AIM: To discuss the reason and precautions of cornea edema after phacoemulsification(Phaco)combined intraocular lens(IOL)implantation.

METHODS: Totally 160 patients 190 eyes who underwent Phaco combined IOL implantation during 2009 to 2011 were selected. The basic information and treatment of the patients were analyzed, the cause of cornea edema after surgery was investigated and the precautions and measure were proposed.

RESULTS: Of the 190 eyes, 67 eyes appeared cornea edema after Phaco combined IOL implantation, including 25 eyes from age-related cataract patients. The incidence rate was 13.2%. 6 eyes appeared cornea edema from I and II degree nuclei patients. The incidence rate was 3.2%(6/75). 56 eyes appear cornea edema from III to V degree nuclei patients. The incidence rate was 29.5%(56/115). The records had statistical differences(P<0.05).

CONCLUSION: The reason of cornea edema after Phaco combined IOL implantation has relationship with the operation skills of the surgeons and the careful operation during the surgery is the basic of the precautions which reduce the pain of the patients and raise the success ratio of the surgery.
