High Myopia w/ Astigmatism

Postby johnson1615 » Thu Feb 22, 2007 3:35 pm

I am considering vision correction and am looking for someone with similar vision who has had correction.
My eyes are -10.25 and -11.5 with slight astigmatism.
The doctor uses the intralase FS60 flap laser and the Allegretto wavelight eximer laser. Does anyone have experience with these.

I was turned down by one doctor who said that while my corneal thickness was fine, that he felt my eyes would be too flat after surgery and I would not be able to wear contacts??????? His counselor actually said this and I never was able to speak with the surgical doctor. The Dr. who did the exam was not the surgeon.

I am going to my new doctor next week. I have met him through a seminar he held and he spoke at length with all of us and one on one. He has been doing refractive surgery for 27 years and I feel very confident with him. He has told me that with my high myopia that prk or implantable lenses may be the best alternatives if lasik is not an option.

I would really like to hear from someone with similar vision and hear about your results.

Thank you,
JJohnson

I did not have similar refractive error, but I have provided information to many in your situation.

To reduce myopia (nearsighted, shortsighted) vision the laser flattens the center portion of the cornea. To remove 11.00 diopters of refractive error at least 130 microns of tissue will need to be removed. Depending upon the curvature of your cornea before surgery, this may make the cornea very flat. Not being able to wear contacts would be only part of the problem. Poor vision quality and loss of contrast sensitivity would possibly be another.

Not all lasers use the same profile when they remove tissue. The Allegretto is known to leave a more prolate cornea after surgery and this would reduce the flattening effect in your case. Discuss this difference with your surgeon.

If you are well past age 40, then Refractive Lens Exchange (RLE) may be an appropriate option, but due to myopia caused by an elongated eye you may be at an elevated risk for retinal detachment. Discuss this with your surgeon and you should probably have an evaluation by a retina specialist before any elective eye surgery.

A Phakic Intraocular Lens (P-IOL) is another option, but a concern will be if there is enough room inside your eye to hold the P-IOL and not disrupt the surrounding cyrstalline lens, iris, and cornea. These measurements can be made before surgery.

Lasik is a possible method for correction, but it would be reasonable to expect significant regression of effect that would require enhancement Lasik surgery after a few months to "fine tune" the correction. For you Lasik would be a process, not an event, no matter which laser is selected.

Thank you for the information.
The doctor's fee for lasik, etc. is considerably higher than other docs in the area but he does offer free enhancements for 3 years and you do always see him personally. If my vision will be a process I see this as a big plus.

I am going to the first doctor's office this morning to get my eye measurements from them and would like to post them to get your thoughts. Thank you!

I went to the first doctor's office today to get specific information from my exam. I didn't really ask for anything in writing, I just wanted to know the thickness of my cornea, pupil size, prescription, etc. They would not give me any information. I had to fill out a long form requesting the information and now it has to go to the surgical doctor for him to decide to release the info.??

I got the impression I won't be receiving this info any time soon, so I guess I will have to wait until my exam with the new doctor next week. I will make sure I do not leave without it this time.

The information you requested should be readily available and the patient always has a right to the information in his or her medical file. I find it rather odd that the doctor's office would have in place such procedures to give simple information.

So far, I still have not heard from them.............

I have had my exam at my new Doctor. it was very thorough.
I am having the lasik surgery today in about 3 hours. Am very nervous.
The doctor was very supportive of my concerns.
He is using the Allegretto Wavelight and Intralase.
First doctor had concerns about the K factor. this doctor demonstrated that this wasn't an issue for me with the Allegretto. Also, my cornea thicknesses were 555 and 557. (Myopia of -10.75 and -11.5.)

My pupil size is a little large,7.5, in total darkness but 6.0 in small amount of dim light. We discussed several options for this is night driving is an issue after surgery.

Will let you know results soon!!!!!!!!!!!!!!!!!!!!!!!!!
