Abstract Purpose: To report the correlation between lens movement during continuous curvilinear capsulorrhexis(CCC)and the findings of the anterior capsule striae during CCC and capsule ovaling after intraocular lens(IOL)implantation.

Material and methods: This study was made 224 eyes that underwent phacoemulsification(PEA)and IOL implantation. We classified the zonular weakness into 4 grade based on lens movement during CCC:grade normal(N), weak(W), very weak(VW), and extremely weak(EW). We examined the presence of anterior capsule striae and capsulprhexis ovaling in each grade.

Results: We classified 158 eyes as grade N, 44 eyes as grade W, 20 eyes as grade VW, and 2 eyes and grade EW. The finding of anterior capsule striae and capsulorhexis ovaling was more frequent as the zonular weakened.

Conclusion: There is a possibility that lens movement during CCC, anterior capsule striae and capsulprhexis ovaling may be useful signs of zonular weakness.
