R. O. D. -|-2 sph. O — 4.50 cyl. axis 15 degrees.
O. S. +2 sph. O — ^4.50 cyl. axis 165 " SiG. — For constant use.
April 1 2th : Glasses neutralize ; are centered and adjusted.
April 26th : Near point 10 cm., which is consistent with age of patient.
Considerations. — The ophthalmoscope, retinoscope, cobalt-blue glass, indirect method, and ste...nopeic slit were direct guides to the character of the refractive error.
Emphasis is placed upon these different methods, as so many beginners in ophthalmology have a fear or dread of the re- sult in refracting cases of mixed astigmatism.
The stenopeic s/it shows a difference of 4.50 in the two principal meridians ; bearing this fact in mind, if a — ^4.50 cylinder at axis i $ be placed before the right eye, then all meridians would be made equally hyperopic 2 D. Com- bining + 2 sph. with the — 4, 50 cylinder at axis 1 5 in the right eye or at axis 165 in the left, the refraction would be corrected.
