Analysis of corneal topography is becoming more common for evaluating corneal irregular astigmatism.¹ However, irregular astigmatism can also arise from the crystalline lens. An irregular reflex on retinoscopy with normal corneal topography or an abnormal lens contour on slitlamp examination strongly suggests the existence, and gives an estimate of the degree, of lenticular irregular astigmatism. However, it is difficult to evaluate lenticular irregular astigmatism qualitatively and quantitatively. Two cases of lenticonus in patients with Alport syndrome² are presented to show that wavefront sensing can be used to evaluate lenticular irregular astigmatism.

Report of Cases

Case 1

A 52-year-old man sought treatment at our clinic because of a gradual decrease in his vision. His visual acuity was 20/20 OD with a refractive error of -13.5 diopters (D) sphere and -3.5 D cylinder at 5° and 20/25 OS with a refractive error of -14.5 D sphere and -0.75 D cylinder at 170°. Slitlamp examination revealed bilateral anterior . . . [Full Text of this Article]
