Trifocal lenses and cataracts

PURPOSE: To compare visual outcomes and performance between bilateral implantation of a diffractive trifocal intraocular lens (IOL) Acrysof(®)PanOptix(®) TFNT00 and blended implantation of two different near add power bifocal IOLs: Acrysof(®) Restor(®) SV25T0 in dominant eye and Acrysof(®) Restor(®) SN6AD1 in the nondominant eye. METHODS: This prospective, nonrandomized, consecutive and comparative study assessed 20 patients (40 eyes) who had bilateral cataract surgery performed using the IOLs described...

PURPOSE: To compare the visual outcomes and quality of vision of 2 new diffractive multifocal intraocular lenses (IOLs) with those of a monofocal IOL. SETTING: Fatebenefratelli e Oftalmico Hospital, Milan, Italy. DESIGN: Prospective case series. METHODS: Patients had bilateral cataract surgery with implantation of a trifocal IOL (Panoptix), an extended-range-of-vision IOL (Symfony), or a monofocal IOL (SN60WF). Postoperative examinations included assessing distance, intermediate, and near visual acuity; binocular defocus; intraocular and total aberrations; point-spread function (PSF); modulation transfer function (MTF); retinal straylight; and quality-of-vision (QoV) and spectacle-dependence questionnaires...

Presbyopia-treating intraocular lenses (IOLs) are now widely available and offer high predictability at all distances, better visual outcomes, and high patient satisfaction. In most patients, the same multifocal IOL is implanted bilaterally. In certain circumstances, such as during complex surgeries, it is important to be prepared with a backup plan to maintain surgical expectations. We report 3 patients who had femtosecond laser-assisted cataract surgeries in both eyes. The complicated eye had implantation of a bifocal IOL and the fellow eye of a trifocal IOL...

BACKGROUND: Today, patients often expect to achieve spectacle independance after cataract surgery. New trifocal intraocular lenses have been developed to try and fullfill this demand. The purpose of this study is to report the short-term visual outcomes of a new trifocal intraocular lens (AcrySof PanOptix™). METHODS: Consecutive adult patients undergoing cataract surgery with bilateral implantation of the study intraocular lens in a private practice clinic were considered for inclusion...

To assess the visual effects of trifocal intraocular lenses (IOLs) compared to bifocal IOLs in cataract surgery, a meta-analysis of prospective comparative clinical trials (including 4 randomized controlled trials and 4 cohorts) was conducted. The defocus curves showed a better distance-corrected intermediate visual acuity (VA) for the trifocal group (MD -0.07; 95% CI, -0.10 to -0.05; p < 0.00001), while the VA outcomes showed no significant difference in distance VA (MD -0.03; 95% CI, -0.06 to 0.01; p = 0...

PURPOSE: To compare visual outcomes after cataract surgery with bilateral implantation of 2 intraocular lenses (IOLs): extended range of vision and trifocal. METHODS: Each group of this prospective study comprised 40 eyes (20 patients). Phacoemulsification followed by bilateral implantation of a FineVision IOL (group 1) or a Symfony IOL (group 2) was performed. The following outcomes were assessed up to 1 year postoperatively: binocular uncorrected distance visual acuity (UDVA), binocular uncorrected intermediate visual acuity (UIVA) at 60 cm, binocular uncorrected near visual acuity (UNVA) at 40 cm, spherical equivalent (SE) refraction, defocus curves, mesopic and photopic contrast sensitivity, halometry, posterior capsule opacification (PCO), and responses to a patient questionnaire...

BACKGROUND: To estimate the depth of field (DOF) achievable with multi-and monofocal intraocular lenses (IOLs) and compare with actual measurements of DOF in cases implanted with a trifocal IOL and biconvex monofocal IOL METHODS: I) Computer simulations were produced to describe the relationship between DOF, pupil size, preoperative ametropia, and retinal blur tolerance limit for a model eye implanted with either multi- or monofocal IOLs. II) Monocular DOF and pupil size were measured under distance viewing conditions between 3 and 6 months postoperative following uneventful cataract surgery...

PURPOSE: The visual performance of monofocal, bifocal, and trifocal intraocular lenses was evaluated by human individuals using a vision simulator device. This allowed investigation of the visual impression after cataract surgery, without the need actually to implant the lenses. METHODS: The randomized, double-masked, three-way cross-over study was conducted on 60 healthy male and female subjects aged between 18 and 35 years. Visual acuity (Early Treatment Diabetic Retinopathy Study; ETDRS) and contrast sensitivity tests (Pelli-Robson) under different lighting conditions (luminosities from 0...

PURPOSE: To assess photopic and mesopic vision in patients implanted with 2 different trifocal intraocular lenses (IOLs). METHODS: Fifty patients with cataract in both eyes had surgery with bilateral implantation of a trifocal FineVision (FV, n = 25) or AT LISA tri 839MP (LisaTri, n = 25) IOL. Three months after surgery, high-contrast photopic uncorrected distance visual acuity and corrected distance visual acuity (CDVA) were determined using the Early Treatment Diabetic Retinopathy Study test...

PURPOSE: To compare visual outcomes, rotational stability, and centration in a randomized controlled trial in patients undergoing cataract surgery who were bilaterally implanted with two different trifocal intraocular lenses (IOLs) with a similar optical zone but different haptic shape. METHODS: Twenty-one patients (42 eyes) with cataract and less than 1.50 D of corneal astigmatism underwent implantation of one FineVision/MicoF IOL in one eye and one POD FineVision IOL in the contralateral eye (PhysIOL, Liège, Belgium) at IOA Madrid Innova Ocular, Madrid, Spain...

PURPOSE: To compare the visual performance in patients implanted with different modern multifocal intraocular lens (mfIOL) models using defocus curves. METHODS: This prospective, interventional, comparative, nonrandomized consecutive series of cases included 60 patients (45-87 years) who underwent binocular cataract surgery. Patients were divided into 4 groups depending on the intraocular lens (IOL) implanted after cataract surgery: group A, 15 patients with AT LISA tri 839MP IOL (Carl Zeiss Meditec); group B, 15 patients with FineVision trifocal IOL (PhysIOL); group C, 15 patients with ReSTOR SN6AD1 bifocal IOL (Alcon); and group D, 15 patients with Acri...
