摘要
Control apparatus (1) for controlling the dosing of a chromophoric agent (100) in a corneal tissue (101), comprising: a first source (2) for irradiating the corneal tissue (101) with at least a first electromagnetic radiation (21); first measurement means (3) for measuring a first spectroscopic parameter (31), such as the fluorescence intensity or the diffused intensity; a processing unit (4) configured to calculate a factor (C) representative of the concentration of the chromophoric agent (100) inside the corneal tissue (101) in response to at least two measurements of the first spectroscopic parameter (31), of which one measurement is indicative of the energy perturbation caused by the first electromagnetic radiation (21) in the corneal tissue (101) without the chromophoric agent (100) and the further measurement is indicative of the energy perturbation caused by the first electromagnetic radiation (21) in the corneal tissue (101) containing the chromophoric agent (100).
