Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The purpose of this study is to compare measurements of eye pressure at the end of the surgery, comparing the ability of a gloved finger or sterile cotton-tipped applicator ("Q-tip") to accurately measure intraocular pressure against a standardized instrument designed for this purpose.
