AIM:To research the changes of visual acuity and astigmatism after cataract surgery with individualized incision guided by wavefront.

METHODS:We collected 104 cases with cataract and divided them into group A(69 eyes)and group B(35 eyes). Detected by TOPCON KR-1W, the corneal Polar K of the group A was <0.5 and that of the B group was >0.5. The postoperative changes of visual acuity and corneal astigmatism between two groups were observed.

RESULTS:Between the two groups, the differences of Polar K before and after surgeries at 3d, 1 and 3mo were significant(P<0.05). The Polar K of group A increased by 0.25 at 3mo after surgeries and that of group B decreased by 0.3. The visual acuity of both groups improved, and the difference was significant(P<0.05).

CONCLUSION:Individualized incision guided by Topcon KR-1W has certain correction effect for eyes with Polar K>0.5. For eyes with Polar K<0.5, there is less correction effect but raising the Polar K by 0.25.
