Abstract:

Femtosecond laser-assisted cataract surgery  is mainly used in four key-procedures including anterior capsulotomy，lens fragmentation，clear corneal incision and limbal relaxing incision creation. A number of studies have proved the advantages of this new technology compared with traditional cataract surgery,  but we also cannot ignore its intraoperative complications in the early use and its impact on operation, including suction break,  conjunctival redness or hemorrhage,  capsular blockage syndrome,  posterior capsular ruptures,  anterior radial tears, and miosis. Most of which can be reduced or even avoided by strengthening preoperative education and intraoperative guidance,  increasing the proficiency of surgical technique and equipment updates. However,  the specific mechanisms of myosis is unclear,  further studies are needed.
