A 56-year-old male presented with defective vision in both eyes for 6 months. He is known case of diabetes for 7 years, history of left eye cataract surgery 5 years back, retinal surgery for proliferative diabetic retinopathy 4 years back and history of Yag capsulotomy in left eye 2 years back for posterior capsular opacification (PCO). Vision in right eye is 6/12 and left eye 6/24. On examination, right eye showed lens changes, and left eye showed pseudophakia with well-circumscribed Yag opening in the centre [Figure 1a] with opacified white fibrotic matter on the anterior hyaloid phase covering the yag opening [Figure 1b]. Both eye fundi showed stable proliferative diabetic retinopathy. Repeat yag capsulotomy enlargement with hyaloidotomy was done, and the vision is improved to 6/9.

Recurrence of after cataract (PCO) is very rare occurrence after Nd-Yag capsulotomy with large opening.[1] Postoperative inflammation causes elevated cytokines which leads to lens epithelial cell (LEC) proliferation beyond the margin of capsulorhexis.[2] LECs can also proliferate along intact anterior hyaloid phase.[3] Most common cause for recurrent PCO is post-vitrectomized eyes undergoing cataract surgery especially for diabetic retinopathy, complicated cataract and myotonic dystrophy.[2,4] Treatment includes repeat Nd-yag capsulotomy and Nd-yag anterior hyaloidotomy if PCO proliferates along the anterior hyaloid phase. So in such patients should explain the possibility of recurrent PCO.
