Abstract

Systems and methods are provided for modulating laser treatment on the eye. In use, an eye of a patient is scanned using a laser scanning system to produce a scan result. A mapping of the eye is created based on the scan result. Additionally, a modulated treatment of the eye is created based on the mapping. Further, a laser illumination light beam is delivered to a first location on the eye of the patient in accordance with the modulated treatment.

Claims20

Dependent claims

A laser system, comprising:

a laser which includes radiation which is focusable as a laser illumination light beam;
a non-transitory memory storing instructions;
and
one or more processors in communication with the non-transitory memory, wherein the one or more processors execute the instructions to:
scan an eye of a patient to produce a scan result, wherein the scan result comprises at least one of optical coherence tomography (OCT), thermal imaging, or ultrasound data specifically of iris dilator muscle tissue depth and density;
create a mapping of the eye based on the scan result, wherein the mapping includes at least one of a depth map, optical density map, or color map, and wherein the mapping includes a three-dimensional depth map of iris dilator muscle tissue location;
create a modulated treatment of the eye based on the mapping, wherein the modulated treatment is configured to cause a decrease in diameter of a pupil of the eye by targeting at least a subset of iris dilator muscle tissue;
deliver the laser illumination light beam to a first location on the eye of the patient in accordance with the modulated treatment;
and
determine an effectiveness of the modulated treatment at the first location in real-time during delivery of the last illumination light beam based on at least one of thermal imaging, optical coherence tomography (OCT), or ultrasound;
wherein determining the effectiveness comprises measuring at least one of thermal uptake, depth and density, or change in optical density specifically of the iris dilator muscle tissue;
wherein determining the effectiveness comprises comparing measurements at the first location against the three-dimensional depth map to verify sufficient laser penetration to the iris dilator muscle tissue;
wherein the modulated treatment is automatically updated based on the determined effectiveness at the first location, and wherein the updated modulated treatment is used to guide treatment parameters for one or more second locations on the eye;
and wherein the modulated treatment is updated by adjusting at least one of laser power, pulse duration, or focal depth based on whether the measured effectiveness indicates sufficient weakening of the iris dilator muscle's ability to dilate the pupil and based on the comparison of the measurements against the three-dimensional depth map.
