Background: To prospectively evaluate binocular visual outcomes after implantation of trifocal intraocular lenses (IOLs) with high-water-content hydrophobic acrylic material in Japanese patients.
Methods: In 59 patients (mean age 65.1 ± 7.
Article Synopsis
- - The study aimed to compare how different intraocular lenses (EDoF vs. monofocal) affect visual acuity and contrast sensitivity in patients with primary open-angle glaucoma (POAG).
- - 46 eyes from patients with controlled POAG were examined post-surgery to assess the impacts of perimetry parameters on visual capabilities, using various measurements such as corrected distance visual acuity and contrast sensitivity.
- - Results showed that EDoF IOLs were linked to better high spatial frequency contrast sensitivity compared to monofocal IOLs, highlighting differences in visual function based on the type of lens used.
Purpose: To compare the quality of images of gratings placed in a model eye viewed through an extended depth of focus (EDoF) intraocular lens (IOL) to that of diffractive bifocal IOL or monofocal IOL.
Design: Experimental laboratory investigation.
Methods: Nondiffractive wavefront shaping EDoF (CNAET0, Alcon Laboratories), echelette-designed EDoF (ZXR00V, Johnson & Johnson Vision), diffractive bifocal IOL with low power addition (SV25T, Alcon Laboratories), or monofocal IOL (CNA0T0, Alcon Laboratories) was placed in a fluid-filled model eye.
Purpose: To evaluate the effectiveness and safety of the AcrySof IQ PanOptix toric intraocular lens (IOL) with cylinder power of 1.0 D (TFNT20) in a Japanese population with low corneal astigmatism and compare with historical control data for nontoric IOLs.
Setting: Tokyo Dental College Suidobashi Hospital, Tokyo, Japan.
Background: To prospectively evaluate visual functions and patient satisfaction after bilateral implantation of diffractive continuous depth-of-focus intraocular lens (CDF IOL) compared with trifocal IOLs.
Methods: This investigator-initiated study was approved by a certified local review board (registered: jRCTs032210305). CDF IOL (Synergy, J&J, group S) and trifocal IOL (AcrySof PanOptix, Alcon, group P) were implanted bilaterally in 30 patients each.
Introduction: The aim of this prospective study was to compare the visual functions of extended depth-of-focus intraocular lenses (EDOF IOLs) and monofocal IOLs in eyes with mild to moderate primary open-angle glaucoma (POAG).
Methods: Cataractous eyes with POAG controlled using medical treatments, no central visual field defects, and mean deviation (MD) values of -10 dB or better on the 30-2 test grid of the Swedish Interactive Threshold Algorithm standard program were included. Twenty-two eyes of 22 patients received EDOF IOLs (ZXR00V and ZXV150-375; J&J), whereas 24 eyes of 24 patients received monofocal IOLs (ZCB00V and ZCV150-375; J&J).
During cataract surgery, the intraocular temperature changes when irrigating low-temperature fluid and ophthalmic viscosurgical devices (OVDs) are inserted in the anterior chamber, and such a temperature variation affects the unfolding of the intraocular lens (IOL). A porcine eye holder was developed for simulating temperature conditions in clinical surgery by maintaining the ocular temperature close to the body temperature. An aluminum holder was designed to fit porcine eyes and maintain the ocular temperature at approximately 36 °C, while surgery was performed at a room temperature of 20 °C.

Patients And Methods: This pooled analysis included adult patients from six prospective clinical studies performed across 56 centers worldwide. After cataract removal by phacoemulsification, all patients were implanted with TFNT00; follow-up duration varied from 3 to 12 months according to the studies' design.
Purpose: Implantation of presbyopia-correcting intraocular lenses (IOLs) has not been advised for glaucomatous eyes because of the risk of decreased contrast sensitivity with progress of glaucoma. Extended depth-of-focus (EDF) IOLs have been reported to provide comparable postoperative visual function and influence on the visual field to monofocal IOLs.
Methods: This case series was a retrospective medical record review of 16 eyes of 10 patients who had normal tension glaucoma (NTG) with no central visual field defects and underwent cataract surgery with implantation of diffractive EDF IOLs.
Evaluations of bridging sutures in preventing iris capture in eyes with intrascleral fixation of implanted intraocular lens.
Graefes Arch Clin Exp Ophthalmol
February 2023
Purpose: The study aims to determine the effectiveness of bridging sutures in preventing iris capture and a subsequent reverse pupillary block after an intrascleral fixation of an implanted intraocular lens (IOL).
Methods: We studied 6 eyes that had an iris capture with reverse pupillary block due to a dislocated IOL after an intrascleral fixation. After the dislocated IOL was repositioned, 10-0 polypropylene sutures were inserted 1.
Article Synopsis
- The study aimed to compare the image quality seen through an extended depth of focus (EDF) intraocular lens (IOL) against multifocal and monofocal IOLs.
- Using a model eye that mimicked human corneal aberrations, the researchers recorded the images through various lens types and compared their contrasts.
- Results indicated that images viewed through the EDF IOL were clearer than those seen through multifocal IOLs, especially when using a wide-angle contact lens, suggesting better visibility for surgeons in certain procedures.
Article Synopsis
- The study assesses the effectiveness of femtosecond laser-assisted capsulotomy in different levels of zonular dehiscence using an eye model.
- The experiment compared outcomes from laser-assisted capsulotomies to manual methods, revealing that the laser technique maintained better capsulotomy continuity and reduced decentration in cases with up to 180 degrees of zonular dehiscence.
- Findings suggest that femtosecond laser techniques may be preferable for cataract surgeries involving zonular instability, offering insights for clinical decision-making.
Purpose: To evaluate differences in subjective and objective refractions in eyes with extended-depth-of-focus intraocular lenses (EDOF IOLs) using echelette optics, and the effect of the light wavelength used during examinations.
Methods: In the prospective study, subjective and objective refractions of 128 eyes of 64 patients were examined 3 months after implantation of the EDOF IOLs (ZXR00V, Johnson & Johnson Surgival Vision). Objective refractions were measured using an autorefractor with a near-infrared (NIR) light source.
The prospective comparative case series aimed to evaluate the binocular uncorrected visual acuities (BUCVAs) after staged implantations of extended-depth-of-focus intraocular lenses (EDOF IOLs) targeting emmetropia and -0.5 diopter (D). Diffractive EDOF IOLs with an add power of +1.

Article Synopsis
- The study aimed to assess the degree of zonular weakness by observing lens movement during continuous curvilinear capsulorhexis (CCC) and to create a classification system for it.
- The research was conducted at Kozawa Eye Hospital in Japan, analyzing 402 eyes from patients who underwent cataract surgery procedures.
- The findings showed that most eyes exhibited Grade I weakness (68.6%), with an increase in the severity of zonular weakness correlating with greater use of stabilization devices during surgery.
Purpose: To assess the clinical outcomes of currently used refractive surgery procedures performed in 2015.
Design: Prospective, multicenter cohort study.
Methods: This prospective study included 15 011 eyes of 7622 consecutive patients who underwent laser in situ keratomileusis (LASIK), surface ablation, refractive lenticule extraction (ReLEx), or phakic intraocular lens (IOL) implantation at 42 major institutions.

Purpose: To evaluate the visual performance in eyes with diffractive intraocular lenses (IOLs) after laser in situ keratomileusis (LASIK).
Methods: This single-center retrospective study evaluated eyes that had diffractive multifocal IOL implantation after previous LASIK or not treated with LASIK (controls). The outcomes' measures were the visual acuities (VAs) at distance and near, spherical equivalent (SE) and contrast sensitivity at one month postoperatively.
