Management of sequential intraocular lens dislocations in a single eye following prior complicated cataract surgery: A case report.

Dislocation of the intraocular lens after cataract surgery is uncommon but can cause a serious complication. We present a rare case of a patient with a dislocated posterior chamber intraocular lens and subluxated anterior chamber intraocular lens in the same eye, including its management, complications, and visual outcomes. A 65-year-old man with a history of cataract surgeries was found to have two displaced intraocular lenses in one eye, one subluxated within the anterior chamber and another dislocated into the vitreous cavity. Surgical procedures were performed to remove both displaced intraocular lenses, followed by the management of postoperative complications. After removal of intraocular lens implants via pars plana vitrectomy and insertion of scleral-fixated intraocular lens, the patient developed postoperative cystoid macular edema and epiretinal membrane. Subtenon triamcinolone acetonide injection partially resolved the cystoid macular edema, and the visual outcome was satisfactory. Understanding this case may aid in surgical planning and facilitate effective postoperative management of complications, ultimately leading to an optimal visual outcome.
