ABSTRACT

Objective To investigate the application value of cataract extraction surgery in the treatment of primary angle-closure glaucoma and cataract.Methods 132 patients of primary angle-closure glaucoma and cata-ract were randomly selected,these patients were divided into lensectomy treatment group(A group,n=66) and laser peripheral iridotomy treatment group(B group,n=66) according to the treatment method.The visual acuity,intraocu-lar pressure,anterior chamber depth,and complications of the two groups were analyzed statistically.Results In A group,the visual acuity 0.3-0.4 in 20 cases,>0.4 in 34 cases, accounting for 0.00%,18.18%,30.30%,51.52%.In B group,the visual acuity 0.3-0.4 in 19 cases,>0.4 in 28 cases,accounting for 7.58%,21.21%,28.79%,42.42%.A group of visual acuity 0.4 was significantly higher than B group(χ2 =7.38,P0.3-0.4 vision between the two groups were not significant(χ2 =2.71,4.61,all P>0.05). The differences of the intraocular pressure and anterior chamber depth before surgery between the two groups were not significant(t=1.532,1.447,all P>0.05),the anterior chamber depth after surgery in group A was significantly lon-ger than B group(t=2.571,P0.05).A group had corneal edema in 1 case,a transient high IOP in 4 cases,2 cases in hyphema,the postoperative complication rate was 10.61%.B group had corneal edema in 1 case,a transient high IOP in 4 cases, 2 cases in hyphema,the postoperative complication rate was 10.61%,the incidence rate of postoperative complica-tions in A group was significantly lower than B group(χ2 =9.35,P<0.05).Conclusion The application value of cataract extraction surgery in the treatment of primary angle -closure glaucoma and cataract is higher than laser peripheral iridotomy,which can more effectively improve visual acuity, prolong anterior chamber depth, reduce inci-dence of complications of patients,so it is more safe and effective,and worthy of promotion.
