title: Intraoperative and Immediate Postoperative Outcomes of Cataract Surgery using Phacoemulsification in Eyes with and without Pseudoexfoliation Syndrome.
abstract: BACKGROUND
  To compare the intraoperative and immediate postoperative behavior and complications in eyes with pseudoexfoliation (PEX) syndrome with eyes having senile cataract without PEX during cataract surgery using phacoemulsification (PKE).
  
  
  METHODS
  In this prospective study, 68 eyes of 68 patients were divided into two groups: Group 1 (test) comprised 34 eyes with immature senile cataract with PEX and Group 2 (control) included 34 eyes with immature senile cataract without PEX and any coexisting ocular pathology. Phacoemulsification (modern cataract surgery) was performed on both groups through stop and chop technique and comparative analysis of the incidence of intraoperative and immediate postoperative complications was made.
  
  
  RESULTS
  There was no significant difference in rates of intraoperative complications between PEX (2.9%) and Control (0%) group. The mean pupil diameter was significantly smaller in Group 1 (p<0.001). No eye in either group had phacodonesis. 58.8% of eyes in Group 1 and 29.4% in Group 2 had a harder cataract (nuclear sclerosis) ≥ grade 3 (p=0.017). PKE was performed in all eyes with cataract in both groups. Intraoperative complication (zonular dialysis (dehiscence) was encountered in only 2.9% (1 case) of eyes with PEX. PC (posterior capsule) tear (rent) with vitreous loss was seen in 2.9% eyes of Group 1 and none in Group 2. Postoperatively, IOP (intraocular pressure) and aqueous flare response were comparable between the groups. Significantly higher inflammatory cell response was observed in Group 1 (p=0.014). BCVA (best corrected visual acuity) using Snellen chart with pinhole on postoperative day1 was significantly better in the control group compared to the group with PEX (p=0.027).
  
  
  CONCLUSIONS
  Phacoemulsification can be safely performed by experienced hands in cataractous eyes with PEX. The incidence of intraoperative and immediate post-operative complications in eyes with PEX was not significantly different compared to eyes without PEX in our study. Further studies among a larger population are required.
