Observation of Intra Ocular Pressure Spike Post Nd-Yag Laser Capsulotomy Using Nct & Gat

Abstract

A gradual decrease in vision in patients who underwent cataract surgery a few years previously is commonly caused by a condition called posterior capsular opacification(PCO) for which the safest treatment is Nd-YAG capsulotomy according to the current guidelines. Although the complications are least following this procedure the most commonest is the rise in intra ocular pressure(IOP). In this study we observed the IOP rise following Nd - YAG capsulotomy over a short period of six hours to observe the eyes natural response to rise in IOP and its physiological adaptation in controlling the IOP by its self without any medical intervention.This IOP measurement was done using two different methods.A contact method and another the non contact to also compare the reliability of IOP measurements between the two methods.
