Abstract
The authors describe a bimanual double aspiration/single irrigation system (DASIS) for cataract surgery that efficiently and safely performs aspiration of the entire cortex, including subincisional space. DASIS uses standard and common instruments such as an irrigation/aspiration handpiece in one hand and a single-aspiration handpiece in the other, joined with a short silicone tube using a three-way stopcock. DASIS allows access to 360° of the cortex without a hand exchange, reducing wound leakage and maintaining chamber stability.
