Visual impairment is a global health problem. Cataract is responsible for 50% of blindness worldwide [1].

Posterior capsular opacification is the most common late complication of cataract surgery as a result of proliferation of residual lens epithelial cells overall 25% of patients undergoing extra-capsular cataract surgery develops visually significant PCO within 5 years of the operation [2].

Nd: YAG laser provides the advantage of cutting the posterior lens capsule, thereby avoiding and minimizing infection, wound leaks, and other complication of intraocular surgery. Thus Nd:YAG laser capsulotomy is noninvasive, effective and relatively safe technique [3].

However, this procedure is associated with complications such as- postoperative increased intraocular pressure (IOP), cystoid macular edema (CME), disruption of the anterior vitreous surface, uveitis, lens subluxation, increased incidence of retinal detachment and pitting of the IOL [4].

Laser shots can be applied in several patterns such as “Cruciate or Cross pattern”, “Can opener”, inverted “U-Method” and in a “Circular pattern”. Many authors promote the use of a cruciate pattern in the Centre of the visual axis, with the clinician starting off on both axes away from the Centre to avoid pitting the lens centrally [5].

This study mainly aims to analyze the effect of various forms of PCO capsulotomy openings on visual function after Nd: YAG capsulotomy.
