Introduction: The aim of our study was to assess the outcome of Gore-Tex sutures in minimally invasive scleral fixation of subluxated posterior chamber intraocular lenses (PCIOLs) and to demonstrate a method for validating the lens position.

Methods: Retrospective study of patients who underwent lasso in-the-bag scleral fixation of a subluxated PCIOL using the snare technique with Gore-Tex suture from 2019 to 2021 in a single tertiary medical center. Functional outcome was analyzed by clinical assessment, and anatomical outcome, by ultrasound biomicroscopy (UBM).

Background: Accurate intraocular lens (IOL) calculation in eyes with keratoconus (KCN) poses significant challenges. While various formulas, including KCN-specific ones, have been investigated, the optimal calculation method remains inconclusive.

Methods: The study was pre-registered in PROSPERO (CRD42023483119).

Objectives: To analyse the accuracy of artificial intelligence (AI)-driven intraocular (IOL) calculation formulae, together with established formulae using the heteroscedastic methodology and the Eyetemis Analysis Tool.

Methods: Data from 404 eyes who underwent uneventful phacoemulsification with implantation of the SN60WF IOL were retrospectively reviewed. IOL power calculations were performed using the Barrett Universal II (BUII), EVO 2.

Purpose: The purpose of this study was to identify early indicators of keratoconus progression in Pentacam data using machine learning (ML) techniques.

Methods: A retrospective Pentacam tabular data set was created by retrieving 11,760 tomography tests performed in patients with keratoconus. Data for eyes labeled unstable based on their referral for cross-linking were differentiated from data for eyes labeled stable and not referred for follow-up procedures.

Purpose: To describe the placement of a silicone shield to protect the optical cylinder following osteo-keratoprosthesis or osteo-odonto-keratoprosthesis (O/OKP) procedures in four patients.

Methods: In this retrospective observational study, we reviewed all patients who underwent O/OKP in our tertiary medical centre. We found four patients in whom a protective cellphone silicone shield (VisionGuard, Zagg, Utah, USA) was cut with a 3 mm dermal punch and placed on the polymethyl methacrylate (PMMA) optical cylinder of an O/OKP 3-4 months after implantation to either correct or prevent abrasions.

Purpose: To examine the rate of ciliary body detachment in patients with choroidal detachment following glaucoma surgery and its effect on the clinical course, management, and prognosis.

Methods: A prospective observational case-series study. Patients with choroidal detachment following glaucoma surgery in 2018-2019 were included.

Corneal disease is among the leading reversible causes of blindness worldwide. Corneal transplantation is a successful and curative treatment for most of these cases. However, in certain indications it is not amendable for standard corneal transplantation, the only available option to restore functional vision is keratoprosthesis (KPro) implantation.

Purpose: Prompted by the clinical concern that limited healthcare resources allocation affects physicians' research productivity, this study examines the association between bibliometric indices of ophthalmologic research and national economic indicators in Organisation for Economic Co-operation and Development (OECD) countries.

Methods: The Scimago Journal and Country rank source was searched for research productivity data in ophthalmology among OECD countries between 1996 and 2019. Bibliometric indices included: documents number, number and percent of citable documents, citations number, citations per document, and H-index.

Article Synopsis
  • The study reviews disease-causing mutations in the BEST1 gene, correlates genotypes with phenotypes, and estimates the prevalence of Best disease in the Israeli population.
  • Over 134 patients from nine medical centers were analyzed, revealing a prevalence of 1 in 127,000, with higher rates among Arab Muslims compared to Jews.
  • Genetic testing is essential for diagnosing Best disease, as many mutations lead to autosomal-dominant inheritance and are concentrated in critical areas of the BEST1 protein that affect its normal function.*

Objective: To raise awareness of conditions that can tomographically mimic corneal ectasia and describe the actions required to avoid misdiagnosis.

Methods: We report a retrospective case series of seven patients presenting at two tertiary care centers in Israel with a presumed diagnosis of keratoconus or post-refractive ectasia. Upon further examination, the ectasia diagnosis was reconsidered and eventually ruled out.

Importance: Acute infectious conjunctivitis is a common ocular condition with major public health consequences.

Objective: To assess regional variations and microbial etiologies of acute infectious conjunctivitis to guide treatment.

Design, Setting, And Participants: In this cross-sectional study, patients with presumed acute infectious conjunctivitis were enrolled in the study at 5 sites (Honolulu, Hawaii; Los Angeles, San Francisco, and San Diego, California; and Petah-Tikva, Israel) from March 2021 to March 2023.

The study aimed to examine the effect of cataract extraction on ophthalmologists' ability to detect pseudoexfoliation (PXF) syndrome. A total of 31 patients admitted for elective cataract surgery were enrolled in this prospective comparative study. Prior to surgery, patients underwent slit-lamp examination and gonioscopy conducted by experienced glaucoma specialists.

Introduction: Preoperative measurements of apparent chord mu length above 0.6 mm have been associated with higher risks for photic phenomena after cataract surgery with multifocal intraocular lenses (MFIOLs).

Methods: This retrospective study evaluated patients scheduled for elective cataract surgery at a single tertiary medical center between 2021 and 2022.

Purpose: To compare the effect of three commonly prescribed anti-inflammatory eye drops on corneal epithelial cells in vitro.

Methods: Three different lines of human corneal epithelial cells were tested: primary cells cultured from donor tissue, commercially available primary cells, and immortalized cells. Cells were seeded on 96-well plates and treated with the following eye drops: cyclosporine 0.

Purpose: To compare the accuracy of the Barrett Integrated K (IK) toric calculator with the standard Barrett toric calculator.

Methods: Consecutive patients who underwent cataract extraction with implantation of a toric intraocular lens at the Rabin Medical Center, Israel, were reviewed. Errors in predicted postoperative refractive astigmatism were calculated for the Barrett toric calculator using biometry measurements only and with the IK tool using biometry and tomography.

Objective: To evaluate the sensitivity and specificity of the ABCD progression display for keratoconus progression.

Methods: Data was collected from patients that underwent at least two Pentacam assessments 6 months apart. Sensitivity and specificity were calculated for the ABCD progression display.

Purpose: To assess the number of recruits for military service in the Israeli Defense Force (IDF) who underwent refractive surgery prior to enlistment and examine whether the procedure affected their ability to accomplish combat training.

Setting: Medical records of IDF recruits.

Design: Retrospective analysis of medical records of recruits with ametropia who underwent or did not undergo refractive surgery prior to enlistment.

Objectives: To describe the first clinical implantation of the CorNeat™ keratoprosthesis, which utilizes a polymeric scaffold for biointegration within ocular tissue.

Methods: The CorNeat keratoprosthesis was implanted in the right eye of a patient with bilateral corneal opacification and neovascularization secondary to multiple failed grafts. The following surgical technique was used: 360 degree peritomy; epithelial scraping and corneal marking; pre-placement of three corneo-scleral sutures through the implant; central trephination using a 7 mm trephine and host cornea removal; keratoprosthesis placement and sutures tightening while fitting the corneal edge into the posterior groove of the CorNeat keratoprosthesis; and repositioning of the conjunctiva over the implant skirt and fixation with sutures and Fibrin sealant.
