Keratoconus

Keratoconus is a progressive eye condition where the cornea becomes thin and gradually bulges outward into a cone shape, leading to distorted and blurred vision. It typically begins in the teenage years and can worsen over time. Common symptoms include increased light sensitivity, frequent prescription changes, and difficulty with night vision. Treatment options range from specialized contact lenses to advanced procedures like corneal cross-linking and, in severe cases, corneal transplantation.

Common symptoms include increased light sensitivity, glare, frequent changes in eyeglass prescription, ghost images, and difficulty with night vision. In its early stages, vision can often be corrected with glasses or soft contact lenses. As the condition advances, rigid gas-permeable lenses, scleral lenses, or hybrid lenses may be required to provide adequate vision correction.
