Designing scleral lenses to fit over or around irregularities poses unique fitting issues. A new corneo-scleral topography device and software (sMap3D, Precision Ocular Metrology) is now able to accurately map these irregularities.
Toric haptic scleral lens designs are prescribed more often than in previous years. Recent interest in mapping the sclera and conjunctiva indicates that scleral shape demonstrates interocular and individual variability, which may explain the difficulty in fitting some patients with scleral lenses.
