Introduction The aim of this study was to report a technique for the removal of dislocated polymethyl methacrylate (PMMA) intraocular lenses (IOLs) in glaucomatous eyes. Methods Dislocated PMMA IOLs were removed from the inferior sclerocorneal incision, and sutureless intrascleral fixation of each IOL was performed to preserve the intact superior conjunctiva and sclera for future trabeculectomy or to maintain a functional filtering bleb of trabeculectomy. Results In two cases, the condition of the bleb did not change, while the intraocular pressure improved or did not change after the procedures. IOL fixation was stable with no complications, such as tilt, decentration, or extrication of the IOL haptics. Conclusion This procedure of preserving the superior conjunctiva and sclera can maintain the function of the bleb, superior cornea and sclera and may contribute to the success of future trabeculectomy.
