Corneal ulcer, descemetocele

... The cornea, or front of the eye, has three very important functions. It acts as a supportive barrier to keep the internal structures in place within the eye. The cornea allows light to pass into the eye and thus through the lens to the retina at the back of the eye. It also bends the incoming light ...

Although there may also be a slight flattening of the cornea, the most important effect of collagen crosslinking is that it appears to stabilize the corneal curvature and prevent further steepening and bulging of the corneal stroma. There is no significant cha ...

Therefore the ophthalmologists has a special responsibility towards the patients, to be sure that the patient ha ...

The Cornea And Corneal Disease
The Cornea And Corneal Disease

... When the cornea is of normal shape and curvature, it bends, or refracts, light on the retina with precision. However, when the curve of the cornea is irregularly shaped, the cornea bends light imperfectly on the retina. This affects good vision. The refractive process is similar to the way a camera ...
