F.A.Q
WHAT IS CORNEAL TRANSPLANT?
WHAT IS CORNEAL TRANSPLANT?
The cornea is a clear layer of the tissue covering the front of the eye, similar to a watch crystal. Its purpose is to refract or bend light rays as they enter the eye, allowing them to focus on the retina. In cases where the cornea has become clouded as a result of disease, swelling, infection, etc, the patient may lose vision as the light rays are no longer able to enter the eye. The corneal transplant is removing the central tissue of the clouded cornea and replacing it with a healthy and transparent replica of donor's tissue, to restore functional vision. The general misconception is that all patients who lost vision can restore vision with eye transplant, but it is wrong. The current eye donation is actually corneal tissue donation, just for the corneal transplant.
WHAT IS LASER VISION CORRECTION?
WHAT IS LASER VISION CORRECTION?
It is an outpatient treatment that uses a cool beam of light to gently reshape the surface of the eye
- the cornea
- thereby improving vision.
The light gently pulses to remove a microscopic amount of tissue, flattening the curvature of the cornea, allowing images to be more sharply focused on the retina.
The FDA has approved treating nearsightedness, farsightedness, and astigmatism with the VISX laser.
This approval means that the FDA has recognized that laser vision correction with VISX is a safe and effective procedure.
WHAT ARE THE BENEFITS OF LASER VISION CORRECTION?
WHAT ARE THE BENEFITS OF LASER VISION CORRECTION?
Laser vision correction for nearsightedness, farsightedness, and astigmatism is designed to be a onetime treatment that should reduce the condition overall, while also reducing or eliminating your dependence on glasses and contact lenses.
WHAT ARE THE DIFFERENCES BETWEEN LASIK, PRK, AND RK?
WHAT ARE THE DIFFERENCES BETWEEN LASIK, PRK, AND RK?
You may have heard about PRK, which stands for Photorefractive Keratectomy, the medical name for the laser procedure.
PRK and LASIK (Laser in-situ Keratomileusis) both utilize the VISX Laser System to remove corneal tissue in order to flatten the cornea.
In the PRK procedure, the laser works on the surface of the cornea.
With LASIK, the surgeon first creates a flap on the cornea and then uses the laser for treatment below the corneal surface.
RK (Radial Keratotomy) is a non-laser procedure where the surgeon uses a knife to make a series of radial cuts into the cornea.
These cuts are intended to produce a bulging effect in order to flatten the corneal surface.
While PRK has been approved by the FDA, your doctor can also perform LASIK when they believe it is beneficial to the patient.
IS LASER VISION CORRECTION SAFE?
IS LASER VISION CORRECTION SAFE?
Yes. Over one million patients worldwide have had this treatment performed on them successfully.
The FDA has recognized laser vision correction for nearsightedness, farsightedness, and astigmatism, and found the treatment safe and effective for eligible patients.
DOES LASER VISION CORRECTION HURT?
DOES LASER VISION CORRECTION HURT?
No, the treatment itself is painless.
Some patients may experience discomfort for one to three days after treatment.
Many patients compare this to a sensation of sand in the eye.
Your doctor can prescribe pain medication to alleviate any discomfort during the recovery.
WHAT HAPPENS BEFORE THE TREATMENT?
WHAT HAPPENS BEFORE THE TREATMENT?
Your doctor will conduct a thorough examination to determine whether your eyes are healthy and suitable for the laser procedure.
Your eye will be photographed and a computerized map made, called corneal topography.
This will assess the shape of your cornea, and is one of the many diagnostic tests the doctor uses to help ensure precise results.
