About
The present research focused on the effect of the age for the corneal biomechanics of low and moderate myopia patients after wearing orthokeratology (OK lens). According to age, the included cases were divided into 3 groups. Through the analysis of corneal biomechanical parameters, further learn the influence of OK lens on the patient cornea. It would help ophthalmologist and optometrist find out the potential issue and reach a better control result.
Full description
The present research focused on the effect of the age for the corneal biomechanics of low and moderate myopia patients after wearing orthokeratology (OK lens). According to age, the included cases were divided into 3 groups: Ⅰ (8-12 years old), Ⅱ (13-16 years old), Ⅲ (over 16 years old). The OK lenses used in the present study are of the same design (Euclid Systems Orthokeratology; Euclid System, Herndon, VA, USA). The base line (Day 0) and different follow-up time point (Day 1, Week 1, Week 2, Month 1, Month 3, and Month 6) of dynamic corneal response (DCR) (including 19 items) of the patients derived by Corvis ST were collected. The difference between before and after wearing OK Lens and the changes of parameters among the three groups were both analyzed. And the correlation between axis length (AL) and the 19 parameters also was analyzed. Through the analysis of corneal biomechanical parameters, further learn the influence of OK lens on the patient cornea. It would help ophthalmologist and optometrist find out the potential issue and reach a better control result.
