摘要： An optically and physically representative model eye (50, Figure 3) is employed in a model eye system to evaluate corrective lenses and corneal modification. The illustrative model eye (50) has a mounting ring (52) that holds a simulated cornea (54), iris (56) and lens (58). A photoactive device (64) such as a photodetector array (65) is mounted on a movable base (66) for movement within a retinal area (70). A liquid-tight posterior enclosure (72) is formed by a flexible tubular bladder (73) so that the device is immersed in a liquid that simulates optical properties of the natural vitreous humor. The base (66) and photodetector array (65) are moved by rotary and linear actuators (not shown in Figure 3) to position the device angularly within the retinal area (70) and to reciprocate it to achieve through-focus at any position in the retinal area (70). A conventional eye-test chart (91) in a field of view (69) can be imaged via a mirror (92) and a test contact lens can be placed on the model cornea (54) with a simulated tear solution under a protective cover (84). A camera (87) can be used to check the alignment and orientation of the test lens.
