Scleral Contact Lenses from Our Optometrists At Advanced Eye Care Associates in Providence, RI
For a patient excited about trading glasses for the convenience of contacts, learning that contacts are not an option is very disappointing. Trying unsuccessfully to wear them is also a huge letdown. Our Providence optometrists report that for many of these individuals, scleral contact lenses could be a good option. For some patients who visit our Advanced Eye Care Associates practice in Providence, RI for a contact lens fitting, scleral contacts offer many of the advantages of gas-permeable contact lenses over features of soft contacts.
What Are Scleral Contact Lenses?
Scleral contact lenses are a type of rigid gas permeable contact. Each ranges in diameter from 14 mm to more than 20 mm. These contacts take their name because of the portion of the eye they cover. In addition to completely covering the cornea as other contacts do, each lens extends into the sclera, the white part of the eye that comprises its outer wall.
Compared to soft contacts, sclerals offer these benefits:
- Easier to handle
- Fewer risks of complications
- More durable
- Sharper vision
Our eye doctors note that there are several types of scleral contacts. The characterization of each depends on the location of the main contact with the eye’s front surface:
- Full sclerals are the largest. Their design gives the most clearance between the back of each lens and the cornea.
- Corneo-sclerals and semi-sclerals are larger than most gas permeables. They rest near the junction of the sclera and the cornea.
- Mini-sclerals rise over the whole surface of the cornea and come to rest on the anterior portion of the sclera.
Its large size makes it hard to accidentally dislodge a scleral contact. For many patients, comfort is similar to that of a soft lens.
Who is a Good Candidate?
Our eye doctor might determine that a patient who has been labeled unlikely to be suited for traditional contact lenses or who was unable to wear them could be a good contact for scleral lenses after an exam and a contact lens fitting. Scleral gas permeable lenses are particularly beneficial for treating patients with these problems:
- Irregular corneas
- Dry eyes
- Hard-to-fit eyes
For some individuals, scleral contact lenses are simply more comfortable than other types of contacts.
