After an over-refraction on soft lenses of 8.8-4.00 14.0 results in -0.75D sphere, which parameters would you order for the patient?

When conducting an over-refraction on a patient wearing soft contact lenses, the result indicates that the current lens power does not fully compensate for the patient's vision needs. In this case, the over-refraction resulted in a -0.75D sphere, which suggests that the patient is slightly under-corrected by the original lens prescription of 8.8-4.00 14.0.

To adjust for the under-correction indicated by the over-refraction, you would need to order lenses with a slightly higher power. The decision to choose a lens with a power of -4.75D (denoted as 8.8-4.75 14.0) is grounded in the need to compensate for the -0.75D that was measured during the over-refraction. This adjustment should improve the visual acuity for the patient, as a more powerful lens should bring their vision into clearer focus.

Choosing a lower power lens (like -3.25D) would not adequately address the vision correction needed, while sticking with the original (-4.00D) would similarly fail to compensate for the -0.75D deficit. A power of -5.25D would be overcorrecting the prescription, potentially
