New keratoconus classification guides customization of intracorneal ring segment implantation

OVIEDO, Spain — A new keratoconus classification oriented to the implantation of intracorneal ring segments was presented at the second European Meeting of Young Ophthalmologists. “Our classification is aimed at using Ferrara rings and originates from Ferrara’s morphological classification. It is based on ectasia location and uses asphericity, topographic astigmatic patterns and the relationship between topographic, comatic and refractive axis as parameters,” Luis Fernández-Vega, MD, said.
