Cornea is the outer covering of the eyeball. Protecting structures within the eye is the primary purpose of this coat. In addition to acting as a structural barrier, the cornea also protects the eye from infection. Combined with the tear film, it provides a proper anterior refractive surface for the eye. The cornea contributes two-thirds of the eye's refractive power.
Common symptoms of corneal ulcer are:

With immediate treatment, most ulcers can be treated without vision loss. But if the infection is left untreated or is too severe, ulcers can permanently harm your eyes.
MS-39 is the most advanced device for the analysis of the anterior segment of the eye. MS-39 combines Placido disk corneal topography, with high resolution OCT-based anterior segment tomography.
Cross-linking the cornea (also called C3-R) is another option. There is no need for invasive surgery with this new treatment. It increases the cornea's strength. The bulge may not be fixed, but it can be stopped from getting worse.
Latest treatment for keratoconus is topo-guided C3R. Under this treatment, the cone shaped cornea is smoothened with the help of excimer laser and then C3R (collagen crosslinking) is done to strengthen the cornea. This procedure not only stops bulges from growing but also provides functional vision.
A pterygium is a growth of the conjunctiva or mucous membrane that covers the white part of your eye over the cornea. The cornea is the clear front covering of the eye. This benign or noncancerous growth is often shaped like a wedge. A pterygium usually doesn’t cause problems or require treatment, but it can be removed if it interferes with your vision.
A pterygium doesn’t always cause symptoms. When it does, the symptoms are usually mild. Common symptoms include redness, blurred vision, and eye irritation. You might also feel a burning sensation or itchiness. If a pterygium grows large enough to cover your cornea, it can interfere with your vision. Thick or larger pterygium can also cause you to feel like you have a foreign object in your eye. You might not be able to continue wearing contact lenses when you have a pterygium due to discomfort.
The results will depend on what damaged your cornea. Most people will have at least some vision improvement. It is important that you come for follow-ups to make sure that your eye is healing properly. In most cases, the surgery is very successful.
One must get a corneal transplant if the cornea may be severely damaged by:
