Abstract Details


To independently confirm measurement of the irradiation levels used in clinical corneal collagen cross-Linking devices

Setting: Eye Institute, Athens, Greece


Laboratory-graded UVA digital light radiometers (DigiProbe, sglux SolGel Technologies GmbH, Berlin, Germany) were employed to independently measure UVA (365 nm - centered) irradiation levels in four CXL devices in current clinical use: (KXL I and KXL II, Avedro, Waltham MA, Vega, CSO, Scandicci Firenze, Italy, and the UVX 2000, IROC Innocross AG, Zug, Switzerland) were measured. The per-manufactured suggested working distances and other environmental parameters were observed. Temporal variations during measurement, as well as comparison of averages between different-session measurements were recorded.


Average fluence measured were, for the KXL system, 29.5 ± 1.3 mW/cm2 (manufacturer-released, 30 mW/cm2), for the Vega system, 2.8 ± 0.3 mW/cm2 (manufacturer-released, 3 mW/cm2), and for the UVX system, 2.6± 0.7 mW/cm2


Independent, laboratory investigation of clinical CXL devices reveals that the KXL systems are closely matched to manufacturer-released fluence values with little intra-operating deviations FINANCIAL INTEREST: One of more of the authors... travel has been funded, fully or partially, by a company producing, developing or supplying the product or procedure presented
