With proper anatomical conditions, this lens also shows good results in hyperopic patients. Combined with corneal refractive surgery as an additional procedure, this pIOL shows the most predictable optical result. The main complications of irisfixated anterior chamber pIOLs are chronic subclinical inflammation, corneal endothelial cell loss, cataract formation, secondary glaucoma, iris atrophy and dislocation. Comprehensive preoperative evaluation and long-term postoperative follow-up examinations are needed to monitor for and prevent serious complications. This article is a review of iris-claw pIOLs, and addresses the results and their complications.
