Graftas

Graftas, also known as graftascope or grafted lenses, are a type of contact lens designed for specific medical purposes, primarily in ophthalmology. They are not standard soft or rigid gas permeable lenses used for general vision correction. Instead, graftas are often utilized in post-surgical scenarios, particularly after corneal transplants or other procedures that involve grafting tissue onto the cornea.

The primary function of graftas is to provide a smooth refractive surface over a compromised or irregularly shaped cornea. This can help to improve vision by compensating for the unevenness and irregularities that may persist even after the surgical graft has healed. They act as a temporary or long-term optical correction, similar to how a standard contact lens reshapes the eye's optical power, but with a focus on managing the unique challenges presented by corneal grafts.

These lenses are typically custom-made to fit the specific contours of the patient's eye and the grafted tissue. Their design and material properties are chosen to promote comfort, oxygen permeability, and stability on the ocular surface, which is crucial for the health of the grafted cornea. The use of graftas is generally under the close supervision of an eye care professional, who will determine their suitability, fitting, and wearing schedule. They represent a specialized tool in the management of complex corneal conditions and post-operative care.
