Cataract Extraction Categories.
Canadian Medical Guide Definition Capsulorhexis - The making of a continuous circular tear in the anterior capsule during cataract surgery in order to allow expression or phacoemulsification of the nucleus of the lens. (Dorland, 28th ed)
Canadian Medical Guide Definition Phacoemulsification - A procedure for removal of the crystalline lens in cataract surgery in which an anterior capsulectomy is performed by means of a needle inserted through a small incision at the temporal limbus, allowing the lens contents to fall through the dilated pupil into the anterior chamber where they are broken up by the use of ultrasound and aspirated out of the eye through the incision. The small incision allows the surgeon to use very few or even no stitches to close the tiny wound. There is usually no need for hospitalization and patients may resume most activities within days. (Cline, et al., Dictionary of Visual Science, 4th ed & In Focus 1993;1(1):1)
