INTRAOCULAR PRESSURE BEFORE AND AFTER THE YAG LASER POSTERIOR CAPSULATOMY.

Abstract

ABSTRACT
BACKGROUND: The most frequent long-term side effect of cataract surgery is posterior
capsule opacification, sometimes it is also called a "secondary cataract".OBJECTIVE: to
evaluate the variations in intraocular pressure change (IOP) before and after Yag laser posterior
capsulotomy (LPC) for posterior capsule opacification (PCO). MATERIAL AND METHODS:
This was a descriptive study which was done on the subjects of posterior capsular opacity (PCO)
in the department of ophthalmology Hayatabad Medical Complex Peshawar. It was conducted
from August 2022 to January 2023. RESULTS: Total 80 patients were included, 48(60%) men
and 32(40%) women. The age was range from 20 to 70 years. Out of 80 patients, 60(75%) cases
were operated by extra-capsular extraction and in 20(25%) patients the lens was removed by
phacoemulsification. The mean IOP is increased immediately and after one hour but it return to
normal after seven days of Yag laser. Similarly the IOP is also raised with increased in the
amount of energy and number of pulses. CONCLUSION: It was concluded that intra ocular
pressure (IOP) is significantly rise after Yag laser capsulotomy for posterior capsular opacity
specially with the increase in the amount of laser energy and number of laser pulses.
