Q&A: How can the custom-cornea technology help when the LASIK procedure over-corrected and my cornea is now too thin?

Question:

Thanks so much for your reply, Dr. Caster. God bless you. My question continues... I was over-corrected with the lasik initially leaving me with no reading ability and about 20/50 on good days with shadowing and the spokes and halos at night and dryness. If I now see without the double vision and need more power to see distance, my doctor wants to do the clear lens extraction and fit me with a rolled up plastic lens that is inserted into the eye like cataract patients get. This along with a gas permeable contact lens if needed after the lens is inserted would attempt to correct the dips and valleys in the scarred cornea when used with drops to fill in between the gas permeable contact lens and the cornea to help attain the distance vision I need. A cornea transplant is suggested in the future if I can't attain the desired vision with the lens insertion and the gas permeable contact lens. How can the custom-cornea technology help when the lasik procedure over-corrected and my cornea is too thin now for any further cornea work?

Your situation is more complicated than I was aware of. Of your cornea is too thin for any further laser work, then you cannot have any more laser work. The clear lens extraction may be useful, but has certain drawbacks. Make sure that you discuss this with your doctor. Andrew Caster, MD

Q&A: Will a clear lens extraction and a new plastic lens fix my inability to see distance as a result my previous laser surgery?

Question:

My right eye had an irregular flap cut with the hinge across the middle of the eye. The laser therefore zapped in the decentered position and it overcorrected leaving me with double vision and no close or far vision with halos and spokes on lights at night. A second different surgery by another doctor corrected the double vision but could not do anything other than hit the eye from the side with the laser to fill in some of the hole. I see now with difficulty but have just a little shadowing with my vision but still can't read or see distance well. Will a clear lens extraction and a new plastic lens fix my inability to see distance. I am 46 years old and would greatly appreciate your response a soon as you can as, I am in need of good counseling.

At this point, it is best to wait for a new technology called custom-cornea. All of the laser manufacturers are working on it. It will enable treatments of irregular corneas such as you apppear to have. A clear lens extraction will not help. Andrew Caster, MD

You need to have a custom ablation guided by a wavefront analysis. This will b e comercially available later this year. Untill that time I would do nothing. Replacing the lens will not address the problems that have been created with the cornea. The problems need to be reduced or eliminated.
