Abstract

A method for treating presbyopia of a crystalline lens using a femtosecond laser system, operated in a parameter regime characterized by extremely short pulse duration (below 100 fs) and low pulse energy (sub-μJ) of the pulses delivered to the lens tissue. The laser beam has a small focal volume in the tissue that is achieved by the short spatial pulse length, rather than defined by the large depth of focus resulting from the low numerical aperture of the laser beam. The laser energy density within the small focal volume (below 50 μm) is sufficiently high to induce optical breakdown of the tissue, which reduces the Young's modulus of the lens to improve accommodation, thereby reducing presbyopia. Meanwhile, the total pulse energy in the focal volume is sufficiently low, resulting in small cavitation bubbles, which reduce light scattering and other damage or undesirable effects in the treated lens tissue.
