Cataract surgery with intraocular lens insertion has become one of the most common and successful surgical procedures in modern medicine. Unfortunately, there are rare circumstances that require removal and exchange of the IOL implant.
On rare occasion, the IOL implant may need to be removed. This can be a result of wrong lens power, wrong position (dislocation), improper contact with tissue, or some other cause of inflammation or injury to the eye. Fortunately, dislocation of the IOL is uncommon but when this occurs it can involve the vitreous and posterior segment, including the retina placing the eye at risk for further complication. Today’s video demonstrates a meticulous removal and exchange procedure that minimizes vitreous traction, uses a new IOL for sulcus fixation. To make sure it has adequate support and does not dislocate again, additional security is achieved with a 10-0 Polypropylene suture using a McCannel suture technique. Alan N. Carlson, M.D., Professor of Ophthalmology and Chief of the Corneal and External Disease Service at the Duke Eye Center in Durham, NC feels that meticulous attention to these unusual cases can often return the patient to normal or near normal recovery status.
