Keratoconus is a disease that results in thinning of the central zone of the cornea, the front surface of the eye. During further observation, it is found that the normal eye pressure causes the round shape of the cornea to distort and an irregular cone-like bulge develops which results in significant visual impairment.
The quality of vision seems poor which also occurs primarily from irregular astigmatism and distortion that results in the image focusing at multiple points instead of a single point focus. It is also observed that the image is ghosted, flared and appears doubled & distorted. Keratoconus does not cause blindness as such but can lead to disabling vision loss.
Causes of keratoconus
The cause of keratoconus remains unknown, although recent research indicates that it may result from a combination of genetic and environmental factors. Some cases of keratoconus have a hereditary component and studies indicate that about 10 to 20% of keratoconus patients have affected relatives. It is observed that if there is no evidence of keratoconus in successive generations of a family, there is less than a 1 in 10 chance of the children of a person with keratoconus also having the condition.
Prior to the Procedure
It is common to experience anxiety before any surgery, but the actual procedure is far less invasive than many other surgical procedures of the eye. Its success rate is high compared to the other.
The experts performing the procedure are mostly corneal surgeons that have expertise with keratoconus. Each surgeon has undergone rigorous training programs and years of experience in treating patients with keratoconus.
The patient’s examination includes a variety of standard ophthalmic tests for keratoconus, as well as general medical tests and a review of their specific medical history is done before the surgery.
Anesthetic drops are used to numb the eye, which is held open throughout the procedure to prevent blinking. A single, small incision is made in the surface of the cornea. The eye is then prepared for the placement of the implant.
To stabilize the eye and ensure proper alignment of the implants, the centering guide is placed on the surface of the eye. During this time, inner layers of the cornea are gently separated in a narrow circular area to allow for placement. The implants are gently placed. After that, the small opening in the cornea is closed.
The procedure is completed. The placement of implants reshapes and reinforces the cornea, eliminating some or all of the irregularities caused by keratoconus in order to provide with improved and clear vision.
Post surgery procedure
A patient is expected to follow-up and frequent visits are required for a certain period after the surgery 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 the patient with a clear vision.
As with any surgical procedure, some risks are involved, including infection. Some patients experience visual symptoms which include difficulty with night vision, glare, halos, blurry and fluctuating vision.
