Positive and negative dysphotopsias in patients with the posterior chamber intraocular lens implanted after cataract surgery

Abstract

Modern technologies of examining cataract patients and phacoemulsification with implantation of the posterior chamber intraocular lens (IOL) commonly allow achieving the desired anatomical outcome and a high functional outcome after surgery. The development of postoperative dysphotopsias in patients with a posterior chamber IOL, however, requires a separate consideration. Dysphotopsia can develop practically in any eye with the IOL after cataract surgery and in some cases can affect postoperative vision, which hinders the patient from resuming working life as usual. Clear systemic guidelines for preventing postoperative dysphotopsia are still to be developed.
