This poster demonstrate the surgical approach of patient with posterior dislocated intraocular lens (IOL), who underwent pars plana vitrectomy (PPV) with anterior iris claw implantation.
Centro Hospitalar e Universitário de Coimbra - Hospital Geral, ophthalmology Department
The surgery was performed under peribulbar anesthesia. Standard 20-gauge three-port PPV was performed and IOL was removed with vitreous forceps to a limbal incision. Two ports were closed with 7-0 vicryl suture with the infusion cannula in place. Intracameral pilocarpine was used to constrict the pupil. Two paracentesis were made. Iris claw IOL was inserted and rotated into horizontal position.. At the same time, through paracentesis, an IOL dialer was introduced and the iris was enclaved by applying gentle pressure over it through the slotted center of the lens haptic. A similar maneuver was then repeated on the other side. Corneal tunnel was closed with a 10-0 ethylon suture. The pars plana infusion cannula was removed and the port was closed with a 7-0 vicryl suture. Conjunctival closure was done with a 7-0 vicryl suture.
After a 6 months follow-up for, the postoperative best-corrected visual acuity (BCVA) was 20/40, without any complications.
Iris claw IOL implantation is clinically safe and effective to correct aphakia when combined with PPV for posterior dislocated IOL without capsular support.
