Purpose: To report a case that underwent successful centration of intraocular lens (IOL) and visual acuity improvement after cataract extraction in a megalocornic eye in our medical center.
Case summary: A 27-year-old man with bilateral megalocorneas came to our medical center. The patient had progressive loss of vision and floaters in both eyes for 3 months. His horizontal corneal diameter was approximately 14 mm in both eyes. The initial best corrected visual acuity was 0.02 in the right eye and 0.5 in the left eye. There was a white cataract and nuclear sclerotic cataract without lens luxation, respectively. The cataract was extracted from the patient’s right eye after anterior continuous curvilinear capsulorrhexis (CCC), the preloaded custom IOL was inserted in the bag, and pars plana vitrectomy was performed. Two months later, after the cataract was extracted from the left eye, optic capture through a posterior capsule was attempted but converted to anterior capsule (reverse optic capture) because of the posterior CCC’s radial tear, and pars plana vitrectomy performed. The IOL had a 6 mm optic and an overall length of 12.5 mm. The IOL in the right eye was decentrated inferiorly in the bag due to a large capsule diameter, but the IOL captured through the anterior capsule in the left eye had good centration. The best corrected visual acuity of both eyes improved to 0.8 without other complications.
