Purpose:
To illustrate the utility of wavefront aberrometry in delineating a subtle lenticular abnormality responsible for decreased best-corrected visual acuity in a patient.
Design:
Case report.
Methods:
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.
Results:
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.
Conclusions:
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.
