Dysphotopsias are visual phenomena that can occur following uncomplicated surgery to place an intraocular lens (IOL). There are two major categories of characteristic symptoms: negative dysphotopsias, such as dark shadows noted temporally, and positive dysphotopsias, such as areas of light, starbursts, streaks, or central flashes of light. An estimated 19 to 49% of patients will experience dysphotopsias after cataract surgery.1,2,3 The majority of these patients will report spontaneous resolution of their symptoms.4,5 For a minority, however, further intervention, including surgical intervention, will be required for complete resolution of symptoms. Dysphotopsias can be a particularly frustrating problem for surgeons because they generally occur after uncomplicated surgery. Slit-lamp exam after the surgery will likely reveal a well-centered posterior chamber IOL in the capsular bag with a normal capsulorhexis edge, normal pupil size, and normal corneal shape. Dysphotopsias are the most significant negative factor impacting patient satisfaction with such uncomplicated surgeries.
