Abstract Details


Posterior capsular opacification (PCO) represents the most common delayed complication following cataract surgery. Nd:YAG laser capsulotomy is the standard procedure for the treatment of PCO. Effect of vitreous body and vitrectomy on PCO evolution remains unclear. The present study aims to compare patients undergoing cataract surgery with and without vitrectomy in terms of the progression of PCO and development of complications secondary to Nd:YAG laser capsulotomy.

We conducted a retrospective study based on the review of 82 medical records (n=104 eyes). Medical records were randomly selected on the basis of exposure to Nd-YAG laser capsulotomy between 2005 and 2012. The average progression time of PCO was defined by the measured interval between the time of cataract surgery and Nd-YAG laser capsulotomy.


The mean age of patients was 63.86�11.96 years in patients with cataract surgery alone (group 1) and 56.96�11.03 years in patients with vitrectomy (group 2) (p = 0.01). Analysis of the average progression time of PCO revealed no significant difference between the two groups (p = 0.21). The mean follow-up time showed no significant difference (p = 0.28) with a follow-up time of 6.4�1.6 years and 6.0�1.5 years in groups 1 and 2, respectively. A significant difference in the proportion of complications secondary to Nd:YAG treatment of PCO occurring after capsulotomy was observed between the two groups (p = 0.0423).


The average interval of progression of PCO is similar between patients undergoing cataract surgery alone and patients with a cataract surgery combined with vitrectomy. Although Nd:YAG laser capsulotomy usually appears as a safe procedure in the treatment of PCO, more complications have been observed in patients undergoing the combined approach in our study. This should guide the decision to the Nd:YAG laser capsulotomy treatment and should be considered in the monitoring following laser treatment.
