Specialized contact lenses are prescribed when standard vision correction methods, such as eyeglasses or regular contact lenses, are insufficient to address specific ocular conditions. These lenses are designed to manage and improve vision affected by medical issues rather than refractive errors alone. Examples include lenses used to treat keratoconus, a progressive thinning of the cornea; lenses for managing corneal irregularities after surgery or trauma; or lenses that deliver medication directly to the eye.
These custom-fitted lenses offer significant benefits beyond improved visual acuity. They can protect the cornea, alleviate pain, and prevent further corneal damage in certain conditions. Historically, the development of these lenses represents a crucial advancement in treating complex eye diseases, often providing a non-surgical alternative or acting as a bridge to surgical intervention. The ability to precisely customize lens parameters allows for a more tailored and effective treatment approach.
