Overview

The RSa and RSb lenses are designed for the Post-Surgical cornea where either Refractive Surgery or Corneal Transplant Surgery has been performed. This RGP lens design optimizes visual acuity while providing a stable & comfortable fitting relationship.

RSa

Versatile enough to fit all post surgical conditions, this lens easily and consistently provides patients with excellent comfort and visual acuity while fitting within the corneal surface. A combination of spherical and aspheric curves create alignment with the peripheral cornea and slight vaulting of the surgically altered central cornea. Standard diameters are used for PKP patients, and larger diameters are used for post refractive patients.

Toric parameters can also be incorporated into this lens design to address patients with significant astigmatism.

RSb

This lens features all the versatility of the RSa in consistently providing patients with excellent comfort and visual acuity. It also features secondary base curve geometry for improved edge clearance on post refractive patients having excessively steep peripheral corneas. A larger than standard diameter is used to aid lens centering.

Toric parameters can also be incorporated into this lens design to address patients with significant astigmatism.
