Subjects fit with VST or CRT type lens are reviewed 1 day to 2 year after first wearing the lens. Ocular examinations were performed, including slit-lamp biomicroscope, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), corneal topography (Medmont E300W, Medmont Pty Ltd, Melbourne, Australia), corneal refractive power (autorefractometer, KR880, Topcon, JAPAN), corneal epithelial thickness (Optical Coherence Tomography, RTVue-XR), axial length using IOL-Master 700 (Carl Zeiss Meditec AG). To investigate corneal and retina changes caused by overnight OK lens.
