Abstract
An applicator for treatment of an elevated internal ocular pressure by means of laser radiation has a handpiece, which releasably surrounds a fiber optic light guide on its exit side end. A sleeve portion is releasably connected to the exit side end of the light guide, a condensing optical element being provided in the sleeve portion, optically dimensioned and arranged in the sleeve portion at a distance from the exit side end of the light guide such that the applied laser radiation can be focused in the ciliary body of the eye on contact of the sleeve portion with the surface of the eye.

Applicator for treatment of an elevated internal ocular pressure by means of laser radiation, comprising:
- a fiber optic light guide (2), having an exit side with an exit surface at one end,
- a sleeve portion (4, 20, 20') releasably connected to said end of said light guide (2) on said exit side,
- an optical element (21, 21') arranged on said sleeve portion (4, 20, 20') at a first distance from said exit surface of said light guide (2),
- a handpiece (1) surrounding said light guide (2) on said exit side at a second distance from said exit surface of said light guide (2), and
- manipulation of said handpiece causing adjustment of said second distance, wherein said second distance between said handpiece (1) and said exit surface of said light guide (2) is adjustable without altering said first distance between said optical element (21, 21') and said exit surface of said light guide (2).
