Effect and Safety for Youth Myopia Patients Fitted with Orth-Klents
Abstract: Aim: To observe the effect and safety of orthokeratology contact lenses for rectifying myopia and controlling the development of myopia. Methods: By studying retrospective case series, the myopia of 178 cases (356 eyes) was corrected by orthokeratology contact lenses and the changes of visual acuity, corneal curvature, the central corneal thickness, corneal endothelium and corneal conjunctival complications rate were all improved. The youth myopia patients were followed up at 1 month, 3 months and 6 months, 1 year, 2 years respectively and Ocular surface health was ex-amined by slit-lamp microscope. Results: Orthokeratology contact lenses can reduce myopia sig-nificantly and control degree development. A day later, there are about 54.87% the visual acuity ≥1.0; a month later, about 99.14% ≥1.0; 3 months later, about 100% ≥1.0. After 2 weeks without using orthokeratology, 56 eyes were decreased by 0.25D - 0.5D accounted for 17.95%, unchanged in 194 eyes accounted for 62.18%,60 eyes were increased 0.25D - 0.50D accounted for 19.23%, only two eyes were increased 0.75D. There were no remarkable complications in the ocular surface. There were no significant changes in corneal thickness, corneal endothelia and intraocular pressure after two years Ortho-K CL wear (P > 0.05). Central curvature flattening was observed. Conclusion: Orthokeratology regarded as a non-traumatic way to rectify myopia can reduce diopter and control the development of myopia effectively.
