AIM: To evaluate the reliability of preoperative examination for predicted visual acuity and visual function of the cataract eyes before phacoemulsification combined with intraocular lens(IOL)implantation.

METHODS: A total of 83 cases(83 eyes)of cataract were selected from those who underwent phacoemulsification combined with IOL implantation in our hospital. Data were collected for the correlation of preoperative examination with postoperative visual acuity and visual function index scale(VF-14).

RESULTS: Age, sex, eye axis, nuclear hardness, preoperative vision, cataract type, hypertension history, diabetes history, the contralateral vision and sicken time had correlation with postoperative VF-14 and vision; Regarding the VF-14, the predictive factors were the preoperative VF-14, diabetes history and the eye with the better vision. The predictive value was about 83.5%.

CONCLUSION: The postoperative visual acuity and visual function can be evaluated by basic data.
