摘要
A lens holding ring 50 is held by a string-like body 40a stretched along a surface of an eyeball 1 by being supported by a plurality of cannulas 21, 22 inserted to a sclera 2, and is fixed to the surface of the eyeball 1 by a tensile stress of the string-like body 40a, and in this state, holds a surgery lens 30 on the eyeball. The lens holding ring 50 comprises a lens holder 51 including an opening 52 into which a lens is inserted, and engagement parts 57 provided at positions opposed to each other across the opening 52. Each engagement part has an engagement structure of engaging with the string-like body 40a for fixing the lens holder to the surface of the eyeball so as to interpose the lens holder therein, and has a folded part 58 on the tip of the engagement part for preventing coming-off of the string-like body.
