Wavy horizontal artifacts on optical coherence tomography line-scanning images caused by diffractive multifocal intraocular lenses

From the Department of Ophthalmology (Inoue, Bissen-Miyajima, Yoshino, Suzuki), Tokyo Dental College Suidobashi Hospital, and Kyorin Eye Center (Inoue), Kyorin University School of Medicine, Tokyo, Japan

Received 19 December 2008; received in revised form 9 February 2009; accepted 10 February 2009.

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.
