4 months ago I underwent CK (conductive keratoplasty) to finally correct residual hyperopic astigmatism resulting from conventional lasik and enhancements 7 years ago.
For lasik survivors who were myopic and over-corrected or primary h-lasik pateints like me who ended up with less than acceptable results on the hyperopic side, CK is proving by far to be the least invasive and best choice to resolve refractive errors up to +2 for either sphere or cylinder. I was about +1.25, -1.25 x 15 in both eyes and now have less than +0.5 cylinder with most of the very annoying low light glare and degraded clarity almost gone. Finally getting a solid 20/20 uncorrected is incredible.

CK is fast and virutally painless, with very quick recovery and no risks whatsoever to flaps or making dry eye issues worse. An RF probe is placed at typically 8 spots around the periphery of the cornea that causes the collagen to shrink, pulling down the edges making the cornea less flat. The spots can be moved towards the center a bit closer in the cylinder plane to correct astigmatism.

It is commonly misunderstood that CK effects are only temporary and not permanent. That's probably because it is used mostly for monovision to fix presbyopes with 20/20 distance vision. Advancing presbyopia over time makes additional CK treatments necessary to compensate. But, getting CK to fix hyperopic refractive errors for distance vision IS permanent. While there is a little bit of regression, the correction stabilizes at 2 or 3 months.

I couldn't be more pleased with the results. If you want more info, find a CK specialist in your area. They are usually found at Opthamology clinics and eye surgery centers that do everything, not just lasik. No this is not a commercial for CK. I am a real person who underwent the procedure and offer this information completely on my own volition.

As Glenn has said, CK slowly regresses. I read it regresses at 1/4 diopter per 3 years. Its great to give an emerging presbyope a bit of myopia to keep him out of readers for another 5 years but the CK regresses and the presbyopia becomes too severe. Most hyperopes get lasik because its permanent. CK can be repeated but only once I believe or itll damage your cornea. Dont worry, ive done some reading on epithelial thinning/thickening that can address both myopia(up to -1.5 I heard) and hyperopia(up to -3 I heard)
