Unfortunately, when our cornea is severely damaged or misshapen, then a cornea transplant may be recommended. Glasses and contact lenses also serve to improve vision. Patients can choose refractive surgeries like LASIK which alter the shape of our cornea enabling light to focus precisely on the retina. If a patient has astigmatism or an irregularly shaped cornea, light focuses in multiple places, and vision is always blurred. If the light focuses in front of or behind the retina, we are nearsighted or farsighted respectively. If it focuses light directly on the retina, we see clearly. How well we see is dependent on the shape of the cornea and exactly where the light touches the retina. Along with our natural crystalline lens, it helps to focus light precisely onto the retina for clear vision. The cornea is the clear front surface of our eye and it is the window to the retina.
