The application provides a laser ablation assembly, comprising an ablation optical fiber and a cooling sleeve; the ablation optical fiber comprises a light-guiding optical fiber and an ablation tip; the cooling sleeve comprises a base, an inner tube and an outer tube, two communication structures are arranged in the base; a first support structure is arranged between the outer tube and the inner tube, a second support structure is arranged on the inner side of the inner tube, the distal end of the outer tube is a blind end, a space between the outer tube and the inner tube forms a first channel, a space between the inner tube and the optical fiber forms a second channel, the first channel and the second channel are in fluid communication at the distal end; the first channel is in fluid communication with one of the communication structures at the proximal end, and the second channel is in fluid communication with the other communication structure at the proximal end.

It provides moisture level adjustment for ophthalmic laser ablation surgery. [Solution] In a particular embodiment, the ophthalmic laser ablation system includes a laser device, a fluid removal device, and a computer. The laser device directs laser radiation towards the eye as multiple shots to cut the eye tissue according to a treatment pattern. The fluid removal device removes fluid from the surface of the eye tissue. The computer identifies a moisture retention procedure, instructs the fluid removal device to remove fluid from the surface of the tissue at a certain location in the eye according to the moisture retention procedure, and instructs the laser device to cut the tissue at that location in the eye according to the treatment pattern.
