[Original technique of double capsulorhexis].
The current endophako technique with posterior scleral tunnel incision requires perfect continuous curvi-linear capsulorhexis. A rupture in the capsulorhexis ring may produce a posterior capsular tear. An excessively large anterior capsular residue will lead to purse-string fibrosis. The original surgical technique of double circular capsulorhexis resolve these two points. This technique allows a small capsulorhexis (diameter about 4 millimeters), reproductibility in spite of difficult surgical cases (hypertonia, poor visibility); it avoids tearing the anterior capsular edge to the zonula. A second capsulorhexis at the end of the operation, exactly following the optic zone of the intra-ocular implant, helps to guide healing of the anterior capsular edge, reducing fibrosis and avoiding purse-string fibrosis. The double capsulorhexis technique allows a double security: during surgery: it ensures a safe reproducible capsulorhexis; after surgery: the guided ablation of the large anterior capsular residue allows better long-term retinal follow up.
