Successful surgical management of interlenticular membrane by vitreoretinal interlenticular membranectomy (VIM)


The formation of a light scattering interlenticular membrane (ILM) is a known complication of polypseudophakia and has been particularly noted with the use of dual intracapsular Alcon AcrylSof intraocular lenses (IOLs). The treatment options for this condition have largely been restricted to either Nd:YAG laser membranotomy or explantation of the dual IOL complex. In this case report, we describe an unusual case of ILM in a 76-year-old woman whose ILM had formed between her primary intracapsular IOL and her piggyback sulcal IOL. Furthermore, we describe vitreoretinal interlenticular membranectomy (VIM), a novel technique involving a translimbal anterior interlenticular membranectomy using vitreoretinal instrumentation. There were no intraoperative or postoperative complications. Postoperative best-corrected visual acuity was 6/4, maintained for 3 years of follow-up. VIM is offered as a management option for surgeons to address ILM when Nd:YAG laser therapy fails, and the IOLs cannot be safely explanted.
