Therapeutic and Corrective Use of Contact Lens

The most common use of contact lens is corrective use, to correct the refractive errors of the eye. Contact lens is also sometimes used for therapeutic purpose.

Therapeutic use of contact lens:

Commonly soft contact lenses are used for therapeutic purpose and for treatment of non refractive errors of eye. Sometimes soft contact lenses are used to protect the injured eye or in corneal ulcer to allow the injury to heal properly. Soft contact lens is used for protecting cornea from constant rubbing of cornea due to blinking, which is known as bandage contact lens.

Other common uses of therapeutic contact lens are in dry eye, keratitis, corneal edema, bullous keratopathy, anterior corneal dystrophy, etc.

Corrective use of contact lens:

Corrective contact lenses are like glass (spectacles) that help to focus light correctly onto retina, so that we can see correctly without any error. Common refractive errors of the, such as myopia (short sightedness or person unable to see objects far away), presbyopia, hypermetropia (long sightedness or person unable to see objects which are near), astigmatism are best suited for use of contact lens. Corrective contact lens can improve vision, which may not be normal due to refractive errors of the eye.
