Corneal Conditions

Ein Tal provides a unique center specializing in corneal conditions that is at the forefront of its field. The center is staffed by Israel's top corneal specialists, providing treatment from the initial consultation and diagnosis, through special tests and imaging, and treatment of all diseases related to the cornea and conjunctiva, including keratoconus, eye infections, eyelid infections, and eye dryness. The center also handles all types of advanced surgical procedures, including corneal transplants.


What is the Cornea?

The cornea is the transparent tissue that covers the front part of the eye. It protects the eye from foreign objects and allows light to enter the eye without interference.


What are the main corneal conditions treated by Ein Tal?

Ein Tal treats a range of diseases that cause a loss of corneal transparency, such as corneal infections, corneal scarring and edema, and conditions that alter the spherical structure of the cornea, such as keratoconus and pterygium, which result in decreased visual acuity and quality.



Keratoconus is a condition in which the cornea's structure is gradually, progressively altered. The cornea's shape changes from a uniform hemisphere to a steep, conical structure, which leads to corneal distortion.
Symptoms of keratoconus include a gradual decrease in vision, including changes in eyeglass prescription and irregular astigmatism. The disease most often occurs in adolescence and can progress until it stabilizes in the patient's 30s or 40s.


Collagen Crosslinking

This innovative treatment strengthens the corneal tissue, helping to halt the progression of keratoconus and vision deterioration. The treatment is intended for cases of worsening corneal distortion. It hardens the cornea and slows the progress of the disease. The treatment is performed in the operating room and combines applying the vitamin riboflavin to the cornea with the projection of UVA ultraviolet light.


Corneal Transplants

Corneal transplant operations are complex and performed in situations where the patient's sight cannot be improved using more conservative methods. In corneal transplant surgery, the central part of the affected cornea is replaced by a healthy cornea obtained from a donor.

In recent years, new methods have been developed for partial thickness corneal transplants, which are designed to treat corneal diseases involving only the outer or inner layer of the cornea. These surgeries have a higher success rate and sight is restored more quickly.



Pterygium is a degenerative process, commonly found in sunny countries, where reddish tissue grows out of the corner of the eye and extends onto the cornea. Pterygium may cause eye redness, watering, and the sensation of a foreign body. As the tissue grows on the cornea, it can result in a deformed corneal structure and impaired vision. In severe cases, the tissue may cover the visual axis in front of the pupil.
Pterygium is treated through an operation in which the pterygium tissue is removed from the cornea and the adjacent conjunctiva, usually under local anesthesia.
