    Author: Lee NY, Park SH, Joo CK.
    Journal: Retina; 2009 Apr; 29(4):487-91. PubMed ID: 19174715.
    Abstract:
    PURPOSE: To describe the visual acuity outcomes of patients undergoing phacoemulsification and intraocular lens implantation after pars plana vitrectomy, and to compare of refractive errors after phacoemulsification and intraocular lens implantation in the cases of vitrectomized eyes and nonvitrectomized eyes. METHODS: The subjects of this study were 45 eyes performed phacoemulsification after vitrectomy from January 2004 to February 2007. Office records were reviewed for best-corrected visual acuity before and after phacoemulsification. In 45 vitrectomized eyes (Group V) and 50 nonvitrectomized eyes (Group P), we compared the predicted refraction by preoperative data, and actual postoperative refraction of postoperative 2 months. RESULTS: The average interval from pars plana vitrectomy to phacoemulsification was 11.5 months. In Group V, 41 of 45 eyes (91.1%) had improved best-corrected visual acuity more than one line, after phacoemulsification. Although, more hyperopic shift was noted in Group V than Group P, there was no significant difference between the predicted refraction by preoperative data and postoperative manifest refraction in both groups. CONCLUSION: Phacoemulsification after pars plana vitrectomy showed no significant difference between the predicted refraction by preoperative data and the actual postoperative refraction.
