Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In the present study the investigators compare the clinical outcome corneal cross linking with either the stand-ard Dresden (sCXL) or the accelerated custom-fast (aCFXL) ultraviolet A irradiation protocol using riboflavin-D-α-Tocopheryl polyethyleneglycol1000 succinate for progressive keratoconus.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

sCXL

Standard protocol of Dresden Riboflavin-VEPTGS solution applied every 2 mins during UV UVA fluence of 3mW/cm2 UVA Irradiation time 30 minutes

Group Type ACTIVE_COMPARATOR

Standard CXL

Intervention Type OTHER

The standard CXL procedure has been carried on following the Dresden protocol

aCFXL

Accelerated custom fast CXL protocol. The protocol has been developed on a published mathematical model that takes into consideration objective variables such as the equation governing the UVA-induced riboflavin con-sumption rate and the corneal thickness at its thinnest point.

Riboflavin-VEPTGS solution: Epithelial lavage before UV UVA fluence of 1.8 ±0.9 mW/cm2 UVA Irradiation time 10 ± 1.5 minutes

Group Type EXPERIMENTAL

accelerated custom-fast CXL

Intervention Type OTHER

The accelerated custom fast CXL (aCFXL) has been developed on a published mathematical model that takes into consideration objective variables such as the equation governing the UVA-induced riboflavin consumption rate and the corneal thickness at its thinnest point. By knowing both values, the mathematical model allows to objectively calculate both the exact UVA irradiation value (intensity), expressed in mW/cm2, and the irradiation time
