PURPOSE: To report wavy horizontal artifacts on optical coherence tomography (OCT) monitor images. SETTING: Tokyo Dental College Suidobashi Hospital, Department of Ophthalmology, Tokyo, Japan. METHODS: The line-scanning ophthalmoscopy images from an OCT device of eyes that had uneventful cataract extraction with implantation of a diffractive multifocal intraocular lens (IOL) were evaluated. The images were compared with those of eyes that had cataract surgery with implantation of a monofocal IOL. RESULTS: The study evaluated 38 eyes of 19 patients with a diffractive multifocal IOL and 29 eyes of 18 patients with a monofocal IOL. Wavy horizontal artifacts were seen in all eyes with a multifocal IOL but not in any image of eyes with a monofocal IOL (P<.0001, Fisher exact probability test). The OCT images, fundoscopic photographs, and scanning-laser ophthalmoscopy images were unaffected by the multifocal IOLs. CONCLUSION: The aberrations in the images from line-scanning ophthalmoscopy may have been caused by the optical design of the diffractive multifocal IOLs.
