Some people are reluctant to remove their
lenses every now and then. If that is also the case with you then why
not try your hands on the continuous wear lenses which give you the
freedom from removal for up to 30 days. But, some serious conditions
were visualized during their use like, infections and ulcers on the
cornea and so they were immediately called off from the market place and
were restricted for use.
Instead of these
lenses people have started using regular or extended wear lenses. But,
with the advancement of technology, the complications related to
continuous wear lenses earlier have been overcome and now these type of
lenses are safe to use. They only require normal lens care for their
proper hygiene. The two manufacturers who have taken the approval of FDA
for marketing continuous wear lenses in the United States are CIBAvision
and Baush and Lomb.
These new generation continuous wear lenses
are made from silicone hyrogel which helps in allowing more oxygen to
reach the cornea thus decreasing the possibilities of any complications
that had occurred in the past. It is still found that very few people
use these types of lens. Only 67 % of patients wear them for 22 to 30
days on an average. However, these lenses provide comfort and
convenience as it is good for people who are the strong candidates for
surgical procedures.
No matter how safe these lenses have become
but they still carry a slight risk of developing an eye disease or
infection. According to a study conducted by Cibavision, about 5 % of
697 patients developed inflammation and deposits in the eye after using
these lenses. So, along with the various benefits, they too bear some
disadvantages and risk factors.
