A 57-year-old male came with complaints of defective vision in the left eye for the past 6 months. He had no history of systemic illness. He had a history of uneventful phacoemulsification surgery in the left eye 5 years back, also had a history of idiopathic intermediate uveitis in both eyes for the past 7 years and on long-term treatment with steroids and mycophenolate mofetil. Vision in the left eye was 6/60 not improving. On examination, the left eye showed complete dislocation of bag-intraocular lens (IOL) (single-piece foldable IOL) complex into the anterior chamber [Figure 1]a. Concentric fibrosed band on the anterior capsule with anterior capsular fibrosis was seen. No active uveitis was found in both eyes and intraocular pressure was normal. Fundus examination showed epiretinal membrane. The other eye showed pseudophakia with anterior capsular fibrosis and no decentration [Figure 1]b. As far as our research, this is the first case to be reported showing a complete bag-IOL complex dislocation into the anterior chamber spontaneously. The patient underwent IOL explantation with SFIOL and vision improved to 6/9 postoperatively.

One of the serious complications after an uneventful phacoemulsification surgery is IOL-bag complex dislocation which is very rare. It can be either anterior or posterior dislocation which occurs spontaneously. Early dislocation is <3 months and late dislocation is more than 3 months. Common causes are pseudoexfoliation, high myopia, post vitrectomy, intermediate uveitis, and retinitis pigmentosa. Significant fibrotic changes of capsular bag and anterior capsular phimosis due to metaplasia of retained lens epithelial cells cause a constant centripetal force on the capsular bag. This causes progressive zonular weakness and complete late in the bag IOL-bag complex dislocation. Most commonly seen in acrylic IOLs believed to be due to bio-incompatibility of IOL material in some individuals. Adequate capsulorrhexis, complete cleaning of the cortex, and minimal zonular stress prevent such complications.
