Study Summary
The purpose of this research study is to evaluate the clinical outcomes of the use of low-energy segment removal with a micro-interventional irrigation/aspiration port (MICOR-304) to evacuate the lens prior to intraocular lens insertion in subjects undergoing routine cataract surgery.
Primary Outcome
Total lens removal time is defined in two phases: * The beginning time starts when the surgeon enters the eye with the MICOR-304 to start the lens removal process and completing when the surgeon finishes the nucleus lens removal with the MICOR-304 before changing over to irrigation and aspiration. * The second phase of lens removal time is the irrigation and aspiration stage for cortex removal which starts when the irrigation and aspiration tip enters the eye and completion time is when the cor
