Trocar-assisted, flanged sutureless scleral-fixated intraocular lens implantation combined with silicone oil injection after penetrating keratoplasty surgery.

We describe a combined technique of trocar-assisted sutureless scleral-fixated intraocular lens implantation and silicone oil injection at the same session. Two 3 mm scleral tunnels were created 2 mm away from and parallel to the limbus with the 23-gauge vitrectomy trocars entering the sclera transconjunctivally at an angle of approximately 10° at the 3 o'clock and 9 o'clock meridians. After the 3-piece foldable IOL was delivered to the anterior chamber through the corneal incision, the tip of one of the IOL haptics was grasped with a 23-gauge serrated retinal forceps entered through the trocar located at the 3 o'clock meridian. Then the haptic was removed from the scleral tunnel together with the trocar out of the globe. The same procedure was applied to the other haptic. A transconjunctival secure 10-0 nylon suture was placed at the scleral tunnel entry site around the haptic. The ends of the haptics were cauterized to make a flange. The resultant flanges of the haptics were pushed back and fixed into the scleral tunnels. Perfluorooctane was taken out of the eye with vitreoretinal surgery and the silicone was injected into the eye to prevent hypotonia. No complications were seen intraoperatively or postoperatively. After 1-month follow-up period, IOL was seen stabilized.
