We experienced 5 cases with intraocular lens (IOL) subluxation in which IOL extraction was safely conducted using two 10-0 polypropylene sutures through pars plana and proceeded with secondary IOL implantation using the same sutures. This is a report on our study of this safe method for IOL extraction and fixation method. The method is developed from ab externo sulucus fixation. Usage of two 10-0 polypropylene sutures originally placed for the second fixation enables a surgeon to hold subluxated IOL and prevents it from falling into the vitreous body cavity. A 6-mm incision is made in the corneal limbus, and the IOL is removed. Using the two 10-0 sutures that are already in place, secondary IOL implantation can be conducted at one time. There were no cases of postoperative retinal detachment. Postoperative visual acuity was improved in all cases. No dislocation was seen in any of the cases with the pupils dilated.
