Abstract

Aim: To study the effect of YAG laser capsulotomy on visual acuity with special reference to IOP changes and its correlation to
the energy used in pseudophakics.
A total of 120 cases of pseudophakic eyes having intraocular pressure (IOP) between 10-20 mmHg
were included. After detailed history and ocular examination laser capsulotomy was performed to clear off 4-5mm visual axis. High (>50mJ) and low (<50mJ) energy
groups were divided according to the energy used during procedure. Post- laser IOP was noted immediately, at 1 hour, 2 hour, 4
hours, 24 hours, seventh day and on 1 month by Goldmann applanation tonometer.
Results: 95% of the cases showed improved visual acuity, after laser capsulotomy. Elevated IOP was seen in 75 cases, out of
which 80% of them showed transient IOP rise within 2 hour whereas no elevation was seen in 45 cases. IOP change was
significantly high in high energy group (p=0.000) than in low energy.
