Abstract

Fifty percent of blindness worldwide is attributed to cataract, and cataract surgery is the most common
surgery performed by ophthalmologist. Cataract surgery has its effects on the structures of the anterior
segment, and hence the aqueous humor outflow, these may include more space in anterior chamber, wider
angles, as the thick aging lens would be replaced by the thinner intraocular lens. So this study to investigate
the changes in anterior segment parameters and its correlation to IOP changes after phacoemulsification.
A prospective Cohert study that was done at Ibn Al-Haitham Teaching Eye Hospital for patients planned
to have phacoemulsification, for 55 patients during 8 months, from the 1st of July/2018 until the 28th of
February/2019. The data included full preoperative and postoperative assessment, key parameters were:
axial length measurement, intraocular lens, anterior chamber depth, anterior chamber volume, anterior
chamber angle for the four quadrants and their mean value was calculated. It was done before the operations
and after two months from the operation. Findings were the mean age of the study group was 56.9years,
with 30 (54.5%) males and 29 (52.7%) right eyes,. The mean axial length was 23.12±1.11 mm. There were
statistically significant differences in preoperative compared to postoperative values of IOP (decreased by
4.55 mmHg), anterior chamber depth (increased by 0.74 mm), volume (increased by 32.75 µl), and mean
angle (increased by11.78 degree) maximum inferiorly (12.31 degree) and minimum superiorly. There were
no statistically significant correlation between IOP changes with anterior chamber depth, volume, or angles,
but there was a statistically significant correlation with preoperative IOP .Conclusions cataract surgery
significantly decreases the IOP, and increase anterior chamber depth, volume, and angle. The decrease in IOP
does not correlate with anterior chamber depth, volume, and angle. The decrease in IOP was significantly
higher in patients with higher preoperative values of IOP.
