AIM: To study the therapeutic effects of small incision inside the tunnel sub-nuclear techniques.

METHODS: Totally 400 cases with age-related cataract were randomly divided into experimental group(200 cases)and control group(200 cases). Small incision inside the tunnel sub-nuclear techniques was performed on the experimental group, and the control group using small incision inside the anterior chamber nuclear techniques division.

RESULTS: There were no significant differences between two groups in the postoperative visual acuityone day and one week after surgery; the incidence of complications in the experimental group was lower than that in the control group.

CONCLUSION: Small incision cataract extraction inside the tunnel sub-nuclear techniques is a safe and effective operation method, especially suitable in basic-level hospital.
