Ozer MD, et al. - In patients with progressive keratoconus in the pubertal period, researchers reported long-term outcomes of accelerated corneal collagen cross-linking treatment. For this investigation, they retrospectively reviewed patients with progressive keratoconus aged 14 and younger. The research included 35 eyes of 23 patients [mean age was 13 ± 0.5 (11–14) years] who were followed for at least 4 years postoperatively. Data reported that the mean pupillary center to cone apex distance was 1.6 ± 0.5 mm. Despite adequate therapy, progression was determined in 20% of the eyes after an average follow-up of 56 months. Progress was discovered to be associated with K1, K2, central corneal thickness, the thickness of thinnest point of the cornea, and age during the last visit.
