Question

Proclear Toric Multifocal - What is the fitting procedure?

a) Evaluate corneal curvature and astigmatism
b) Measure pupil size and visual acuity
c) Assess tear film and lens movement
d) All of the above

Answer 1

The fitting procedure for Proclear Toric Multifocal contact lenses includes evaluating corneal curvature and astigmatism, pupil size and visual acuity, and tear film and lens movement, thus the answer is (d) All of the above.

Step-by-step explanation:

The fitting procedure for Proclear Toric Multifocal contact lenses includes evaluating corneal curvature and astigmatism, measuring pupil size and visual acuity, and assessing tear film and lens movement. Therefore, the correct answer to the fitting procedure is (d) All of the above.

Vision Correction and LASIK Procedure

For question 8a, after a LASIK procedure that reduces the eye's power by 9.00 D with a ±5.0% uncertainty, the range of diopters for spectacle lenses would be calculated by taking 5% of 9.00 D, which equals 0.45 D. Thus, the range is from -9.45 D to -8.55 D. Regarding question 8b, the person was nearsighted, or myopic, before the procedure. This is known because the procedure reduced the power of the eye by 9.00 D, which is consistent with correcting for nearsightedness by flattening the cornea to decrease its power.
