What is the Cornea?

The cornea is a transparent layer located at the outermost part of the eye and plays a critical role in visual function. It focuses the light coming into the eye and provides a clear image. It also protects the eye against external factors. As part of the eye's optical system, this transparent structure is an important element that determines the quality and acuity of vision. The proper curvature of the cornea ensures that light is focused correctly on the retina, providing a clear visual experience. It is also the eye's first line of defense against threats from the outside world. Therefore, a healthy cornea is vital for good vision and eye health.

How is Cornea Transplant Surgery Performed?

Corneal transplantation is a delicate surgical procedure performed using different techniques and methods. This operation involves replacing the entire cornea or only certain layers of it. So, how is corneal transplant surgery performed? Corneal transplant surgery is performed by removing all layers of the cornea and completely replacing the donor cornea. This method is especially preferred for superficial corneal diseases.

This offers a faster healing process. For the problem in the middle layer, the middle layer of the transplanted cornea, called the stroma, is replaced. Donor stroma is placed in place of the damaged stroma. This can speed up the healing process and improve visual function. There are also more specific techniques that aim to regenerate the inner layers of the cornea. Some methods only transplant the innermost layer of the cornea.

    Symptoms of Corneal Thinning

    Corneal thinning is defined as a condition in which the cornea loses its normal thickness and becomes thinner. Symptoms of corneal thinning are often associated with an eye disease called Keratoconus. Keratoconus is a progressive condition that causes thinning and deformity of the upper central part of the cornea.

    In this disease, the cornea loses its normal rounded shape and becomes more pointed and conical. This prevents light from focusing properly and leads to visual impairment. Keratoconus usually occurs between the ages of 10-25. It can be associated with various factors such as genetic factors and allergies. In the early stages of this disease, no obvious symptoms may be noticed.

    However, as it progresses, symptoms such as blurred vision, sensitivity to light, a feeling of scratches or cuts in the eye and headaches may be observed. In addition, patients often begin to experience incompatibility when wearing glasses or contact lenses, as these optical aids cannot provide adequate correction as the shape of the cornea changes. Symptoms of corneal thinning can vary depending on the rate and severity of disease progression. Symptoms such as blurred or altered vision, increased sensitivity to light and discomfort in the eye may indicate that the disease is progressing. Early diagnosis is critical for treatment success. Timely interventions can halt or slow the progression of the disease. This significantly improves the quality of life of patients.
