摘要:
A laser system for changing the index of refraction of cornea tissue in a living eye. The laser system comprises a laser that provides laser pulses with a wavelength from 400 nm to 900 nm and a pulse energy from 0.01 nJ to 10 nJ, and a control device for setting the operating parameters of the laser below an optical breakdown threshold of the tissue to avoid photo-disruption and tissue destruction of the tissue, and to direct the laser pulses at the cornea tissue resulting in a change in the index of refraction of the tissue within regions irradiated by the laser pulses.
