Glued IOL
Glued IOL or Glued Intraocular lens is a new Surgical technique for implantation of a posterior chamber IOL with the use of biological glue in eyes with deficient or absent posterior capsules (Fig 1). A quick-acting surgical fibrin sealant derived from human blood plasma, with both hemostatic and adhesive properties is used.
