Femtosecond laser-assisted cataract surgery (FLACS) putatively offers several advantages over conventional phacoemulsification. We review the current status of FLACS and discuss the evolution of femtosecond lasers in cataract surgery and the currently available femtosecond laser platforms. We summarize the outcomes of FLACS for corneal wound creation, limbal relaxing incisions, capsulotomy, and lens fragmentation. We discuss surgical planning, preoperative considerations, clinical experiences including the learning curve and postoperative outcomes with FLACS, and also the cost effectiveness of FLACS...

PURPOSE: To introduce a new sequential wavefront device with rapid sampling that can be used as an intraoperative, real-time aberrometer/refractometer for immediate diagnosis and management of refractive outcomes during cataract surgery. METHODS: A unique wavefront device uses a rotating prismatic mirror to rapidly shift the incident wavefront emanating from the eye through an aperture for analysis of a sequentially sampled wavefront segment. The sampled segment is then focused onto a quad detector that localizes its angular displacement of the sampled segment's wavefront gradient...
