Scleral lens

A Scleral lens (pronounced: skleer-ul lens) is a type of contact lens that vaults over the cornea and rests on the white part of the eye, known as the sclera. This type of lens is larger than a typical contact lens and is designed to cover a larger area of the eye.

Etymology

The term "scleral lens" is derived from the word "sclera", which is the white outer layer of the eyeball. The term "lens" comes from the Latin word "lens", which means "lentil", due to the similarity in shape.

Usage

Scleral lenses are often used for individuals with keratoconus, dry eye syndrome, and other corneal irregularities. They can also be used for those who have difficulty wearing traditional contact lenses.

Advantages

Scleral lenses have several advantages over traditional contact lenses. They provide a smooth surface for light to enter the eye, which can improve vision for individuals with corneal irregularities. They also create a reservoir of fluid that can provide relief for those with dry eye syndrome.

Disadvantages

Despite their advantages, scleral lenses also have some disadvantages. They can be more difficult to insert and remove than traditional contact lenses, and they may not be suitable for all individuals. Additionally, they can be more expensive than other types of contact lenses.
