Anterior lenticonus detected by wavefront aberrometry.

Abstract

To illustrate the utility of wavefront aberrometry in delineating a subtle lenticular abnormality responsible for decreased best-corrected visual acuity in a patient. Case report. Clinical data, corneal topography, and wavefront aberrometry with separation of corneal and lenticular components of the higher-order aberrations are analyzed in a patient who presented for refractive surgery evaluation. Clinical evaluation indicated that the cause of visual loss was lenticular, and wavefront aberrometry indicated high negative spherical aberration, leading to the diagnosis of anterior lenticonus. Wavefront aberrometry has an adjunctive and distinctive role in the preoperative screening process for refractive surgery candidates and in those with subtle unexplained loss of best-corrected visual acuity.
