Abstract
To evaluate the safety and 1-year outcome of the intraocular lens (IOL) scaffold technique in eyes with soft to moderate nuclear remnants after intraoperative posterior capsule rupture (PCR). Single-center, retrospective, interventional, noncomparative, consecutive case series. A total of 20 eyes of 20 patients who had intraoperative PCR underwent IOL scaffold surgery in a tertiary clinic. A retrospective analysis of medical records of a consecutive series of patients who underwent IOL scaffold surgery from August 2011 to February 2013 was reviewed. All surgeries were performed by a single surgeon, and a 3-piece, 6.0-mm optic, acrylic, foldable IOL with a modified C-loop haptic configuration was implanted in all eyes. The preoperative and postoperative parameters evaluated were uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), specular microscopy, gonioscopy, ultrasound biomicroscopy, central macular thickness, intraocular pressure (IOP), and anterior and posterior segment inflammation. The final visual outcome at 1 year was evaluated. At 1-year follow-up, the mean postoperative UDVA and CDVA in Snellen's decimal equivalent was 0.58 ± 0.15 and 0.90 ± 0.17, respectively. The IOL was placed in the sulcus for 14 eyes and in the capsular bag for 3 eyes, and glued intrascleral fixation of IOL was performed in 3 eyes. The mean postoperative refractive error at the final examination was -0.4 ± 0.05 diopter (standard error of mean). Postoperative CDVA of 20/20 and 20/30 was achieved in 75% (15 eyes) and 25% (5 eyes), respectively. There was no correlation between preoperative specular count and percentage loss of cells (P = 0.602; r(2)=0.015). The mean central macular thickness at 1 year was 182.5 ± 11.79 μm. Clinical macular edema was observed in 1 of 20 eyes (5%). The IOL scaffold provided an effective, relatively noninvasive means of emulsifying moderate to soft nuclear remnants in eyes with intraoperative PCR, with a good visual outcome and a favorable complication rate.
