The cornea is the transparent part of the eye found in the front portion covering the pupil, iris, and anterior chamber. The cornea works to refract light for clear vision, but can become damaged due to several factors including disease, hereditary conditions, or scarring from significant injuries. While the cornea is typically self-healing from smaller scratches or tears, some patients may require a surgical procedure to repair (or, in some cases, replace) their corneal tissue. The ophthalmologists at Boston Vision can recommend the best treatment option for you to restore your health and vision.
Phototherapeutic Keratectomy (PTK) is a laser surgery designed to repair the cornea in cases of corneal dystrophy, corneal scars, corneal infections, or other complications.
If the cornea is significantly damaged or scarred, a cornea transplant using tissue from an organ donor may be performed to restore the patient’s vision and protect their health.
Another solution involving an eyedrop medication and UV light to help make the weakened tissue in your cornea stronger. The “crosslinking” term stems from the strengthened bonds of collagen fibers in your eye, thus stopping progressive keratoconus from worsening.
