Q: Dear Dr. Caster, A: Theoretically, the flap could be moved with extreme trauma. After the first few months, this would be very rare. I have heard that a car airbag dislodged one flap (it also caused other extreme damage to the eye) and I have heard of a professional hockey player who was struck in the eye with a puck and it dislodged the flap. Then the flap must be smoothed back into place. Andrew Caster, MD Email: March 05, 2006 Q:Hi, I'm 21 years old and wanted to get LASIK surgery but my friends have been telling me to wait until my eyes fully mature. My vision has gotten worse every year so would it be useless to have LASIK done and have my eyes get worse the next year? A: Lasik will not stop the eyes from changing, so you want to wait until your eyes have stopped changing before you have the procedure. It usually happens by the late teens or early twenties. Andrew Caster, MD Email: March 05, 2006 Q: I am 26 years old with healthy retinas but a 487/476 corneal thickness, 5.2/ 5.8 pupil size and a -9.00 prescription. I realize that this does not make me an ideal candidate for LASIK but I have gotten several different opinions on which surgery would be the best for me. Almost all surgeons recommended Wavefront (one doctor told me that with my prescription it may not make a difference). I have also had disagreement on the procedure with some saying I could do LASIK because Wavefront saves corneal tissue. Other doctors have recommended LASEK or PRK. Which would be the best for me? Also, research I have done indicated that PRK is best for mild/moderate myopia only. Is this a consideration as well? Thank you in advance for your help. A: For most laser systems, wavefront uses more tissue; that may be different with the Bausch and Lomb system. There is disagreement about the minimum tissue that must be left with a PRK technique. You may or may not have enough tissue. I would not recommend Lasik with your measurements. The more correction that is required, the greater the variability and hence the higher the enhancement rate and side effect rate. Andrew Caster, MD Email: March 05, 2006 Q:
I have an 8 year old daughter that has astigmatism in her right eye more than the left eye. When I took her to the eye doctor this year, he said it got worse from last year. Her eye vision is 70/35. They prescribe glasses but then the doctor tells me they put only half the prescription because she is too small for the whole prescription. Can you please help me and give me advice or somewhere I can take her. She has full medical, and we live in the Indio, CA area. My fear is my daughter is getting worse fast and she tells me, why can't I see right. I don't know how to explain to her, shes so little. A:
I would recommend that you find a pediatric ophthalmologist. There certainly is one somewhere in the Coachella valley where you live. Andrew Caster, MD Email: March 06, 2006 Q: I'm 25 and thinking about having Lasik. My prescription was stable for a year until this past November, when it worsened in each eye by only .25. I also work in front of a computer screen all day. Am I still a good candidate? Will my vision deteriate after lasik due to computer work? A: 0.25 change is considered minimal and would not prevent you from having Lasik. We do not know what causes the eye to become more nearsighted. Some people who work a lot at computers do become a little more nearsighted, but the vast majority do not. Andrew Caster, MD Email: March 06, 2006 Q: Hi, Kaandy A: There is nothing you have said that indicates that you cannot have lasik. You may choose to wait another year to see if your eyes have stopped changing. Most people go back to work the next day after lasik, but I would work only a few hours during the first few days; you want to be careful that your eyes stay moist. Andrew Caster, MD Email: March 08, 2006 Q: Dear Dr. Caster, I would like to ask one question about the vision surgery: the surgeon I have asked has told me to wear eyeglasses for one month before doing the corneal measurement (since I am wearing contact lens (soft) all day long. Does the contact lens modify the thickness of the cornea? Thank you in advance and best regards, A: The contact lens can cause minor changes, temporarily, in the thickness and in the curvature of the cornea. Andrew Caster, MD Email: March 08, 2006 Q: I will be 39yo in 2 months and am considering LASIK surgery and need advice. Some history: around age of 5 developed OD strabismus [in-turning] for which I was patched. Had the OD strabismus corrected in 1987 but am still left with the amblyopia. The alignment of my eyes is almost perfect. I have significant night halos that are decreased by 90-95 by use of glasses. My RX is OD: +5.75/-2.75/176 and OS: +3.50/-0.50/169. Corneas are 560+mm thick and the "k value" was good enough that no one was concerned about "button holing" the cornea with use of the microkeratome. Pupils dilate up to greater than 9mm [9.3mm if I recall correctly] My questions: 1) is it better to have the flap made by intraLASE technology since I need quite a large flap b/c my surgery occurs on the corneal periphery? 2) What laser? I am concerned over a) optical/treatment zone size, b) transition zone - helps prevent night vision/peripheral light refraction problems and c) beam size - smaller is better correct? Then there is the ability to have a custom wavefront procedure versus standard lasik. I've done research on the Alcon Ladarvision, VISX S4 [IR] and the Allegretto wavefront lasers - I'm sure there are others. What, if any, laser technology will best address my vision correction needs. Lastly, my expectation going into this was to just knock a couple of diopters off [have it equal the left] of my right eye to improve the cosmesis when wearing glasses. Was not really considering having the left eye done. I now realize that the night halos will likely not be improved by the surgery b/c of multiple factors [pupil size, treatment zone limitations, etc. . . ] but will the use of glasses at night [for driving] post-op decrease the halos as they do now? Thank you. A: You could have surgery on the right eye to make it more equal in prescription to the left. It really makes very little difference which technology you use regarding IntraLase or keratome, or the three lasers you mentioned, all of which are very good. It is really more a matter of surgeon preference than some easily measureable difference in quality. My pesonal preferences at this time for you would be Alcon LadarVision with the Bausch and Lomb keratome. Andrew Caster, MD Email: March 09, 2006 Q: If I have myopic with no astigmatism...does this fix my night blindness as well? A: The vision at night after laser vision correction is most often similar to the vision before the surgery with your glasses or contacts. Andrew Caster, MD Email: March 09, 2006 Q: I have decided to have Lasik surgery in 2006 (have already put the money in my flexible spending account) and also want to have an eyebrow lift. At my Lasik consultation, I was told to have the eyebrow lift first by at least 3 months. However, I am not ready to have the eyebrow lift and don't want to rush into the surgery. Will it be a problem if I have Lasik first and then later have the eyebrow lift? A: It should not be a problem. Andrew Caster, MD Email: March 14, 2006 Q: Back in 2001 I wanted to get lasik. I went in for the testing and the first thing the Dr. did was looked at my previous surgical scars. He told me that keloid formers are not eligible for surgical corrective procedures. Is this still a problem or are there alternatives? Today, I am wearing glasses due to the frustration with contacts not working with my active lifestyle (swim,ski,etc.). A: The more current information is that Lasik is not a problem for keloid formers. Many doctors are not aware of the newer information. Andrew Caster, MD Email: March 14, 2006 Q: Dear Dr. Caster, A: The flap creation takes about 20 seconds. There is a feeling of "pressure", but most people say that it does not hurt. You can also have the "Lasik without the flap'" though the healing pattern is a little slower. Andrew Caster, MD Email: March 15, 2006 Q: I had LASIK in 1998. My vision was great but then started to get worse about a year ago. I also have large pupils and have had night halos since the procedure. Could I have another procedure now to help both problems? A: You can most likely have a procedure to correct the distance vision, which may also help with the night halos. Andrew Caster, MD Email: March 15, 2006 Q: I have chosen and scheduled an appointment for an eye care center based on a recommendation. My questions are these: I noticed on one of your previous answers that you recommended against a "low-cost" center, as they will not be as thorough. I didn't have any reservations prior to reading your answer, but now I am a little worried, as the center I will be treated at utilizes advertisements in coupon books and is a lower cost than another local center I had contacted. Specifically, I have been asked to pay $1500 using the Nidek procedure, $2500 for Ladar, and $2900 for Custom Wavefront (all of these prices are for both eyes and are for using a microkeratome). I was opting for the Ladar, as I was recommended against the Nidek due to my astigmatism and pupil size (my pupils are about a 7.5, and my base curve is a 7.52 for the left, 7.50 for the right, with a diameter of 9.50 for both eyes, and a power of -5.50 for both eyes). I am under the impression that price ranges depending upon whom they're quoting and what the prescription is, which I assumed was an industry standard based upon the prescription of the applicant. However, I later contacted a "higher-end" facility that quoted me $2800 per eye regardless of prescription, and it was explained that price is based solely on the technology used. This makes more sense to me, though the price is presently out of my range. Is it in your personal opinion that I should wait until I can afford that higher price with the, presumably, newer technology and equipment and more "thorough" surgeon? In regards to recovery time, and assuming I proceed as planned with the current laser eye center, I am also scheduled to see a play the same evening after getting the surgery. Someone else will be driving; however, I was wondering if sitting in a darkened room would adversely affect my recovery. A: Sitting in a darkened room after surgery will not hurt your eyes; I usually recommend that people go home and rest afterward, but you could go to the play if you feel like it. You will more or less get what you pay for with this surgery. There are cheaper ways and more expensive ways to do the surgery, and genenrally the more expensive ways are better. This is your vision we are talking about, not some consumer item that you will only use for a few years and then replace. So don't scrimp on quality. Andrew Caster, MD Email: March 16, 2006 Q: Dear Doctor, A: I cannot comment about the jelly, because I cannot see it. But every person heals at a different rate and in a different pattern. If you heal in a pattern that results in some astigmatism, then you may need an enhancement. I would ask your doctor for an explanantion of what is happening.
