Best and Worse Case:

When each laser gets approved in the US it has to pass through the FDA. Each laser manufacturer is required to sponsor a study with hundreds of patients, several surgeons, all using the same technique and follow those patients for years. The FDA closely examines and audits the charts and results before approval. All the lasers are held to the same standard so it really is an "apples to apples" comparison. While "Doctor Smith" may say his results are better than "Doctor Jones", there really is no proof like a formal FDA study. Take a look at the FDA website for yourself. The graph above shows the results for patients with up to 7 units of myopia and 4 of astigmatism, which includes most of us by far. For example, with the B&L laser, one would have nearly a 90% chance of 20/20 and nearly a 100% chance of 20/40. With our new Wavelight laser, 93.4% of a similar group saw 20/20 or better without glasses after surgery.
