3146 Concentration of vancomycin in irrigating solutions for cataract surgery

Purpose: Capsular related complications may occur during and/or following cataract s”rPew. Methods: We used endocapsular PUMA rings (EPR) to prevent such complications in eyes with pre or peroperative zonular c’ehiscence, high myopic eyes and eyes witl: exfoliation syndrome which have weak zonoles. EPR can be implanted easily through the phaco-incision before aspiration of the cortex or just before the injection of a foldable IOL. Results: The advantages of EPR are : to stabilize the bag ; to prevent the asymetrical retraction of the bag and thus prevents foldable IOL decentration : prevents the retraction of the anterior capsule observed with small capsulorhexis. More over EPR may provide a better quality of the vision by eliminating folds and wrinckles in the capsule and may delay the proliferation of lens epithelial cells and posterior capsule opacification in combination with antimetabolite drugs. Conclusion: The combination of rigid EPR with foldable IOL may represent a very safe surgical option to prevent capsular complications.
