Purpose:To present our experiences in the management of intraocular lenses(IOLs)dislocated into the vitreous cavity through 1.5mm corneal incisions without pars plana vitrectomy or sclerostomy.

Method:A repositioning and suturing technique was performed for a posteriorly dislocation IOL from the middle vitreous cavity.The anterior vitreous body is removed in two steps through 1.5mm corneal incisions，the dislocated IOL is retrieved through corneal incisions，the haptics are externalized for tying knots and then directly sutured for scleral fixation.

Results:Best corrected postoperative visual acuity was 20/20.the IOL was well centered，and no significant complications were observed.

Conclusion:Without pars plana vitrectomy or sclerostomy，this new technique minimizes intraoperative maneuvers，reduces the complications，and offers a simple，effective repositioning and suturing method of posteriorly dislocated IOLs.
