Medically Necessary Contact Lenses: Essential Visual Support for Complex Eye Conditions

Soft contact lenses can be custom-designed for specific conditions, such as mild asymmetry or minor corneal irregularities. They are available as disposable or extended wear options. In some cases, custom soft lenses are used when the refractive error is significant but does not require a more rigid support system.

RGP lenses are durable and maintain their shape on the eye, offering clear vision even in cases of severe refractive errors or irregular corneal surfaces. Patients with keratoconus or high astigmatism often benefit from these lenses because they create a new refractive surface. Even though they may feel less forgiving initially compared to soft lenses, the visual improvement is unparalleled for certain conditions.

Hybrid lenses combine the clarity of RGP lenses with the comfort of soft lenses. These lenses offer a rigid center for optimal vision along with a soft peripheral skirt that reduces discomfort on sensitive eyes. They are especially useful for patients who need the precise optical correction of a rigid lens but desire the extended comfort of a soft lens.

Scleral lenses are larger in diameter and rest on the sclera (the white part of the eye) rather than the cornea. This design is particularly beneficial for patients with severe corneal irregularities, such as those seen in advanced keratoconus or corneal scarring. With a fluid reservoir between the lens and the cornea, scleral lenses also provide long-lasting moisture, which is a game-changer for those suffering from severe dry eye syndromes.

Prosthetic lenses are used both for therapeutic and cosmetic purposes when the eye’s appearance or function is significantly compromised by injury or disease. These lenses are custom-crafted to improve vision and also to address issues like light sensitivity by blocking aberrant light from entering the eye. They are essential for patients with congenital abnormalities or post-traumatic situations that require both functional and cosmetic reconstruction.
