dozing and petting Richard's cats later, I could open my eyes and blink without pain. Even through the eye shields, I could see that the blurriness was better. I took another Vicodin, just in case, although I didn't feel any pain. I spent a few hours writing this web page, watching movies, and putting in eye drops. After dark, I went outside and looked at the stars, the streetlights, and the headlights of passing cars. The stars were points of light, according to my right eye, but still blurry with my left. The glare around streetlights and headlamps was a little brighter and more defined than before the surgery, but it was by no means crippling. I went back to sleep, eye shields taped firmly in place.

July 11th, 2003

The next morning, I got in the shower and had a mild shock. Something was different. What? It took me a second to figure it out. I've taken a shower with my contacts in maybe 10 times in my life, and usually water gets in them right away and blurs my vision. The experience of stepping into the shower and being able to see the tiles was utterly foreign.

I drove myself to my check-up appointment. I had 20/20 vision in my right eye and 20/25 in my left, less than 24 hours after the surgery. This is a little misleading, because the swelling in my eyes caused a lot of double images, but I wasn't concerned about that. I spent the rest of the day working from home, with frequent breaks for naps (or at least lying down with my eyes closed). Even so, my eyes were definitely scratchy by the end of the day, but not painful. I recommend trying to spend the second day after the surgery sleeping (or lying down with eyes closed) - the feeling of a corneal abrasion is not particularly pleasant and the best thing you can do is keep your eyes closed.

At this point, about 30 hours post-op, I'm extremely happy with my new eyesight. Due to post-op swelling and unfinished healing, images (especially high-contrast, low light images) are still blurry. Black text on a white background on my computer screen is especially blurry, but not so much that I couldn't write this web page. The blurriness is already better since yesterday. I have some degree of night halos, but they aren't bad, and should improve. Even if this is as good as it gets, it's still infinitely better than my vision was before.

July 15th, 2003

I went in for my 5 day follow-up appointment today. My vision is now 20/15 right eye, 20/20 left eye. The blurriness is noticably better, but still there. Night-time halos are noticably dimmer and smaller now. I discovered another interesting glare phenomenon: the sun's reflection off of car windshields during the daytime is more spread out and larger, though not by much. This glare has also improved noticably. Dr. Beers estimated that it would take my eyes around a month for my vision to stop changing, due to the swelling and continued healing. He told me that my corneas look nice and clear, and I'm not having any trouble with wrinkles in the flap or anything else. My left eye feels a little scratchy when I wake up in the morning, but it's not painful. I don't have to use the steroid or antibiotic drops any more (I only needed them 4 times a day for 5 days), but I do need to keep using eye drops for another month or so in order to speed up the healing process. I have bumped my eyes (while they were closed) a few times, and they are tender enough to remind me not to do that, but not much more than that. I'm planning to go out and buy some more button-up shirts - one of those accidental bumps was while pulling a t-shirt over my head. Ouch!

At this point, the hardest part is being patient and waiting for the healing process to finish. My vision is better than it has been since I was at least 8 years old (and probably even before that), and yet I'm having a hard time waiting a month for the swelling to go down. Sheesh!

Another annoying surprise: Putting in eye drops makes your vision blurrier for a few minutes, even after you think you've blinked all the excess away. I think this is a property of the healing eye - at least I don't remember it working this way before my surgery. Also, I haven't gotten any better at putting in eye drops. You'd think it would be a relatively simple skill to acquire...

I've almost stopped trying to push up or take off my glasses. Almost. I keep thinking I'm going to poke myself in the eye with my own finger. Wouldn't that be a riot - the One Stooge!

July 31st, 2003

My left eye is slowly going more and more astigmatic. It's only really noticable with the computer screen or at night. When I focus on a light, the smear of light from the astigmatism shrinks and disappears -- my pupil is contracting when I focus on a light. I don't really need eye drops any more, although I had a bad spell last week when I went out drinking until 4am and forgot to take my eye drops with me. Remember: always have your eye drops in your pocket! The right eye is still fine, though.

October 8th, 2003

It's been about 3 months since my surgery. I have noticable astigmatism in both my left and right eyes in dark conditions, but I no longer notice it even when driving unless I think about it. In anything close to daylight conditions, my right eye is perfect and my left has a tiny bit of astigmatism. The glare around sun reflections on windshields is back to normal. I no longer have problems with dry eyes or waking up with scratchy eyes. All the tenderness in my corneas is gone. My eyes appear to be completely healed, three months post-op, although I'm certain my surgeon would disagree. I'm really, really happy with my LASIK.

I realized that I've started doing things that I wasn't willing to do with glasses or contacts. Since I got LASIK, I learned how to scuba dive and surf. I could have done them with contacts, but I would have spent the whole time worrying they would pop out, rendering me blind and poorer by a few hundred dollars (even "disposables" were insanely expensive for me), and blinking to get them oriented in the right way for my astigmatism. I go swimming a lot more often now, I roller blade regularly, and I started taking yoga. Since my contacts were so uncomfortable that I almost never wore them, to do these things I would have had to choose between being blind, taking the time to switch to contacts, or pushing my glasses up on my sweaty nose.

Standing there on the beach after my first attempt to surf, I realized how much LASIK gave me simply by making it possible to try new things without a second thought about how I would see. All the time I used to spend worrying about my glasses or contacts I now spend on having adventures and trying new things.

Inspired by my success, my friend Bill got LASIK a few weeks ago. I was jealous to discover that the equipment his surgeon used was even more advanced than mine. Apparently, there are a number of advantages to creating the flap using the new femtosecond lasers instead of a microkeratome. Among other things, the pressure on your eyeball during the cutting of the flap is much lower, and the consequences of a mistake are less severe. He also told me that the reason your eyes are so dry after LASIK is because the nerves leading from the surface of your cornea are cut, and so your nervous system doesn't know that your cornea is getting dry and doesn't blink your eyes automatically. The nerves usually grow back (mine did, evidently), but when they don't, you get permanent dry eye, which you can apparently improve using little plugs in the ducts that drain the eye. Ugh. I'm glad my eyes are back to normal.

A few people have asked me who Bill's surgeon was. He's Dr. Steven Turner of the Turner Eye Institute, located in the Bay area. If I had to do it over again, I'd probably go there.

March 8th, 2004

It's been about 8 months since I got LASIK, and my eyes are still changing a little bit. I ordered computer glasses a couple of months ago because it was getting hard to read my (itty bitty) font after working for more than 6 hours or so - astigmatism. But I stopped using them about a month ago because the astigmatism got better. I can now read my screen clearly with either eye even after 9 hours at the computer. At the same time, my night driving vision got bad enough that I thought I would need glasses for driving at night too, but it has also improved over the last month. Both eyes are around 0.5 diopters off from perfect, either farsighted or nearsighted, and both have minor astigmatism. Eyesight during daylight continues to be perfect. Driving at night, I have smears from astigmatism, but I can still read signs from far away and oncoming headlights, as always, actually improve my night vision by shrinking my pupils. My eyes are dry when I wake up in the middle of the night, so I keep eye drops by my bed, but I don't have trouble with dryness at any other time.

Continuing my adventures in eyeball-appliance free world, I rejoined the SCA, a medieval recreation group, and got back into our form of medieval combat recreation (which involves hitting each other with sticks). Here's a picture of me taking a break from hitting each other with sticks. Going to an SCA event used to involve lots of contact-related annoyance because we usually camp out - ever put in a contact bathed in 40 degree Fahrenheit solution? I also started playing hurley, an ancient Irish form of field hockey.

I only now discovered, at age 25, that I love playing sports. Since I got LASIK, I learned how to scuba dive, surf, and play hurley; I now swim, roller blade, and run regularly; and I practice my wacky medieval martial art two or three times a week. I don't have expensive dangerous objects that I have to keep near my eyes at all times and take care of and worry about losing. I'm extremely happy with my LASIK.

September 9th, 2005

It's been a little over two years since I had my LASIK. My eyeballs don't feel dry ever any more, not even at night or when I've been drinking. The astigmatism is the same - a little at night or in high contrast situations like a computer screen. I just found my computer glasses today after not using them for several months. The last time I needed them, I was pulling 90-hour weeks on a project and I think anyone's eyes would have given out. Basically, I need my glasses if the muscles around my eyeballs get too tired to correct the astigmatism. Glare is unnoticeable. I'd have to say my surgery was 99% successful - the slight astigmatism is the only thing I have to complain about, and it doesn't impair my night driving, which was my biggest fear. Most importantly, all my friends are jealous of my LASIK. Ha!

Update: January 8th, 2008

I went to the the most thorough optometrist I've ever met, Dr. Tuyen Tran, last week. After examining my eyes for nearly an hour, she announced that my LASIK was very well done with almost no scarring at all. I've got 20/20 vision in my right eye but have dropped to 20/30 in the left, with some astigmatism (which is still thrillingly great). She also explained to me why I will always need computer glasses; the natural alignment of my eyes results in my eyeball squishing in one direction when I'm focusing up close, and then the other eyeball muscles have to squish in the opposite direction to compensate. Eventually the muscles get tired and can't squish my eyeball any more and things get fuzzy. My (very fashionable and deductible!) new computer glasses will have a prism effect among other things to reduce the eyeball squishing necessary. I also got some night driving glasses since the expanded pupil in combination with the astigmatism in my left eye is creating some glare which interferes with my vision (the glare is not due to any part of LASIK). I still feel safe driving at night, but it will be nice to have nearly perfect vision.
