What is LASIK?

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?How does Lasik surgery work?

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.

Lasik and Dry Eyes

What is Lasik

Lasek has fewer complications of dry eye than Lasik.

Lasik (laser-assisted in situ keratomileusis) is an eye surgery that reshapes the cornea in order to reduce or eliminate the need for glasses.  Epi Lasek is meant to achieve the same outcome as Lasik.  There is no stromal corneal flap with Epi Lasek which eliminates some potential complications.   Both Lasik and Epi Lasek can provide excellent refractive outcomes.Lasik | Epi Lasek | Dry eyes| Alaina Kronenberg MD

Lasik and Dry Eyes

Dry eyes is the most common complication from refractive eye surgery.  Dry eyes can be due to either inadequate tear production or excessive evaporation of the tears.  There can be inflammation of the ocular surface.

It often occurs in the immediate post operative period and it is usually transient and often resolves during the first year after the surgery.  It is important for your ophthalmologist to perform a detailed comprehensive eye examination prior to your surgery to diagnose dry eyes or risk factors for dry eyes.

Dry Eyes

Symptoms of dry eyes can include burning, stinging, a foreign body sensation, fluctuating or blurry vision and a gritty sensation in the eyes.  Dry eyes can range from mild to severe.  Dr. Stanley Grandon, Dr, Cindy Wang and I will treat your dry eyes with a combination of over the counter and prescription medications depending on the severity of the condition.

Lasik and Dry Eye

When traditional Lasik is performed, a flap is cut in the cornea.  This causes some of the corneal nerves to also be cut.  This can cause the sensation of the cornea to be reduced.  You may not sense the need for more lubrication and therefore less tears are made by the glands around the eyes.

Dry eyes after refractive surgery can not only affect the comfort of the eye but also the quality of the vision.  If you suffer from dry eyes after your surgery, it is important that we treat it promptly.

Epi Lasek

When Dr. Stanley Grandon and I perform Epi Lasek, no stromal corneal flap is cut.  Therefore the corneal nerves are not disrupted.  This may decrease the chances you will develop dry eyes after your surgery.  You may be a better candidate for Epi Lasek if you suffer from dry eyes before your surgery.
