Purpose: : The estimated number of keratoconus patients is still growing. In The Netherlands more than 8000 keratoconus patients need correction with rigid gas permeable (RGP) contact lenses or RGP scleral lenses. In this study we demonstrate scleral lens fitting in keratoconus patients.

Methods: : RGP scleral trial lenses, designed according to axial profile increments, increasing or decreasing corneal sag projection from plane of the sclera, were used to fit 10 keratoconus patients.

Results: : During the fitting procedure, minimum corneal clearance was reached in all patients. Visual acuity was rehabilitated to 20/25 in all patients. Average wearing time was 10 +/– 0.4 hours of the waking day.

Conclusions: : There is an expanding role for scleral lenses in rehabilitation of visual acuity in keratoconus patients. The reasons include the greater oxygen permeability of the material and the simpler fitting processes made available with sealed RGP scleral lenses. This has led to increased usefulness in the management of advanced keratoconus patients.
