Ajwani Eye Hospital has 35 years’ Well trained corneal surgeons provide “cutting edge” treatment for most corneal disorders.
1) Corneal ulcer
When an inflammatory process involves the cornea, the condition is termed keratitis. An ulcer developing in the cornea is usually accompanied by keratitis, but more importantly involves a loss of the covering empitheliu, many atime with the tissue underneath it as well , it is relatively common condition as the cornea is exposed to the environment corneal ulcers tend to be more common in the topical countries, especially where agriculture is in abundance, as in india. they may be a cause of great visual morbidity and economic loss to the individual.

2) Causes
Infective corneal ulcers are, by far, the commonest causes of ulcers in the tropics. Among these, bacterial infection are quite frequently encountered. Predisposing fatcors like trauma may lead to bacterial corneal ulcers, which tend to severer than other infections. Fungal infection may occur, especially, after injuries with vegetative matter like leaves or twigs. Viral corneal ulcer with the herpes simplex virus are very common.
3) Symptoms
Patients of corneal ulcers are very distressed and disturbed with their condition. There is a lot of pain due to exposure of naked nerve endings. Redness and watering are marked. The patient is intolerant to bright light. There may be other symptoms as well, especially if the infection is serve, like headache, malaise and fever. symptoms are more marked in case of bacterial ulcers and quieter with fungal ulcers.
5) Consequences
Corneal ulcers are potentially serious and even sight threatening conditions.Consultation with an ophthalmologist should never delayed if the above symptoms are present. some, very superficial ulcers may heal fast without any sequelae. But may are associated with complications. Infection may spread leading to corneal thinning and perforation. It may spread to the interior of the eye leading to endophthalmitis. Scarring may occur in the cornea, as occurs in other parts of body. This scar tissue tends to be opaque compared to the normal cornea, thereby, obstructing light and causing blurred or diminished vision.
5) Treatment
After a proper examination under a slit-lamp and other tests that may sometimes be necessary, the type of infection is recognized and a line of therapy selected. Bacterial ulcers are treated with topical fortified antibiotic preparations. These are not available commercially and have to be prepared from injectable forms of the same antibiotic. Fungal ulcers require anti-fungal eye drops. Herpetic ulcer are trated with topical anti-virals like acyclovir. Supportive therapy for the dilatation of the pupil and relaxation of the ciliary muscle is usually added. Oral medication in the form of pain-killers of anti-fungals may be required. Occasionally required modallities that may be added include bandage contact lenses, conjunctival flps, scraping of the ulcer, etc. A corneal transplant may be essential if the ulcer has healed leaving a large scar that obstructs vision. It is important for patients to realize that steroids and anesthetic drops should be avoided in case of corneal ulcers. They delay healing and may actually make the condition worse. They should only be used after consultation with an ophthalmologist.
Pterygium, also known as “surfer’s eye” is a growth of tissue on the conjunctiva that can invade the cornea causing red eyes, itchy, burning sensation, and in some cases, can affect the vision. Depending on the case eye drops or surgery might be needed. This is a same day procedure. The growth can be surgically removed if causes discomfort, affects the vision or for cosmetic reasons. The doctor will use local anesthesia to numb the area and will remove the pterygium. After the surgery, you will need to wear an eye patch for two days and be able to return to your normal activities the next day.

This is a condition that affects the cornea of the eye. The normal cornea is nearly hemispherical in shape. However, in this condition it starts becoming conical (kerato=cornea, conus=conical). The cornea near the centre starts becoming thinner, and thereby, weaker so that it bulges under the influence of the intra-ocular pressure (IOP, the pressure inside the eye).
Nearly hemispherical cornea helps to focus light rays onto the retina. However, this function is significantly affected in Keratoconus. Because of the conical shape, a high degree of induced, causing distorted vision. The normal, case of astīgmatism is
Imaging of the cornea with an instrument called the Pentacam is usually advised. It helps to study the corneal condition in great detail - the corneal thickness, bulge, level of Keratoconus and other parameters.
In the initial stages of Keratoconus, spectacles may suffice in improving vision. However, rigid contact lenses are advised. They help by providing support to the and by partly cornea, its correcting reduce astigmatism and improve vision. A new modality of treatment called C3R or Corneal Collagen Cross-linking is also helpful. It increases rigidity of the cornea and helps in stopping progression of Keratoconus sometimes even inducing regression. Corneal transplantation may be required in severe cases or those with complications.
