[Capsulorhexis and manual extracapsular extraction].

Capsulorhexis is the best method of anterior capsulectomy. It is easier to perform a small capsulorhexis, suitable for phacoemulsification than a large capsulorhexis, suitable for a manual extracapsular extraction. We describe manoeuvres enabling the control of tearing the anterior capsule in such a way that the capsulorhexis will be adapted to the passage of the nucleus during the manual extracapsular extraction.
