The laser cutting experiments were carried out using a pulsed Nd:YAG laser (Model JK-704, GSI Lumonics) operated in the LD-1 mode having a fixed average power of 135 W. In addition, it can be done on people who have retinal diseases. 6-mm diameter, 9-mm length, micro short pulse (MSP), 20 Hz, 50 mJ, 1 W). This laser, with a wavelength of 2940 nm, produces laser irradiation in the near infrared portion of the electromagnetic spectrum. Nd:YAG laser vitreolysis involves using laser energy to fragment the vitreous opacities via a non‐invasive approach.
