摘要:

To summarise: The Turville method of subjective refraction was applied to 215 consecutive patients. The prescription determined by this method was given each patient regardless of the results of other tests and even against the writer's judgment in some cases. In slightly less than 10 per cent, of these subjects the prescription departed significantly from that which would have been given ordinarily. The prescription was changed in three out of these 21 cases at a subsequent date, two because of binocular difficulties arising from the incorporation of vertical prism and the third because some latent hypermetropia became manifest. A significant departure was assumed to be more than a 0.50 D. difference in the sphere, more than a 0.25 D. difference in the cylinder, 10d̀ or more difference in the axis of the cylinder, and/or the incorporation of prism power in the prescription.After using the Turville method for over one year, the writer's enthusiasm for it, as an addition to routine refraction, is greater rather than less. Of course, it is not a sure‐fire, fool‐proof method of satisfying every patient. It is an important addition to routine refraction, perhaps as important as the flip cross cylinder. The writer no longer applies the results blindly as was done during the testing period, but be now modifies the prescription as indicated by the other tests and sometimes by intuition only based on previous experi
