Advantages:

The removal of the crystalline lens combined with pars plana vitrectomy is advantageous in order to completely remove the vitreous body and to spare the patient from further surgery. However, when pars plana is performed to remove an epiretinal membrane (ERM) and internal limiting membrane (ILM) and is combined with phacoemulsification, a higher incidence of postoperative cystoid macular edema (CME) may occur.

Methods:

One hundred and ninety eyes underwent 23-Gauge transconjunctival sutureless pars plana vitrectomy for ERM and ILM removal. Among these, eighty-nine surgeries were combined with phacoemulsification and IOL implantation.

Effectiveness / Safety:

Non-combined group: 10 eyes (9.9%) showed postoperative CME. Six of them already had CME preoperatively. Five eyes had a postoperative best-corrected visual acuity (BCVA) lower than the preoperative.

Combined group: 10 eyes (11.2%) showed postoperative CME. Two of them already had CME preoperatively. Six eyes had a postoperative BCVA lower than the preoperative.
