Schematic rat eye model with main parameters needed for refractive state estimation (see Table 1). A1 (corneal surface) through A7 (vitreoretinal border) are distances along the horizontal dashed line; 130 μm was added to A7 to approximately account for the postreceptor retina contribution. If A1 is set to 0 mm from corneal surface and numbers increase from top to bottom, then rC1, rC2, rL1, and rLC1 are positive, while rLC2 and rL2 are negative.
