Dropped Nucleus Postintravitreal Injection with Intact Anterior Capsule: a Case Report

Case Presentation: A 58-year-old female with uncontrolled type 2 diabetes mellitus presented with decreased vision bilaterally. At presentation, the anterior segment of both eyes showed nuclear sclerosis +2. Fundus examination of the left eye was not visible due to diffuse vitreous hemorrhage, for which an intravitreal ranibizumab injection was given. She presented for follow-up 3 weeks later; an aphakic left eye was discovered during the examination. A dropped nucleus was diagnosed, and the patient underwent an uneventful pars plana vitrectomy with removal of the dropped nucleus and implantation of a sulcus three-piece intraocular lens. Postoperatively, the vision had improved from hand motion to 6/18. Clinical discussion: this case presentation reports an unusual complication of a dropped lens nucleus after IVI. It highlights the possibility of inadvertent lens trauma in such a procedure and the importance of proper adherence to standards to avoid such a complication.

Conclusion: This rare complication highlights the importance of carefully following IVI guidelines in the hands of experienced ophthalmologists and the need for meticulous supervision for ophthalmology residents because it is not a risk-free procedure.
