PURPOSE: Compare the wavefront and contrast sensitivity of bilateral pseudophakic patients with aspheric in one eye and spheric intraocular lenses in the other. METHODS: This prospective, comparative, randomized study, double masked, included 32 eyes of 16 patients. A complete ophthalmic evaluation was done before, and after surgery at days 1,3, 7 and 90, and included best corrected visual acuity, the contrast sensitivity, under photopic and mesopic conditions, and aberrometry. Almost all exams were done monocularly with undilated pupils (aberrometry under […]

OBJECTIVE: To show visual and refraction results using multifocal diffractive apodized intraocular lens. METHODS: The study of 100 eyes of 50 patients with cataract, submitted to phacoemulsification with bilateral implant of multifocal diffractive apodized intraocular lens (IOL). Binocular visual acuity was evaluated with and without correction for near and distance, and refraction previsibility and frequency of wearing glasses. RESULTS: Visual acuity without correction for distance was e” 20/30 in 97.56% of eyes operated on and e” J2 in 100%, of […]
