Trifocal lenses and cataracts

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)...

PURPOSE: To determine the visual and refractive outcomes of trifocal toric intraocular lens (IOL) implantation in Asian eyes with cataract and astigmatism. SETTING: Asian Eye Institute, Makati City, Philippines. DESIGN: Prospective study. METHODS: 187 eyes were implanted with the FineVision POD FT IOL and followed for 2 years. The measurements included subjective refraction, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), distance-corrected intermediate visual acuity (DCIVA), uncorrected near visual acuity (UNVA), distance-corrected near visual acuity (DCNVA), defocus curve, photopic and mesopic contrast sensitivity, and rotational stability...

PURPOSE: To evaluate the efficacy of a new visual training program for improving the visual function in patients implanted with trifocal intraocular lenses (IOLs). METHODS: Randomised placebo-controlled clinical trial enrolling 60 subjects (age, 47-75 years) undergoing cataract surgery with implantation of trifocal diffractive IOL. Home-based active visual training was prescribed immediately after surgery to all of them (20 sessions, 30 min): 31 subjects using a serious game based on Gabor patches (study group) and 29 using a placebo software (placebo group)...

In this retrospective case series, we examine the outcomes of diffractive trifocal intraocular lens implantation after cataract surgery, in patients with subclinical and forme fruste keratoconus. Eight eyes of four patients (aged between 47 and 64) were included in the study and underwent phacoemulsification with implantation of AT LISA tri 839MP or AT LISA tri-toric 939MP intraocular lenses (Carl Zeiss Meditec AG, Jena, Germany). Post-operative evaluation included a visual acuity test at three distances (6m, 80cm, and 40cm), a visual acuity test at three low contrast levels (25%, 12...

OBJECTIVES: To compare the subjective and objective visual quality more comprehensively after surgery of the commonly used multifocal intraocular lenses (IOL) and monolocal IOL implants through long-term systematic clinical observation, providing reference and basis for clinical application. METHODS: Non-randomized controlled trial. A total of 91 (138 eyes) patients between June 2020 and December 2020 were implanted trifocal IOL or monofocal IOL after phacoemulsification in a tertiary class hospital in Wuhan...

A 61-year-old man presented with gradual blurring of vision and glare in both eyes for a couple of years, with worsening of the vision in his right eye over the past 2 months. He had no medical history of note. On clinical examination, his visual acuities were 20/80 in the right eye and 20/30 in the left eye, uncorrected. The cornea was clear, and the anterior chamber (AC) was deep in both eyes. He had bilateral mild nuclear sclerosis with round central onion-ring-like posterior opacities. The opacities measured approximately 2 mm in diameter and were marginally larger in the right eye than in the left eye (Figure 1JOURNAL/jcrs/04...

INTRODUCTION: Refractive lens exchange (RLE) patients represent a unique population with a different baseline and set of expectations compared to their cataract counterparts. Visual outcomes and patient satisfaction following RLE with bilateral implantation of a trifocal intraocular lens (IOL) were assessed in a cohort of patients with presbyopia and without cataract. METHODS: Charts of patients with presbyopia who underwent femtosecond laser-assisted RLE with bilateral implantation of the PanOptix trifocal IOL (toric and non-toric) at a single-surgeon, private practice center from September 2019 to August 2020 were retrospectively reviewed...

Presbyopia correction through implantation of a trifocal intraocular lens (IOL) is a modality offered to both cataract and refractive-lens exchange patients. To maximize postoperative satisfaction, IOL selection needs to be made based on patients' requirements aligned with the available technology. Five Trifocal IOLs were assessed in this study, and their differentiating features were identified: Triumf POD L GF, AT Lisa Tri, Tecnis Synergy, AcrySof IQ PanOptix, and Acriva Trinova Pro C. The optical quality was assessed using the modulation-transfer-function principle...

This study aimed to evaluate the quality of life and the satisfaction level of Brazilian and Chinese patients who underwent cataract surgery for Acysof IQ PanOptix Model TFNT00 (Alcon Laboratories, Fort Worth, TX, USA) implantation. This retrospective study enrolled 51 patients from China and 51 patients from Brazil. At the 3-month follow-up, uncorrected distance visual acuity (UDVA) at 5 m, uncorrected intermediate visual acuity (UIVA) at 60 cm, and uncorrected near visual acuity (UNVA) at 40 cm were evaluated; Catquest 9SF and the Near Activity Visual Questionnaire (NAVQ) were administered to the patients...

PURPOSE: To assess the influence of capsular tension ring (CTR) on surgical outcomes of trifocal intraocular lens (IOL) implantation in femtosecond laser-assisted cataract surgery. SETTING: Sugita Eye Clinic, Tokyo, and University of Tsukuba, Ibaraki, Japan. DESIGN: Prospective, randomized, paired-eye clinical study and laboratory study. METHODS: In the clinical study involving 44 eyes of 22 patients with no risk of zonular instability, 1 eye received IOL alone and the contralateral eye received IOL with CTR...

PURPOSE: To compare the postoperative visual outcomes and quality of vision obtained with 2 types of diffractive trifocal intraocular lenses (IOLs) in patients with highly myopic cataracts. DESIGN: Prospective, multicenter, randomized controlled trial. METHODS: Patients with high-myopic cataracts were randomized to binocular implantation of either the TFNT00 (n = 27) or the 839 MP (n = 28) trifocal IOLs at 3 surgery centers in China and were followed up for 1 year...

The prevalence of high myopia is rising globally. In addition to an increased risk of retinal detachment, high myopia is associated with earlier cataract formation. Patients with myopia are also often more motivated to become spectacle-independent after a lens procedure. However, the use of multifocal intraocular lens (MfIOL) remains controversial for patients with extreme myopia, which is classified as patients with an axial length >28 mm. Here, we present the case of a 64-year-old patient with visually significant cataract and extreme axial myopia >31 mm in both eyes who desired to be spectacle-independent...

INTRODUCTION: A systematic literature review and meta-analysis was conducted to identify and obtain a precise single summary estimate on complete spectacle independence after bilateral implantation of a trifocal intraocular lens (IOL) (AcrySof PanOptix, TFNTXX/TFATXX) for patients undergoing cataract surgery. METHODS: A search was conducted in PubMed from January 2017 to September 2021. Relevant congress presentations were also searched to include data from completed studies not yet published...

PURPOSE: To report the visual outcomes and quality of vision and life after bilateral implantation of a single-piece trifocal intraocular lens in Chinese patients. SETTING: Hong Kong Sanatorium & Hospital. DESIGN: Prospective, observational case series. METHODS: Patients with bilateral implantation of AcrySof IQ PanOptix multifocal intraocular lens (Alcon Laboratories Inc.) were included. Distance, intermediate (60 cm), and near (40 cm) visual acuities (VA) and contrast sensitivity, defocus curve, preoperative higher-order aberration (HOA), dysphotopsia (0-5), satisfaction (1-5), spectacle independence, and quality of life were evaluated...

BACKGROUND: Presbyopia occurs when the lens of the eyes loses its elasticity leading to loss of accommodation. The lens may also progress to develop cataract, affecting visual acuity and contrast sensitivity. One option of care for individuals with presbyopia and cataract is the use of multifocal or extended depth of focus intraocular lens (IOL) after cataract surgery. Although trifocal and bifocal IOLs are designed to restore three and two focal points respectively, trifocal lens may be preferable because it restores near, intermediate, and far vision, and may also provide a greater range of useful vision and allow for greater spectacle independence in individuals with presbyopia...

PURPOSE: To compare visual performance and quality of life (QOL) following bilateral implantation of a novel non-diffractive extended depth-of-focus (EDOF) intraocular lens (IOL) and a trifocal IOL. SETTING: University Faculty of Medicine, Department of Ophthalmology, Ankara, Turkey. DESIGN: Prospective comparative interventional case series. METHODS: Hundred and four eyes of 52 cataract patients, bilaterally implanted with a non-diffractive EDOF IOL or a trifocal IOL were included...

PURPOSE: Trifocal Intraocular Lenses (IOLs) were developed to provide patients with effective near, intermediate and distance vision, thus minimizing spectacle dependency. Residual astigmatism has previously been shown to impact unaided visual acuity across all distances; therefore, to optimise the expected outcomes, consideration of preoperative corneal astigmatism is essential. The purpose of this study was to provide a real-world, multi-site review of visual and refractive outcomes in eyes undergoing implantation with the Panoptix Trifocal toric IOL platform...
