Abstract
A system and method are provided for obviating Posterior Capsule Opacification (PCO) which require an Optical Coherence Tomography (OCT) device for imaging the interface surface between the posterior surface of an intraocular lens (IOL) and the capsular bag. Further, the OCT device is used to identify areas of relative opacity caused by a biological growth on the interface surface in the optical zone of the IOL. A laser unit is then used to direct the focal point of a femtosecond laser beam onto the areas of relative opacity to ablate the biological growth by Laser Induced Optical Breakdown (LIOB) to thereby obviate the PCO.
