Scleral Lens

Posted on: May 26th, 2009 by A. Daphne

The Scleral LenseScleral Contact Lenses hold a tear reservoir, which can help patients in two ways.  First,  it is able to  mask irregularities of the cornea improving vision even when glasses and soft contact lenses can’t.  The second way, and one that is unique to scleral lenses, is that the reservoir provides a therapeutic effect by continually bathing the cornea.  Here is a photograph of a cross section of a scleral lens on a patient’s  eye.  The liquid reservoir has been highlighted with a green dye for photographic and observational purposes.  Normally the reservoir is clear.  To the left of the reservoir is the cross section of the scleral lens and to the right of the reservoir is the cross section of the cornea.
