PURPOSE To compare clinical outcomes, functional vision, and spectacle freedom in patients 70 years or younger with bilateral ReSTOR (Alcon Laboratories) or ReZoom (Advanced Medical Optics) intraocular lenses (IOLs). SETTING Private practice, Los Altos, California, USA. METHODS Thirty patients had nonrandomized bilateral implantation of a ReZoom or ReSTOR multifocal IOL. Patients were 70 ye...

PURPOSE To assess clinical outcomes and subjective experience after bilateral implantation of a diffractive trifocal intraocular lens (IOL). SETTING Midland Eye Institute, Solihull, United Kingdom. DESIGN Cohort study. METHODS Patients had bilateral implantation of Finevision trifocal IOLs. Uncorrected distance visual acuity, corrected distance visual acuity (CDVA), and manifest refractio...

Background. The vision with diffractive toric multifocal intraocular lenses after cataract surgery in long eyes has not been studied previously. Objectives. To report visual performance after bilateral implantation of a diffractive toric multifocal intraocular lens in high myopes. Methods. Prospective, observational case series to include patients with axial length of ≥26 mm and corneal astigma...

INTRODUCTION The aim of the study was to compare the visual performance of LASIK eyes measured using high-contrast logMAR letter charts under bright (photopic) and dim (mesopic) conditions. MATERIALS AND METHODS A total of 46 subjects (35 +/- 8 years of age) undergoing LASIK procedures were recruited for the study. The best spectacle-corrected visual acuity (BSCVA) of each subject was measure...

This study investigates the time-course and post-receptoral pathway signaling of photoreceptor interactions when the rod (R) and three cone (L, M, S) photoreceptor classes contribute to mesopic vision. A four-primary photostimulator independently controls photoreceptor activity in human observers. The first experiment defines the temporal adaptation response of receptoral (L-, S-cone, rod) and ...

AIMS To compare the quality of vision of patients with customised aspheric intraocular lenses (IOL) versus patients implanted with zero-aberration IOL after a 1.8 mm micro-incision cataract surgery (MICS). METHODS Fourty-three eyes were divided into two groups: 17 eyes (reference group) received zero aberration Acri.Smart 46LC and 26 eyes received a customised-aspheric IOL: either aspherical ...
