PURPOSE: To characterize corneal biomechanical properties using the CORVIS-ST device in myopic individuals. METHODS: This prospective cross-sectional study included patients with myopia. Our study included 154 eyes of 154 myopic patients aged between 18 and 40 years, with stable refraction for at least 2 years. A full ophthalmological examination and corneal tomography were performed using a Pentacam HR device. Corneal biomechanical parameters were assessed using the CORVIS-ST device in mild, moderate, severe, and extreme myopia groups...

PURPOSE: To evaluate the refractive prediction error in flanged intrascleral intraocular lens (IOL) fixation using the SRK/T formula and compare the axial length using a single IOL. METHODS: Seventy-six eyes from 70 patients (45 males and 25 females) were included in this study. The mean age at the time of surgery was 73.4 ±12.3 years. The patients underwent flanged IOL fixation using a PN6A (Kowa). All surgeries were performed by two surgeons (Y. K. and T...

INTRODUCTION: Corneal ectasia leads to progressive irregular corneal curvature and reduced visual acuity. OBJECTIVE: To assess the safety and effectiveness of corneal collagen cross-linking (CXL) for managing corneal ectasia resulting from refractive laser surgery (RSL). METHODS: A systematic review and meta-analysis were realized according to PRISMA guidelines. We searched PubMed, EMBASE, Cochrane, and Web of Science databases for studies on CXL in patients with ectasia after RLS...

PURPOSE: To report the outcomes of a novel microwave heating device (Blepha EyeBag® ) used serially for the treatment of meibomian gland dysfunction (MGD). PATIENTS AND METHODS: This prospective single center study was conducted at University Magna Graecia of Catanzaro. Patients were instructed to apply the compress twice daily for 15 days and once per day every two days, as reported in the package insert. Outcome measures were i) ocular surface disease index (OSDI) score, ii) tear meniscus height (TMH), iii) non-invasive keratograph break-up time (NIKBUT) (first and average), iv) meiboscore, v) bulbar redness...

PURPOSE: Many physicians charge more than the Medicare insurance program pays. Current charge-to-payment ratios in ophthalmology and trends over the years are unknown. In this work, we examined physician charge-to-payment ratios in ophthalmology across procedures and consultations. METHODS: We utilized data from 100% final-action physician/supplier Part B Medicare fee-for-service (FFS) population from 2015 to 2020. We retrieved data on ophthalmic procedures and consultations, both facility-based and non-facility-based, conducted by ≥ 50 ophthalmologists...

BACKGROUND: Seeking a quick way to estimate refractions for challenging pediatric patients, we studied two non-contact methods with particular attention to accuracy and level of stress in uncovering cycloplegic hyperopia. METHODS: Newly referred and follow-up pediatric eye patients had timed school bus accommodation-relaxing skiascopy (SBARS) and Plusoptix A12 (Px) photoscreener testing before cyclopentolate 1% confirmatory examinations. The ABCD ellipsoid univariate method based on relative blur and vector components was used to compare dry sphero-cylinder refraction estimates with cycloplegic...

INTRODUCTION: To evaluate eye and orbital injuries in non-powered scooter, electric-scooter (e-scooter), and hoverboard riders in the United States (US) between 2014 and 2019. METHODS: The National Electronic Injury Surveillance System (NEISS) was queried for head and neck injuries by body part codes related to non-powered scooters and powered scooters/hoverboards from 2014 to 2019. The NEISS complex sampling design was used to obtain US population projections of injuries and hospital admissions...

PURPOSE: This study aimed to compare the surgical outcome of inferior oblique myectomy, IOM versus inferior oblique recession-anteriorization, IORA in the treatment of inferior oblique overaction, IOOA. PATIENTS AND METHODS: A retrospective chart review was performed over a 12-year period, from 2009 to 2021. Eighty-nine patients diagnosed with IOOA who underwent IOM or IORA were included. The primary outcome was postoperative residual IOOA (grade 0 to +4) and percentage favorable outcome, defined as IOOA grade ≤1+ at 6 months post operation, in each group...

PURPOSE: To evaluate if chloroprocaine ophthalmic gel 3% acts as a barrier to the bactericidal actions of povidone-iodine (PVI) which has been seen in other higher viscosity gel anesthetics. METHODS: This was a single site, prospective, randomized, patient-masked study evaluating the effects of preservative-free chloroprocaine ophthalmic gel 3% (IHEEZO® , Harrow, Nashville, TN) compared with tetracaine ophthalmic solution 0.5% and their effects on the bactericidal action of povidone-iodine 5%...

PURPOSE: To investigate the impact of vergence dysfunction on myopia progression in children with Defocus incorporated multiple segments (DIMS) spectacle lenses. PATIENTS AND METHODS: We retrospectively enrolled children prescribed DIMS spectacle lenses to slow myopic progression. Baseline vergence dysfunction was determined according to phoria at distance and near. Axial length (AL) measurement and cycloplegic subjective refraction were performed before fitting the lenses and at six-month and one-year follow-ups...

Pythium insidiosum, an Oomycete, causes severe keratitis that endangers vision. Its clinical, morphological, and microbiological characteristics are often indistinguishable from those of fungal keratitis, earning it the moniker "parafungus". Distinctive clinical hallmarks that set it apart from other forms of keratitis include radial keratoneuritis, tentacles, marginal infiltration, and a propensity for rapid limbal spread. The therapeutic approach to Pythium keratitis (PK) has long been a subject of debate, and topical and systemic antifungals and antibacterials have been tried with limited success...

BACKGROUND: Trachoma is a serious public health concern and cause of blindness globally. Despite its vulnerability to all ages, children are more vulnerable to its adverse outcomes and devastating complications. This study assessed the magnitude of trachoma among children in host and refugee communities in Gambella, Ethiopia. METHODS: A community-based comparative survey was done among 743 participants. Multistage sampling technique was used to select participants...

PURPOSE: To determine which donor characteristics, like previous diseases and surgeries, influence the severity of the DM/endothelial lamella preparation prior to DMEK-surgery. PATIENTS AND METHODS: Retrospective cross-sectional single-center study is presented. Eight hundred and forty-six eyes with DMEK-surgery between 01/2018 and 01/2021 performed at the University Hospital Cologne, Germany, were included. Information regarding the donors' previous diseases and surgeries were provided by a large database of a cornea bank (Multi Tissue Bank Mecklenburg-Vorpommern) and merged with the Cologne DMEK database, which contains information regarding preparation characteristics of the surgeon-prepared graft directly preoperatively...
