Study on the effect of keratoplasty on the visual quality of myopia in adolescents

Abstract

AIM: To observe the adolescents with different degrees of myopia who wore orthokeratology lens for 1a were visited and discuss the influence and safety of orthokeratology for curing the adolescent myopia.METHODS: Totally 158 cases of adolescent myopia(-1.00D to -8.00D)who all wore the same brand orthokeratology lens were selected from September 2016 to December 2017. Their visual quality, including aberration detection, subjective discomfort and visual quality questionnaire was observed for 1a. RESULTS: After wearing orthokeratology, the patients' total RMS decreased, while the RMSh, the RMS3(including coma)and the RMS4(including spherical aberration)increased. The higher of baseline degree, the higher incidence of subjective visual discomfort, and the difference between pre-wearing and after was not statistically significant in subjective visual quality score(P>0.05).CONCLUSION: The patients' objective visual quality decreased after wearing orthokeratology lens. However, the long-term observation revealed that the overall visual quality had no significant impact on lifelihood and learning, which indicates orthokeratology is a safe and effective mean of myopia curing.
