In-the-bag nasal intraocular lens optic truncation for treatment of negative dysphotopsia.

We describe in-the-bag nasal intraocular lens (IOL) optic truncation, a new technique for the treatment of negative dysphotopsia. After a plane is created between the nasal capsular bag and the IOL, micrograspers and intraocular scissors are used to amputate the nasal optic edge. The amputation is to reduce the optical impact of the IOL edge and nasal anterior capsule on the occurrence of negative dysphotopsia. The technique addresses many of the proposed mechanisms contributing to the development of negative dysphotopsia and can theoretically be used in all patients with chronic symptomatology. In the case we describe, the dysphotopsia resolved immediately after in-the-bag nasal IOL optic truncation.
