Reason
We have confirmed that our ophthalmic surgical treatment planning software, CRS-Master Treatment Planning (Approval No.: 22700BZX00354000), was shipped with an unapproved optional feature called “ZEISS PRESBYOND” (a simulation function for cases where irradiation is performed with different target refractive powers for the left and right eyes; hereinafter referred to as “the optional feature”).
