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.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
