Ciliary sulcus implantation of intraocular lens in manual small incision cataract surgery complicated by large posterior capsule rupture.

The present study aimed to evaluate the safety and efficiency of ciliary sulcus implantation of intraocular lens (IOL) in patients that had undergone manual small incision cataract surgery (MSICS) complicated by large posterior capsule rupture (LPCR). A total of 11 eyes taken from 11 patients in Brazzaville, Republic of the Congo, that had experienced LPCR following MSICS were included in the current study. A rigid single-piece IOL (5.5 mm optic, 12.50 mm overall length) was implanted into the ciliary sulcus. Postoperative follow-up assessments evaluated visual acuity, anterior segment biomicroscopy, IOL centration and position, and fundus biomicroscopy. The median follow-up time was 3.7 months (range, 2-6 months). All patients experienced vision improvement: Uncorrected visual acuity 2 months following surgery was 0.3-0.5 in 9 patients and >0.5 in 2 patients. Postoperative complications included pronounced anterior segment inflammation (1 patient), mild corneal endothelium edema (3 patients), residual cortex (1 patient) and intraocular pressure elevation (1 patient). Significant IOL decentration and tilt were not observed in any patients. The results of the present study indicate that ciliary sulcus implantation of a rigid single-piece IOL may be a feasible and effective method of treating patients that have experienced LPCR complications following cataract surgery, as it provides satisfactory visual acuity outcomes. Appropriate intraoperative management may reduce the incidence of postoperative complications.
