AIM: To report the safety and effectiveness of LenSx femtosecond laser-assisted cataract surgery.

METHODS: Sixty-seven patients(76 eyes)were included in the study. All the cases underwent LenSx femtosecond laser-assisted cataract surgery between Jul. 2014 and Jul. 2015. The completion rate of anterior capsulotomy, lens fragmentation, intraocular lens implantation and corneal incisions, the best corrected distance visual acuity(CDVA)before and 1mo after femtosecond laser-assisted cataract surgery, the adverse events and equipment defect rate were recorded. The regression analysis of possible factors affecting the completion rate of corneal incision(eye, age, location of incision, corneal diameter, peripheral corneal thickness, preoperative corneal astigmatism)was taken.

RESULTS: All surgeries were uneventful. The completion rate of anterior capsulotomy, lens fragmentation, intraocular lens implantation and corneal incisions was 97%, 100%, 100% and 83%, respectively. No adverse events(posterior capsule rupture, corneal edema, macular edema and retinal detachment)and device defect occurred. The CDVA was significantly improved 1mo after surgery. Logistic regression analysis showed that there was a correlation between location of corneal incision and completion rate of corneal incision, and no correlation was found between eye, age, corneal diameter, peripheral corneal thickness, preoperative corneal and completion rate of corneal incision.

CONCLUSION: The LenSx femtosecond laser-assisted methodis efficient and safe for cataract surgery.
