FLIO images (SSC) of subjects who were 74 years old (top row), 77 years old (middle row), and 80 years old (bottom row). (Left to right) Mean lifetime τm postoperative, τm preoperative model 0, τm preoperative model 1, and τm preoperative model 2. Color-coding is scaled identically for all models per subject as indicated (50–450 ps, 50–500 ps, and 50–400 ps, respectively). Images are scaled in pixels; the size of 1 pixel is 35 × 35 µm2 in an emmetropic eye.
