High Degree of Myopia & Astigmatism

Postby nschweda » Mon Dec 17, 2007 7:11 pm

I recently had an evaluation for the possiblity of correcting my vision. My prescription is R -4.25 -7.00 005; L -7.25 -5.50 165. I was told originally by my optometrist that my cornea thickness was 550 in the right eye and 560 in the left eye. The LASIK Dr. told me my corneas were too thin, he explained that they were around 500 for both eyes. He encouraged 3 procedures; PRK, IOL and LASEK. I am confused because of the difference in cornea thickness by 2 different doctors. I am concerned because of the cost and whether or not it is worth it. Should I seek a second opinion?

Definately get a 2nd opinion and maybe even a third..

Different devices are more and less accurate in determining corneal thickness. Always go with the thinnest number. A surface ablation like PRK, LASEK, or Epi-Lasik would leave more margin for error.

Phakic IOLs are really not indicated. They are much more invasive than PRK or LASEK and are much better suited for someone with high myopia who is absolutely not a candidate for laser vision correction. An IOL (Refractive Lens Exchange - RLE) would only be appropriate if you are fully presbyopic, probably well past age 40.

Another opinion or two is always wise.

Phakic IOL or RLE

Postby nschweda » Tue Dec 18, 2007 7:54 pm

Due to thin corneas, severe myopia and severe astigmatism I am not a good candidate for LASIK. I have spoken with 2 doctors. One doctor wants to do a Phakic IOL and the other doctor will only do a RLE. I have heard that RLE is only recommended for people over 40 and who are presbyopic. I am in my early 30's and to my knowledge am not presbypic. I am not so sure I want to have my natural lenses removed at this time but I am not sure which is the best route for me to go especially now that I have 2 different opinions.

Neither a Phakic IOL nor RLE will resolve your astigmatism. The moment you have RLE you will require reading glasses to see anything near you, even the dashboard on your car. Neither of these options are likely to provide a satisfactory outcome, and don't accept the "multifocal IOL" theory of accommodation. They have their own set of problems.

Also, your high astigmatism and thin corneas may be a sign of keratoconus, which is another contraindication for Lasik, PRK, LASEK, Epi-Lasik, and P-IOL.

In my opinion you should be evaluated by a corneal specialist before considering any type of elective ocular surgery.
