Abstract:

Objective   To investigate and evaluate the effects of composite prism on myopia progression in teenagers. Methods   One hundred and tuenty-six patients with myopia were randomly divided into two groups: treatment group (126 eyes) and control group(126 eyes). The treatment group weared composite prism and control group weared ordinary resin lenses. The two groups had no significant differences in age and refraction. They were followed up for 3 years, and refractive status, AC/A ratio,corneal curvature, and axial growth were evaluated and statistically analyzed.  Results   The myopic diopter deepened by (-0.43±0.24)DS in treatment group and (-0.91±0.56)DS in control group every year, and the difference was significant (P<0.01); the changes of the treatment group in axial length and corneal curvature had no statistical significance; more than 90% of the teenagers in treatment group felt very comfortable and no overt strabismus appeared. Conclusion   Composite prism can be used to control or slow the development of myopia effectively, and it is safe, comfortable, and acceptable for teenagers.
