Aberration Analysis on the Central Deviation of Corrective Lens on Hyperopic Amblyopia
The +6.00 m-1 hypermetropia models and correction models were built by changing axial length and corneal curvature of the anterior surface using optical design program Zemax. Based on the correction models, the aberrations which were due to the central deviation of corrective lens were analyzed. For the +6.00 m-1 axial hypermetropia, when the lens offset is more than 4mm, the spherical aberration, astigmatism and distortion are beginning to affect vision. Because of the central deviation of corrective lens, the spherical aberration is obvious in the model which is high percentage of axis changing, while the distortion and astigmatism are no significant difference in various models. These aberrations will reduce the treatment of amblyopia. During the correction of the hyperopic amblyopia, it is necessary to measure the anterior surface radius of cornea and the eye axial length. According to the composition proportion of the refractive error, aspheric lens is designed individually for the hyperopic amblyopia in order to ensure the treatment of amblyopia.
