What is LASIK laser eye Surgery
For anyone who wears glasses or contact lenses, the chance to see more clearly with your own eyes is an exciting idea.
The goal of LASIK is to reduce or eliminate refractive errors including nearsightedness, farsightedness and astigmatism, so you can rely less on glasses and contacts.
LASIK laser eye surgery has the highest patient satisfaction rate of any elective surgery: 95.4%, according to a 10-year survey of scientific studies from around the world. And new advances in technology now deliver better outcomes than ever.
The majority of patients enjoy 20/20 vision or better after laser eye surgery. Nearly all patients achieve 20/40 or better, which is fully functional and good enough to drive legally in most states without corrective lenses.
Keep in mind-if you’ve developed symptoms of farsightedness later in life (after about age 40), you may have presbyopia rather than farsightedness. LASIK may still be able to help, but you should also consider other presbyopia surgeries.
How LASIK laser eye Surgery works
LASIK, which stands for laser in-situ keratomileusis, uses a highly specialized laser-called an excimer laser-to reshape the cornea and give you focused vision.
An excimer laser emits pulses of concentrated, cool, invisible ultraviolet light. When targeted to specific spots on the cornea, it gently and precisely reshapes the cornea by removing extremely tiny amounts of tissue (25 100,000ths of a millimeter at a time), without disturbing other tissue.
There are a number of types of LASIK and different laser eye surgery techniques (see other surgeries) to choose from. Your surgeon will carefully evaluate your eyes, health history and refractive error, as well as your age, lifestyle and career considerations to help you decide if LASIK is right for you and which type is best for you.
Is LASIK right for you?
People interested in laser eye surgery often say:
Glasses and contacts are uncomfortable, expensive and easy to lose or break.
I want to get out there and play sports, travel and live an active life-without depending on glasses or contacts.
I want to be able to read the alarm clock in the morning.
I’d feel safer about everything from swimming in the ocean to finding my way at night if I didn’t need to wear glasses or contacts.
Taking care of my contact lenses is too time-consuming.
I would be able to work more effectively if I could see better through my own eyes.
I’d feel better about my appearance if I didn’t have to wear glasses.
These are the main reasons people get LASIK. They’re also the same reasons so many people are satisfied with the results.
If you are nearsighted, farsighted or astigmatic, LASIK may be able to help. If you’re over age 40 and also have presbyopia or cataracts, other surgical options may be even better for you. Learn more about presbyopia surgery and cataract surgery.
If you’re under age 40 and are nearsighted, farsighted or astigmatic, learn more about the types of LASIK surgery to see which one may be right for you.
