Title: Clinical study of orthokeratology lens for correction effects of adolescent myopia
Abstract: Objective
To investigate the correction effect and influence of orthokeratology lens and aspheric spectacles on adolescent myopia.
Methods
A total of 124 cases of juvenile myopia in our hospital from January 2012 to January 2013 was divided into experimental and control groups according to the principle of random. Patients in both groups were followed for a period of 2 years, patient's vision, binocular refraction, and eye axis length were recorded.
Results
Unaided visual acuity of patients in the experimental group was increased significantly, the trend was clear with statistical significance (P 0.05). In the experiment group, for patients wearing glasses, their axis lengths were (24.7±0.19)mm after six months. After 1 year, their axis lengths were (24.5±0.16)mm, and after 2 years, their axis lengths were (24.3±0.20)mm. Compared to non-wearing glasses before, which was (24.3±0.21)mm, the difference was not statistically significant (P>0.05). In the control group, for patients wearing glasses, their axis lengths were (24.8±0.20)mm after six months. After 1 year, their axis lengths were (24.9±0.17)mm, and after 2 years, their axis lengths were (25.7±0.15)mm. Compared to non-wearing glasses before, which was (24.5±0.18)mm, the difference was statistically significant (P<0.05).
Conclusions
Orthokeratology lenses can reduce myopia in adolescent patients, reduce the degree of anisometropia, and prevent the increase of the axial length. It can achieve the purpose of myopia control.
