Abstract

Purpose:

To report the technique and result of keratopigmentation using a femtosecond laser for the treatment of functional visual disabilities caused by peripheral iridectomies.

Design:

Case report.

Methods:

Two eyes of 2 patients underwent femtosecond laser-assisted keratopigmentation (FLAK) for moderate to severe visual dysfunction secondary to peripheral iridectomies. The main outcomes measures of the study were changes in visual-related symptoms, cosmesis, and intraoperative surgical complications.

Results:

Following FLAK, the visual-related symptoms (ghosting, glare, and monocular diplopia) improved in both cases with significant improvement to total elimination of symptoms. No patient lost any lines of visual acuity, and no significant complications were observed during the follow-up period. The cosmetic appearance was reported as very good.

Conclusions:

FLAK is minimally invasive and results in a significant decrease in the subjective glare and photophobia and even in resolution of monocular diplopia. The cosmetic outcome was also favorable. This technique allows surgeons to correct visual disabilities associated with iris defects with a high success rate while avoiding more aggressive intraocular surgery.
