Title: ACCOMMODATIVE IOL’s OBJECTIVE EVALUATION USING A NOVEL DOUBLE–PASS BASED INSTRUMENT
Abstract: Methods:We recorded retinal images during accommodation of 30 pseudophakic eyes of 18 patients using a double–pass system (OQAS; Optical Quality Analysis System, Visiometrics SL). Measurements were performed with physiological pupil (no cyclopegic) between 4 to 6 weeks after an uncomplicated surgery. Mean spherical equivalent refraction was –0.75+0.50 diopters (range –1.25 to +0.50 diopters). Ten eyes were implanted with an accommodative IOL (AT–45,C&C Vision), ten more with a ThinOptx IOL (Abingdon,VA) and ten more as control, five with an acrylic IOL from Corneal (Paris,France) and 5 from Alcon (Fort Worth,TX). Amplitude of accommodation in the OQAS instrument is defined as the range with image quality value 50% of the maximum (for best focus) or higher when analyzing the retinal image during the accommodation test target. This test is performed in both eyes separately.
