Bimanual phacoemulsification has been a potential technique for a number of years, but only recently have the technology, software, and technique advanced sufficiently to make bimanual phacoemulsification a feasible method of cataract extraction. Although the main disadvantage to bimanual phacoemulsification remains the lack of intraocular lenses that can fit through microincisions, necessitating the enlargement of corneal wounds for intraocular lens implantation, bimanual phacoemulsification has a number of advantages over traditional small-incision phacoemulsification. Theses advantages have been a source of interest for cataract surgeons and surgical companies who are now developing technologies that will permit the performance of truly microincisional cataract surgery.
