Posterior capsular opacification (PCO) is common after cataract surgery. Recurrence is very rare after a successful Yttrium aluminium-garnet (YAG) capsulotomy in adults. We report a case of visual axis re-opacification after a successful YAG capsulotomy for PCO in an adult. A 60-year male underwent phacoemulsification with +20.0 D acrylic hydrophobic intraocular lens implantation and silicon oil removal (SOR) five months after a successful retinal detachment repair. He underwent a capsulotomy after two months of surgery; however, the visual axis re-opacified after three more months. A YAG anterior hyaloidotomy resulted into improved vision which was maintained over further follow-up. In a post-vitrectomy pseudophakic eye, compression by silicon oil on the posterior capsule is lost after SOR, causing easier and faster migration of lens epithelial cells from the equator to the centre forming an early PCO. Recurrence is possible due to the proliferation of lens epithelial cells along anterior hyaloid also. This case highlights the infrequent scenario of visual axis re-opacification and therefore has teaching value for residents and trainee doctors, who should be made aware of this occurrence. Patients should be explained about this possibility when undergoing YAG capsulotomy in complicated cases such as this one.
