To compare posterior capsular opacification (PCO) according to a combined versus sequential procedure of pars plana vitrectomy and cataract surgery.
The subjects were 69 eyes of 65 patients who underwent pars plana vitrectomy and cataract surgery with follow-up for at least 1 year after cataract surgery. Combined surgery was compared to sequential surgery for the PCO rate and the interval between PCO formation and cataract surgery. The study group was divided into 49 eyes of 45 patients who underwent a combined procedure of pars plana vitrectomy and cataract surgery, and 20 eyes of 20 patients who underwent a sequential procedure of pars plana vitrectomy and cataract surgery. The control group was 112 eyes of 88 patients who underwent only cataract surgery. There were no significant differences among the 3 groups for age and the incidence of diabetes mellitus.
The PCO rate was 3.6% in the control group, 12.2% in the study group that underwent a combined procedure and 37.5% in the study group that underwent a sequential procedure; the difference in the PCO rate among the 3 groups was statistically significant (p<.05). There were no significant differences among the 3 groups for the interval between PCO formation and cataract surgery.
This study demonstrated that the PCO rate was lower in the group of patients who underwent combined surgery than in the group of patients who underwent sequential surgery.
