Scleral Shape

Eef van der Worp and colleagues at Pacific University have done some novel research studying the shape of the sclera.  For scleral lens patients this is important because scleral contact lenses needs to conform and fit to the sclera.  Dr. van der Worp has concluded that on average the sclera is non-rotationally symmetric.  In other words, the sclera is not symmetrically round or toric.  This important research will undoubtedly affect future lens design and manufacturing, with a push towards quadrant specific back surface haptics.
