Retraction Note to: Combination of violet light irradiation and collagenase treatments in a rabbit model

To investigate the use of collagenase type II for generating a rabbit model of keratoconus and to evaluate the impact of violet light (VL) irradiation on the disease model. Six Japanese White rabbits were used. After epithelial debridement, the collagenase group was treated with a collagenase type II solution for 30 min; the control group was treated with a solution without collagenase. Three rabbits also underwent VL irradiation (375 nm,...
