The cornea is the clear window at the front of the eye that covers the coloured iris and the pupil. Light is focused while passing through the cornea to form a clear image on the retina. The healthy cornea is transparent. If the cornea is abnormal, damaged or diseased, it may become swollen or scarred, resulting in blurred vision or glare. Below are information on some of the conditions that affects the cornea.
- REFRACTIVE ERROR
- DRY EYE
- WATERY EYE
- KERATOCONUS: is a condition affecting the shape of cornea. A healthy eye is more spherical in shape, allowing an image to come into focus clearly. A cornea with Keratoconus bulges outward because it is weak, creating a cone-like shape and consequently, blurred or distorted vision (even with glasses or contact lenses).Keratoconus is a disease that normally affects both eyes, although at differing points of onset and rates of progression. In most people, keratoconus begins during their teenage years and progresses at varying rates until stabilizing in their 30s or 40s. Excessive eye rubbing has also been implicated as a causative factor.Currently treatments for keratoconus include glasses, contact lenses and Collagan Cross-linking and in later stages of the disease a corneal transplant.
OTHER CORNEAL CONDITIONS INCLUDE:
- CORNEAL DYSTROPHIES (Including Fuchs Endothial corneal dystrophy & Lattice Dystophy)
- INJURY SCARRING
- HERPES SIMPLEX VIRUS (SHINGLES)
- CONTACT LENS WEAR
