Abstract
An ophthalmic surgical instrument (10, 10A, 10B, 10C, 10D) for use in a phacoemulsification and/or an irrigation and aspiration procedure includes an enlarged emulsification tip (20, 20A, 20B, 200, 20D) for improved capsular bag safety and enhanced efficiency. In one form, the enlarged tip (20, 200) has a pair of opposing convexly curved side walls (22, 220, 26, 260) and a flat bottom wall (28, 280) extending between the convexly curved side walls (22, 220, 26, 260). In another form, the tip (20A) has a convexly 2024/064849 curved top wall (24A) defining a first radius of curvature (r1) , an opposing flat bottom wall (28A) located between two convexly curved side walls (22A, 26A) defining a second radius of curvature (r2). In another form, the tip (20B, 20D) has a convexly curved top surface (40B, 40D) connecting to a needle shaft portion (14B, 14D) and an annular flat end face (SOD).
