An ophthalmic phacoemulsification irrigation sleeve 26 includes an elongated resilient tubular body portion 28 having a distal end 30 and a proximal end 32 for surrounding a portion of a shaft of a phacoemulsification needle. An enlarged section 34 is formed on the proximal end 32 for surrounding a hub of a needle and for connection to a phacoemulsification handpiece. Adjacent to the tubular body portion distal end 30 at least one non-circular irrigation port is formed. The shape of the port includes a radiused leading edge closest to the distal end 30 and has tapering, trailing sides 40 resulting in a trailing end 42 having smaller radius than the leading edge radius. |
