Q: Hi, I am researching about LASIK for my 8th grade graduation project. It is a very important project that I need to complete to graduate. I was wondering if you could please help me answer some questions for my project. I would really appreciate it so much!! Below are some questions I really need help on: What positive impact does LASIK have on the society? Thank you so much for your time! I really appreciate it!! From, A: If you would like to call me, at 310-274-1221, I would be very happy to answer all of your questions. Andrew Caster, MD Email: March 23, 2006 Q:I've been wearing contact lenses for about 2 years now and currently my degrees are -4.25 on both eyes. I don't know if thats bad or not and whether I should get lasik surgery or not. I hate wearing ccontacts and just want my vision to be normal again. I am looking into getting lasik surgery but REALLY REALLY afraid that I might become blind as a result. So what are the chances that I might lose my vision permanently and what are the percentage of patients that went blind after surgery? Would you say that Lasik is a very safe procedure? Are the chances of losing vision very high? A: Although over 10 million Lasik procedures have taken place in the United States, I am not personally aware of a single person that has become blind from Lasik. It is theoretically possible, but obviously the chances are very, very low. Andrew Caster, MD Email: March 25, 2006 Q: Can excessive use of a computer cause my vision to decline from 20/20 to 20/30? Can LASIK correct this? A: We do not know for sure why some people become nearsighted, and whether computer use plays a role. Lasik can correct the problem. Andrew Caster, MD Email: March 29, 2006 Q:
Can your dominant eye change from one eye to the other with lasik surgery. A:
Yes, the dominant eye can change. Dominance in the eyes is not as firm as handedness. Many people only show minimal or even no dominance with the eyes, and it certainly can change. Andrew Caster, MD Email: April 03, 2006 Q: I was diagnosed with having keratoconus 7 years ago. Recently, I have started to wear gas permeable contact lenses (less than 6 months). A: Lasik is best avoided in people with keratoconus. Lasik without a flap can be performed, but the keratoconus will still progress, and there is some concern that Lasik without a flap may cause more rapid progression in some cases. We really don't know for sure. So I would recommend against laser vision correction at this time. Andrew Caster, MD Email: April 04, 2006 Q: I am 23 years old, and have had a lazy eye since my mom noticed it at about 10 months old. I have not taken care of the problem and it has been untreated for about 10 yrs. My left eye is the lazy eye and when closing my right eye all I see is severely blurred vission. I suffer from realy bad headaches everyday,dizziness and nausea. I feel my condition getting worse. Is there any surgery to correct the problem or so that my left eye could move left or so that I dont look cross eyed. Thank you. A: You need to be evaluated by an ophthalmologist to determine if there is treatment for you. Andrew Caster, MD Email: April 05, 2006 Q: Hello: A: Lasik can make the eyes more dry in some people, at least temporarily but sometimes on an ongoing basis. Lasik without a flap seems to have much less effect upon dryness, so that might be the better option for you. Andrew Caster, MD Email: April 06, 2006 Q: I had cataract surgery in 1992. My vision at distance (beyond reading length) is blurred, and I use prescription eyeglasses to see clearly when driving or playing golf. I would like to be able to see a golfball hit a green @ 150 yards. Can lasik accomplish this? A: Yes, assuming that the other parts of your eye are healthy. Andrew Caster, MD Email: April 07, 2006 Q: What does the number mean in regards to your corneas? After my exam, I was told my number was low - indicating a thin cornea - They didn't explain what that meant. A: Some people have thicker corneas, some have thinner ones. If your cornea is too thin, then laser vision correction is not an option. Andrew Caster, MD Email: April 13, 2006 Q: I am planning to go into the US Army in about a year. I do not want to worry about having glasses on while doing different activities, since no contacts are worn in the army. A: Many, many people in the armed services have had Lasik or Lasik without the flap (PRK). Andrew Caster, MD Email: April 14, 2006 Q: I am 20 years old and I want to know if I can have LASIK surgery. I have astigmatism. A: You need to be evaluated by a Lasik specialist. One of the issues for a 20 year old is that it is best to wait until your eyes have stopped changing. Sometimes this happens at age 15, but sometimes not until age 25 or so. Andrew Caster, MD Email: April 14, 2006 Q: Is there any way at all to change the color of one's eye through surgery or any other way? Recently I have heard that there are eye drops that can change the color of one's eye. Is this possible? A: There are glaucoma eyedrops that can change the color of the eyes in some people, but this is an unwanted side effect. There are no drops to purposefully change the eye color. Andrew Caster, MD Email: April 15, 2006 Q: How long do the results of lasik last for? I have friends and coworkers who have had lasik performed several years ago. A couple of them still see great, but a couple of my other friends say that their perfect vision is slowly fading. One friend had lasik performed 3 years ago but needs to wear glasses again when driving. What causes the results of lasik to fade away? A: Lasik will not stop the eyes from any naturally occurring changes that they are programmed to develop. Therefore, we want to wait until the eyes stop changing, as they often do, in the teenage years and which can sometimes continue into the twenties. Sometimes people in other age groups will experience a change in their vision, which Lasik cannot stop. Also, Lasik will not stop the loss of near vision (presbyopia) that occurs in midlife for which people use reading glasses. Andrew Caster, MD Email: April 16, 2006 Q: I had lasik surgery 4 years ago, I'm 49 now. I had my left eye done for distance and the right for reading. The reading eye is now becoming less functional. Can I have it re done for reading again or can it be re done for distance, and I'll just get reading glasses or a contact lense. Melody A: It can probably be adjusted either way: for better distance, or better reading vision. It is your choice. Andrew Caster, MD Email: April 17, 2006 Q: I have lasik in my right eye( -3.25 _ -1.25 _ 20) on 3/12/2006 and after that i did have astigmatism = 0.7 so I did enhancement on 4/15/2006. I think it is ok but I still find that as I try to read text it is still not clear and difficult. Is this normal and how do I know that there is nothing wrong this time or that I may have irregular astigmatism or any thing else? A: I like to wait three months before reaching any decisions. The eye is changing as it heals, and it really teakes at least three months before things are usually reasonably stable. Andrew Caster, MD More Lasik Email Questions Pages |
