Abstract：Objective To evaluate the feasibility,efficacy,and safety of phacoemulsification cataract extrac-tion as a high-efficiency vision restoration solution in the context of disaster relief.Methods A retrospective co-hort study was conducted,consecutively enrolling 835 patients who underwent phacoemulsification cataract surgery at Fuzhou Second General Hospital between February 11,2022,and February 11,2024.Preoperative and 1-month postoperative parameters,including visual acuity,corneal astigmatism,intraocular pressure,corneal endothelial cell density,and the incidence of complications,were compared and analyzed.Results At 1 month postoperatively,patients exhibited a highly significant improvement in uncorrected distance visual acuity,best-corrected distance visual acuity,uncorrected near visual acuity,and best-corrected near visual acuity compared to preoperative levels(P＜0.001).The mean corneal astigmatism and surgically induced astigmatism decreased significantly(P＜0.001).IOP at 1 month post-surgery was significantly lower than the preoperative value(P＜0.001),while the corneal ECD showed no significant loss compared to the preoperative count(P＞0.05).The overall incidence of complications was only 1.44％(12/835).Conclusion Phacoemulsification enables rapid and significant visual recovery in cata-ract patients,demonstrates excellent postoperative refractive stability,and exhibits a high safety profile.Its charac-teristics of high efficiency and postoperative stability align well with the core requirements for technical solutions in disaster medical,making it an ideal choice for batch vision-restoration surgery following disasters.
