Purpose
To assess safety, efficacy and complications of therapeutic femtosecond laser assisted (FA) and manual automated (MA) keratopigmentation (KTP) using micronized mineral pigments.
Setting
Eye Research Center, The Five Senses Health Institute, Moheb Kowsar Hospital, Iran University of Medical Sciences, Tehran, Iran
Methods
KTP was performed in 85 eyes of 85 patients with moderate to severe visual disabilities (range: 20/80 to NLP) related to various etiologies causing corneal scar or iris abnormalities. 36 eyes were treated by FA-KTP, 46 eyes by MA-KTP and 3 eyes using combined MA and FA-KTP. The cosmetic outcome, patient satisfaction, stability of pigmentation, and presence of any related complications are reported. The mean follow-up period was 10.8 months (range: 1-53 months).
Results
68 of 85 patients reported cosmetic satisfaction within the follow-up period. 74% of MA-KTP group, 86% of FA-KTP group and 100% of combined group were satisfied. 12 eyes of MA-KTP and 5 eyes of FA-KTP group required additional KTP procedure due to color fading and cosmetic unsatisfaction. Post-operative symptoms were photophobia (28%), tearing (24%) and pain (8%).Complications were dry eye (6%), delayed epithelial healing (2%) and microbial keratitis (1%).
Conclusions
FA-KTP and MA-KTP using MMP are safe and efficient surgical techniques for management of cosmetic and visual disturbances caused by iris abnormalities and corneal scars.
