CORNEA SURGERY

 |
A cornea transplant, also known as a corneal graft or penetrating keratoplasty, is a surgical procedure where a damaged or diseased cornea is replaced by donated corneal tissue which has been removed from a recently deceased individual having no known diseases which might affect the viability of the donated tissue. The cornea is the clear part of the eye in front of the iris and pupil. Keratoconus is the disease that creates the thinning of the cornea. Normal outward pressure within the eye causes the cornea to progressively bulge into a cone-like shape. The change in the cornea's shape can have a dramatic impact on one's vision. In more severe cases, normal everyday activities such as driving and reading can be difficult to perform.
Intacs
Intacs is a new procedure performed on patients with a disease known as Keratocomis. In the past the only surgical option was a cornea transplant, which is a very invasive operation. The Intacs procedure was designed to stabvilize the cornea, improve vision and potentially eliminate the need for a cornea transplant.
The Procedure for Intacs
Anesthetic drops are used to numb the eye, which is held open throughout the procedure to prevent blinking.
Step 1: A single, small incision is made in the surface of the cornea.
Step 2: The eye is prepared for Intacs placement.
To stabilize your eye and ensure proper alignment of the Intacs inserts, the centering guide is placed on the surface of your eye. During this time, inner layers of the cornea are gently separated in a narrow circular area to allow for Intacs placement.
Step 3: The Intacs inserts are gently placed.
After the second Intacs insert is placed, the small opening in the cornea is closed.
Step 4: The procedure is completed.
The placement of Intacs inserts remodel and reinforce your cornea, eliminating some or all of the irregularities caused by keratoconus in order to provide you with improved vision.
Follow-up visits will be required to monitor the healing process and evaluate the visual benefits of the procedure. Even after a successful procedure, glasses or contacts still may be required to provide you with good vision.
Pterygium
Pterygium is a raised wedge-shaped growth of the conjunctiva. It is most common among those who live in tropical climates or spend a lot of time in the sun. Symptoms may include irritation, redness, and tearing. Pterygiums are nourished by tiny capillaries that supply blood to the tissue. For some, the growth remains dormant; however, in other cases it grows over the central cornea and affects the vision. As the pterygium develops, it may alter the shape of the cornea, causing astigmatism. If the pterygium invades the central cornea, it is removed surgically
