A regular/normal/non-diseased cornea is characterized by a prolate surface,
with no indices of irregularity, warpage or distortion. For consistency, the term regular
cornea will be used in this text. Anterior corneal surface elevation and posterior corneal
surface elevation of a regular cornea which do not exhibit ectasia or irregularities of
either surface. These patients present with common refractive errors: myopia, regular
astigmatism, hyperopia and presbyopia. Prescribing scleral lenses for patients with
regular corneas or switching patients from other modalities to scleral lenses is very
feasible. First, practitioners determine the need, which is improving vision and/or
comfort. Scleral lenses can significantly enhance the lens wearing experience of regular
cornea patients, especially in astigmatic, presbyopic or marginal dry eye patient
populations. For regular cornea patients and the correction of common refractive errors,
the risk-to-benefit ratio needs to be evaluated and an appropriate lens selected. In
conclusion, scleral lenses are becoming part of practitioners’ standard armamentarium
to improve the contact lens experience of their patients.
