Fracture of a three-piece polyimide-elastimide intraocular lens at the optic-haptic junction following blunt trauma is a possible complication after cataract surgery. We report a case of an isolated posterior chamber intraocular lens fracture caused by direct ocular blunt trauma.
A 51-year-old patient underwent blunt orbital trauma caused by a raw chicken egg that was thrown at him, as he was walking. The posterior chamber intraocular lens was found in the anterior chamber, with a broken optic-haptic junction. The intraocular lens was exchanged, followed by iris fixation and pupilloplasty, with satisfactory postoperative anatomical and optical outcomes.
The three-piece polyimide-elastimide intraocular lens was fractured at the optic-haptic junction. Although the fractured intraocular lens surface had a regular appearance, it has been previously reported that the polyimide haptic's durability is probably inferior to that of polymethylmethacrylate. Therefore, it is highly susceptible to shear stress induced by a blunt trauma.
To our knowledge, this is an uncommon report of an implanted posterior chamber polyimide-elastimide intraocular lens fracture following blunt orbital trauma. Intraocular lens exchange and fixation had successful optical and anatomical results.
