CORNEAL ECTASIA

WHAT IS CORNEAL ECTASIA?

Corneal ectasia is a complication resulting from LASIK surgery. This condition involves a thinning and bulging of the cornea. Frequently corneal ectasia is characterized by an increase in the patients’ myopia and astigmatism. Corneal ectasia can occur immediately following LASIK surgery or months to years later.

WHAT ARE THE SYMPTOMS OF CORNEAL ECTASIA?

Symptoms of corneal ectasia include:

  -Frequent changes in the patient’s eyeglasses or contact lens prescription
  -Progressive myopia and levels of astigmatism
  -A decrease in the patient’s best corrected visual acuity
  -Halos, glare, shadows and ghost images
  -Dry and/or red eyes 
  -Ocular pain and headaches
  -Depression

HOW IS CORNEAL ECTASIA TREATED?

Many corneal surgeons will attempt to improve this condition using Collagen Cross Linking and/or surgically implanting intra-stromal plastic rings (intacs) to make the corneal surface more regular. It has been my experience that the vision and ocular complications created by LASIK induced corneal ectasia is best treated in a non-invasive manner. A well designed and properly fit scleral lens can restore quality vision and ocular comfort to patients  suffering from LASIK induced corneal ectasia. The reason for this is that only a scleral lens can replace the cornea as an optical surface. It’s like getting a new cornea. A scleral lens will vault over the compromised cornea and come to rest on the white portion of the eye (the sclera). The space between the back surface of the scleral lens and the front surface of the irritated, distorted cornea is filled with sterile, unpreserved saline solution. In other words, the front surface of the eye is always in a liquid environment. Vision and comfort is almost always excellent.
