I had PRK with Optimax in Birmingham in 1999 on one eye but didn't go back for the second since it was so painful for two days afterwards. I was -3.75 pre-op and am now +1.25. I guess that means I got over-lasered! The surgeon didn't inspire me with confidence at the time, and kept on having to restart the laser when my eye moved out of position. I was meant to be looking at a red spot, however I couldn't see if after a while due to blurring. I imagine they use tracking lasers nowadays. I am now considering LASIK for the other eye, but not at Optimax. Optimax are cheap compared to others, so think about it.
