Orthokeratology (ortho-k) is the process of deliberately resha** the anterior cornea by
utilising specialty contact lenses to temporarily and reversibly reduce refractive error after …

We compared the efficacy of controlling the annual increase in axial length (AL) in myopic
Caucasian children based on two parameters: the back optic zone diameter (BOZD) of the …

Purpose To present the 1‐year results of the Variation of Orthokeratology Lens Treatment
Zone (VOLTZ) Study, which aims to investigate the myopia control effect of orthokeratology …

Intervention to slow axial elongation and progressing degree of myopia has become an
important public health issue. Although orthokeratology (OrthoK) has been prescribed to …

Purpose To compare axial elongation, relative corneal refractive power (RCRP) distribution
within the pupillary diameter, and corneal higher-order aberrations (HOAs) in myopic …

Background To investigate whether the treatment zone size (TZS) and treatment zone
decentration (TZD) will affect the axial elongation in myopic children undergoing …

Background To confirm the association between treatment-zone (TZ) decentration and axial
length growth (ALG) in children who underwent orthokeratology; and to explore the …

Purpose To compare axial elongation (AE) and treatment zone (TZ) characteristics in
children wearing 6 mm or 5 mm back optic zone diameter (BOZD) orthokeratology (ortho‐k) …

Purpose To compare changes in ocular aberrations in children wearing orthokeratology
(ortho-k) lenses with a back optic zone diameter (BOZD) of 6 mm (6-MM group) or 5 mm (5 …

Background To investigate the control effect on the axial length elongation using corneal
refractive therapy (CRT) with different optical zone diameters (BOZDs). We also sought to …
