Introduction: The denser the PCO there is tendency of more energy to be used, Nd: YAG capsulotomy is associated with significant anterior and posterior segment complications. There are no much studies on impact of Nd: YAG laser energy on the rate of complications and opening patterns of capsulotomy on visual function. Objectives:1] To find out association between the grade and type of PCO with energy used and 2] To compare the visual outcome and complications between Hinged pattern and cruciate pattern PCO capsulotomy. Methodology: The patients are divided into group A and B, group A underwent cruciate and group B underwent Hinged pattern capsulotomy.A Q- switched Nd: YAG laser Initial setting of 1mJ and subsequent increase of 0.5 mJ as necessary used to make opening in the posterior capsule and the number of pulses used to create capsulotomy and summated total laser energy was noted in each case. Patients were followed for 6 months and analysed.Complications, if any, were treated according to standard protocol with proper follow ups respectively for each variety. Results: In this study age of the patients ranged from 16 years to 86 years and the mean age was 62.3+/- 18.2.Maximum energy was required for grade 4 (49 mJ) and least for grade 1(8.5 mJ) more energy was required for fibro-membranous and membranous (49 mJ) and least for fibrous (48.5 mJ).In cases who underwent Hinged pattern, complications like IOL pitting and uveitis are common in Hinged pattern compared cruciate pattern, where IOP spikes is a common complication. Conclusion: Grade and Type of PCO significantly influenced laser energy levels required for capsulotomy, whereas complications are significantly more common when total laser energy was higher.This new technique of Hinged pattern Nd: YAG posterior laser capsulotomy can be performed safely and is thanCruciate pattern of capsulotomy.
