Scleral Lenses – An Overview

These are a special type of contact lenses. Compared to the usual soft lenses that are prescribed to most people, scleral lenses are larger. That is because they are designed to cover the cornea of the eye. Such lenses are prescribed for people with certain vision impurities and other eye conditions.

Scleral lenses

While soft lenses are designed to cover the cornea, sclera lenses are more significant. They cover the cornea and rest on the whites of the eyes. They are designed to be harder and are gas permeable. That is, they allow oxygen to reach the cornea, being better for maintaining the health of the eyes. They can last for longer periods and provide better vision. Such lenses are prescribed to those who have corneal irregularities or other conditions which makes regular soft lenses unsuitable for them.

Exploring the Different Types of Sclera Lenses

There can be different types of scleral lenses, prescribed as per the requirements or eye conditions of patients:

  • Full Scleral Lenses

These are the largest lenses in this category. They are designed to provide cover between the back surface of the lens and that of the cornea. They are usually prescribed for conditions such as severe ocular diseases, dry eyes, or advanced keratoconus.

  • Mini Scleral Lenses

These rest on the anterior sclera after vaulting over the cornea.

  • Corneo-Scleral or Semi-Scleral Lenses

These rest in the junction between the sclera and cornea. Such lenses are used often for post-corneal grafts, corneal surgeries, or after laser treatments.

Besides offering comfort for the above eye conditions, scleral lenses come with different cosmetic parameters as well such as black sclera red iris contacts.
