Title:
SYSTEM AND METHOD FOR REDUCING POST-SURGICAL RAINBOW EFFECT
Document Type and Number:
Japanese Patent JP2021006267
Kind Code:
A
Abstract:
To provide a pulsed laser system that can obtain an interspersed pattern of photodisruptions with high irregularity.SOLUTION: A pulsed laser system comprises: a laser source that generates a laser beam; a scanner that controls the location of a beam focal point of the laser beam and also the location of a photodisruption formed at the beam focal point in a cornea of an eye; a computer that generates instructions to the laser source and scanner to control the formation of a regular photodisruption pattern in the cornea; and a noise source that disturbs the location of each photodisruption to cause an irregular photodisruption pattern to form in the cornea, such that diffraction of light by the cornea after the formation of the photodisruption pattern is decreased or avoided.SELECTED DRAWING: Figure 2A
