LASIK eye surgery has provided numerous options for people suffering from vision problems such as myopia (nearsightedness), hyperopia (farsightedness), and even astigmatism. One aspect of LASIK surgery that has made it such an innovative and effective procedure is the LASIK flap.
Creating the LASIK Flap
The first step of LASIK eye surgery is to partially detach a very thin layer of tissue from the cornea. This layer of tissue remains attached to the cornea on one side, creating a “flap.” Dr. Kelly then uses a cool laser to alter the shape of the cornea beneath the flap. Changing the shape of the cornea will correct whatever vision problem is being treated.
After the shape of the corneal tissue beneath the flap has been properly altered, the flap of tissue is set back into place. This flap serves as a protective covering for the area of the eye that has been operated on, and thus facilitates rapid healing. In fact, with the use of a LASIK flap, the corneal tissue can be as much as ninety percent healed within twenty-four hours.
Advantages of the LASIK Flap
Before LASIK surgery techniques were developed, doctors used photorefractive keratectomy, or PRK, to correct vision. Known as an ablative procedure, PRK removes small pieces of tissue from the surface of the cornea. Though this procedure provides effective vision correction, and is still used in some cases when the cornea is too thin or misshapen to work well with a LASIK procedure, it takes longer to heal.
In order to determine if LASIK will work well to correct your vision, you should consult with a LASIK surgeon such as Dr. James Kelly. Dr. Kelly, who specializes in New York City area LASIK surgery, will evaluate your vision, the shape of your cornea, your overall health, and other factors. He will then provide a suggested course of treatment and help you decide if LASIK is right for you.
If you suffer from nearsightedness, farsightedness or astigmatism, LASIK might be an excellent option to improve your eyesight. For more information about how LASIK can help you, please contact the New York City LASIK specialists at Kelly Laser Center to schedule a LASIK consultation.
