This paper seeks to outline the history, market situation, clinical management and product
performance related to the correction of presbyopia with both contact lenses and spectacles …

Purpose Astigmatism blurs the retinal image of a circular spot along a particular orientation
rendering it an elliptical shape. Astigmatic patients demonstrate adaptation to residual …

Purpose To describe the association of refraction development and axial length (AL) in
young children and provide new insights into the progression of cylinder power. Methods …

Purpose: To evaluate the efficacy of paired opposite clear corneal incisions (OCCIs) in
Implantable Collamer Lens (ICL; STAAR Surgical) implantation surgery for correcting …

A retrospective cohort study was conducted to observe the correction effect of Toric
intraocular lens (IOL) implantation in cataract eyes with specific types of irregular corneal …

Purpose To investigate changes in astigmatism with age. Are changes from with‐the‐rule
(WTR) in younger ages to against‐the‐rule (ATR) in older patients mediated through oblique …

Background To investigate the prevalence and risk factors for astigmatism in 7-19-year-old
students in Xinjiang, China. Methods A school-based, cross-sectional study was conducted …

Background Existing research on the relationship between body mass index (BMI) and
astigmatism yields inconsistent results. This study analyses this association in a nationally …

This study explores whether children's refractive errors and visual behaviors reverted to pre-
COVID-19 levels a year after normal schooling resumed in Hong Kong as well as the impact …

A new, to the best of our knowledge, optical element designed to compensate regular
astigmatism while exhibiting increased tolerance to rotational misalignment is introduced …
