Relationship between Amount of Energy Used and Rise in Iop in Cases of Neodymium: Yttrium-Aluminum-Garnet Laser Posterior Capsulotomy

Journal Title: Ophthalmology and Allied Sciences - Year 2019, Vol 5, Issue 1

Abstract

Objective: To find the relationship between the amount of energy used and significant rise in IOP (>5mmHg) after Nd:YAG laser posterior capsulotomy. Materials and Methods: 100 pseudophakic eyes of adults age 30-70 yrs of either sex having PCO are included. Amount of laser energy (milli joules) used in each case noted, IOP was measured just before the procedure and at 1,4,24 hours after procedure in each case. Total energy used is grouped into low (<20mJ), intermediate (20-40mJ), high (>40mJ). Change of IOP at 3 post laser recording times categorized into 1) No change 2) Rise of 1-5mmHg 3) >5 mm Hg. Results: 100 pseudophakic eyes, 61 males and 39 females. Number of patients in low, intermediate, high energy group were 43,45,12 respectively and significant rise in IOP (>5mm Hg) noted are 6/43 (13.9%), 12/45 (26.6%), 8/12 (66%) respectively. Significant rise in IOP noted at 1,4,24 hours post laser application are 7/26 (26.9%), 15/26 (57.6%), 4/26 (15.3%) respectively. Conclusion: There is a directly proportionate relationship between the amount of laser energy used and IOP rise.
