BLOG: Primary reverse optic capture for negative dysphotopsia
The phenomenon of negative dysphotopsia (ND) after a successful cataract surgery can be very distressing both to the surgeon and the patient, who usually complains of visualization of a dark shadow in the temporal field of vision. As reported in the literature, pharmacologic dilation of the pupil relieves the symptoms, whereas constriction of the pupil with miotics accentuates the crisis.
