MK occurs as a result of infection of the cornea by replicating microbes (bacterial, viral, fungal or amoebae) and is usually preceded by hypoxia and/or an epithelial break. Contact lens wearers (particularly EW) are more prone to develop MK. Symptoms … Continue reading
Small (15-50µm), irregular shaped inclusions usually found in the paracentral to mid-peripheral zones of the cornea. Observation is best with retro-illumination. Microcysts show reversed illumination due to a suspected higher refractive index than the surrounding tissue. A hypoxic mechanism has … Continue reading
Multifocal lenses are designed for patients with low to moderate presbyopia. Each pair of lenses contain one eyes optimized for near viewing, and the other optimized for distance viewing. Typically, the dominant eye will be wearing the distance-optimized lens, and … Continue reading
Multipurpose solutions incorporate several components including disinfectants, surfactants, chelating agents and various buffering agents which will rinse, disinfect, clean and store the contact lenses.
