How does LASIK surgery work? LASIK stands for Laser Assisted In Situ Keratomileulis. It is an eye surgery using the VISX laser to reshape the cornea. The purpose of the eye surgery is to change the surface of the cornea allowing it to refocus light onto the retina so you can see clearly. You may consider LASIK if you would like to be less dependent on glasses.
Can I Have Lasik?
LASIK can treat certain amounts of nearsightedness (myopia), farsightedness (hyperopia) and astigmatism. There is often a misconception that LASIK cannot treat astigmatism. Dr. Stanley Grandon and I can perform a comprehensive LASIK evaluation to determine if you are a candidate for LASIK. We need to make sure your eyes are healthy enough to have the surgery and that your glasses prescription is in the ranges that LASIK can be safely performed. If you already require reading glasses, we can discuss options with you as well.
How Does Lasik Surgery Work?
The cornea is extremely powerful in focusing light. It is responsible for 2/3 of the focusing power of the eye. Therefore reshaping the surface has tremendous effects on focusing without the need for glasses.
The laser removes microscopic amounts of tissue on the cornea so that the cornea focuses light onto the retina. If you are nearsighted (myopic) the cornea will need to be made flatter. If you are farsighted (hyperopic), the cornea will need to be made steeper, and if you have astigmatism the cornea will need to be made less irregular.
Lasik is a pain free outpatient procedure. Dr. Stanley Grandon and I will focus the laser onto your eye and perform the procedure in about 5 minutes. After the procedure, your eye will likely feel scratchy and the vision may be blurry for a few days. You will need someone to drive you home and then you will be seen in our office the next day.
A full eye examination starts with the doctor checking your vision. Then, the doctor will perform a refraction. This is when the eye doctor tries to see how good you can see with eyeglasses. The eye doctor wants to know how good you can see with a pair of eyeglasses. An eyeglasses examination may often end now.
Comprehensive Eye Exam
A comprehensive eye examination includes many other aspects to check the health of your eyes. Diseases of the eye such as glaucoma, cataracts and macular degeneration (ARMD) will not be detected on a glasses examination.
A comprehensive eye examination includes a eye pressure check to assess for glaucoma, a slit lamp examination as well as dilation of the pupils. Dilating the pupils allows the doctor to again check for glaucoma, to check for cataracts, macular degeneration (ARMD) as well as many other diseases of the eye. Many cases of glaucoma can be missed if the pupils are not dilated. An eye examination can take an hour or more.
It is especially important to have a dilated eye examination if you have diabetes or a family history of eye diseases. Many causes of preventable blindness have no symptoms, especially at the early stages. Depending on your age, recommendations for complete eye examinations vary, but many of our patients are seen on an annual basis. We all want to see for the rest of our life!
Board Certified Ophthalmologist
A board certified ophthalmologist will typically perform a comprehensive eye examination to make sure your eyes are healthy. If any diseases of the eye are suspected, they may decide that further in depth testing is indicated. This testing can help the doctor determine the severity of the disease and if any treatments are indicated. The doctor will let you know how often follow up evaluations are indicated.
