The influence of further consultation adherence on myopia progression after children wear glasses

Objective To explore the influence of further consultation adherence on the increase of degree of myopia after myopia children wear glasses. Methods A total of 170 cases of myopia children were collected (spectacle lens power: 340) who had received treatment in our hospital and worn glasses during June 2013 to June 2015; and were divided into three groups according to regular further consultation period, among which there were 53 children in the group with three-month regular further consultation period, 60 children in the group with six-month regular further consultation period, 57 children in the group with one-year regular further consultation period; finally analyzed the changes of refractive status for patients after wearing glasses in 6 months and one year. Results Since there was no significant statistic difference (F=0.194, P=0.842) in ages when the patients in three groups were original diagnosed, and there was also no statistic difference (P >0.05) in diopter of spherical power, astigmatism degree, and spherical equivalent degree, the data collected had clinical comparability. In addition, there was no clear statistic difference in the increase of spherical equivalent degree for patients, with 3-month further consultation period and 6-month further consultation period, visiting the doctor in the sixth month. As for the three groups, the spherical equivalent degree increased respectively -0.79±0.37, -0.81±0.36 and -0.92±0.40 one year later. There were statistic differences in the comparison among three groups (F=4.066, P=0.018); for the comparison between 3-month group and 6-month group, there was no statistic differences (P >0.05); however there were statistic differences (P=0.009, P=0.022) between one-year group and 3-month group, one-year group and 6-month group. When the astigmatic degree was compared with the degree initially diagnosed one year ago, there was no statistic difference (P >0.05) for all three groups. Conclusions Regular further consultation and timely replacement lenses may slow progress myopia of school-age children in a certain degree.
