AIM:To discuss clinical therapeutic effectiveness of phacoemulsification and intraocular lens(IOL) implantation on diabetic cataract patients． METHODS:Totally 80 cases (106 eyes) of diabetic cataract patients underwent phacoemulsification and foldable IOL implantation through temporal transparent cornea incision．The postoperative complications, visual acuity and incision healing were observed. RESULTS:All operations were finished successfully with primary IOL implantation in capsule.3 months after operation the naked eyesvision≤0．1 were in 6 eyes(5.7％)，0．2-0．5 in 28 eyes (26．4％ )， 0．6-1．0 in 72 eyes (67．9％)．There was no bleeding during operation and no infection after operation. CONCLUSION: It is safe and efficient to treat diabetic cataracts with phacoemulsification combined with foldable IOL implantation．
