I got iLasiked recently.
I've thought about it on a number of occasions but haven't pulled the trigger until now.
One only has one pair of eyes per lifetime, and online accounts of unsatisfactory outcomes and medical complications on
http://www.lasermyeye.org/forums/ and
http://www.lasikcomplications.com/ are enough to give anyone cold feet.
On the other hand, as someone who has been quite myopic (with significant astigmatism) since childhood, the idea of waking up and being able to see a clock without first fumbling blindly for glasses is quite an attractive and novel concept.
Moreover, it'd be nice to ditch at a stroke all the special eyewear for sports that I've accumulated over the years, e.g. prescription googles for swimming, and a prescription facemask for snorkeling and scuba diving. Contact lenses for running and table tennis to avoid sweat causing glasses to slip or become streaked and unclear. Two pairs of ski googles: one to fit over glasses, another for use with contacts. Why not ditch the glasses and just use contacts? I have soft toric lenses but for use on computers or reading, my eyes get easily tired. So I use glasses for those tasks. Also, I can't safely wear contacts during cycling even with eye protection: 50+ mph descents can tear at and dry out one's eyes, putting the lenses at risk of falling out. Moreover, for ultra-distance events, a 24 to 60 hour bike ride with contacts can be quite a trial.
I had an initial 2 hour consultation at an English-speaking clinic in Tokyo where they determined without sales pressure that I was an excellent candidate. Several days later, I returned and paid 360 000 yen ($4000 US) to undergo iLasik surgery, which is supposed to be state-of-the-art.
The operating room:
(
iLasik stands for the two stage IntraLase (laser eye flap cutting: the machine on the right) and Visix (customized map laser correction: machine on the left). iLasik, IntraLase and Visix are all registered trademarks of AMO (Abbott Medical Optics) Inc., the current industry leader in Lasik treatment.)
You can read about the procedure on many places online. But for the record, here are a few pictures from my surgery:
Don't worry, you can't blink during surgery. And with anesthesia, you can't feel a thing but I swear you can smell the burning as the laser zaps your eye...
Pressure ring is placed on the eyeball for IntraLase.
Can you see the semicircular cut the first laser made?
Visix zones projected on my eyeball.
Post-surgery, I was supplied with various eye drops for use five times a day for the initial one week period:
- Dexamethasone: an anti-inflammatory
- Antibiotic drops
- Hyalein and Hyalonsan to cure corneal laser cut and dry-eye symptoms
- Oxybuprocaine: anesthetic drops for pain
I ended up taking items (1) through (3) only. And after the initial 24 hour check-up, I was told I could discontinue (1).
After one week, I was cleared for sports again. You cannot spot any laser cut. And I'm down to using just Hyalonsan lubricating drops.
There are risks with iLasik of course. You can pick the best/most experienced doctor you can find (mine had done over 30,000 operations), make sure you're an excellent candidate and follow all instructions carefully.
For example, pupil size and corneal thickness are important parameters. People with large pupils are likely to experience significant night vision problems such as halos and starbursts. My pupil size is 4.88mm normal and 6.2mm dilated, so that helps to minimize those effects. Secondly, my corneal thickness is an above average 575 microns. After correction for my 5.75 diopter prescription, I still have around 450 microns left.
I'm told it will take perhaps 3 months for my final correction to take. Since it has only been just over one week, all I can point to are my impressions and the visual acuity testing results.
Impressions: Immediately afterwards, cloudy vision. Halos and starbursts are pronounced at night.
One day later: there is a slight but noticeable haze during the day but otherwise distance vision is serviceable. Night vision is better but not as good as with glasses or contacts.
One week later: haze is gone. Halos can be noticed but don't impede night vision. Same goes for starbursts. I am not entirely starburst-free with contacts or glasses in the first place either. Driving or riding at night is fine.
I hope these effects continue to diminish in the coming months.
Visual acuity: 1.0 in the Japanese system is equivalent to 20/20 American. (A figure higher than 1.0 corresponds to a rating better than 20/20.)
| | Before Lasik | Next day | One week |
| Right eye |
0.03 (Japanese) | 1.2
| 1.2 |
|
20/660 (American) | 20/17 | 20/17 |
| Left eye | 0.02 (Japanese) | 1.0 | 1.5 |
|
20/1000 (American) |
20/20 |
20/13 |
I'm told the vision might continue to improve and stabilize over the first 3 months. (I will update this table after the next check.)
Unfortunately because of my age, I still need reading glasses for computer use and for close-up reading. Next step? Investigate by means of a contact lens whether a separate CK operation is appropriate to fix my presbyopia or would it compromise my newly corrected vision too much...
Yesterday was the century ride (blog entry).
Tonight, I attended the sold-out England - Brazil soccer match in the 50,000 seat Khalifa International Stadium, ticketing courtesy of my friend Majd Sakr.
It's a gorgeous looking stadium:
Here is the view from the 500 Rials ($140) seats we got:
Yup, a little too far away to see the faces of the players despite my recent iLasik surgery.
For the second half, we ended up in some minor-VIP seating area. Free juice and a big difference in terms of viewing:
The stadium is part of the Doha Sports City Complex built for the 2006 Asian Games.
Next to the stadium is the 300m tall Aspire Tower shown here. (About the same height as the Tour Eiffel in Paris.)
Also, next to it is a large shopping mall (Villagio) - not shown here.
