A 65-year-old male patient presented with hand movements in right eye for past 6 months. On examination, undilated right eye (RE) looked like a hypermature absorbed cataract [Figure 1]. He gave a history of lens exchange procedure in RE 3 years back. In B scan, we found intraocular lens (IOL) reverberation and in IOL master 700, lens thickness was less and anterior chamber depth was deep, indicating opacified IOL in anterior segment optical coherence tomography (AS OCT) [Figure 2]. IOL formula used here is SRK-T formula in pseudophakic mode, which is quite accurate in calculations with axial length and keratometer reading in such situations. IOL exchange was done and in-the-bag IOL was placed and vision improved to 6/9p [Figure 3]. Opacified IOL is a rare late postoperative complication after an uneventful phacoemulsification surgery occurring in a hydrophilic lens., This often mimics a mature cataract or posterior capsular opacification. This emphasizes careful slit-lamp examination with other routine investigation like B scan and A scan to clinch the diagnosis and prevent intraoperative surprises. The most challenging complication during IOL exchange is the adhesion of IOL to the capsule and while removing, zonular dehiscence and posterior capsule rupture occur which compromises the placement of secondary IOL in the bag.
