- What About Disposable Contact Lenses?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: I have been wearing contact lenses for many years now, but
- periodically check back with my eye doctor to see how I am doing. Though I
- have had no problems in caring for my present lenses, my doctor suggested I
- consider getting the new "disposable" lenses. I don't like to fix something
- that isn't broken, but am considering this new purchase. What can you tell me
- about these lenses and do they have any advantages?
-
- ------------------------------------------------------------------------------
-
- ANSWER: Disposable contact lenses are the latest development available to
- many of the more than 19.5 million Americans who wear this type of vision
- correction. While daily wear lenses were made from a hard plastic material
- and had to be removed after about 10 to 14 hours, extended wear lenses of
- softer materials allowed patients to keep them in place for as long as four
- weeks. Though this was most convenient, it also led to a new problem.
- Deposits of protein, lipids and calcium coated these lenses, making them
- uncomfortable, and provoking giant papillary conjunctivitis, thought to be a
- chronic allergic response to the deposits.
- Proper cleaning of these extended lenses is difficult, requiring time, a
- number of sterile solutions, and proper techniques. It is an expensive and
- time consuming process, and often not fully understood or performed regularly
- enough by the contact lens wearers. In some cases patients developed allergic
- or toxic reactions to the preservatives used in some solutions. Then came the
- development of these new lenses, recently approved for use by the Food and
- Drug Administration.
- These lenses are worn for one to two weeks, after which they are thrown
- away, and another fresh set is used. There is no time for any substantial
- buildup of deposits, and no need spend either the time or money required to
- clean the extended wear lenses, a clear advantage. However the cost of lenses
- and office visits may exceed $500 a year, enough to tempt many people to keep
- the disposable lenses in place for longer periods than are safe. Not all
- visual problems can be corrected by these new lenses, but they can afford a
- care free correction for those who will play by the rules.
