Given an over refraction of -1.00-0.50X174 on a soft lens of 8.4-2.00 14.2, which parameters would you order for the patient?

When considering the over-refraction given as -1.00-0.50X174, the prescription indicates that the patient has a need for a more myopic correction and a slight cylindrical correction at a specific axis. The original lens parameters, 8.4-2.00 14.2, suggest a specific base curvature, power, and diameter.

The decision to select the parameters as 8.4-3.25 14.2 comes from the need to adjust the spherical power downward by the amount indicated by the over-refraction, which is -1.00. Therefore, changing the prescription from -2.00 to -3.25 accommodates this new spherical correction.

Moreover, maintaining the same base curve of 8.4 provides comfort, and keeping the diameter at 14.2 ensures that the lens fits appropriately for the patient's eye. This choice effectively addresses the visual needs while preserving comfort and fit.

Adjustments to the base curve and diameter were not necessary in this case, hence that explains why selecting 8.4-3.25 14.2 was the optimal choice for the patient, aligning with the indicated over-refraction requirements.
