Purpose
To compare the completeness, roundness and diameter of femtosecond laser and traditional phacoemulsification in white cataract capsulectomy.
Setting
Due to the high hardness of the lens core and the fragile capsular membrane, the traditional phacoemulsification surgery is difficult to tear the capsular and prone to complications. Femtosecond laser-assisted cataract surgery (FLACS) can accurately cut the anterior capsular membrane, improve the integrity, roundness and diameter stability of the capsular tear, and is expected to improve the surgical outcome and reduce the risk of complications.
Methods
To observe the operative effect of all white cataract. Among them, 100 performed femtosecond assisted cataract phacoemulsification and another 100 performed traditional cataract phacoemulsification.
Results
Most patients in femtosecond group obtained complete tear. Secondary capsulorhexis occurred in 10 out of 100 eyes. 3 Anterior capsular tear. In the traditional phacoemulsification group, secondary capsular tear occurred in 49 of 100 eyes and anterior capsular tear occurred in 15 of 100 eyes. The mean diameter of the lens capsule in the femtosecond group was 5.4mm, while that in the conventional phacoemulsification group was increased from 4mm to 6 mm.
Conclusions
Femtosecond laser assisted cataract surgery has high lens integrity and stable capsulorrhea diameter. Compared with traditional cataract phacoemulsification surgery, the capsular tearing time is significantly shortened, the amount of viscoelastic agent is significantly reduced, and the capsular tear diameter is more controllable.
