Examining the effect and safety of orthokeratology in controlling the development of myopia: Based on fluorosilicone acrylic breathable material

Abstract

We aimed to evaluate the clinical effect and safety of orthokeratology in controlling the development of myopia. We assessed the changes in visual acuity, diopter change, axial length, corneal endothelium count, intraocular pressure, and corneal Q value in 30 adolescents with 60 years of wearing an orthokeratology lens. In this study, no significant difference was observed between the naked eye vision and corrected visual acuity before wearing the lens (t = –0.23, P = 0.59); furthermore, no significant difference was observed in diopter, axial length, corneal endothelium count, and intraocular pressure 1 year before and after wearing the lens (t = 1.24, P = 0.45; t = –0.89, P = 0.25; t = –0.43, P = 0.57; t = 1.43, P = 0.61); by contrast, there was a significant difference in the corneal Q value before and after wearing the lens (t = –8.37, P = 0.001). These results suggest that the fluorosilicone acrylic breathable material corneal orthopedic lens is safe and effective in controlling myopia, and has little effect on the physiology of the eye.

Optimization of Color Enhancement Processing for Plane Images Based on Computer Vision

“…A major way for humans to obtain information is through vision [1]. According to relevant statistics, in the process of obtaining information, most of the information is realized by the naked eye [2]. The information carrier seen by the human eye is mainly based on images.…”
