Abstract
A summary of using near (Nd) and middle (Er) infrared YAG laser systems in ophthalmology surgery is given in the paper. The report on twelve years of clinical experience with the ophthalmic Nd:YAG laser system (λ=1.06 μm) operating alternatively on Q-switched or mode-locked regimes is accomplished. From statistical data processing of more than 1000 interventions it follows that better results in a posterior capsule opacification cure are achieved with the use of short, near-infrared mode-locked 25 ps long pulses, while 4 ns long giant pulses of the same wavelength are useful for iridectomy creations. Middle infrared radiation generated by the Er:YAG laser system (λ-2.94 μm) was used for pre-clinical interaction experiments (in vitro). Differences in results of cornea, lens and sclera ablation by a free running (110 μs long) and Q-switched (250 ns long) mid-infrared pulses are presented. The radiation was delivered to the interaction place either by a system of reflected mirrors (used for Nd:YAG laser), or by a special sealed waveguide (in the case of Er:YAG system).
