Q: My husband is interested in lasik and is a candidate. All the information received shows results at one year. What are the long term results? He is now 42 will he ever have to wear glasses again if at one year he has good vision?How far post op is there data on effectiveness? Are there any articles on long term results I can access via the internet? A:  There are long term studies which show stability after the first year. A few patients will have a change in the vision, but a few percent of people who don't have this surgery will also change as well. So Lasik does not stop naturally occuring changes in the future. Also, readers will be needed, usually around age 45, whether or not Lasik is performed. Andrew Caster, MD

Q: Hello Doctor, My name is Vishal. I am interested in getting a LASIK procedure done at your institute. I am Myopic since birth. I currently use contact lenses of -13.5 spherical with -2.5 cylindrical in prescription. I wanted to know what the investigative suitability procedures are for getting LASIK done. Is it safe to get the full defect corrected, as I have heard that at such a high power the lenses are streched and thin as it is and further removal of tissue from it would weaken it. Also how long would all the investigative procedures take to be done? Also if you are please able to send me some literature in relation to the procedure, I would be grateful. Thanks in advance Vishal   A: We do not perform Lasik on that prescription. The phakic intraocular lens is the best solution. Andrew Caster, MD

Q:  Hi, I am wanting to get Lasik and I had a new eye exam a couple months ago, I wear my contacts a lot more than my glasses so when I had my new exam I only bought contacts, I have to wear my glasses from my last exam for a week before I go to my appointment, my vision only changed a little, will this interfere with the Lasik, Thanks A: No. Andrew Caster, MD

Q: Sorry for the limited information, but I was wondering if it is possible for a person with Right: sphere +6.00, cyl. -1.25, axis 020, prism 4.5 base BO & Left sphere +7.25, cyl. -1.75, axis 165, prism 4.5, base BO vision to get LASIK. Is it possible? Will i still have to wear a lessened prescription afterwards? I am just trying to research all of my possible options. I appreciate all of your assistance on this matter. A: Lasik will not provide a full correction. Andrew Caster, MD

Q: Before I had the lasik procedure done, my vision was 20/450. I had the surgery done in July 2004. on November 9my vision was 20/25 and 20/30. Because the vision was noticably blurry in my 20'30 eye, my surgeon and I decided to correct this eye. I had the surgery done 6 days ago. Since the day of my surgery my vision has been 20/100.I have not noticed one ounce of change in my vision since the day of my surgery. I am so worried! Why did my vision regress so much? and will it ever reach 20/20? please contact me ASAP. my worse nightmare has happened! I HAVE ALSO HEARD THAT YOU CAN ONLY HAVE LASIK SURGERY DONE TWICE WITH OUT HARMING YOUR EYES. IS THIS TRUE? A:  There is no limit to how many times you can have Lasik, except that a certain degree of thickness must be maintained. Your eyes are still healing, so I would not be overly worried at this time. Andrew Caster, MD

Q:  I am a 34 year old writer who is has myopia (-2.75/-3.00) and have been considering laser surgery. However, because nearly all my work is close up, and because my close vision is near on perfect, would you recommend I take the risk of surgery? I have heard that sometimes, when myopia is corrected, far-sightedness then occurs. Although I would like to be free of glasses and contacts, it is better that I am short sighted than long sighted for the work I do. A: You are well below the presbyopic age, which is 40-50, but that is in your future. After Lasik, at least until you get presbyopia, you should see up close as you do now ith your contacts or glasses on. Andrew Caster, MD

Q: I've had the Intra-Lase Lasik surgery about a week ago, but now see some acute "shadowing" of objects (three golf balls in flight, for example, when there's really only one in the air)--and the typical "haloing" of lights...are these typical, and how long are they supposed to last in typical situations before I should get concerned? A: These could last for several months. Andrew Caster, MD

Q: My eye doctor, that I've been going to for years recommends I wait to get corrective surgery done because my prescription is really high (-6.25) that if I get LASIK done, I still may have to wear a low power of glasses. Is this true? If this is true, is there a procedure coming soon to correct high levels of nearsidedness? Thank you A:  Your prescription is fairly typical for Lasik patients, so I do not think that you are getting accurate information from your doctor. Andrew Caster, MD
