Abstract：Objective To observe the therapeutic effects of small incision non -phacoemulsification extracapsular cataract extraction on cataract in the elderly .Methods Fifty elderly patients with cataract who were admitted and treated in our hospital from March 2014 to March 2016 in our hospital were randomly divided into trial group ( n =25 ) and control group ( n =25).The patients in control group were treated by phacoemulsification ,however,the patients in trial group were treated by small incision non-phacoemulsification extracapsular cataract extraction .The visual acuity before and after surgery, astigmatism,intraocular pressure, corneal endothelial cells and postoperative complications were observed and compared between two groups.Results After surgery,visual acuity of patients was obviously improved in both groups ,as compared with that before surgery,moreover, the visual acuity of patients on 3d after surgery in trial group was superior to that in control group ( P <0.05).The astigmatism status of patients was obviously improved on 3d,1m after surgery in both groups,as compared with that before surgery ( P <0.05).The cell density and proportion of hexagonal cells after operation were significantly decreased in both groups ,as compared with those before operation ,moreover, the decrease extent in control group was more obvious than that in trial group ( P <0.05).On 12h and 24h after surgery, the intraocular pressure was significantly improved,as compared with that before surgery ( P <0.05).The incidence rate of adverse reactions in trial group was 16%,which was significantly lower than that (52%) in control group ( P <0.05).Conclusion The therapeutic effects of small incision non -phacoemulsification extracapsular cataract extraction on cataract in the elderly are suprior to those by phacoemulsification,which can effectively improve patient 's visual acuity, astigmatism and intraocular pressure,with safety and fewer complications .
