Comparaison of non-fragmentation techniques and RAPID technique

Surgical steps	RAPID technique	Traditional carouselling technique	Endocapsular carouselling technique	Phaco-rolling technique	Bowl and Snail technique
Capsulorhexis	5 mm	>5 mm	5 mm	>5 mm	≥5 mm
Hydrodissection	Done	Done	Done	Done	Done
Hydrodelineation	Not required	Required	Required	Required	Required
Sculpting	Not required	Not required	Not required	Not required	Required
Plane of phacoemulsification	Multiplanar	Supracapsular in the anterior chamber	Endocapsular	Endocapsular	Endocapsular
Special tips/instruments	None. Routine Kelman 45 degrees Kelman tip	None	Specialised 20 degrees right bent D shaped phaco-tip with a semicircular opening and a third irrigation port	None	None
Surge preventing softwares	Not required	Required	Required	Required	Required
Fluidics/vacuum	Routine	High fluidics/vacuum	High fluidics/vacuum	High fluidics/vacuum	Low Vacuum

Notes: RAPID, a soft cataract phacoemulsification technique, is an acronym-based procedure where R is rotation of nucleus, A is alignment of phacoemulsification tip sideways, P is placement of tip adjacent to the nuclear rim, I is impaling of tip into nuclear rim and D is devouring wherein nucleus is aspirated/emulsified.
