A medical image processing system and method, and a computer readable medium for processing a medical image are provided, which can be used for detecting, classifying, and/or assisting in diagnosing cataract. A data acquisition module is used to acquire an ultra-wide field fundus image, a cropping module is used to crop the ultra-wide field fundus image into a cropped image, and a deep learning module is used to detect and determine a classification of a lens opacification type corresponding to the cropped image. Therefore, an automatic screening for cataract can be realized with an increased detection rate and a decreased false negative rate, and ophthalmologists can thus cut down diagnosis time with increased examination efficiency. Also, telemedicine can be achieved accordingly.

Systems and methods for performing laser cataract surgery, for using a biometric system to determine a material property of a structure of the eye, laser pulses in a laser shot pattern having different powers. A therapeutic laser, and laser delivery system having the capability to vary the power of the laser beam.

A slit lamp microscope of an aspect example includes a scanner and a data processor. The scanner is configured to scan an anterior segment of a subject's eye with slit light to collect a plurality of cross sectional images. The data processor is configured to generate opacity distribution information that represents a distribution of an opaque area in a crystalline lens, based on the plurality of cross sectional images collected by the scanner.
