The majority of problems associated with soft lens wear in general are related to lens deterioration, deposits, care systems, and lack of patient compliance. The greatest problem with soft lenses is that they can never be totally cleaned. The point of a disposable lens wear program is to discard the lens while it is still in relatively good condition. If either the patient or the practitioner wishes to use the lens until problems occur, the entire system is rendered useless. Practitioners must emphasize to new patients that soft lenses become dirty and deteriorate regardless of the level of care; this deterioration will affect comfort and visual acuity; and frequent replacement avoids these negative factors.
