A 76-year-old male presented with sudden defective vision in the left eye (LE) associated with a history of trauma sustained during a fall to the ground. The patient underwent phacoemulsification with foldable intraocular lens (IOL) implantation for the LE 1 year ago. Anterior segment evaluation in the LE revealed variable anterior chamber depth; capsular bag-posterior chamber intraocular lens (PCIOL) complex was found to be dislocated anteriorly into the anterior chamber [Figure 1]a, with the inferior haptic of PCIOL touching the endothelium. Dilated fundus examination and intraocular pressure (IOP) were normal in the LE. IOL explantation via the sclerocorneal tunnel was done in combination with pars plana vitrectomy (PPV), and scleral fixation of a three-piece IOL was performed in the LE [Figure 1]b. On postoperative day 1 (POD 1), BCVA in the LE was hand movements with the B-scan showing dispersed vitreous hemorrhage. IOP was recorded to be 42 mm Hg. Antiglaucoma medications were added to routine postoperative medications. Following a gradual improvement in subsequent follow-up visits, BCVA of 6/9 and IOP of 16 mm Hg were recorded after 5 months.

  Discussion Top

With a 0.2%–3.0% incidence rate, posterior chamber intraocular lens (PCIOL) dislocation is a rare and delayed complication of cataract surgery.[1] Posterior dislocations are much more common than anterior dislocations. Although anterior dislocation is rare, delayed intervention in such cases may lead to corneal decompensation, glaucoma, uveitis, and cystoid macular edema.[2] IOL repositioning with or without iris or scleral fixation, as well as IOL exchange, are all options for treating IOL dislocation. The technique used is based on the type of IOL implanted, surgeons' preference, and coexisting ocular pathology. The main postoperative complications are vitreous hemorrhage, post-inflammatory IOP spike, cystoid macular edema, recurrent IOL dislocation, and retinal detachment.[3] Early intervention and regular follow-up in such cases can give a better outcome.
