DEVICES FOR TESTING TORSIONAL ALIGNMENT BETWEEN A DIAGNOSTIC DEVICE AND A LASER REFRACTIVE SYSTEM

摘要

Test devices and kits for testing an alignment measurement between a diagnostic device and a laser refractive system are disclosed. One such test device includes a body including a proximal portion and a distal portion. The proximal portion defines a corneal surface and an iris, and the distal portion defines a retinal surface. The iris surface comprises one or more texture patches for facilitating measurement of a cyclotorsional rotation of the test device. The retinal surface defines a diffuse surface configured to absorb light. Another such device includes a body, and means for providing optical torsion alignment markers. The device further includes means for providing a retinal surface and means for providing a corneal surface. The device further includes a measure configured to evaluate the position of the torsion alignment markers to facilitate measurement of a cyclotorsional rotation of the device.
