Design outcomes

Primary

MeasureTime frame
To measure pre-operative, intra-operative and post-operative pupil size and to record intra-operative and post-operative complications if any, with each method.Timepoint: Patient will be followed up on Day 1, Day 7 and 1 month. Pre-operative pupil size will be measured post-mydriasis before the surgery Intra-operative pupil size will be measured a Before entering the anterior chamber b Post OVD injection c Post mechanical dilatation d End of the surgical procedure Post-operative pupil size will be measured on Day 7 and 1 month—

Secondary

MeasureTime frame
1 To record the Visual Acuity before and after the surgery. 2 To measure pre-operative and post-operative endothelial cell count using specular microscopy. 3 To compare the above parameters recorded in each method used. Timepoint: Visual acuity will be recorded pre-operative and post-operatively Day 7 and 1 month. Specular microscopy will be recorded pre-operatively and 1 month post-operatively.—
