This study is a Single site, single-masked, randomized, prospective, observational study of the efficiency of the hybrid tip in removing cataract grade 3 & 4 in high and low intraocular pressure (IOP) settings. Subjects will be assessed pre-operatively, operatively and at 1 day and 1 week post-operatively. Clinical evaluations will include measurement of visual acuity, central corneal thickness, IOP, visual analog pain scale, and slit lamp examination.
The objective is to assess the efficiency (as measured by phaco time, aspiration time, and fluid use) of the hybrid tip in removing cataract grade 3 & 4 in high and low intraocular pressure (IOP) settings.
