Effect of Nd: YAG laser capsulotomy on IOP rise and its variation with energy used

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. Materials and Methods: A total of 120 cases of pseudophakic eyes having intraocular pressure (IOP) between 10-20 mmHg were included. After detailed history and ocular examination including visual acuity, slit lamp biomicroscopy, fundus and applanation tonometry, laser capsulotomy was performed to clear off 4-5mm visual axis. High (>50mJ) and low (<50mJ> 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. Conclusion: Post- laser IOP rise is minimal and transient. It varies with the amount of energy used. Routine pre and post antiglaucoma medication can be avoided and minimal laser energy should be used.
