So I've learned a bit more since my post, and had a few more consultations. I went to TLC Mississauga, who didn't have an optometrist on site the day I went (why book me for a consult then...), and requested I come back in a week for another consult. In short, they felt like a LASIK Mill, felt very non-personal, and they did not know much about the specifics of my ICL inquiries. The optometrist I spoke to didn't know much about night vision outcomes for PRK and ICL, and their sales Rep at the end flat out said they don't do ICL for someone my age if PRK or Lasik is available. Actually, I spoke to Dr. Tayfour today at NVISION and he said Dr. Dean Smith at TLC Mississauga did ICL once, 10 years ago, and hasn't done any since, after the TLC person said Dr. Smith did their ICL procedures.
I met with Dr. Tayfour today, who as far as my research goes, owns the Lasik clinic in Windsor and was the first in Ontario doing Lasik at all. He's renown for cataract surgery and so it makes sense he does ICL at NVISION. I had a consult with Dr. Tayfour who also did a white-to-white measurement of my eyes today, though I haven't decided yet on ICL vs PRK. The white-to-white involved numbing drops and devices to clamp my eyes open while he placed a measuring decide on my eyes, measuring for ICL's later if I opt for them, which would happen February 2nd, and if I didn't get white-to-white measured today, he'd measure in February and do the surgery in March.
His opinion, which was a little different from my research, was that ICL would give the best outcome of course, but that he would do Lasik instead of PRK on someone with my prescription (roughly -9 each eye), due to issues of corneal scarring with PRK, though this I believe is because he's been in the field so long that his experience with the early generations of PRK probably did have those outcomes, and he hasn't done surgeries on the Schwind Amaris with Smartsurface platform.
More relevant is that my eyes have a keratometey value of 41D, whereas normal eyes are closer to 45. I saw papers and general agreement that going below 35D would have bad visual acuity outcomes. Dr. Tayfour said my post PRK keratometry would be 31, very far below the safe standard for good night vision acuity. I did see estimates of 0.7D of flattening per diopter of visual acuity correction, which instead puts me at around 34-35, but he's probably being conservative.
I'm scheduled to meet Dr. Machat on Monday for another consultation, and if he says I can do PRK, I do it on Dec 20. Dr. Tayfour did recommend I speak to Dr. Machat about night vision concerns, and any other PRK concerns I have. If my corneas were not flat, combined with my high RX, I would definitely have the PRK done, but I want Dr. Machat's opinion on what my night vision outcome will be, and if he recommends ICL, I'll be going that route.
I did mention the deal they have going on with LA fitness and refer a friend discount, I didnt name anyone and May, the advisor, dropped the price from 5100 to 4600 immediately.
