Treatment
A. Optical treatment. Basic principle of treatment is to prescribe convex (plus) lenses, so that the light rays are brought to focus on the retina (Fig. 1). Fundamental rules for prescribing glasses in hypermetropia include:
1. Total amount of hypermetropia should always be discovered by performing refraction under
complete cycloplegia.
2. The spherical correction given should be comfortably acceptable to the
patient. However,
the astigmatism should be fully corrected.
3. Gradually increase the spherical correction at 6 months interval till the patient accepts manifest hypermetropia.
4. In the presence of accommodative convergent squint, full correction should be given at the first sitting.
5. If there is associated amblyopia, full correction with occlusion therapy should be started.
Modes of prescription of convex lenses
1. Spectacles are most comfortable, safe and easy method of correcting hypermetropia.
2. Contact lenses are indicated in unilateral hypermetropia (anisometropia). For cosmetic
reasons, contact lenses should be prescribed once the prescription has stabilised, otherwise,
they may have to be changed many a times.
