Purpose: To describe the intraoperative and postoperative complications and visual acuity outcomes of patients undergoing phacoemulsification and intraocular lens (IOL) implantation after pars plana vitrectomy (PPV).
Methods: The subjects of this study were 102 eyes of 95 patients performed phacoemulsification after vitrectomy from January 2002 to February 2006, followed up for 2 months or longer. Office records of the operating surgeons were reviewed for age, gender, pre-existing retinal disorders, type of cataract, best-corrected visual acuity (BCVA) before and after phacoemulsification, intraoperative difficulties, and postoperative complications. We compared the desired refraction by preoperative data, and postoperative manifest refraction of postoperative 2 months.
Results: The average interval from PPV to phacoemulsification was 10.6 months. Vitrectomized eyes were predominantly nuclear sclerotic cataracts (93.1%). After phacoemulsification, 99 of 102 eyes (97.1%) had same or improved BCVA more than one line. 21 of 102 eyes (11.8%) had intraoperative difficulties or complications. Small pupil requiring epinephrine, zonulysis, anterior chamber depth fluctuation, posterior capsular radial tear and angle recession occurred. There was no significant difference between the desired refraction by preoperative data and postoperative manifest refraction of postoperative 2 months.
Conclusions: Phacoemulsification after pars plana vitrectomy can be performed with a low complication rate and with relatively good visual results.
