Dear Nancy, Than you for your email. Problems with night vision are more frequent with near-sightedness than far-sightedness. You may have problems with light sensitivity in the beginning. We usually give a low dose of Valium prior to the procedure. Sincerely, Dr. Alexandra Chebil The Lasik Center

Q&A: Can I expect 20/20 from LASIK eye surgery, how long will it last and what are the risks?

Question:

Doctor: I would like to ask you what the percentage of 20/20 or better is if my eyes are -1.00 and -1.25.How is the rehab. for the eyes? After the surgery, will my eyes ever even slightly go worse?Are there any risks? Thanks Sincerely, Steve Shelton

Answer:

Alexandra Christine Chebil, MD, FRCSC - LocateADoc.com

Dear Steve, Thanks for your e-mail. 98% of patients I have treated have obtained 20/20 distance vision. The treatment will correct your vision as it stands today, but cannot predict further changes (most eyes are stable even 10 years later..as long as your prescription was stable for one year prior to treatment). Healing is very fast- most people return to work the next day. Like any surgery there are always risks.. you may wish to visit my web site at "www.lalasik.com" or "lzr.com". Thanks Dr. Alexandra Chebil

Q&A: If I had RK years ago and now my sight has deteriorated, is RK or LASIK eye surgery a possible solution for correction?

Question:

I had RK done over 10 years ago and now it is starting to deteriorate. My current (1 year) prescription is R.E: +350 -200 x 180, LE: +350 -250 x 5, add R+l +250. Is PRK/LASIK an answer ?

- George

Answer:

Byron Stratas, M.D., F.A.C.S. - LocateADoc.com

Yes. Our results on patients who have had RK have been very encouraging. All of them are very happy with the improvement LASIK has given. Your type of refractive error appears to be best corrected by the "crossed cylinder technique". The software to do this is not FDA approved so it is not currently available in the USA.

Q&A: Is there a cure for bad "low light vision" as a result of LASIK eye surgery?

Question:

I had Lasik in Sept 98 and was corrected to -.5 and -1.25 with some residual astigmatism in one eye. My dim light vision is not as good as before which is a problem driving into underground parking garages. Is there a cure for bad low light vision?

- Libby

Answer:

Byron Stratas, M.D., F.A.C.S. - LocateADoc.com

The problem may be your residual myopia. Is it improved when you wear glasses to correct the residual myopia?

Q&A: How much of your cornea is used in the LASIK procedure and is there a minimum cornea depth required?

Question:

I am considering having the lasik procedure. Can you tell me how much of your cornea is used in the procedure. Is there a minimum cornea depth that is required for the procedure. I had all the tests done and I think my cornea is only 47 and I understand usually the cornea depth is 53. Am I taking additional risk because of my cornea depth.

- Lisa

Answer:

Alexandra Christine Chebil, MD, FRCSC - LocateADoc.com

Hi Lisa, In answer to your question, the usual corneal flasp in Lasik is 160microns. The remaining cornea should be at least 200 microns. So a total of 360 should remain after the laser treatment. If you cornea is only 470 microns you could have lasik done for around -1.25 of myopia. This might be different if you are far-sighted and not near-sighted. You might need to have PRK done.

Answer:

Alexandra Christine Chebil, MD, FRCSC - LocateADoc.com

Thank you for your question. If your prescription has not stabilized, it is preferable to wait before having Lasik done. (I suggest one year of stable presription). Other procedures are not recommended for high myopia (corneal rings). You may wish to consider daily disposible contacts until your prescription is stable. Thank you Dr. A. Chebil (800) 841-3717

Q&A: What is the difference between LASIK eye surgery and PRK and why would you choose one over the other?

Question:

What is the difference between lasik and PRK? It seems that they both treat the same ailment. why would a person want one over the other? ...

- Domacata

Answer:

Alexandra Christine Chebil, MD, FRCSC - LocateADoc.com

Dear Domecata, Thank you for your letter. Although PRK and Lasik both correct for the optical problem of the eye, Lasik gives the same result much faster (12 hours and not 7 days for 20/20 vision as with PRK) Therefore, people are requesting the faster healing time. Also, any complications with Lasik usually occur only during the first 24 hours, but with PRK can occur up to six months after a successful treatment. If you are in the LA area we would be pleased to see you for a free evaluation. Thank you Dr. A. Chebil M.D. (800) 841-3717 The Lasik Center

Q&A: What should I do if after PRK Excimer laser eye surgery I still have a hazy view and my doctor wants to scrape my eye?

Question:

I had PRK surgery done on my right eye a week and a half ago. I have hypermetropia (this is how it is called in Spanish). I chose this procedure over lasik because my ophthalmologist said it was safer and more precise. My operation was on a Thursday and my doctor said that by Monday my eye was to have healed and he would be removing the protective contact lens. On Monday he said that there was a small part in the center that had not healed and that we would wait until Wednesday. This happened again on Friday and yesterday (Monday) he told me that if by Thursday it had not healed he wanted to scrape my eve again. I am not seeing well through the operated eye. Definitely worse that I did before the operation and my vision is very hazy. I also have acute discomfort all of the time. I am not willing to have this doctor scrape my eye again without a few other opinions and I am willing to travel wherever I have to in order to confer with the leading authority in the field (I live in Puerto Rico), The problem is finding out who the leading authority is. ...

- Keller

Answer:

Alexandra Christine Chebil, MD, FRCSC - LocateADoc.com

Dear Keller, Thank you for you letter. It sounds like the surface layer of epithelium(which is removed during PRK) has not grown back yet. Until this tissue heals completely it is normal to see "hazy" and to have discomfort. Sometimes the only way to help the tissue heal is to rescrape the cornea. I suggest that you continue with your original doctor until this healing is complete. Hypermetropia always takes longer to heal than myopia so you should be patient, I'm sure things will get better soon. Sincerely, Dr. Alexandra Chebil
