Surgical techniques for giant retinal tears with retinal tacks

In order to repair an inverted retinal flap on the choroid in case of retinal detachment with giant tears, the authors have developed a retinal tack made of acetalcopolymerisate. The tack is very durable and should remain inactive in the human body, owing to its stability under conditions of heat, alkali and acid. Manipulating the tack is adequately easy; the procedure and the tacks themselves appear to be well tolerated by the eye. The detailed design of the tack and its method of use are described in this report.
