Contact lenses- what are they?

Contact lenses are small, very thin optical discs that are designed to rest on the cornea. They are held in place by a layer of tears present between the contact lens and cornea. They are used most frequently to correct errors of refraction like myopia (short sight), hypermetropia (long sight),astigmatism(cylinder power) & presbyopia.

No touch fitting

Topography Assisted Contact Lens Fitting:

The ‘ no-touch’ technique of contact lens fitting wherein computerized corneal topography is used to simulate the contact lens fit on the eye and helps in deciding the lens parameters. The contact lens can be ordered directly from these data without the patient undergoing any trial.
