Q: I had Interwave surgery in November of 2004. Everything seems to have went well except for one thing. It seems that around mid afternoon my eyes want to close on their own. They physically start to draw shut and I can not control them. Is this due to the surgery? I've never experienced this before. I did have to have punctal occluders put in the bottom. Is there a chance of nerves being damaged because i also now experience my right eye twitching constantly. It hasn't stopped since Nov. Thank you,Angelique Herrington A: Your eyes may be dry. Otherwise, there is no connection. Andrw Caster, MD

Q: My optomoterist told me he saw that I had corneal guttata. Would I still be a candidate for lasik surgery? He told me he didn't know. A: I would recommend a conreal endothelial cell count. If it is fine, then Lasik is okay. Andrew Caster, MD

Q: Dear Dr. Andrew, Frist thank you very much for your reply to my email before my surgery in San Diego. Now I have a couple of more questions about the post-operation recovery. 1. My vision right after surgery were 20/20. And the surgeon told me due to my prescription (left eye, -4.84D, -0.41 astigma, right eye, -5.81D, -1.43 astigma), it will take 3 months for my visions to stablize. Will my vision get better or worse with time passing by in this 3 months? 2. Should I reduce the usage of computer, especially CRT monitor? I feel dry eyes and poorer (relatively) visions after working on computer the whole day for couple of days. If I swicth to a flat panel monitor or a laptop, will that help? What else can I do to prevetn my visions from going worse when my eyes are healing? Really appreciate your help. Regards Lee A: Your vision will take several months to stabilize. Sit farther from the computer, and rest your eyes every 30 minutes for 5 minutes. Andrew Caster, MD

Q: I had lasik about one year ago. I am noticing my vision at night time is starting to not be quite as clear, is this normal and what should I do? A: I would return to get an evaluation. Andrew Caster, MD

Q: If you have had lasik surgery in the past and find yourself depending on eye glasses again, can you have lasik eye surgery again? If you can, are there any complications that you know off and have other people experienced the same problem? A: Yes, you can have repeat Lasik. The possible complications are very similar to the first surgery. Andrew Caster, MD

Q: I only started wearing glasses at 43 years old. I started noticing reduced vision prior to that. Since then, I have changed my prescription once, one year after my first visit, and now they seem to have changed again. If I have Lasik, will my vision be permanently corrected, or keep changing? A: It depends. You sound as if you are hyperopic, and if so, Lasik will probably correct your distance vision without furher significan change. Andrew Caster, MD
