Objective To evaluate the clinical effects and complications of non - phacoemulsification small incision extracapsular cataract extraction(ECCE) and intraocular lens implantation to treat cataract. Methods Through 5.5 -7mm scleral tunnel incisions at 12:00, 212 cases (231 eyes) of cataracts were treated with intraocular lens implantation after continuous circular capsulorhexis and extraction of lens nucleus. Results One week postoperatively, the visual acuity was ≥0.5 in 184 eyes(79.65% ) ; one month postoperatively, the visual acuity was ≥0.5 in 202 eyes(87.45% ). The main complications were corneal edema, anterior chamber inflammation and posterior capsular rupture etc. Conclusion Nnon - phacoemulsification small incision ECCE and intraocular lens implantation is simple and has satisfied effects to treat cataract.
