Scheimpflug camera device for preoperative assessment in candidates for toric and multifocal intraocular lenses

Abstract

Scheimpflug camera devices enable 3-dimensional analysis of the cornea and anterior segment. Evaluation of the posterior corneal curvature, total corneal astigmatism and corneal higher order aberrations, including spherical aberration, are important for patient selection for toric and multifocal intraocular lenses. The magnitude and axis of posterior astigmatism influence the total corneal refractive power. Assessment of the total corneal power is particularly important in eyes with corneal abnormalities such as keratoconus or in eyes after corneal refractive laser surgery.
