Overview of Scleral Lenses

Scleral lenses are large diameter gas permeable lenses that rest on the sclera, the white outer layer of the eye, and vault over the cornea. Unlike smaller corneal lenses, scleral lenses are designed to manage more complex corneal conditions. They provide a smooth optical surface over irregular corneas, offering enhanced comfort and visual clarity. For example, in patients with keratoconus, a condition where the cornea becomes cone-shaped and distorts vision, scleral lenses can significantly improve visual acuity by creating a more regular refractive surface.

Key Functions of Scleral Lenses

  • Optical Correction

    Example Example

    Correcting severe astigmatism

    Example Scenario

    In cases where traditional contact lenses do not provide adequate vision correction due to irregular corneal shapes, scleral lenses are utilized. Their larger diameter and unique design enable them to correct refractive errors that other lenses cannot handle, offering sharp vision.

  • Therapeutic Protection

    Example Example

    Managing ocular surface diseases

    Example Scenario

    For conditions like severe dry eye or Stevens-Johnson syndrome, where the eye's surface is compromised, scleral lenses protect the cornea from the environment and from the mechanical friction of blinking by maintaining a fluid reservoir that keeps the eye moist.

  • Support for Surgical Recovery

    Example Example

    Post-surgical corneal protection

    Example Scenario

    After surgeries such as a corneal transplant, scleral lenses help protect the new corneal graft or ease discomfort during the healing process by shielding the sensitive surgical area from external irritants and maintaining a stable tear film.

Ideal Users of Scleral Lenses

  • Patients with Complex Corneal Irregularities

    Individuals suffering from keratoconus, pellucid marginal degeneration, or those who have undergone corneal grafts, often find regular contact lenses ineffective. Scleral lenses offer them improved vision and comfort due to their ability to form a tear-filled vault over the cornea.

  • Individuals with Severe Dry Eyes

    People who experience severe dry eye symptoms that cannot be managed by typical treatments may benefit from the moisture-retaining capabilities of scleral lenses. The design of these lenses helps maintain a hydrating reservoir, making them ideal for those with Sjögren's syndrome or other similar conditions.
