The objective refraction with the auto refractometer vs. the subjective refraction with traditional
method and phoropter
Ernesto Valdenegro

T
oday the use of the computerized refractometer has become popular in the ophthalmological and optometric consultation,
being the most used instrument in the daily clinic, forgetting the importance of the subjective refraction with probines
lenses, either of the phoropter or of the lens box, even static and dynamic retinoscopy. This study shows the strengths and
weaknesses of automatic objective refractive methods, compared with results obtained by traditional subjective refraction
methods. The instrumental hyperopia and the effect of the conoid of Sturm, in the correction of irregular astigmatisms, such
as those produced after cataract surgery, or a keratoplasty, even after refractive surgery; they have refractive adjustment values,
which are necessary to prescribe to achieve optimal visual acuity. We seek for our patient a visual acuity 20/20 or a visual acuity
20/happy, where the visual comfort is the best with the ideal refraction.
