Cornea is an important part of the eye required for clear vision. Even microscopic changes in cornea can cause moderate to severe reduction in vision. These changes may be the result of various pathological processes, for instance infection, injury, metabolic disorders and degenerative changes. Depending on the cause, medical and surgical treatments including corneal transplantation and keratoprosthesis surgeries are used to achieve optimal vision. But we should probably expect much more. According to Dr. Stephen [...]

Glaucoma causes damage to optic nerve resulting into irreversible loss of vision. There are multiple factors involved but high intraocular pressure (IOP) plays an important role in the process of damage. High IOP is also a factor around which a whole range of treatment modalities revolve. Glaucoma drainage devices of various types are the latest addition to the traditional treatment methods for glaucoma. Known as a “glaucoma drainage device,” “tube shunt,” “glaucoma valve,” or “Seton,” [...]
After LASIK procedure, the vision usually improves to a satisfactory level but in some people, it is not what they desired. Additionally, in some other patients, the vision deteriorates after some time. In such cases, LASIK can be repeated to further improve the vision. Lasik Enhancement or touch up is a procedure following the original lasik procedure with the goal of further sharpening the vision. This procedure is usually performed when the original Lasik surgery [...]
Myopia is a condition in which a person cannot see distant objects clearly. In children, it is caused by focusing on near objects like books and electronic devices for long periods. Prolonged near work causes the spasm of the focusing muscle or ciliary muscle in the eye. This is also associated with irreversible elongation of the eye and hence myopia. Myopia cannot be reversed or cured. But there are some steps which parents can take [...]
Pterygium is a degenerative fibrovascular growth which originates from the conjunctiva (the membrane on the white part of the eye) and encroaches the cornea (the transparent tissue at the front of the eye). In the early stages, it can cause astigmatism. As it grows further, it can even cause blindness if not treated timely. Surgery is the only option to get rid of pterygium. It is known for recurrence if the surgical technique is not good. [...]
