VISIAN ICLS: The Final Answer?

After mulling everything over for the last 6 months and almost pulling the plug on the whole idea Dr. Rabinowitz called me up recently to let me know that a new Visian ICL was now available. I've yet to verify all his claims but if they all check out then I've made my decision. I'll have the newer Visian ICLs implanted!
So why those and not anything else?
Well here's an overview of the most important points that lead to my decision:

LASIK: NEVER!
Way too many risks and completely irreversible. Potential night vision problems, post-op permanent dry eye, lower quality vision since the laser shaped area isn't perfectly smooth like the natural eye, permanent destabilization and thinning of the cornea. No way.

INTACS: nope.
Not precise enough (1/2 diopter steps instead of 1/4 diopters), limited availability, insufficient range of prescription (max -3 diopters myopia), optically correct zone is likely too small

PHAKIC IOLS:

VERISYSE PIOLs: no
large cut into cornea likely to increase astigmatism, optically corrected area potentially too small, not available in my prescription (minimum prescription is -5 diopters of myopia). Endothelial cell loss.

VISIAN ICLs: yes
small incisions not likely to increase astigmatism, collamer material supposedly has excellent compatibility with body tissues, designed to repel protein deposits, optically corrected area at 5.9mm is large enough, lenses are completely invisible from the outside. Risk of initial endothelial cell loss. Risk of cataract formation greatly reduced with improved vaulting of new version of the lenses. Lenses can be removed if cataract formation is detected. Worst case scenario: natural lens replacement required due to fully formed cataract. Regular checkups are probably a good idea to catch any developing problems early on. It's still a mixed bag and there's no perfect solution but this seems the most reasonable choice to me. The one thing I'm most worried about is actually optical effects from stray light entering the eye through the tiny cuts created during the iridotomy. But it seems that only relatively few people experience this effect.

Well, there you go.

This wraps up the background posts leading up to my current situation. From here on out I'll simply post about my experiences with my doctor, the procedure itself and life with my new set of eyes.

Stay tuned!
