Effects of combined training with CAMP vision simulating apparatus,convex lens and triple prism on AC/A in adolescent with myopia;

According to the laws of dispersion and complete reflection, the refractive indexes of water at different wavelengths are measured by use of a spectrometer and a set of triple prisms.

This paper presents the theoretical formula and experimental method for masuring refractiveindex of triple prism by any angle of deflection, and gives the comparison of the measuring results by minimum angle of deflection and both are almost the same in error.

Objective To evaluate the safety, efficacy, predictability and stability of Using an erodible disc coupled with an axicon lens for correction of hyperopia in laser in situ keratomeleusis (LASIK) Methods Correction was performed on 24 eyes of 15 patients with hyperopia with the rang of preoperative diopter of +1.
