Background: Posterior capsule opacification (PCO) is common complication of cataract surgery, neodymium:yttrium aluminum-garnet (Nd:YAG) laser capsulotomy is standard treatment. Although, it is non-invasive, it carries risk of complications.

 AIM: to study intra-ocular pressure changes (IOP) and its correlation with energy, shot numbers, size and visual outcomes of capsulotomy; and finding the commonest type of opacification.

Method: This cross-sectional study was conducted in Duhok Eye Hospital from April 2018 to April 2019; 100 patient participants were examined for visual acuity, IOP measurement, and slit lamp examination.

Results: 60 males and 40 females (67%) were from 60 to 79 years, 53 right and 47 left eyes. The mean visual acuity and refraction were found to be higher one week post capsulotomy compared to pre capsulotomy, P value being less than 0.001. Most of female’s jobs were housewives (37.0%), while males’ jobs were ranged from (48.0%) retired (8.0%) workers to (7.0%) office workers. A higher mean in IOP was found two hours post-capsulotomy, P value being 0.025 when it was compared with IOP pre-capsulotomy and IOP one week post capsulotomy. A positive relation between shot numbers and increase IOP two hours post capsulotomy was recorded, P value 0.049.

Conclusions: The commonest type of PCO was membranous. 59.0% of patient’s ha the best corrected visual acuity of 6/6-6/12. IOP rise the was most frequent complication that reached a maximum two hours post capsulotomy, it was associated with shots number. and was normalized within a week
