Measuring visual acuity with a potential acuity meter is particularly useful for patients with cataracts. This specialized device helps assess how well a person can see through their cloudy lens, which is a characteristic feature of cataracts. The potential acuity meter projects a visual acuity chart onto the retina, bypassing the opacified lens and allowing for an estimate of the best-corrected visual acuity that the patient might achieve after cataract surgery. This measurement is critical in determining the degree of visual impairment caused by cataracts and in making informed decisions about surgical intervention.

While diabetes, glaucoma, and macular degeneration are important ocular conditions that affect vision, potential acuity meters are not specifically designed for assessing the impact of those conditions in the same way they assess cataracts. In cases of diabetic retinopathy, glaucoma, or macular degeneration, other testing methods (such as fundus photography or visual field testing) are more commonly utilized to evaluate the effects on vision.
