Phacoemulsification with corneal astigmatism correction with the use of a toric intraocular lens in a case of megalocornea

Abstract

We report the case of a 49-year-old patient with megalocornea and coexisting corneal astigmatism. The corneal diameter in the right eye was 15.0 mm and in the left eye, 14.9 mm. In both eyes, a nuclear sclerotic cataract developed, with the tendency toward cortical mass swelling in the right eye. The aim of surgical treatment was to remove the cataract with simultaneous correction of corneal astigmatism by implanting an Acrysof toric intraocular lens (IOL). Intraocular lens stabilization was obtained by suturing it to an capsular tension ring (CTR) in the anterior chamber. The IOL-CTR complex was rotated into the lens capsule and aligned with the steep meridian of corneal astigmatism. The surgical technique provides a stable refractive and functional effect in patients with megalocornea and coexisting cataract and corneal astigmatism.
