摘要：
A system and method for determining and monitoring a laser ablation volume of a cornea (14) is disclosed. The method includes sampling a beam of laser shots from a pulsed treatment laser (11) as a reference portion (19). A fluence distribution of the beam reference portion is measured, and a laser beam characteristic is calculated (104) from the measured fluence distribution. A system for determining and monitoring a laser ablation volume of a cornea includes a beamsplitter (16) that is positioned to split a beam of laser shots from a pulsed treatment laser into a corneal portion (18) and a reference portion (19). Devices (21) are provided for measuring a fluence distribution of the beam reference portion and for calculating an ablation volume per laser shot from the measured fluence distribution.
