AIM: To investigate the application of small incision non-phacoemulsification to construct 9 o'clock range of auxiliary incision in the primary prevention of blindness.

METHODS: Totally, 160 cataract patients(160 eyes)were randomly divided into the observation group(85 cases, 85 eyes)that were constructed 9 o'clock range of auxiliary incision in small incision non-phacoemulsification and the control group(75 cases, 75 eyes)that was operated the traditional manual sutureless in small incision non-phacoemulsification. The operation time of postoperative astigmatism and postoperative visual acuity between the control group and the observation group were compared.

RESULTS: There were statistical significance in visual acuity and the operation astigmatism at 1,2wk,1,3mo(P<0.05).

CONCLUSION:To control 9 o'clock range of auxiliary incision in small incision non-phacoemulsification reduces the operation of postoperative astigmatism and restore good eyesight at the same time, it has certain practicability and effectiveness.
