Abstract: A computer implemented system and method for determining and analysing ocular refractive error of an eye. The method determines a set of sample biometric factors for a reference sample of eyes from a set of reference sample physical characteristics. Physical characteristics of a patient’s eye are measured such that the type of measured patient physical characteristics include some or all of the reference sample characteristic types. Patient biometric factors are then calculated based on the measured and inherent patient physical characteristics and compared with the sample biometric factors to determine the effect of one or more parameters on the ocular refractive error of an eye. The method may calculate the difference between the refractive contribution of the axial length, cornea and internal optics in the patient’s eye and the separate contribution from those factors in the sample physical characteristics.

Abstract: There is disclosed a pacemaker programmer for operation by a patient. The programmer can be pre-set by the physician to allow the patient to set his pacemaker in any one of a limited number of states, the states controllable by the patient being a sub-set of the set controllable by the physician with use of his conventional-type programmer. In the illustrative embodiment of the invention, while the physician programmer can control eight different rates, the patient programmer can set only three of these ("exercise", "awake" and "sleep" values), the particular values being preselected by the physician.
