Communication, Information Vital to Minimizing LASIK Risk

Not everyone is a candidate for LASIK, and doctors say it's important for prospective patients to understand that. People with vision that continues to get worse, extremely poor vision, certain characteristics of the cornea and some diseases may not be suitable candidates for the procedure.

"Doctors need to take time with a patient and get all the information they need," Asbell said. "Doctors also need to learn what the patient's expectations are. If a person wants 20/15 vision, they may not be the best candidate."

Experts also say there are still things about LASIK that they just don't know.

"It's very hard to quantify these side effects, such as determining how to measure how bad things like glare and halos are," Asbell said. "It's hard to pin down risk factors that differentiate the people who have problems from the ones that don't so we can try to learn more."

"There are many things we still don't know about the cornea, such as physiology and variability in structure, so we don't know why some patients bounce back and others don't," Cykiert said.

Cykiert also said that the thousands of people who have problems have a legitimate reason to complain to the FDA, and that information they provide can be helpful for everybody.

"That's how we're going to make the procedure safer and better," he said.

And that's also how there may eventually be more people like Andy Ng, who has no complaints about his LASIK experience.

"The procedure is one of the best things out there for the eyes," he said.
