Summary: Increased higher-order aberrations and improved accommodative accuracy were observed during orthokeratology treatment, but began to regress after the cessation of orthokeratology. A significant positive correlation between improved accommodative accuracy and slowed axial elongation was only observed during the first 6 months of treatment.

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: 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 aimed to compare the effects of orthokeratology (ortho-k) lenses with different back optic zone diameters (BOZD) on ocular aberrations and axial elongation (AE) in children over a two-year period. The results showed that after two years, the group wearing 5-mm lenses exhibited a smaller treatment zone diameter and less AE compared to the 6-mm group. The 5-mm group also showed a greater increase in higher-order aberrations (HOAs) and spherical aberration (SA) throughout the study. Additionally, the treatment zone diameter was significantly associated with changes in HOAs, SA, and coma.

Summary: The study found that the lenslet structure minimally impaired short-term visual performance on myopia control spectacle lenses, with concentric rings of aspherical lenslets having a significantly lower impact on both visual acuity and contrast sensitivity compared to honeycomb configuration with spherical lenslets.

Summary: The purpose of this study was to evaluate the impact of myopia control spectacle lenses with peripheral lenslets on central and peripheral visual acuity (VA). High-contrast and low-luminance conditions were tested using two lens designs: a highly aspherical lenslet (HAL) and a standard single-vision lens (SVL). The results showed that the HAL lens reduced central VA with peripheral gaze, but did not affect peripheral VA.

Summary: The study found errors in the focusing response of the human eye, with lags and leads observed in different stimuli distances. Objective and subjective measures were used to determine the optimal focus of the eye, with subjective measures showing smaller errors and visual acuity being maximized at or near the distance of the accommodative stimulus.

Summary: This study retrospectively investigated the axial length changes in myopic children wearing orthokeratology lenses and found that after initial shortening, the axial length rapidly rebounded during the washout period and shortened again when lenses were re-worn. The changes in axial length were significantly correlated with the initial axial length. Therefore, measuring axial length after the washout period can provide a more objective and accurate evaluation of orthokeratology, and the existence and degree of axial shortening can predict long-term myopia development.

Summary: Fixating through the periphery of novel lens designs slightly reduces low contrast visual acuity and reading speed, but does not affect high contrast visual acuity. However, the peripheral measures of vision are not significantly affected by the novel lens designs.

Summary: This study compared peripheral defocus, higher-order aberrations, and contrast visual acuity in myopic children wearing orthokeratology lenses and multifocal soft contact lenses with highly addition. The results showed that the MSCL group had larger peripheral defocus, less increase in higher-order aberrations, and worse contrast visual acuity compared to the OK lens group.

Summary: This study investigated the effects of an orthokeratology lens on tear film and tarsal glands, as well as myopia control in children with unilateral myopia, using an intelligent analysis model. The study found that tear film break-up times differed significantly in the treatment group, and there were also significant differences in the deformation coefficients of the meibomian glands. In contrast, the control group showed no significant differences.

Summary: Center-distance multifocal contact lenses (MFCLs) are believed to slow myopia progression by providing clear foveal vision and myopic defocus. Characterising the power profile of lenses is crucial in understanding their impact on retinal defocus. The study found variations in power profiles among different MFCL designs, indicating potential influences on myopia progression.

Summary: This study investigates the perception and adoption of myopia control strategies among African eye care practitioners. The results indicate that African eye care practitioners continue to predominantly prescribe single vision spectacles instead of other myopia control modalities, and their perception of the efficacy of these modalities does not align with the current best evidence. Clear practice guidelines and continuing education are needed to improve the management of myopic patients in Africa.

Summary: The study found a high prevalence of computer vision syndrome (CVS) and poor sleep quality among university students in Ghana, which were closely related to digital device usage behavior. There was a positive correlation between the duration of digital device use and the occurrence of CVS, and a significant association between the duration of digital device use and sleep quality.
