A patient with bilateral cataracta membranacea

A 56-years-old man with good medical health presented with bilateral blurring of vision over 10 years. Slitlamp examination revealed a bilateral cataracta membranacea mainly on the periphery, but involving his visual axes. Cataract extraction and intraocular lens implantation were performed on both eyes. Anterior capsules were not intact in both eyes preoperatively. Anterior vitrectomy was performed in the left eye in view of posterior capsule rupture intraoperatively. Intraocular lens were inserted in sulcus in the left eye and in the bag in the right eye. Postoperatively, his visual acuity improved in both eyes but only moderately. The indication, timing of surgery and the surgical techniques will be discussed
