Findings in pseudophakic eye that developed liquefied aftercataract-like substance one day after vitrectomy.

Purpose: To report our findings in a case that had an accumulation of a translucent fluid between the intraocular lens (IOL) and posterior lens capsule one day after vitrectomy for a vitreous hemorrhage.

Observations: A 67-year-old woman was diagnosed with diabetes 20 years before the vitrectomy and was treated with panretinal photocoagulation (PRP) for proliferative diabetic retinopathy (PDR) 14 years earlier. She underwent cataract surgery with an implantation of an IOL 4 years earlier. She was referred to our hospital because of a vitreous hemorrhage, and we performed uneventful vitrectomy. However, the day after the operation, a translucent liquid substance that resembled liquefied aftercataract was observed in the lens capsule bag. With time, the liquid substance became cloudy. The opacification progressed for two years after the vitrectomy, and her visual acuity decreased. We then performed neodymium: YAG (Nd: YAG) laser posterior capsulotomy, and the cloudy liquid dispersed into the vitreous and the visual acuity improved.

Conclusions And Importance: Our findings indicate that liquified aftercataract-like substance can form after vitrectomy in a pseudophakic eye. We suggest that the aqueous humor might flow into the space behind the IOL during or just after the vitrectomy and was trapped behind the IOL optics. Then, the proliferating lens epithelial cells might be dissolved forming the white liquid substance immediately after the surgery.
