Abstract
Purpose
To report a case of corrected residual refractive error after cataract surgery with sulcoflex piggyback intraouclar lens (IOL).
Case summary
A 77-year-old man was diagnosed as having hypermature cataract in the right eye and his corrected visual acuity in the same eye was hand-motion before surgery. Refractive error was +9.0 diopter (D) 6 months after conventional cataract surgery in the right eye. The authors performed additional cataract surgery using a piggyback method inserting a +10.0 D IOL in the ciliary sulcus. Four weeks after surgery, his refractive error was −1.25 D, visual acuity increased to 120/200 and 60/200 (with and without correction, respectively). No complication was observed during follow-up time and the patient was satisfied with his results.

Sulcoflex has a concave posterior surface to avoid contact with primary IOL. (B) Comparison between conventional piggyback IOL (left) and sulcoflex IOL (right). Specific design for sulcoflex IOL reduces physical contact between 2 IOLs. |
