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

Several refractive and therapeutic treatments as well as several ocular or systemic diseases
might induce changes in the mechanical resistance of the cornea. Furthermore, intraocular …

Purpose To analyze the change in subfoveal choroidal thickness (SFChT) and its
relationship with changes in axial length (AL) in myopic children treated with …

Purpose.: To investigate the short-term effect of orthokeratology (ortho-k) lens wear on the
anterior segment length for validating the use of axial length for monitoring myopic …

Purpose To determine the efficacy, predictability and safety of long-term orthokeratology in
children and adults. Methods Case histories of 300 orthokeratology patients (596 eyes; …

Purpose: To study the short-term corneal response to corneal refractive therapy for myopia
and correlate it with corneal biomechanical properties as measured with the ocular …

Purpose: To investigate the biomechanical changes in the cornea, in terms of corneal
hysteresis (CH) and corneal resistance factor (CRF), with short‐term orthokeratology (ortho …

Objective To determine changes in various ocular parameters of adults wearing
orthokeratology (ortho-k) lenses and their levels of satisfaction and quality of life (QoL) after …

Purpose: To investigate the stability of the treatment zone (TZ) size during Corneal
Refractive Therapy (CRT™) over 4 weeks of lens wear, and to determine the relationship …

Purpose: To evaluate the subjective satisfaction in visual stability, night vision complains,
and light distortion phenomena, and also the number of hours and days per week of lens …
