ABSTRACT
Requirements for cataract surgery have gradually increased from the original rehabilitation procedure to personalized refraction surgery.Femtosecond laser-assisted cataract surgery is being widely used because of its precision of incision,accuracy of capsule cutting and high efficiency of nuclear fracturing in recent year.Currently some operating systems of femtosecond laser-assisted cataract surgery include LenSx,Catalys,LenSAR and Victus,and they are different in the design of contact interfaces,video and operating bed and therefore present different working methods.Ophthalmologists should be aware of the differences of these operating systems and accurate assess the clinical findings of patients in order to consider the preciseness,accuracy,efficiency of incision,capsulorhexis and nucleus fragmentation to avoid the intraoperative and postoperative complications.
