Trifocal lenses and cataracts

OBJECTIVES: To evaluate the clinical results of a new trifocal intraocular lens (IOL) with sinusoidal design by comparing with a traditional trifocal IOL. MATERIALS AND METHODS: A total of 79 patients undergoing uneventful microincisional cataract surgery with bilateral implantation of one of two types of trifocal IOLs, the Acriva Trinova IOL (VSY) or Acrysof IQ PanOptix IOL (Alcon), were enrolled in this prospective study. Visual and refractive outcomes, contrast sensitivity (CS), and defocus curve were assessed at 3 months after surgery...

To evaluate the visual performance of a diffractive bifocal intraocular lens (IOL) with + 4.0 D near addition (ZMB00) and a diffractive trifocal IOL with + 2.17 D and + 3.25 D near addition (AcrySof IQ PanOptix TFNT00), we investigated the 10-week postoperative parameters after cataract surgery in which ZMB00 or TFNT00 lenses were implanted bilaterally from 2011 to 2020 (with a 3-month interval between implantation of the right and left lenses). The study included 1448 eyes of 724 patients...

PURPOSE: Evaluate postoperative visual performance in patients with bilaterally implanted AT LARA or AT LARA/AT LISA tri (Carl Zeiss AG, Jena, Germany) intraocular lenses. METHODS: Multicentered, comparative, open-label, retrospective/prospective study. Post-IOL implantation, patients were prospectively enrolled into this study; preoperative patient data were collected retrospectively. Follow-up was at 2-4 and 5-8 months post-surgery. The primary endpoint was binocular best corrected distance visual acuity (CDVA)...

PURPOSE: Optical properties of commonly used multifocal and extended-depth-of-focus (EDOF) intraocular lenses (IOLs) can induce artifacts or changes in optical coherence tomography (OCT) measurements. Our purpose was to investigate the possible effects of different IOLs on peripapillary and macular OCT parameters. METHODS: The preoperative and postoperative third-month peripapillary OCT and ganglion cell analysis (GCA) parameters of patients having monofocal (Alcon IQ), multifocal (PanOptix), or EDOF (Vivity) IOL implanted during cataract surgery were compared...

PURPOSE: To objectively quantify glare of intraocular lenses (IOLs) utilizing a diffractive principle to extend visual range. To identify models with increased susceptibility to inducing glare. SETTING: David J Apple Laboratory, Heidelberg, Germany. DESIGN: Laboratory investigation. METHODS: Glare was assessed by means of straylight parameter with a standard C-Quant (Oculus GmbH) intended for 7°. In addition, two C-Quant modifications were used to test lower angles (i...

AIM: This aims to study visual satisfaction and spectacle independence in prepresbyopic age patients with cataracts after the implantation of either monofocal intraocular lens (IOL) with enhanced intermediate vision or trifocal IOL. SETTING: Private practice. MATERIALS AND METHODS: This prospective, observational case study was conducted on patients in the prepresbyopic age group with cataracts. Patients were allocated to one of the two groups...

BACKGROUND: To assess whether a trifocal intraocular lens (IOL) with neutral spherical aberration (SA) provides better visual and refractive outcomes than a trifocal IOL with negative SA after hyperopic corneal laser ablation. METHODS: This is a retrospective comparative study. Patients were classified according to the IOL implanted after cataract or clear lens phacoemulsification [group 1, PhysIOL FineVision Pod-F (negative SA); group 2, Rayner RayOne Trifocal (neutral SA)]...

AIM: To compare the postoperative binocular visual performance with an iTrace analyzer following femtosecond laser-assisted cataract surgery (FLACS) combined with bilateral implantation of two different types of diffractive trifocal intraocular lenses (IOL). METHODS: During this retrospective observational study, patients who received bilateral FLACS combined with implantation of two different types of diffractive trifocal IOLs were evaluated. According to the IOLs' different types and design, the patients were divided into AT LISA tri839MP group (tri839 group) and AcrySof PanOptix TFNT00 group (TFNT group)...

INTRODUCTION: Presbyopia-correcting intraocular lens (PCIOL) implantation is a popular treatment option for cataract surgery patients who desire spectacle independence. This study aimed to understand patient perception and outcomes with PCIOLs by analyzing patient social media posts. METHODS: This was a non-interventional retrospective study that used predefined search strings to identify publicly available social media data discussing patient perceptions and outcomes with seven PCIOLs (three trifocal, one multifocal with continuous range of vision, and three extended depth-of-focus [EDOF] PCIOLs)...

Visual difficulties can negatively impact life quality. Our purpose was to report the refractive surgical planning and outcomes of a young patient with mixed astigmatism and phacoemulsification-induced presbyopia due to congenital cataracts who was unsatisfied with her vision-related quality of life. A 32-year-old woman, submitted to phacoemulsification with implantation of a monofocal intraocular lens (IOL) and Nd:YAG laser posterior capsulotomy 3 years before, due to congenital cataracts, was referred to the Refractive Surgery Unit of Centro Hospitalar Universitário de Santo António...

INTRODUCTION: Astigmatism reduces the postoperative visual performance after non-toric intraocular lenses (IOLs) implantation, and limits the use of refractive IOLs in cataract surgery. The purpose of this study was to compare the efficacy in astigmatism correction and the postoperative visual outcomes between the implantation of a trifocal IOL with femtosecond laser-assisted arcuate keratotomy (FSAK) in one eye and a bifocal toric IOL (TIOL) in the other, in patients with cataract and moderate astigmatism...

PURPOSE: To compare the visual outcomes of bilateral implantation of two commercially available trifocal intraocular lenses (IOLs) (AcrySof IQ PanOptix IOL; Alcon Laboratories, Inc and AcrivaUD Trinova IOL; VSY Biotechnology). METHODS: This comparative, investigator-initiated, single-center randomized trial was conducted by the Department of Ophthalmology of the Medipol Mega University Hospital in Istanbul, Turkey. Adult patients were randomized in a 1:1 ratio using a block randomization program to undergo cataract surgery and receive the implantation of either the PanOptix or Trinova IOL in both eyes...

Posterior capsule opacification (PCO) is a common postoperative complication of extracapsular cataract surgery, which is caused by the proliferation and migration of lens epithelial cells and can affect long-term visual outcomes significantly. The most effective treatment for PCO is neodymium-doped yttrium aluminum garnet (Nd:YAG) laser capsulotomy; however, this treatment is associated with posterior segment complication and can break the stability of capsular bag, affecting the position and function of trifocal or toric intraocular lenses (IOLs)...
