Article Abstract
Background: This study aimed to compare visual results following the implantation of two distinct diffractive trifocal IOLs utilizing various vision evaluation techniques and subjective satisfaction.
Methods: The study included 32 eyes receiving AcrySof IQ PanOptix implantation and 32 receiving AT LISA tri 839 MP. Post-operative examination at one year included uncorrected visual acuity (UCVA), distance-corrected visual acuity (DCVA) at 4 m, 80 cm, 60 cm, and 40 cm, Contrast sensitivity under photopic and mesopic conditions, and a questionnaire on subjective quality of vision, optical phenomena, and spectacle independence.
Results: The two groups were similar in baseline demographics, pre-operative visual, biometric data (except for axial length), and surgical paraments. The PanOptix outperformed the AT LISA tri in the intermediate range when using the standard visual acuity testing (UCVA: 0.23 ± 0.14 logMAR vs. 0.31 ± 0.17 logMAR, p = 0.04; BCVA: 0.21 ± 0.12 vs. 0.28 ± 0.14, p = 0.03) and in the intermediate and far range when using the interactive computer program (intermediate: UNVA "E" optotype test: 0.05 ± 0.12 vs. 0.12 ± 0.13, p = 0.03; Far: UNVA "E" optotype: 0.07 ± 0.12 vs. 0.13 ± 0.10, p = 0.05). In addition, the PanOptix group had higher contrast sensitivity under photopic and mesopic conditions with and without glare at all spatial frequencies. There was no difference in subjective outcomes between the groups.
Conclusions: Patients who received PanOptix IOL had better visual outcomes for intermediate and far with higher contrast sensitivity under various conditions. Based on patients ' needs and demands, these results could support discussion when tailoring the optimal multifocal IOl.

Assessment of Diffractive Intraocular Lenses Using Near-Infrared Light: A Critical Evaluation.
Transl Vis Sci Technol
June 2025
Department of Ophthalmology, Rostock University Medical Center, Rostock, Germany.
Purpose: After cataract surgery, near-infrared (NIR) light-based optical devices are commonly used for in vivo vision quality assessment, using wavefront sensors and double-pass techniques. This study investigates the diffraction efficiencies and orders of the AT LISA tri 839MP (Carl Zeiss Meditec AG, Berlin, Germany) under visible and NIR illumination, highlighting challenges in using NIR-based devices to evaluate diffractive intraocular lenses (IOLs).
Methods: This study uses an optical bench system to generate in vitro through focus intensity data and compares the results to an optics simulation using the manufacturer's theoretically designed diffractive surface topography of the investigated trifocal IOL instead of possibly error-prone measured topography data.
Neurosensory binocular vision after bilateral implantation of an extended depth of focus intraocular lens with micro-monovision: a prospective cohort study.

Department of Ophthalmology, Peking University Third Hospital, Beijing, China.
Background: The goal of this study was to evaluate the presbyopia-correcting performance, binocular visual quality and neurosensory binocular vision of bilateral implantation of an extended depth of focus (EDOF) intraocular lens (IOL) with micro-monovision and compare this IOL with two multifocal IOLs.
Methods: This prospective cohort study enrolled patients with bilateral implantation of diffractive EDOF IOL (Tecnis Symfony ZXR00, Abbott Medical Optics, Inc.), diffractive trifocal IOL (AT LISA tri 839MP, Carl Zeiss Meditec AG) and refractive rotationally asymmetric bifocal IOL (SBL-3, Lenstec, Inc.

Rationale: The purpose of this study was to present the long-term outcomes of a monobloc multifocal intraocular lens (IOL) (ZEISS LISA tri 839MP) with a missing haptic segment in a patient with high myopia.
Patient Concerns: A 51-year-old female with high myopia presented for cataract surgery.

Purpose: To compare the visual outcomes of simple high myopia (HM) and mild pathologic myopia (PM) following implantation of a trifocal intraocular lens (IOL), and investigate the influence of fundus structures.
Methods: We retrospectively studied 63 high myopic eyes of 63 patients underwent femtosecond laser-assisted cataract surgery with implantation of AT LISA tri 839MP IOL (Carl Zeiss Meditec AG, Germany) between July 2020 and September 2024. 34 eyes in the HM group and 29 eyes in the PM group.

Background: To investigate the impact of central corneal astigmatism on postoperative visual outcomes in patients with trifocal intraocular lens (IOL) implantation.
Methods: This retrospective study included 278 eyes of 278 patients who underwent uneventful cataract surgery with implantation of the trifocal IOL (AT LISA tri 839MP). Patients were divided into two groups according to the total corneal refractive power (TCRP) in 3 mm zone centered on the corneal apex: low astigmatism group, TCRP ≤ 0.
