PURPOSE To assess and compare the effects of contact lens-based artificial pupil design and contralateral balanced multifocal contact lens combination (CBMCLC) on visual performance. METHODS This randomized crossover study conducted at the University of Valencia, Spain included 38 presbyopic patients using an artificial pupil contact lens in the nondominant eye and a CBMCLC. After a month of ...

Purpose. To evaluate 2-year visual acuities and questionnaire after bilateral implantation of SN6AD1 multifocal intraocular lens (MIOL) or SN60WF IOL. Methods. Patients randomly scheduled for bilateral implantation of SN6AD1 MIOL and SN60WF IOL with 2-year follow-up were enrolled. Uncorrected/corrected distance and near visual acuity, uncorrected intermediate visual acuity at 63 cm under high a...

background: vision therapy/orthoptics(vt/o) is a package of treatments that enables patients to achieve the maximum level of visual performance.the aim was to determine the effect of three months vision therapy/orthoptics on best corrected visual acuity (bcva), fusion, stereopsis and ocular alignment in 3-7 year old children. materials and methods: in this randomized clinical trial study, 80 ch...

PURPOSE To report the postoperative binocular function of patients with Boston type I keratoprostheses implantation for unilateral visual impairment. METHODS Seventeen patients who underwent implantation of a Boston type I keratoprosthesis and had a best-corrected visual acuity better than 20/50 in the contralateral eye before surgery were evaluated. All subjects prospectively underwent senso...

BACKGROUND The purpose of this study was to record the visual outcomes of patients treated by six surgeons after implantation of a trifocal lens. METHODS The setting for this study comprised six ophthalmology units and eye clinics in Belgium and France, with a coordinating center in France, and data management and statistical analysis in France and Belgium. Ninety-four eyes from 47 patients w...

BACKGROUND The use of self-report questionnaires to substitute for visual acuity measurement has been limited. We examined the association between visual impairment and self reported visual function in a population sample of older people in the UK. METHODS Cross sectional study of people aged more than 75 years who initially participated in a trial of health screening. The association between...

PURPOSE To study the long-term visual and refractive outcomes and evaluate patient satisfaction after bilateral implantation of trifocal intraocular lenses (IOLs). SETTING Nethradhama Superspeciality Eye Hospital, Bangalore. DESIGN Prospective, nonrandomized study. METHODS Eligible patients undergoing bilateral phacoemulsification with trifocal IOL implantation were included. Follow-up ex...

PURPOSE The feasibility, in terms of safety and potential efficacy, of a new drug combination for binocular use as a noninvasive pharmacological solution for treating presbyopia was examined. METHODS Fourteen emmetropic presbyopic subjects (28 eyes) were given one drop of the preparation under study in each eye. For each patient, the uncorrected distance visual acuity, uncorrected near visual...
