AIM: To observe the middle and long-term visual function in patients after free recommended cataract surgery by the CDPF organization.

METHODS:Totally 2000 cases 2 278 eyes from August 2005 to June 2011 in our hospital after cataract surgery were retrospectively analyzed. The patients were followed up for 3 months to 3 years. The vision, after-cataract and the fundus condition were recorded.

RESULTS: The last postoperative follow-up: the best-corrected visual acuity was≥0.05 in 2 257 eyes(visual recovery rate 99.08%); ≥0.3 in 2 098 eyes(the demaimed rate 92.10%). During follow-up visual acuity decreased in 392 eyes, of which after-cataract was in 278 eyes, fundus disease in 107 eyes, postoperative delayed uveitis in 5 eyes, ocular trauma in 2 eyes.

CONCLUSION: Corneal astigmatism after cataract surgery, after-cataract and fundus disease are main reasons of visual function damage. Postoperative delayed uveitis is worth paying more attention. In poor and backward area, the ophthalmologists should also publicize the related prevention and control knowledge to patients with diabetes and hypertension.
