Visual Discomfort Induced by Photosensitivity in Cataract Patients Following Intraocular Lens Implant Surgery

In cataractogenesis, vision deteriorates as the crystalline lens becomes hazier. This leads to opacity and eventually to light obstruction. Intraocular lens (IOL) implantation has become popular in recent years for the treatment of severe cataracts. Visual acuity and color perception are recovered in most patients following surgery. However, it was hypothesized that the recovery process may entail a hypersensitivity to visual stimuli, resulting in adverse symptoms similar to those in migraine patients. In this study, we conducted structured interviews with nine cataract patients regarding visual discomfort following lens implant surgery. Although most of the patients reported improved vision and quality of life, four described increased hypersensitivity to visual stimuli. Thus photosensitivity and visual discomfort may accompany the improvement in visual function after IOL implant surgery.
