The reason I posted that info from the Visx thread is because it reassures me that we do not need to concern ourselves a lot about the probable recomendation by the FDA's Ophthalmic Panel for approval of PRK and LASIK for hyperopia on the 27th of this month.

When I found out that this panel would address the procedure, I became concerned with the timing of the PRK approval with respect to the period of time it will take SNRS to get approval. The Visx product is already in the market, already has an installed base, already has customers doing a huge amount of consumer advertising, and having a year headstart (hopefully much less) could greatly harm a better mousetrap.

I like to describe LASIK as slicing the front of the eye nearly off, blast away part of the cornea you look through, and then try to bandage the wound with what remains of the sliced off piece. This contrasted to gentle warming of corneal collegen to do the same procedure. I like to compare the two this way because I am a little worried about the market having enough time to start accepting LASIK for hyperopia. I would hate to see LTK get approval and have the market say "so what!".

My whole point in my questions at the shareholder's meeting which were answered by Dr. MacFarland was to get reassurances beyond the obvious "It is a much better procedure." What MacFarland said was that the complication rate is much too high for hyperopia and the procedure will not be performed by ophthalmologists for that reason alone. He said that they have been able to perform the procedure for a long time in Europe and that it is rarely preformed any more because of these problems.

The posting by <admr> who signed his post Andrew Richman, M.D. on the Visx thread simply was another source of confirmation of MacFarland's words.

I have spent enough time reading the patents that Sunrise holds to know that there will not be any thermal LTK competitors popping up so I tend to look now at other kinds of competition. These being PRK, LASIK, and the intrastromal ring.

I hope that any other shareholder's that have had these same concerns feel a little more at ease like I do at hearing these words from clinicians.
