To describe clinical and post-mortem results after bag-in-the-lens (BIL) implantation which lens offers a centration not capsular based but surgeon-controlled.
The BIL implantation technique is primarily designed to avoid PCO but in addition includes a very important surgical degree of freedom consisting in the alignment of the BIL using the Purkinje reflexes of the light sources of the surgical microscope (surgical axis of alignment).
Based on the very encouraging clinical and post-mortem images (MRI and histology) a new surgical device is proposed to help the surgeon to improve the centration by centering a caliper ring, used for the sizing of the anterior capsulorhexis, along the first Purkinje reflexes of the light sources of the microscope.
Surgeon-controlled BIL centration is a new approach of IOL centration which method of centration aims at optimizing patient’s quality of vision, more specifically when implementing toric, aspherical or multifocal correction in the IOL optic.
