Rotationally asymmetric multifocal IOL implantation in acquired nystagmus with spectacle and contact lens intolerance

摘要

PURPOSE: To describe a case of refractive lens exchange with multifocal intraocular lens implantation in a 52-year-old woman with emmetropic presbyopia who had near glasses and contact lens intolerance after acquired nystagmus. METHODS: Preoperative corrected distance visual acuity was 20/25 in the right eye, 20/20 in the left eye, and 20/20 binocularly. Corrected near visual acuity was 20/30 in the right eye and 20/20 in the left eye, reaching 20/20 binocularly but showing unsatisfactory binocular vision with asthenopia and intolerance to prolonged reading. The surgical plan entailed bilateral implantation of multifocal intraocular lens. RESULTS: Three months postoperatively, uncorrected distance visual acuity was 20/20 in the right eye and 20/20 in the left eye, reaching 20/20 binocularly. Monocular and binocular uncorrected near visual acuity of 20/20 was achieved without symptoms of asthenopia in prolonged reading. There were no changes in nystagmus characteristics after surgery. CONCLUSIONS: Multifocal intraocular lens implantation to manage a case of clinically significant acquired nystagmus may be a safe alternative, especially if others options have failed.
