Comparison of femtosecond laser LenSAR and LenSx combined with extracapsular cataract extraction in treatment of elderly cataract patients
[Objective]To compare the efficacy of femtosecond laser LenSAR and LenSx combined with extracapsular cataract extraction in the treatment of elderly cataract patients,in order to provide evidence for clinical improvement of treatment.[Methods]A total of 96 elderly cataract patients admitted to Yongmei Group General Hospital from April 2021 to March 2023 were prospectively selected as research objects and divided into SAR group and Sx group according to random drawing method,with 48 cases in each group.Extracapsular cataract extraction was performed in both groups.The SAR group was treated with femtosecond laser LenSAR,and the Sx group was treated with femtosecond laser LenSx.Perioperative indexes,intraocular pressure before and after surgery,and incidence of complications were statistically compared between the two groups.[Results]The anterior capsule incision time,docking attempt times,pre-nucleus splitting time and laser emission time in SAR group were shorter than those in Sx group,and the negative pressure attracting time was longer than that in Sx group(P<0.05).After operation,IOP in both groups was higher than that before operation,and the increase of IOP in SAR group was higher than that in Sx group(P<0.05).Compared with 27.08%in Sx group,the complication rate in SAR group was significantly decreased by 8.33%(P<0.05).[Conclusion]Femtosecond laser LenSAR and LenSx combined with extracapsular cataract extraction have different effects in the treatment of elderly cataract patients.LenSAR is convenient for interface docking and has less complications,while LenSx effectively controls IOP and reduces total negative pressure attracting time.
