Optimising phacodynamics is an extremely important aspect of cataract surgery but less importance is given to understanding and applying this knowledge. Inappropriate phaco parameters will lead to wound burn, iris shaffing, progressive intraoperative miosis, damage to corneal endothelium and macula. Increased fluid consumption intraoperative turbulence plays a role in postoperative inflammation by increasing prostaglandin release. The incidence of post-occlusion surge will also be minimised by judicious use of phaco parameters. Optimising active fluidics for special situations like high axial myopia, posterior polars, IFIS, small pupil and hard cataracts are demonstrated in this video. Various applications of active fluidics like patient eye level, irrigation factor, IOP ramp and balanced energy tip are depicted in the above said scenarios to perform a complication free cataract surgery.
