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: 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: 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: I have astigmatism and I was told that having Lasik surgery would possibly make the situation worse. I was also told that astigmatism is where the cornea is being stretched out and eventualy the cells with pop. Can you please set me staight so that I will know if I could get corrective surgery for my eyes? Thank you for your time. Sightlees in Vegas TLC A: Get a second opinion. Andrew Caster, MD

Q: I am thinking about having PRK but wanted to know if I will be required to wear a contact lens after the surgery or can a patch be used instead. I have a phobia to contacts and have never worn them. Thanks A: Contacts are much better; a patch won't work well. Andrew Caster, MD

Q: My daughter does not need contacts, but she wants them to look pretty? Can this effect her vision? A: Only if she develops an infection. Andrew Caster, MD

Q: would i be able to get the surgery done if i am 16 years old? A: You must wait until your eyes stop changing, which may be in the late teens or early twenties. Andrew Caster, MD Caster Eye Center Beverlly Hills, California www.castervision.com

Q: I am going to have lasik surgery next week. I have qualified for custom lasik and am try to decide rather to have custom or contemporary. I understand that custom fixes sharpness issues like halos around lights and seeing specific details in faces and such. I have no problem with this issue now so would it be ponitless to have the custom lasik, or is this a problem that can develop after conventional lasik. A: It is a problem that can develop after Lasik, with conventional or custom treatment, but it is less common after custom treatment.

Q: I have been examined and told that I qualify for PRK and Lasik. I am in the military so it is covered finanically. I have done my research and understand both procedures. I am still uncertain which to choose. I want to do what is best in the long run for my eyes. Any input is appreciated. Thank you! A: They are equal in the long run. Lasik definitely heals up faster. However, PRK may be safer for some people in high risk situations where trauma may occur to the eyes, such as in combat. In this case, Lasik may be a better choice.
