研究组 & 干预措施
Assessment of intermediate vision, defocus curve
Standardized logarithm of the minimum angle of resolution (logMAR) charts were used for visual acuity measurement at 4 m, 80 cm, and 40 cm.
he binocular defocus curve: The binocular defocus curve was done to evaluate the functional range of vision. The curve was obtained while the patient wearing his distance correction to provide the best distance visual acuity in both eyes. The test was performed under photopic conditions (85 candelas/m2) using ETDRS charts at a distance of 4m with the introduction of defocusing lenses from +1.00 D to -4.00 D in 0.50 D steps.
干预措施: phacoemulsification (Procedure)
