What are Scleral Lenses?

Scleral lenses are the latest innovation in contact lens technology.  These lenses are made from a rigid gas permeable material (RGP) found in standard sized lenses.  Scleral lenses are much bigger than standard gas permeable lenses.  Since they are bigger, they rest on the white portion (sclera) of the eye and vault over the clear covering of the front of the eye (cornea).  Scleral lenses do not rotate or move when blinking and fits underneath the eyelids allowing comfortable wear throughout the day. 

How can Scleral Lenses help me?

  • Astigmatism
  • Keratoconus
  • Corneal Transplant
  • Dry Eye or other forms of corneal disease
  • Post-Lasik, RK, PRK
  • Trauma-damaged corneas

Many of the conditions listed above cause the cornea to have an irregular shape.  In the case of astigmatism the cornea is shaped like a football instead of a baseball (round).  Traditional soft contact lenses tend to rotate on the eye resulting in blurred vision, fluctuation in vision, and discomfort.  Scleral Lenses are ideal for irregular shaped corneas because they are made from a firm lens material and vault over the cornea.  This allows the contact to provide a new regular surface over the irregular cornea.  

Scleral lenses are also available for bifocal and multifocal wearers.

Each Scleral Lens is custom-fabricated to the unique shape of your eyes.  If you are over 40 years old and need reading glasses, the lenses can also be custom-designed to allow for clear vision when looking at far, at the computer, and when reading up close.
