Patent number: 11654052Abstract: An ophthalmic surgical laser system and method for forming a lenticule in a subject's eye using “fast-scan-slow-sweep” scanning scheme. A high frequency scanner forms a fast scan line, which is placed by the XY and Z scanners at a location tangential to a parallel of latitude of the surface of the lenticule. The XY and Z scanners then move the scan line in a slow sweep trajectory along a meridian of longitude of the surface of the lenticule in one sweep. Multiple sweeps are performed along different meridians to form the entire lenticule surface, and a prism is used to change the orientation of the scan line of the high frequency scanner between successive sweeps. In each sweep, the sweeping speed along the meridian is variable, being the slowest at the edge of the lenticule and the fastest near the apex.Type: GrantFiled: November 11, 2020Date of Patent: May 23, 2023Assignee: AMO Development, LLCInventors: Hong Fu, Alireza Malek Tabrizi, Nima Khatibzadeh
