Purpose. To assess the visual and refractive outcome of immediate intraoperative vitrectomy and intrascleral intraocular lens implantation using a "standardized" sutureless Yamane technique during cataract luxation in the vitreous chamber as a complication of phacoemulsification. Design. A prospective, interventional, consecutive case series. Materials and Methods. Twelve patients underwent vitrectomy and intrascleral intraocular lens fixation using a standardized Yamane technique as the primary procedure during complicated phacoemulsification. Patients were evaluated preoperatively and 6 months postoperatively for best-corrected distance visual acuity, correspondence to the preoperative refractive target in the spherical equivalent, endothelial cell count, and complications. Results. Mean preoperative best-corrected visual acuity was 1.16 +/- 0.3 logarithm of the minimum angle of resolution (logMAR), the endothelial cell count was 1910.5 +/- 297.64, and target refraction at baseline was -0.197 +/- 0.087. Postoperatively, best-corrected visual acuity was significantly improved; the mean value was 0.05 logMAR +/- 0.06. Mean baseline target refraction in the spherical equivalent was -0.20 +/- -0.09 (range: -0.08 to -0.37), and mean final refraction was -0.44 +/- -0.14 (range: -0.25 to -0.75) with no significant difference p=0.87. No complication was registered intra- and postoperatively. Conclusion. Standardization of the Yamane technique seemed a valuable option for patients who had complicated phacoemulsification to achieve a predictable refractive outcome. Synopsis. The predictable refractive outcome could be achieved with the immediate standardized Yamane technique in patients with intraoperative cataract luxation in the vitreous chamber during phacoemulsification.

Purpose. To assess the visual and refractive outcome of immediate intraoperative vitrectomy and intrascleral intraocular lens implantation using a "standardized" sutureless Yamane technique during cataract luxation in the vitreous chamber as a complication of phacoemulsification. Design. A prospective, interventional, consecutive case series. Materials and Methods. Twelve patients underwent vitrectomy and intrascleral intraocular lens fixation using a standardized Yamane technique as the primary procedure during complicated phacoemulsification. Patients were evaluated preoperatively and 6 months postoperatively for best-corrected distance visual acuity, correspondence to the preoperative refractive target in the spherical equivalent, endothelial cell count, and complications. Results. Mean preoperative best-corrected visual acuity was 1.16 +/- 0.3 logarithm of the minimum angle of resolution (logMAR), the endothelial cell count was 1910.5 +/- 297.64, and target refraction at baseline was -0.197 +/- 0.087.
