Objective: To determine the frequency of raised intraocular pressure in pseudophakic undergoing Nd YAG laser posterior capsulotomy.
To compare the frequency of raised intraocular pressure in pseudophakic undergoing high and low energy Nd YAG laser posterior capsulotomy
Methods: This Descriptive case series included 140 patients with pseudophakic posterior capsular opacity. After dilating the pupils with tropicamide Nd YAG laser posterior capsulotomy was performed and the total amount of energy used was noted. The frequency of raised IOP in post-laser patients and comparison of frequencies of raised IOP undergoing high and low energy Nd YAG laser posterior capsulotomies (≤ 50 MJ labeled as low energy and > 50 MJ labeled as high energy) were calculated
Results: The mean age was 57.37 ±8.74. Mean pre laser IOP was 15.15 and post-laser IOP was 17.50. The rise in IOP was normal in 82.9% and raised in 17.1%. In lower energy group normal IOP was found in 35.7% and raised in 2.9%. In a higher energy group, normal IOP was found in 47.1%, and raised IOP was found to be 14.3%.
Conclusion: Higher the energy used during the Nd YAG laser posterior capsulotomy procedure, more is the chance of a rise in post-laser intraocular pressure as compared to those in which lesser energy was being used.
