Q:  I had a failed attempt at monovision and a re-surgery to eliminate it. After being told what a great result I had, I found out I was really nearsighted in one eye and far sighted in the other with lasik induced astigmatisms in both eyes. After months of dizziness, nausea and headaches and disability, I went to an OEP optometrist who says my corneas are as wavy as funhouse mirrors. RGP's may be my only hope of functioning normally.Why did this happen and what would you call it? A: I would recommend getting another opinion, just to be sure about the outcome. Further surgery may be possible. Andrew Caster, MD www.catervision.com

Q: My daughter had custom lasiks a couple months ago. She is suffering from dry eyes now and her vision is good some days and some days its not. The doctor that done it says it could take up to a year for the eyes to heal and stabilize. Is this correct? He told her to keep pouring eye drops in the eyes to keep them moist. I'm very concerned. She was legally blind without her contacts before she had this done. Her eyes get real bloodshot and I worry as a mother that her eyes have been ruined. Can you give me any input? Thanks, S. Jones A: There are several treatments that are available for dry eyes, including flaxssed oil pills, night ointments, and tear duct plugs. She should discuss these with her doctor or see another doctor. Andrew Caster, MD www.castervision.com

Q: I'm facing cataract surgery and have been asked to decide whether the affected eye should be made nearsighted or farsighted. Can lasik or PRK be performed after the IOL implant to correct the eye perfectly? If so, which option is best? A: Yes, Lasik can be performed after cataract surgery, if needed.

I have a degree of -6.5 and astigmatism of around 3. Since I am a hemophiliac deficiencies in factor ( 8) I am confused to take what treatment that is the best and most suitable for my condition.

Q: hi, i am currently 18 years of age and am interested in getting laser eye surgery because i demise glasses which i am forced to wear at work. my question is how safe is it to get laser eye surgery if my eyes are not exactly stable? I think in the last year and a half my eyes worsened by .25... both my eyes are the same 3.00 and 3.00. They use to get worse by .25 every year but are slowing down now.. my other question is what is the recovery time because i actually work at syncrude canada (big oil production plant in canada) (plus I am a dilivery driver, not welder or electrician or anything), but the thing is that the air is quite dirty there.. if I wear safetly glasses constantly how long would it take for my eyes to become safe again (without safety glasses)? thanks; Cody A: Laser eye surgery will not stop your eyes from changing. If they are changing, you may need an enhancement at some time in the future. Most people return to work the next day. You might want to take a couple of days off.
