Introduction: This study aimed to assess the safety and efficacy of a novel extended-depth-of-focus (EDOF) soft contact lens for myopia control in children.

Methods: A prospective, multicenter, randomized, double-masked, placebo-controlled, contralateral-eye comparison clinical trial was conducted in 72 children (40 male and 32 female) aged 9 to 14 years, with each eye randomly selected to wear either an experimental EDOF contact lens or a single-vision control lens at least 8 h per day, 5 days a week, for 52 weeks. Each contact lens was worn and then replaced daily.

We aim to assess the feasibility of topography-guided laser in situ keratomileusis (TOPOLINK) for correcting pre-existing and surgical-induced astigmatism. A retrospective, single center cohort study was conducted. Patients with pre-existing irregular myopic astigmatism were recruited into the primary group and those with irregular myopic astigmatism following laser in situ keratomileusis (LASIK) were recruited into the enhancement group.

Because of the high prevalence of myopia in Taiwan, understanding the risk factors for its development and progression is important to public health. This study investigated the risk factors for myopia and their influence on the progression of myopia in schoolchildren in Taiwan. Patients' clinical records were obtained retrospectively from ophthalmologists.

We report a patient with soft contact lens-induced keratopathy that caused Orbscan corneal topography (Bausch & Lomb) to show features suggestive of keratoconus. In cases such as this, Orbscan should be used with other examination techniques such as Placido disk-based topography or ultrasonic pachymetry to ensure the correct diagnosis.
