OBJECTIVE To describe results in two cases of a dislocated silicone plate haptic intraocular lens managed with vitrectomy and repositioning with scleral suture fixation. METHODS Small case series. RESULTS Two patients presenting with dislocated silicone plate haptic intraocular lens underwent a 23-gauge vitrectomy with a "handshake" maneuver to pass a 9-0 prolene suture through the positioning holes to allow scleral fixation. Best-corrected visual acuity was returned to predislocation Level 2 and 8 months after the vitrectomy. CONCLUSIONS Silicone plate haptic intraocular lens can be managed with scleral suture fixation using this adapted technique, avoiding removal and exchange techniques. These are the first reported cases of silicone plate haptic intraocular lens managed with scleral suture repositioning.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D012590	Sclera	The white, opaque, fibrous, outer tunic of the eyeball, covering it entirely excepting the segment covered anteriorly by the cornea. It is essentially avascular but contains apertures for vessels, lymphatics, and nerves. It receives the tendons of insertion of the extraocular muscles and at the corneoscleral junction contains the CANAL OF SCHLEMM.

D012826	Silicone Elastomers	Polymers of silicone that are formed by crosslinking and treatment with amorphous silica to increase strength. They have properties similar to vulcanized natural rubber, in that they stretch under tension, retract rapidly, and fully recover to their original dimensions upon release. They are used in the encapsulation of surgical membranes and implants.	Elastomers, Silicone,Rubber Silicone,Silicone Rubber,Elastosil,Microfil,SE-30,Elastosils,Microfils,SE 30,SE30,Silicone Elastomer
