We describe a radial keratotomy technique for the correction of high myopia. At present, the highest myopic correction is obtained by the smallest optical zone diameter (3 mm), by the maximum number of incisions (16), by the maximum number of redeepenings (3), and by incision of the tissue bridges. To obtain additional corneal flattening, we suggest lengthening the incisions curvilinearly. We present results of cases treated with curvilinear incision and two other techniques.

Single-cell RNA sequencing (scRNA-seq) offers remarkable insights into cellular development and differentiation by capturing the gene expression profiles of individual cells. The role of dimensionality reduction and visualization in the interpretation of scRNA-seq data has gained widely acceptance. However, current methods face several challenges, including incomplete structure-preserving strategies and high distortion in embeddings, which fail to effectively model complex cell trajectories with multiple branches.

Infertility is increasing globally, affecting one in six adults due to factors like delayed childbearing and lifestyle changes. Despite the recognition of the importance of increasing fertility awareness, levels remain low. This study evaluated the perceptions of 'FActs!', a serious game aimed at improving adolescents' fertility awareness.

Purpose: Astigmatism can lead to meridional amblyopia, an orientation-specific visual deficit. This study investigated the effects of astigmatism on meridional anisotropy in contrast sensitivity (CS) and steady-state visual evoked potential (ssVEP) across a range of spatial frequencies.
Methods: Thirty-two young adults with a best-corrected distance visual acuity of logMAR 0 or better were categorized into two groups: highly astigmatic (HAS, = 16) with spherical-equivalent error (SE) ≥ -6.

Background: Clinical education is an essential part of medical science education in the operating room, and considering its high importance, it is necessary to identify challenges in this regard. The study aims to explain the perception of students and professors regarding the challenges and strategies for improving education in the operating room. The context of this study was the Khomein School of Medical Sciences.

Precise segmentation of unmanned aerial vehicle (UAV)-captured images plays a vital role in tasks such as crop yield estimation and plant health assessment in banana plantations. By identifying and classifying planted areas, crop areas can be calculated, which is indispensable for accurate yield predictions. However, segmenting banana plantation scenes requires a substantial amount of annotated data, and manual labeling of these images is both timeconsuming and labor-intensive, limiting the development of large-scale datasets.
