Contact Lenses Care

Sometimes the people who need contact lenses most are those who may have the greatest difficulty in inserting and removing them. This seems a good place to deal with some of the problems such people have in inserting lenses, and how these may be relieved. In the first place, a patient who has had a cataract removed has a very long-sighted eye so that the nearer an object is brought, the more blurred it becomes. Read the rest of this entry »

Q. Are suckers useful for inserting lenses?

A. Generally, no. The finger-tip is much better, because it is soft and therefore less likely to cause accidental damage.

A bandage lens, also called a therapeutic lens, is a special soft, very thin, high-water-content contact lens. In 1974 this hydrophilic lens was the first type to be used on an extended-wear basis, but without incorporating a prescription. It has a wide variety of uses before ocular surgery, after ocular surgery, and sometimes instead of surgery. It can also be therapeutic in conditions that do not respond to any other form of treatment.

The lens functions basically as a protective shield and prevents a damaged or ailing cornea from coming into contact with the eyelids and the air. Healing is thereby accelerated and pain is alleviated for as long as the lens is worn, which is on an extended basis (more than twenty-four hours). Read the rest of this entry »

Conventional soft contact lenses cannot be used to correct moderate to large amounts of astigmatism. Their pliable nature causes them to conform to irregularities in the shape of the cornea and thus duplicate the astigmatic refractive error. Hard contact lenses are firm and hold their shape; they are able to correct high amounts of astigmatism because the spherical undersurface of the lenses and the tears beneath them create a new, smooth optical surface.
