<h3>What is an uneven cornea?</h3>
- Astigmatism occurs when light enters the retina unevenly due to the irregular shape of the cornea.

- Astigmatism can be inherited or developed later in life. An irregular corneal surface is common and can be caused by a variety of factors, including genetic inheritance, injury, disease, or natural occurrences.
- The epithelium, bowman's layer, stroma, descemets membrane, and endothelium, which is the innermost layer, comprise the cornea.
- A treatment called cornea collagen crosslinking may stop the condition from getting worse. Or your doctor could implant a ring called an Intacs under the cornea's surface to flatten the cone shape and improve vision.
