Surgical technical note: Evisceration using the Russian-doll technique and the parachute technique

The authors describe a new technique of evisceration after resection of the corneal epithelium and limbus, with preservation of the posterior layer of the cornea and anterior sclera, after a 360° dissection of the sclera behind the insertion of the oculomotor rectus muscles, and preservation of the insertions of the rectus muscles. The technique is designated “Parachute” when the posterior sclera is excised, and “Russian doll” when the posterior sclera is preserved and is behind the orbital implant. The implant is inserted at the end of the procedure with a “birdcage” forceps. The indications of these techniques are those of conventional evisceration when the size of the globe remaining is at least a third of the volume of a normal eye.
