Phacoemulsification in vitrectomized eyes: results using a 'phaco chop' technique

摘要

Purpose: To evaluate the intraoperative and early postoperative complications of phacoemulsification using a 'phaco chop' technique in previously vitrectomized eyes.Methods: A prospective interventional case series. Seventy-five previously vitrectomized eyes of 73 consecutive patients underwent phacoemulsification using a 'phaco chop' technique via clear corneal incision. Patients were observed for any intraoperative or early postoperative complications. Results: Fifty-four eyes (72%) had predominant nuclear sclerosis or posterior subcapsular cataract. The intraoperative findings included intraoperative miosis [seen in 21 eyes (28%)] and posterior capsule plaques [in 15 eyes (20%)]. No other significant intraoperative complication (posterior capsule rupture, zonular lysis or dropped nuclei) was observed. In the early postoperative period, one patient had massive serous choroidal detachment, which resolved with conservative treatment. Mean preoperative visual acuity (LogMar scale) was 0.74, which improved to 0.36 postoperatively (p < 0.001).Conclusion: Phacoemulsification using a 'phaco chop' technique is a safe procedure in vitrectomized eyes.
