Patent number: 11833031Abstract: A laser scanning method for forming a Fresnel type gradient index lens in an intraocular lens IOL. The radial profile of the desired optical pathlength (OPL) difference to be achieved in the IOL has multiple zones, each zone ramping from unchanged OPL to one wave, and stepping down to zero. To form a zone of a predefined OPL difference profile, the laser beam is scanned in multiple passes; in each pass, the laser beam is scanned in concentric circles of varying radii covering all or a part of the zone, with laser energy ramping up (along the radius) to a maximum allowed energy and staying at that energy. The ramp up region, which is dependent on the predefined OPL difference profile and the maximum allowed energy, is short, and most part of the pass is scanned at the maximum allowed energy.Type: GrantFiled: April 9, 2020Date of Patent: December 5, 2023Assignee: AMO Development, LLCInventors: Georg Schuele, David A. Dewey, Jenny Wang, Richard Hofer, Alexander Vankov
