TLDR
The aspheric IOL provided good functional vision at far and near, with lower performance at intermediate distance; good photopic contrast sensitivity and lower mesopic performance; and a low incidence of visual disturbances.Abstract:
Purpose To evaluate distance, intermediate, and near vision after bifocal aspheric AcrySof ReSTOR SN6AD1 intraocular lens (IOL) implantation. Setting Fernandez-Vega Ophthalmological Institute, Oviedo, Spain. Methods Binocular distance best corrected visual acuity (BCVA) (4.0 m), best distance-corrected near (40.0 cm) and intermediate (70.0, 60.0, 50.0 cm) acuities, and contrast sensitivity under photopic (85.0 candelas [cd]/m 2 ) and mesopic (3.0 cd/m 2 ) conditions with and without glare were measured postoperatively. A patient-satisfaction and visual phenomena questionnaire was administered. Results Six months postoperatively, the mean acuities (logMAR) were binocular BCVA, −0.064 ± 0.049 (SD); best corrected near, −0.041 ± 0.061; best corrected intermediate, 0.147 ± 0.130 (70.0 cm), 0.036 ± 0.133 (60.0 cm), and −0.126 ± 0.077 (50.0 cm). The BCVA and best corrected near acuity were 20/25 or better in all patients. Through-focus binocular logMAR acuities had 2 peaks at the expected far focus and near focus (0.00 diopter [D] and −2.40 D, respectively), with somewhat reduced acuity (20/32) at intermediate distances. Photopic contrast sensitivity was within the standard normal range. Mesopic contrast sensitivity was lower than under photopic conditions, particularly at higher spatial frequencies. Patients reported good performance for distance, near, and intermediate visual tasks with no or minimal difficulty with specific tasks. No patient reported severe visual phenomena; halos and glare were rated as none to moderate. Conclusions The aspheric IOL provided good functional vision at far and near, with lower performance at intermediate distance; good photopic contrast sensitivity and lower mesopic performance; and a low incidence of visual disturbances.read more

TL;DR: The results of implantation of multifocal IOLs of diffractive, refractive, and hybrid diffractive-refractive design are described with regard to uncorrected near and distance visual acuity and spectacle independence.

Design and qualification of a diffractive trifocal optical profile for intraocular lenses
TL;DR: The combination of 2 diffractive profiles to achieve far, intermediate, and near correction is validated and the IOL theoretically allows improved intermediate vision without impairing near and far vision and favors distance vision in mesopic conditions without increasing halos or glare perception under dim light or large pupil conditions.

Cataract extraction with multifocal intraocular lens implantation: A multinational clinical trial evaluating clinical, functional, and quality-of-life outcomes
TL;DR: Cataract patients who received multifocal IOLs at time of surgery obtained better uncorrected and distance corrected near VA and reported better overall vision, less limitation in visual function, less spectacle dependency, and more glare or halo than those who received traditional monofocal I OLs.

A prospective comparative study of the AMO ARRAY zonal-progressive multifocal silicone intraocular lens and a monofocal intraocular lens.
TL;DR: Although the perception of halos and glare increased in the multifocal eyes, good visual function remained, and nearly all subjects were satisfied with the results of their surgery, a large study that included a subset of subjects with paired eye compared with those with monofocal lenses concluded that this zonal-progressive multifocal lens provided a high level of uncorrected and corrected distance vision.

TL;DR: In this paper, the authors evaluated distance and near visual performance under bright (photopic) and dim (mesopic) conditions in patients who had undergone uncomplicated cataract extraction with multifocal or monofocal intraocular lens (IOL) implantation.
