Background/objectives: To evaluate the refractive outcomes, optical performance, and the quality of vision in patients implanted with a new diffractive intraocular lens (IOL), the Intensity Hanita.
Subjects/methods: This observational, prospective, longitudinal study included 64 eyes underwent bilateral cataract surgery with the Intensity IOL (Hanita Israel) implantation. Main outcome measures after 6 months were the following visual acuities (VAs) of uncorrected and corrected distance (UDVA and CDVA), uncorrected and distance corrected intermediate VAs (UIVA and DCIVA), uncorrected and distance corrected near (UNVA and DCNVA), refraction, slitlamp biomicroscopy, defocus curve (DFC), high ocular aberrations (HOA), contrast sensitivity (CS), optical quality, subjective quality of vision (QoV) and near activity visual questionnaires (NAVQ).
Purpose: To manage patient dissatisfaction following multifocal intraocular lens (MF-IOL) implantation by IOL exchange with either a monofocal or an alternative MF-IOL, and to compare outcomes in these two groups.
Methods: MF-IOL exchange was performed in 32 patients (64 eyes) with neuroadaptation failure. The MF-to-MF group involved patients who had a MF-IOL exchanged with another MF-IOL of a different optical profile and the MF-to-MO group involved patients who had a MF-IOL exchanged to a monofocal IOL.
Purpose: To evaluate clinical retinal optical image quality following implantation of an extended depth of focus intraocular lens (EDOF IOL) (Vivity; Alcon Laboratories, Inc), and to compare it with a monofocal and a trifocal IOL.
Methods: This prospective, comparative, case-control study included 88 eyes implanted with: (1) 19 monofocal IOLs (AcrySof SA60AT; Alcon Laboratories, Inc); (2) 38 EDOF IOLs (AcrySof IQ Vivity); and (3) 31 trifocal IOLs (AT LISA tri 839MP; Carl Zeiss Meditec AG). Total root mean square, ocular lower (LOA) and higher (HOA) order aberrations, point spread function (PSF) Strehl ratio (PSF with LOA), and PSF Strehl ratio excluding LOA (PSF without LOA) were analyzed using a Pyramidal WaveFront-based sensor aberrometer Osiris (Costruzione Strumenti Oftalmici) at two different pupil sizes (3 and 4 mm).
Efficacy, predictability and safety of long-term orthokeratology: An 18-year follow-up study.
Cont Lens Anterior Eye
February 2022
Purpose: To determine the efficacy, predictability and safety of long-term orthokeratology in children and adults.
Methods: Case histories of 300 orthokeratology patients (596 eyes; 34.3% children; 65.
Purpose: To evaluate the clinical and visual outcomes, quality of near vision and the influence of photic phenomena in patients bilaterally implanted with a new Precizon Presbyopic multifocal intraocular lens (IOL).
Methods: In this prospective consecutive case series, 20 eyes of 10 patients were included (mean age 63.80 ± 12.
Objective: To evaluate and compare the objective and subjective outcomes after the bilateral implantation of a diffractive bifocal and trifocal intraocular lens.
Methods: This is a case-control, single-center observational study which included 27 patients; 16 patients were implanted bilaterally with the bifocal AcrySof IQ ReSTOR+3.0D and 11 patients with the trifocal AT LISA tri 839MP.
Article Synopsis
- - The study investigates three unreported families with punctiform and polychromatic pre-Descemet corneal dystrophy (PPPCD), examining clinical features and genetic factors associated with the condition.
- - Researchers performed extensive ocular assessments, whole exome sequencing, and Sanger sequencing, identifying a significant increase in corneal stiffness and two specific genetic variants linked to PPPCD across the families.
- - Findings suggest that PPPCD affects corneal biomechanics and is linked to a novel variant in the PRDX3 gene; further screening of additional families is needed to explore the genetic complexity of the disorder.
Purpose: The aim of this study is to analyze the long-term stability of the corneal topography, the functional optical zone, and the refractive stability throughout 3 years following laser in situ keratomileusis surgery for hyperopia using a 500-Hz excimer laser system.
Methods: This retrospective consecutive observational case series study comprised 66 eyes that underwent laser in situ keratomileusis to correct hyperopia with a postoperative follow-up of 3 years. Laser in situ keratomileusis procedures were performed using the SCHWIND Amaris 500-Hz excimer laser.
Purpose: To evaluate clinical and visual outcomes, quality of near vision, and intraocular optical quality of patients bilaterally implanted with a trifocal PanOptix intraocular lens.
Methods: In this prospective consecutive case-series study, 52 eyes of 26 bilateral patients (mean age, 60.2 ± 7.
Purpose: To evaluate the long-term visual, refractive, and corneal aberrometric outcomes and regression of the achieved correction of hyperopia with a sixth-generation excimer laser.
Methods: This retrospective, consecutive, observational case series study comprised 86 eyes of 44 patients who underwent LASIK to correct hyperopia with a postoperative follow-up of 3 years. LASIK procedures were performed using the sixth-generation Amaris excimer laser (Schwind eye-tech-solutions GmbH and Co.
