Contact Lenses for Ortho K

Scleral Lenses

Scleral lenses are used to treat a variety of conditions, including:

  • Keratoconus
  • Glare, Halos, Starbursts and Ghosting
  • Dry Eyes
  • Complications from LASIK, PRK, and RK
  • Pellucid Marginal Degeneration (PMD)
  • Sjogren’s Syndrome

Scleral Lenses are also used for patients who have had the following eye treatments/surgeries:

  • Corneal Cross-Linking (CXL)
  • Corneal Grafts (PKP)

What are Scleral Lenses?

Scleral contact lenses are large-diameter lenses that provide clear and comfortable vision because the lenses do not actually touch the cornea. Instead, scleral lenses vault over the entire corneal surface, resting on the “white” portion of the eye known as the “sclera.” The space between the back and front portions of the scleral lens is filled with unpreserved sterile saline solution, which means that the eye always remains in a liquid environment. Scleral lenses cover a larger portion of the sclera, whereas semi-scleral lenses cover a smaller area. These larger lenses also are more stable than conventional gas permeable contact lenses, which move with each blink because they cover only a portion of the cornea. Moreover, scleral lenses do not fall out, bits of grit do not lodge behind them during wear, and they are surprisingly comfortable to wear when fitted properly.

normal cornea vs keratoconus cornea

For those who have severe dry eyes and cannot tolerate normal contact lenses, scleral lenses are the perfect solution. This is because the space between the cornea and the scleral lens can act as a fluid reservoir, making it more comfortable to wear. Since scleral lenses are custom made for the wearer, fitting scleral contact lenses requires more time and a greater amount of expertise than fitting standard soft or gas-permeable contact lenses.
