Clinical analysis of controlling myopia progression in children and adolescents with small light heart design plastic keratology lens
Objective To explore the clinical analysis of controlling myopia progression in children and adolescents with small light heart design plastic keratology mirror.Methods A total of 60 patients with low myopia aged 8-15 years old who were treated in the ophthal-mology outpatient department of Haining People's Hospital from December 2022 to June 2023 were selected and divided into design group 1(n=20),design group 2(n=20)and design group 3(n=20)according to different optical design of orthokeratology len-ses.Orthokeratology lenses with optical area diameter of 5.0 mm,5.5 mm and 6.0 mm were worn to compare axial length,diopter,pupil diameter,corneal tear film function and adverse reactions in each group.Results After 1 year of wear,the axial length of eye in design group 1,design group 2 and design group 3 were(23.19±0.93)mm,(23.50±0.23)mm and(23.99±0.25)mm,respectively.The axi-al length of eye in design group 1 was lower than that in design group 2 and design group 3(P＜0.05).The increase of diopter in design group 1 was slower than that in design group 2 and 3(P＜0.05).The cell area difference coefficient and tear film rupture time of design group 1 were lower than those of design group 2 and 3(P＜0.05).The incidence of adverse reactions in design group 1,design group 2 and design group 3 was 20.00％,20.00％and 25.00％,respectively,with no statistical significance(x2=0.196,P=0.996).Conclusion Compared with orthokeratology lens with optical area diameter of 5.5 mm and 6.0 mm,wearing orthokeratology lens with optical area di-ameter of 5.0 mm is more effective in controlling ocular axis growth in children and adolescents with low myopia,and does not increase ad-verse reactions.
