Abstract

We present our first experimental results of lens irradiation obtained with ultrashort pulse lasers. The irradiation was done with the Ti:Safire laser which irradiates at 800 nm with a repetition rate of 76 MHz. The maximum average intensity used was 300mW, with pulses of 4 nJ. The holographic images obtained have given us information about the focusing process of the lens capsule as well as its rupture, thus indicating the level of penetration in the lens and capsule rupture. The results obtained in these first experiments allow us to establish protocols and techniques to break the capsule of the lenses as well as to carry out possible modifications inside the lens. As the optical system developed works in real time, it is possible to perform dosimetry measurements in the light-lens interaction processes giving quantitative information about the breakdown of the tissue structures. In future projects the possible side effects of thermal action and local modification of the capsule will be analyzed; these are important aspects in the field of noninvasive lens surgery.
