WebDec 29, 2024 · In this large, prospective longitudinal case series study, the four-year follow-up data demonstrated that compared to ciliary sulcus secondary IOL implantation, in-the-bag IOL implantation yielded smaller PE. An appropriate IOL power adjustment for ciliary sulcus secondary IOL implantation should be made to counter the change in PE.

WebPlacing an IOL in the bag when the posterior capsule has ruptured may also trigger extension of the tear and lead to IOL instability, especially if the capsular defect is large and/or irregular. A ruptured posterior capsule is a common indication for sulcus IOL implantation provided that anterior capsular support is sufficient.
