Femtosecond laser–assisted intraocular lens exchange

Intraocular lens (IOL) exchange in patients with anterior capsule contraction resulting from phimosis can complicate IOL exchange as the fibrotic anterior capsule must be cut to gain access to the IOL. Maintaining curvilinear capsulotomy is particularly important when the desired outcome is bag-to-bag IOL exchange. Similarly, when the posterior capsule is open, properly sized curvilinear anterior capsulotomy will allow for optic capture and further stability of the exchanged IOL. Secondary capsulotomy size ranged from 4.9 to 5.0 mm, and the energy was set at 4 to 10 μJ depending on diffusiveness of the anterior capsule. The femtosecond laser was adapted to create a secondary anterior capsulotomy to facilitate IOL exchange.
