The lenses are usually rubbed between the palm of one hand and a finger, using an appropriate cleaning solution, then rinsed with a sterile saline solution. After cleaning, contact lenses need to be disinfected to kill any bacteria or other microorganisms which may still adhere to the lenses. If lenses are not disinfected, the microorganisms can reproduce, and when the lens is worn again the microorganisms will be introduced into the eye. There are a variety of disinfection systems available for different types of contact lenses. It is important to use the system recommended by the professional who prescribed the lenses, and to seek their advice before changing systems, as some of the systems are not compatible.
Consultations Prescribing contact lenses is a complicated process.
Contact lenses must not only correct refractive errors, but must also fit without causing any injury to the surface of the eye. They must move on the surface of the eye and allow the lids to ride over them with each blink, without being uncomfortable. They must also not provoke any reaction from the eye or the immune system. Professional care and advice is essential. There are many steps involved in arriving at a prescription for contact lenses.
