Alio JL, et al. – This study is performed to report the complications found in a consecutive large series of cases treated with keratopigmentation (KTP). As per their knowledge, this is the first time a study systematically and comprehensively approaches and reports KTP complications. KTP with third GP provides better results and fewer complications than previous ones. It is a modern, minimally invasive technique that helps solve several functional ocular problems and improves the cosmetic appearance of the patients. Dermatological pigments ought not to be utilized as they lead to complications; instead pigments particularly tested for the eye in terms of toxicity and teratogenicity ought to be utilized.

Methods

• In this study, they performed KTP in 234 eyes of 204 patients for therapeutic and cosmetic reasons.
• 50 eyes of 29 patients suffered complications from these participated patients.
• In this study, they used different KTP techniques and three generations of pigments (GP).
• The follow–up period ranged from 4 months to 12 years.
• Light sensitivity (LS), visual field (VF) limitations and MRI alterations were considered functional complications.
• Organic complications were depicted as the change in colour, colour fading and neovascularisation.

Results

• In this study, they found the percentage of complications was 12.82%.
• Most patients complained of LS (49%), then colour fading and change in colour (19%).
• Neovascularisation, VF limitations and MRI complications constituted 7%, 4% and 2%, respectively.
• Organic complications were found with the previous GP but resolved with the latest third GP with CE mark certification (Conformité Européene).
• Although LS remained with the corneal–specific pigments, it gradually disappeared in most of the patients (81.81%) 6 months postoperatively.
