I also took the lasik over a year. At that moment, I have more than 900度近視. May I share my experience here:
1. My vision is not as good as before during the night time, particular if the light is not bright enough. I need to turn on all the lighting if I need to have some readings.
2. I feel my eyes a little bit dry if I work long. Thus, I always to have yawn to watering my eyes as I don't want to too depend on the eye drops.
3. Fully be aware all the issues for the period before the surgery and after the surgery.
4. Taking consideration for the risk you will encounter
