Q: had lasik done 2 weeks ago..i am undercorrected according to my doctor....he said enhanchment can be done in several months. my worry is that i had -6.50 and -5.00 in both eyes before lasik..now my eyes are about 20/70 and dr prescribe temporary glasses for me for driving until enhanchment can be done..i got my glasses back today and i still cannot see clearly..just little better in left eye....when he was tryng to my reading on me to get glasses i was having problems seeing anything clear..he said at that time my eyes are still healing and that is why cannot get a good reading for glasses..my close vision is now excellent with reading glasses. i am worried that i have lost the ability to get my corrected vision back forever after laser surgery..any thoughts would be appreciated. thanks johna A: I would not be worried at this time, as it can take several weeks or sometimes months to stabilize. If you continue to be concerned then get a second opinion. Andrew Caster, MD

Q: Hi. I've had a consultation for laser eye surgery and have been told that I have larger than normal pupils in dimmed light. I think around 8-8.2mm. Does this mean that I will more than likely have glare/halos or is there a chance that I may not? They said that it would probably no worse that what I already experience with contact lenses and glasses - is this true? If so surely I'm no worse off. Also could I wear glasses when driving to correct the glare/halos. Thank you in advance for you help. A: Some patients have glare and halos after Lasik. Usually it is correctable with an enhancement, but not in all cases. It is not clear what the role of larger pupils is in resulting halos, but they may play some role. I tell patients that larger pupils are a risk factor for halos, though this is not defintitely proven. Andrew Caster, MD

Q: I had LASIK; ladarvision; about two weeks ago. My left eye is fine. Great vision. My right eye is terrible. Very blurry vision. I have been back three times, and I am scheduled to go back in a week. The doctor says that the right eye is very dry and swollen and that is why the vision is bad. She says the flap is fine. Is this true? Should I get a second opinion? How long will it take before I know if this is going to clear up or not? Currently her advise is to continue to use non-perservative artificial tears and Muro 128 5 three times a day. Is there anything else I should be doing? Thanks. A: It might ease your mind to get a second opinion, but dryness and swelling certainly do occur. Andrew Caster, MD

Q:  I had Lasik 1 year ago so can I have custom Lasik now?? A: Yes, if you need it. Most probably you will not need it. Andrew Caster, MD

Q: I am farsighted with astigmatism. I am 51 yrs.old. What is the best lasik for me? I had a consultation. They said I could correct for distance and then I would just need reading glasses. Or I could fix close up but then it would be blurry for far away. ( That did not sound good to me.) Or I could fix one eye for far and one for close up. What do you think about the last one? Does that work well and is it bothersome? I actually made the appointment for the 1st solution but I am thinking about doing the last solution of one eye far one eye near. What do you think? A: The best solution is what works best for you personally. Your doctor should show you with glasses each of the options and then you can make an informed choice. Andrew Caster, MD

Q: I assume this is probably for people looking to get the surgery done but it's worth a try. I had PRK done (here in Canada) last Friday, 10 days ago. So far I am extremely disappointed with the results. My Rx prior was about 3.5 diopters, moderate at worst. Now, I am unable to see clearly at any distance. Faces, numbers and street signs are nearly unrecognizable. My doctor here tells me not to be worried but (admittedly) its been awhile since he's done a PRK and doesn't remember well how long it takes to heal. Do I just keep waiting? Thanks in advance, Andrew A: PRK can take several months to obtain optimal vision. Andrew Caster, MD

Q: I have had laser surgery 9 days ago. i am 50 years old and fit and healthy. i was shortsighted. since the surgery, i have had burst blood vessels in both eyes, still present now, do i keep using the drops and saline solution. my vision is not as good as i expected. my eye muscles are taking time to settle. i have seen my doctor once.i need reading glasses to see now and my distance vision is not sharp. i am not in pain. thanks jenny A: The broken blood vessels will usually heal in 2 weeks or so. Everything else you describe is perfectly normal. Andrew Caster, MD

Q: I am considering Lasik surgery. The doctor has given a mild to moderate recommendation for custom lasik as I have "thinnish" corneas.What information should I be looking for to help me make this decision? Given the procedure is twice as expensive as the regular lasik I obviously want to know if it's worth the extra cost. Thank you so much! A: There are a lot of factors, which I cannot go into here. Custom makes a subtle difference. If the money is critical, then most people can be satisfied without the wavefront custom treatment. Andrew Caster, MD

Q: How do i know im getting what i'm paying for ? What if complacations arise? Is that usually xtra? A: Typically, the fee involves the cost of dealing with complications afterwards, though many cutrate places will bill you extra. I would avoid those places. Andrew Caster, MD

Q: I had wave front lasik surgery about 1 year ago. my vision has greatly improved from -10 to a -1.75. I was suppose to have a second procedure performed to further correct, but my surgeon warned me about possibility of unstabilizing the eye. He explained to me about the region behind the cornea has slight deformation and he is not certain if it was the result of the surgery. If he goes ahead with another procedure he is afraid it can unstabilise this region. I consulted a second surgeon who told me he did not see a problem with the repeat procedure. He mentioned there was plenty of cornea thichkness & curvature to play with. I am confronted to make a decision by october 18th. My surgeon cannot quantify the risk factor of creating this unstability, which he explains can happen not right away but later on. Has anyone had experience with this & do you have any advice?? A: First of all, there is no medical deadline that happens on Oct 18. This is a medical decision, and that must outweigh all other factors. Do not do anything until the issues are clearly delineated. Consider obtaining a third opinion. Andrew Caster, MD
