Abstract. A 85-year-old man received bilateral cataract surgery with implantation of hydrogel intraocular lens(IOL). His visual acuity improved to 1.2 in either eye. Eighteen months later,the visual acuity decreased to 0.6 in either eye due to aftercataract. Both eyes were treated with 27 shots of Nd:YAG laser to create a circular opening. The visual acuity improved to 1.0 right and 1.2 left. Another 6 months later,his left visual acuity decreased to 0.3. A semi-opaque membrane had formed on the posterior surface of IOL. The membrane was separated from the anterior vitreous. Laser capsulotomy induced improvement of vision to 1.2. The right eye had full visual acuity,but the lens epithelial cells had started to proliferate and migrate centrally from the edge of capsulotomy opening. It appeared that laser capsulotomy released the epithelial growth factor which then accumulated in the hydrogel IOL,resulting in proliferation of lens epithelial cells as was observed in this patient.
