The TRS system provides a level of refractive detail not attainable with traditional manual phoropter use. The TRS can refract down to 1-degree axis and 0.12 diopter power steps (for sphere). For some patients, such detailed outcomes can make the difference between an acceptable and an exceptional refractive correction. We now have ophthalmic laboratories that can fabricate lenses to those levels of specificity. This raises the bar in terms of the quality of vision correction we can provide for our patients.
