ABSTRACT:
A phantom cornea for calibrating surgical lasers is formed by superimposition of thin-films of alternating colors. After ablation by a laser beam, the resulting spherical cavity appears as a pattern of nested circles whose concentricity and spacing reflect the alignment and intensity of the laser beam. These patterns can be visually or instrumentally analyzed to determine the proper setting of the laser. The calibration cornea can be planar, or arcuate to mimic the natural cornea. The calibration cornea may be mounted in a phantom eyeball including a removable iris of small diameter which constitutes a convenient target for the alignment of the laser beam.
