Abstract
A system and method of replacing a lens to treat a cataract is disclosed. Cataractous tissue is ablated via a multi-photon process using focused, ultra-short laser pulses. Multi-photon ablation requires an energy intensity between 10to 10W/cm. Using lasers having femto-second duration pulses, this intensity is achieved with 50 micro-Joules of energy, allowing material disruption with very little heating or shock. The multi-photon ablated material is removed through a micro-channel that leads from the multi-photon ablated region to at least the surface of the eye. Once the material is removed a pre-polymer fluid is injected in to fill the void. This polymerizes into a gel once inside the lens. The polymerized, transformed material matches both the transparency to visible light and the Young's modulus of healthy lens.
