Abstract

Background: Phacoemulsification with PCIOL decrease the intraocular pressure proportional to
the intraocular pressure seen preoperatively. Various preoperative factors are associated with the
reduction of IOP postoperatively.
Aim: The present study was conducted to assess the cataract surgery phacoemulsification with
PCIOL implantation on intraocular pressure postoperatively and the to assess the relationship
between preoperative ocular parameters including AL ACD, AL, and CCT with IOP change
postoperatively.
Methods:In 262 subjects from both the genders with cataract were treated surgically with
phacoemulsification and PCIOL implantation. Following surgery, all the subjects were followed
up on 1st operative surgical day and 1 month postoperatively for ocular biometric parameters and
reduction in IOP.
Results:BCVA in the study subjects via LogMAR chart was 1-0.76 preoperatively and was 0.16-
0 postoperatively. BCVA using Snellen chart was 72% preoperatively which reduced to 67%
postoperatively. ACD preoperatively was 3.25±0.26 which increased significantly to 3.64±0.29
(p<0.001). Mean IOP in the operated eyes was 13.42±1.98mm Hg which decreased
postoperatively to 11.50±1.68 significantly (p<0.001). It was seen that mean IOP preoperatively
was 13.46±1.96 mmHg which decreased postoperatively to 11.56±1.64 mmHg. The change in
mean IOP at 1 month recall was 1.92±0.59 mmHg. The IOP change at 1 month in percentage
was 14.11%. This change in mean Intraocular pressure was statistically significant with p<0.001.
