Tear film stability in patients with symptoms of dry eye after instillation of dual polymer hydroxypropyl guar/sodium hyaluronate vs single polymer sodium hyaluronate.

Purpose: This study evaluated the tear film stability in patients with symptoms of dry eye after installation of dual polymer hydroxypropyl guar/sodium hyaluronate (DPHG/SH) vs single polymer SH.

Methods: Patients with recently diagnosed mild to moderate dry eye disease (OSDI score 23-32 points) were included. For each patient, the right eye was randomized to receive DPHG/SH or 0.

Does the introduction of streamlight decrease refractive surgery operating time?

Purpose: The aim of the study was to analyze the time-savings associated with introduction of Streamlight™ (Alcon Laboratories, Fort Worth, TX, USA) transepithelial photorefractive keratectomy (PRK) in surface corneal ablations.

Methods: All refractive surgeries were performed using the Alcon WaveLight® EX500 at the ArtLife Clinic, Gdańsk, Poland. The study included patients treated for refractive errors with transepithelial PRK between April 2019 and October 2021, who were matched with patients treated with alcohol-assisted PRK during the same period.

Agreement in non-cycloplegic and cycloplegic refraction between a photoscreener and a calibrated autorefractor.

Introduction: Photoscreeners have been shown to provide excellent measurements of the refractive error. However, whether they could be used for assessing cycloplegic refraction has not been examied. This study aimed to evaluate the agreement between cycloplegic and non-cycloplegic measurements obtained using a photoscreener and stationary autorefractor, respectively.

Corneal Tomography in a Commercially Available Optical Coherence Tomography Device and Comparison With a Rotating Scheimpflug Camera.

Objective: To compare the outcomes of corneal tomography obtained with an anterior-to-posterior segment optical coherence tomography device (Revo, Optopol Technologies Sp. z o.o.

Applications of the pinhole effect in clinical vision science.

The pinhole effect is commonly used to discriminate uncorrected refractive error from ocular diseases. A small aperture limits the width of light beams entering the eye, thus increasing the depth of focus. The pinhole effect has also been used in spectacles, contact lenses, corneal inlays, and intraocular lenses (IOLs) to improve reading by compensating for loss of accommodative function.

Illumination levels in commonly used ophthalmic devices.

Pupil diameter is a key parameter for corneal and multifocal intraocular lens surgery. Many devices are dedicated to measure the pupil size, but do not specify the illumination during capture. The aim of this study was to present illumination levels in routinely used ophthalmic devices which present pupil sizes.

The Prevalence of Astigmatism and Spectacle Wear in Polish Schoolchildren.

Introduction: Unilateral or asymmetric astigmatism is considered a principal refractive error leading to amblyopia and regular eye examinations should be carried out during childhood to prevent visual impairment. The aim of this study was to evaluate the prevalence of astigmatism and spectacle wear among Polish schoolchildren.

Methods: A cross sectional study was carried out in children aged 6 to 14 years old from 50 schools in Poland.

Evaluation of Ocular Diameter Parameters Using Swept-Source Optical Coherence Tomography.

To investigate the iridocorneal angle-to-angle (ATA), sclera spur-to-sclera spur (STS), and white-to-white (WTW) ocular diameters and their potential influence on anterior chamber intraocular lens (ACIOL) and implantable collamer lens (ICL) sizing in Chinese subjects by using a swept-source optical coherence tomography system (SS-OCT). A retrospective, observational, cross-sectional study. In 60 right eyes (60 subjects), the ATA, STS, and WTW were measured in six axes (0°-180°, 30°-210°, 60°-240°, 90°-270°, 120°-300°, and 150°-330°) using SS-OCT.

The prevalence of keratoconus in northern Poland: A cross-sectional study of patients from a primary healthcare practice.

Introduction: Keratoconus is defined as central and/or paracentral corneal thinning and steepening with consequent irregular astigmatism. To date, no prospective study has reported its prevalence in Central Europe. This study aimed to evaluate the prevalence of keratoconus assessed with Scheimpflug imaging in a profile of general medicine practice in Poland.

Technical failure rates for biometry between swept-source and older-generation optical coherence methods: a review and meta-analysis.

Purpose: Precise ocular measurements are fundamental for achieving excellent target refraction following both cataract surgery and refractive lens exchange. Biometry devices with swept-source optical coherence tomography (SS-OCT) employ longer wavelengths (1055-1300 nm) in order to have better penetration through opaque lenses than those with partial coherence interferometry (PCI) or low-coherence optical reflectometry (LCOR) methods. However, to date a pooled analysis showing the technical failure rate (TFR) between the methods has not been published.

The outdoor time in non-myopic children has decreased to that of myopic children during the SARS-CoV-2 pandemic.

Low levels of outdoor activity are known to be an important risk factor for the development of myopia in schoolchildren. This study aimed to determine outdoor and near work patterns in Polish schoolchildren before and during school closure due to the SARS-CoV-2 pandemic. All children undergoing a routine pediatric examination in the Elbląg branch of the Hygeia Clinic, together with their parents, were asked to fill an anonymous questionnaire.

The Effect of Blue-Light Filtering Intraocular Lenses on the Development and Progression of Glaucoma.

Prcis: Among patients who underwent uneventful cataract surgery, an advantage was seen to blue-light filtering (BLF) intraocular lenses (IOLs) in terms of glaucoma-free survival and glaucoma procedure-free survival. Among patients with preexisting glaucoma, no advantage was seen.

Purpose: To assess the effect of BLF IOLs on the development and progression of glaucoma after cataract surgery.

Association of clear vs blue-light filtering intraocular lenses with mental and behavioral disorders and diseases of the nervous system among patients receiving bilateral cataract surgery.

Purpose: To analyze new-onset mental and behavioral disorders and nervous system diseases in patients with cataract implanted with either non-blue-light filtering (BLF) or BLF intraocular lenses (IOLs) in both eyes.

Setting: Department of Ophthalmology, Kymenlaakso Central Hospital, Kotka, Finland.

Design: A retrospective registry-based cohort study of patients operated between September 2007 and December 2018 who were followed until December 2021.

Should Multifocal Intraocular Lenses Become a Standard in Phacoemulsification Cataract Surgery?

Cataracts impair daily activities such as reading, outdoor sports, and driving, which may not match best-corrected visual acuity at optimal room light conditions, but can be just as important to patients [...

Association between periodontitis and blood-ocular barrier disruption.

Purpose: Periodontitis causes low-grade systemic inflammation e.g., through circulatory periodontal endotoxins, and it has been associated with cardiovascular morbidity and wet age-related macular degeneration.

Secondary outcomes of lens and cataract surgery: More than just "best-corrected visual acuity".

Most studies evaluating cataract surgery focus on the primary outcome of early, central, best-corrected visual acuity. However, cataract surgery and intraocular lens (IOL) design have other secondary visual outcomes as well as impacts on various ocular tissues, the visual function, and quality of life. Some of these aspects are more difficult to quantify, or are historically neglected, but might be extremely important to patients.
