• Complex IOL exchange Description: Patient with cataract surgery years ago elsewhere, complains of unilateral sudden drop in vision. Slit lamp examination shows what appears to be a severely inferiorly subluxated IOL - bag complex. Initial plan: sulcus suturing of patient's intraocular lens. During the operation it is incidentally found that the patient is having significant remnants of his original cataract between IOL and bag. Plan is therefore changed to IOL removal + removal of cataract fragments + anterior vitrectomy + Sulcus sutured IOL.
