Orthokeratology.
A. Pre-teens and young adults
B. Presbyopes and teenagers
C. Pre-teens and people approaching 50 years of age
D. Teenagers and people coming near 30 years of age
25. The answer is D.
A the front surface toric lens will show clear mires in all meridians which indicates a spherical
posterior floor. Warped, bitoric and returned floor toric lenses will all show doubtful mires within
the radiuscope indicating that the posterior floor is not round. In the lensometer, bitoric, returned
toric and front surface toric lenses will all show sphero-cylindrical readings. Only the warped
lens will show a round lensometer analyzing. - ANS-25. When verifying the posterior curves of a
rigid fuel permeable now not all the mires are clear
in all meridians. This can arise in all but a:
A. Warped lens
B. Bitoric lens
C. Back surface toric lens
D. Front floor toric lens
50. The solution is C.
When considering sagittal intensity, if the base curves of the lenses are the same, the smaller
the diameter, the shorter the depth. This shows that the 14.Zero diameters are looser than the
14.5 diameters. If the lens diameters are equal, the flatter the base curve, the looser the lens.
Therefore, the eight.8 would be flatter than the eight.Four and confirms that the eight.Eight base
curve with the 14.Zero diameter might maximum loosely suit of the alternatives given. - ANS-50.
