Long-term observation of corneal complications and effectiveness by orthokeratology for myopia

Abstract

AIM:To observe the long-term effectiveness and corneal complications by orthokeratology in myopia patients. METHODS:A retrospective analysis was conducted for 324 patients(620 eyes)with myopia who weared orthokeratology lens with standardized examination and strict recheck. The change of uncorrected visual acuity, myopic diopter, corneal curvature, visual quality and the complications after continuous wearing orthokeratology for 6mo, 1 and 2a were observed.RESULTS:The uncorrected visual acuity was 0.15±0.14 before orthokeratology, 0.95±0.07 at 6mo after wearing, 0.93±0.10 after 1a, 0.90±0.10 after 2a, which was increased significantly in every group compared with that before wearing(PPPCONCLUSION:Long-term orthokeratology wearing can efficiently improve the uncorrected visual acuity, decrease the myopic diopter and corneal curvature. The standardized examination and strict recheck can ensure the safety of orthokeratology.
