Interlenticular opacification of piggyback acrylic intraocular lenses

A dense interlenticular opacification developed 18 months after cataract surgery in a hyperopic patient with 2 acrylic piggyback intraocular lenses (IOLs) placed in the capsular bag. The patient developed a hyperopic shift with decreased vision, requiring explantation of the lenses. The dense interlenticular opacification did not allow separation of the lenses intraoperatively because of the tight adherence of the 2 IOLs.
