title: Dislocated posterior chamber intraocular lens scleral fixation technique through 23-gauge vitrectomy cannulas.
abstract: A scleral fixation technique for posterior dislocated intraocular lens performed through 23-gauge vitrectomy cannulas is presented. It is based on the creation of polypropylene loops at opposite meridians through which haptics are engaged and placed in the sulcus. Repositioning of the intraocular lens (as opposed to substitution that requires new or reopening of corneal incisions) associated with microincisional vitrectomy techniques (23 gauge) allows for faster patient recovery. Free rotation of haptics through the loops aids in providing spontaneous good intraocular lens centering. The technique provides a minimally invasive solution for dislocated intraocular lenses after the unavoidable vitrectomy procedure to liberate the lens from the vitreous chamber.
