SummaryThree cases are reported in which the ametropic corrections were very moderate in amount, the spherical component ranging from zero to plus one diopter, and the cylindrical component from one‐eighth to one‐half diopter (see Table 1). All three Patients had histories of years of ocular discomfort unrelieved by any ametropic correction, Their iseikonic lenses gave them complete relief from their ocular discomfort. It will be noted that the aniseikonic correction in all three cases was meridional in character and ranged as follows: Case Report 1, M.C., 1¾% magnification axis 35. Case Report 2, T.A., the first iseikonic correction in 1946, was 4% magnification axis 90. The second iseikonic correction in 1951, was 1⅝% magnification axis 90. Case Report 3, L.M., the first iseikonic correction in 1940, was O.S. ½% magnification axis 90. The second and third iseikonic corrections in 1951 and 1953, were both O.D. 1% magnification axis 180.
