Refractive surgery after postlasik ectasia is it possible with PRK?
♥ 0 |
Hello, I am a 38 year old patient. In the year 2000 I underwent surgery for myopia with Lasik (I had 2,50D in each eye). Everything went well but over the years I progressively detected a deterioration in my visual acuity until last year I was diagnosed with post-lasik corneal ectasia. The topographies gave very high parameters in astigmatism of 6D and 5D in each eye. I had ring implants done 2 months ago and my vision has improved a lot. The cornea has responded very well and the topographies come out with lower astigmatism parameters. My question is if it would be possible to retouch with PRK those few diopters that I have left to have a perfect vision and then do crosslinking to strengthen the cornea, taking into account that my corneas have a good thickness of 570 microns approx. I have read on the DR VErgés website as a possibility to consider and what some ophthalmologists are doing with success so far or if for the moment it is better not to touch that cornea? Perhaps an ICL implant would be more advisable? Placing another ring on the cornea could improve my vision even more since they only placed one and I have read that there are cases where 2 rings are inserted? Can I hope that crosslinking improves my vision? Thank you

Hello and thank you for submitting your question to our ophthalmology forum. I agree with the opinion of the doctor who put the rings on her. The best option at this time would be to perform a crosslinking surgery, since several studies have shown that apart from helping to slow down the progression of ectasia, it can also produce some corneal flattening that would result in better visual acuity with and without correction. Once it had stabilized, and depending on the residual ametropia, performing a corneal refractive surgery (PRK) or posterior chamber phakic lens implant (ICL). The decision would depend on the refractive error to be corrected, but in principle I would be more inclined towards the ICL implant. For any other doubt or question I am at your disposal.
