Analysis on risk factors for dyed cornea of orthokeratology and interventions / 中国实用护理杂志

ABSTRACT

Objective To investigate the related risk factors for dyed cornea of orthokeratology, and to analyze the related risk factors, and to determine the independent risk factors, Provide evidence for intervention measures. Methods The clinical date were investigated for 990 patients with fitting orthokeratology lens between may.2014 and may.2016 in our hospital,through access to medical records, follow-up visit,questionnaire investigation to find out the cause of orthokeratology adverse reactions, the related risk factors were analyzed by univariate and multivariate Logistic regression analysis, using SPSS17.0 statistical processing. Results The incidence rate of dyed cornea of orthokeratology lens fitting in was 14.55%(144 in 990 patients); the single factor analysis found gender, age, region, refraction, lens position, family members, no significant difference . Eye disease combined (χ2= 28.73, P＜0.01), Schirmer I test (χ2=17.68, P＜0.01), lens activity (χ2=67.1, P＜0.01), Lens deposit(χ2=64.29, P＜0.01), lens wearing time (χ2=43.25, P＜0.01), health habits (χ2=38.01, P＜0.01) and water resources (χ2=3.81, P＜0.05), the difference was statistically significant; Logistic Logistic regression analysis found that Schirmer I test ( OR=4.126, P=0.003), lens activity ( OR=1.733, P=0.104), Lens deposit( OR=3.723, P=0.038), lens wearing time ( OR=5.034, P=0.002), health habits ( OR=6.544, P=0.002) and water resources ( OR=7.501, P=0.002) were independent risk factors for adverse reactions of orthokeratology. Conclusions Intervention measures that improve the fitting technology, complete removal of lens depositthe, Control wearing time, improve the health behaviors of the patients with the habit, use saline and professional cleaning are of great significance to reduce the incidence of adverse reactions of orthokeratology.
