Laser Eye CareTech for Correcting Vision
Laser vision correction is a process of using FDA-approved laser technology to correct your vision and reduce or eliminate your need for glasses or contacts. It’s a multi-step process designed to alter the shape of your cornea to help your eyes focus better. For many people, it’s a procedure that has dramatically improved their sight and made their lives easier.
Why Laser Eye Care Works
Correcting vision issues with a laser procedure is increasingly popular. Essentially, the procedure reshapes the surface of your cornea to better reflect light into your eye. This works because of how you see. Sight is the result of light entering your eye and getting refracted and focused by your cornea (which is like a clear window in front of your iris) as well as the lens inside your eye. Together, they direct the light to your retina, which sits on the back interior surface of your eyeball. The nerves in your retina then send the information to your brain, which interprets what you see.
However, the length of your eyeball and the shape of your cornea can change, which impacts how light strikes your retina. Ultimately, this is why you need glasses or contacts—your eyes aren’t able to refract a clear image onto your retina. Laser eye surgery such as LASIK (laser in-situ keratomileusis) or PRK (photorefractive keratectomy) reshapes the curvature of the cornea to allow your eyes to focus better without glasses or contacts. For many people, this can dramatically improve vision and lifestyle.
What to Expect from Laser Eye Surgery
In LASIK, a thin flap is created in the front layers of the cornea. The flap is then lifted up, allowing the excimer laser to reshape the underlying tissue. The flap is then carefully repositioned on the cornea where it remains held in place. The recovery is quick and comfortable, with a brief course of medication eye drops to prevent infection or inflammation.
In PRK, the surface layer of the cornea (the epithelium) is carefully brushed away, allowing the excimer laser to reshape the underlying tissue. A “bandage” contact lens is placed on top of the cornea, allowing the epithelium to regrow. Recovery for this procedure takes a bit longer, and you might feel a mild grittiness and light sensitivity. However, PRK is a good choice for patients with thinner corneas and higher vision corrections.
Am I a Candidate for LASIK?
Unfortunately, not everyone can have LASIK or PRK. Factors like the thickness of your cornea and the vision correction you need can affect whether or not these procedures are safe for you. The best way to determine if you are a good candidate for LASIK or PRK is to receive a screening exam. You will undergo several tests to measure your cornea, as well as your glasses or contact lens prescription. Our physicians will then review the test results and determine if laser eye care safe for you.
Laser eye care is a valuable tool that can help dramatically improve your sight, offering you greater independence.
