A Nd:YAG LASER FOR MICROSURGICAL PROCEDURES IN OPHTHALMOLOGY

A surgical laser system used in ophthalmo logy for posterior capsulotomy and pupil membranectomy (iridotomy) is presented. BIOLASER allows stereoscopic examination of eye's transparent medium and the execution of the microsurgical procedures in the anterior and posterior chambers. This paper presents also some results obt ained in order to optimize laser parameters required in medical application of BIOLASER. One of the important parameter is the specific energy for a specific application. So, for the capsulotomy operation an energy of about 3 mJ is enough and for iridotomy operation an energy of about 7-9 mJ i s necessary.
