"If you're not fully corrected … you can return after 3 to 6 months and have an additional surgery," Manche says. If this happens, you'll need glasses or contacts to see clearly. There's also a small chance LASIK may not completely correct your vision, especially if you were very nearsighted or farsighted to start. "Frankly, when you compare it to not being able to see, dry eye takes a back seat." "I look like I've been pulling all-nighters a lot." Had she known about the dryness ahead of time, she says she still would have gone ahead with the surgery. Holly Strawbridge, a 68-year-old freelance writer in Fort Lauderdale, FL, has had dry, red eyes since her LASIK procedure about 17 years ago. These symptoms usually peak around 3 months after the surgery and disappear within 6 to 12 months - but not always. The main side effects with LASIK are mild - including dry eye, burning, and itching, which affect 20% to 40% of people who have the procedure. "The idea is to reduce higher-order aberrations, which can cause glare, halos at night, and things like that," Frenkel says. Other advances in technology allow the creation of a customized map of the cornea, which allows for more precise vision correction and better outcomes. Femtosecond lasers have revolutionized the procedure, offering greater safety and precision than a blade. The femtosecond laser, introduced in 2001, uses pulses of light to cut a flap in the cornea. "The results have gotten steadily better and better over time as we've gotten more advanced technology," says Joshua Frenkel, MD, an associate surgeon at Wang Vision Institute in Nashville.
Improvements in the procedure over the years have made LASIK even more effective. "Just to be able to wake up and take a shower and see, and go swimming or snorkeling without any prescription goggles." "It has been a tremendous quality of life improvement," he says. Afterward, he went from needing thick glasses to having better than 20/20 vision.
RED EYE PRO PRICE LICENSE
More than 99% of people end up with 20/40 or better vision, which is clear enough to pass a driver's license exam.ĭaniel Sklar, a 56-year-old strategic consultant from Smyrna, GA, had the procedure done in 1999 to correct severe nearsightedness and astigmatism. More than 90% of people who have LASIK achieve 20/20 vision, meaning they can see from 20 feet away what a person with normal vision should be able to see at that distance, without glasses or contact lenses. There haven't been many high-quality, long-term studies done on the outcomes, but the research that does exist finds the procedure to be safe and effective. have performed more than 19 million of these procedures. In the 20 years since LASIK has been around, doctors in the U.S. LASIK can correct vision problems like nearsightedness, farsightedness, and astigmatism. Then, a laser burns away tissue to reshape the cornea so that light focuses better on the retina in the back of the eye. The surgeon first cuts a thin flap of tissue from the front of the eye. LASIK, which stands for laser-assisted in situ keratomileusis, is a type of refractive surgery. "There are certainly patients who've had some problems, but the vast majority of people do extremely well." LASIK Pros "The FDA has approved it and reaffirmed its safety," he says. Is LASIK safe? Yes, says Edward Manche, MD, a professor of ophthalmology and division chief of Cornea and Refractive Surgery at Stanford University School of Medicine. The FDA responded that the evidence doesn't justify a recall, but it has promised to keep monitoring LASIK safety.
He's asked the agency to pull LASIK from the market. Morris Waxler, PhD, the former FDA official who was part of the original team that approved the procedure, has in recent years claimed the FDA has downplayed the risks. And rarely, people have even lost vision or had long-term pain or other problems. Yet side effects like glare and halos are common after LASIK. Most people who have this surgery end up with 20/20 vision, and the vast majority - more than 95% - say they're happy with the results. Today, doctors perform about 600,000 LASIK procedures in the United States each year. 20, 2019 - LASIK has been FDA-approved to correct vision since 1999.
