Ophthalmic surgical instrument for insertion into the eye comprising: an instrument handle (10 ’)； a rigid tubular sleeve (20 ') protruding from the handle (10') to a distal end (22 ') of the sleeve, the distal end of the sleeve (22') being sized for insertion of the distal end of the sleeve (22 ') inside an eye, an optical fiber (60) that extends through the handle (10 ') and the sleeve (20') to a distal end portion (66) of the fiber, in which the portion of distal end (66) of the optical fiber (60) is contained in a tubular tip (70) having a previously bent portion and is made of a shape memory material, the tubular tip (70) being stationary fixed to the optical fiber (60)； and characterized by the fact that said rigid tubular sleeve is stationary fixed to the handle, and a mechanism (80) in the handle (10 ') and connected to the optical fiber (60) to selectively displace the optical fiber ( 60) between a position pushed forward of the optical fiber (60) in which the optical fiber (60) protrudes a first distance from the handle (10 ') so that the distal end portion (66) of the optical fiber ( 60) protrudes from the sleeve (20 ') to cause the optical fiber (60) to bend and a rearward position of the optical fiber (60) in which the optical fiber (60) protrudes a second distance from the handle (10 ') which is smaller than the first distance so that the distal end portion (66) of the optical fiber (60) is contained in the sleeve (20') to cause the optical fiber (60) to straighten.Instrumento quirúrgico oftálmico para la inserción en el ojo que comprende: un mango de instrumento (10&rsquo；)； un manguito tubular rígido (20&rsquo；) que sobresale del mango (10&rsquo；) hasta un extremo distal (22&rsquo；) del manguito, estando el extremo distal del manguito (22&rsquo；) dimensionado para la inserción del extremo distal del manguito (22&rsquo；) en el interior de un ojo, una fibra óptica (60) que se extiende a través del mango (10&rsquo；) y el manguito (20&rsquo；) hasta una p
