Wavy horizontal artifacts on optical coherence tomography line-scanning images caused by diffractive multifocal intraocular lenses.
OBJECTIVE
To report wavy horizontal artifacts on optical coherence tomography (OCT) monitor images.


METHODS
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.


CONCLUSIONS
The aberrations in the images from line-scanning ophthalmoscopy may have been caused by the optical design of the diffractive multifocal IOLs.
