A scleral lens sits on the sclera of the eye and vaults over the cornea, virtually eliminating friction and discomfort. This “dome” creates a new optical surface to replace the damaged cornea. Moreover, the reservoir of saline solution between the back the lens and the front of the cornea perpetually keeps the eye in a liquid environment, providing the ideal environment for ocular healing.

Scleral lenses, on the other hand, are larger in diameter and spread their weight over a much greater, less sensitive area. Furthermore, having the lens vault over the cornea protects it from any abrasion or external irritants. It is made up of highly oxygen permeable materials and provides a soothing bath of artificial tears that refresh the ocular surface. Scleral lenses improve comfort and provide clear vision to those with corneal aberrations, whether due to existing eye conditions or following corneal surgery.

TYPES OF SCLERAL LENSES:

• Corneo-scleral lenses and semi-scleral lenses are much larger than typical GP lenses and rest right by the junction between the cornea and the sclera.
• Mini-scleral lenses vault over the whole corneal surface and rest on the anterior sclera.
• Full scleral lenses are the biggest in size and offer the most clearance between the back of the lens and the cornea.

Advantages of Scleral Lenses:

• Scleral Lenses provide more comfort and improved vision: scleral lenses are composed of highly breathable gas permeable material, which ensures that ample oxygen reaches the eye, leading to healthy eyes and comfortable lens wear.
• The large size of the lens protects your eyes from debris, dust, and allergens, providing a perfect solution for those suffering from eye allergies.
• It provides greater durability, easier handling and a lower risk for complications.
• Sclera lenses are designed for the patients like Keratoconus, Pellucid Marginal Degeneration, Post Corneal Transplant Surgery, Severe Dry Eye, Corneal Scars (trauma, infection), Large amounts of Astigmatism, Discomfort with current contacts

For all these conditions, scleral lenses offer a more comfortable, secure fit and improved vision
