• A recently developed aspiration tip and suction distributor for use in cataract surgery allow two-handed aspiration of the residual cortex lentis through the two incisions used in two-handed phacoemulsification. The instruments also facilitate removal of the cortex lentis at the 12 o'clock position, which is sometimes difficult to aspirate with an irrigation-aspiration tip only.
