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 also appears doubled and distorted. Keratocunos does not cause blindness as such, but can lead to disabling vision loss.
Causes of keratocunus
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.

The eye is prepared for the implants placement. To stabilize your eye and ensure proper alignment of the implants, 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 placement. The implants are gently placed. After that, the small opening in the cornea is closed. The procedure is completed. The placement of implants reshape and reinforce your cornea, eliminating some or all of the irregularities caused by keratoconus in order to provide you with improved
