Summary: The study evaluated the myopia control efficacy and long-term safety of the Breath-O-Correct orthokeratology (OK) lens using a 2-year randomized, single-blind clinical trial. The results showed that the OK lens significantly reduced axial length elongation in schoolchildren without adverse clinical effects or subclinical inflammatory responses.

Summary: The study investigates the ocular biological characteristics of myopic children with axial length (AL) reduction during Ortho-K treatment and provides clinical clues for better myopia control effects. After one year of Ortho-K treatment, children in the AL reduction group had decreased ACD, thickened CLT, thinned VCD, and smaller TZ compared to the AL elongation group.

Summary: This study compared the effectiveness of multifocal soft contact lenses (MFSCLs), orthokeratology contact lenses (Ortho-kCLs), and single vision spectacles (SVSs) for myopia control. The results showed that wearing MFSCLs and Ortho-kCLs significantly delayed myopia progression compared to SVSs.

Summary: Different BOZD OK lenses, DISC lenses, and SCL lenses have certain effects in retarding axial elongation in 8-11-year-old myopes. 5.0 mm-BOZD OK lenses and DISC lenses have better control efficacy for low myopic eyes compared to single-vision SCLs or 6.2 mm-BOZD OK lenses.

Summary: The prevalence of myopia is increasing in East and Southeast Asia, with strategies needed to reduce its progression. Encouraging outdoor activities and using low-dose atropine eye drops are beneficial measures for reducing myopia development. Individual risk-to-benefit ratios need to be considered for different treatment options based on age, health, and lifestyle.

Summary: This study compared the efficacy and safety of corneal refractive therapy (CRT) lenses and vision shaping treatment (VST) lenses for myopia control in children. The results showed that compared with VST lenses, CRT lenses had a weaker effect on myopia control but were safer. Different types of VST lenses had similar efficacy and safety in controlling myopia progression.

Summary: This study used a multi-level model to analyze factors, including environmental factors, that affect the control of myopia using orthokeratology. The results showed that younger age, being female, having lower myopia at baseline, a steeper flattest keratometry meridian, and no more than 5 hours of near work per day were associated with better myopia control effect using orthokeratology over a 2-year treatment period.

Summary: Contact lens-related ocular surface complications are more common in teenagers and young adults. This study investigated the changes in tear proteome of young patients wearing glasses, orthokeratology lenses, and soft contact lenses. The results showed that tear proteomes were altered by orthokeratology and soft contact wear and age. These findings highlight the need for further research on the ocular surface responses to contact lens wear in teenagers and young adults separately.

Summary: The study aimed to investigate the effectiveness of orthokeratology (ortho-k) lenses for myopia control and the corneal changes with increased compression factor. The findings showed that ortho-k lenses with increased compression factor can effectively slow down the progression of myopia without compromising corneal health. Further research is needed to confirm the potential mechanism of an increased compression factor for improved myopia control effectiveness.

Summary: The purpose of this study was to investigate the relationship between patients' baseline biometric factors or lens parameters and the diameter of the treatment zone in young myopic children undergoing Corneal Refractive Therapy. Retrospective review of data from patients undergoing Corneal Refractive Therapy lens treatment within two years was conducted. Results showed that spherical refraction, flat keratometric reading, Reverse Zone Depth 2, Landing Zone Angle 1, and lens diameter were independent factors of treatment zone diameter. Logistic regression analysis accurately predicted the treatment zone size with a 71.5% accuracy.

Summary: The main motivation for parents to choose ortho-k for their children was the rapid progression of myopia, with most learning about ortho-k through word of mouth. The most common symptom during treatment was itchy or sore eyes, usually only initially. Children's willingness to participate is crucial for successful ortho-k treatment, even though their motivation may differ from that of their parents. Ortho-k is widely accepted as an option for myopia control in children.

Summary: This study demonstrated that physiological recanalisation of the lacrimal passage after dacryoendoscopic surgery significantly reduced the positivity rate of conjunctival sac culture and the number of detected microorganism strains. It also decreased the presence of potentially pathogenic and drug-resistant bacteria while increasing the proportion of indigenous bacteria, leading to a normalization of conjunctival flora.

Summary: The study quantified stereopsis and other visual functions in patients with unilateral branch retinal vein occlusion (BRVO), finding that changes in visual acuity and contrast sensitivity affect stereopsis in these patients. Additionally, initial visual acuity was identified as a prognostic factor for posttreatment stereopsis.

Summary: This study investigated the relationship between contrast sensitivity (CS) and vision-related quality of life (VR-QOL) in patients with central retinal vein occlusion following treatment with ranibizumab. The results showed that CS had a stronger association with VR-QOL than visual acuity. The improvement in CS was significantly correlated with the improvement in VR-QOL, while visual acuity improvement was not correlated. Additionally, the distance between the external limiting membrane and retinal pigment epithelium and average ganglion cell-inner plexiform layer thickness were associated with CS.

Summary: Extended depth of focus contact lenses significantly improve visual acuity at near to intermediate distances in eyes with monofocal intraocular lens implantation, but may cause a decrease in far visual acuity under low-contrast conditions and a slight decline in contrast sensitivity at middle to high spatial frequencies.

Summary: Two novel imaging methods were used in this study to detect significant amounts of deposits on heavily worn orthokeratology (OK) lenses, and were sensitive enough to detect a reduction in deposition following the use of the two cleaning solutions tested. Furthermore, these methods could visualize and quantify the thickness of lens deposits along the reverse curve.

Summary: This study aimed to investigate the effect of dry eye disease (DED) on the repeatability of ocular biometric measurements in cataract patients. The findings revealed that DED was associated with a decline in the measurement repeatability of corneal curvature radius and axial length. Shortened tear film break-up time and higher corneal staining scores were correlated with a deterioration in measurement repeatability.

Summary: The impact of visual functions on vision-related quality of life (VR-QoL) in patients with cystoid macular edema secondary to central retinal vein occlusion (CRVO-CME) is not well understood. This study examined various visual measures and found that visual acuity of the fellow eye had the strongest impact on VR-QoL, while contrast sensitivity and stereopsis were also associated with VR-QoL.
