Participated in PROWL and unhappy with your LASIK? Contact Me at RogerDavis@gmail.com

Results from PROWL-1 and PROWL-2 have been released. These studies were intended to examine the safety and efficacy of LASIK eye surgery. The numbers were quite discouraging. Up to 4% of patients reported being dissatisfied with their LASIK outcome. Generalizing from these results, the raw numbers of patients who feel themselves to be visually impaired post-LASIK exceeds the total number of Keratoconus patients in the USA. In fact, the rate of visual impairment among patients having LASIK exceeds that of many natural diseases and conditions of the eye in the general population. Consider: If 20 million people have had LASIK in the USA, that leaves 800,000 people visually impaired. Yet, the mandate of the FDA is to protect the public health, a contradiction. Sadly, the 4% was obtained with few adverse events and recent LASIK technology, meaning that these bad outcomes have no identifiable cause other than LASIK itself.

If you participated in PROWL-1 or PROWL-2 with a bad outcome, I'll be happy to illustrate your vision. Quantitative and qualitative data are always viewed as complementary in solving important scientific problems. The world needs to know how you see.

Visual Snow Simulator: Patients who complain of Visual Snow literally see what resembles "television snow," that is, specs or particles that blink on and off in their vision. Unfortunately, no one knows what causes visual snow, but given its strong resemblance to "noise in the system," it could be that neural activity in the visual cortex is simply operating at too high a baseline, with many neurons firing more often than they should. At the level of perception, this would be seen as white specks in the visual field.
