Professional Cornea Surgery in Las Vegas, NV
The cornea is the clear covering on the front of the eye, which refracts light rays that focus on the retina in the back of the eye. A certain shape or curvature is required for light to focus exactly on the retina, rather than in front of or behind it. An improperly curved cornea may be corrected non-invasively or through cornea surgery in Las Vegas, NV, to reduce or eliminate the need for eyeglasses and contacts. A thorough exam and consultation at Siems LASIK & Eye Centers are necessary before a treatment decision can be made.
Corneal transplantation is recommended when the cornea’s curvature is too steep or flat to be treated with other methods, or when injury, infection, or disease has caused extensive damage. Common problems that require transplantation are:
- Dry Eyes
- Recurrent Erosion
- Corneal Ulceration
- Herpes Simplex Keratopathy
- Pseudophakic Corneal Decompensation
- Corneal Dystrophies
- External Tumors
- Eye Infections
- Traumatic Injury
- Ocular Surface Diseases
- Chemical Burn
Transplantation involves replacing the damaged cornea with a healthy one from a donor, usually through an eye bank. This is a low-risk procedure, as it’s the most common type of transplant surgery with the highest success rate.
During the procedure, a circular incision is made in the cornea. A disc of tissue is removed and replaced with healthy tissue; these discs may be thin (lamellar keratoplasty) or as deep as the entire cornea (penetrating keratoplasty, the technique used in almost all transplants). Local or general anesthesia may be used. The entire procedure takes only 30-90 minutes.
