Trocar-assisted intrascleral sutureless fixation of a dislocated three-piece sulcus intraocular lens

ABSTRACT Trocar-assisted intraocular lens (IOL) reposition surgery using a scleral fixation method was performed for a patient with a dislocated sulcus IOL. Two 3-mm-long scleral tunnels 2 mm from and parallel to the limbus were formed using a 23-gauge vitrectomy trocar transconjunctivally entering the sclera at an angle of approximately 10 °. Haptics were collected using a 23-gauge serrated retinal forceps entering from the trocar cannula and externalized from the scleral tunnels together with the trocar. The same procedure was applied for the other haptic. Both haptics were pushed into the scleral tunnel and a transconjunctival secu re 10-0 nylon suture was placed at the scleral tunnel entry site around the haptic. Sutures were removed 1 week later. No complications occurred intraoperatively or postoperatively. At a 10-month follow-up, IOL was stabilized. IOL reposition surgery using the trocar-assisted IOL scleral fixation met hod is a viable alternative to intrascleral fixation surgery.RESUMO Relatamos uma cirurgia de reposi ção de lentes intraoculares (LIO) usando o método de fixação escleral de lentes intraoculares usando o trocarte em paciente com lentes intraoculares deslocada no sulco.
