Contact lens wear and the oxygen issue: A review

FO Owuagwu

Abstract


A review on contact lenses (CLs) and the importance of oxygen permeability (DK) and transmissibility (DK/L) in contact lens (CL) wear was undertaken. Motivation is a primary factor in determining a good candidate for CLs. Ocular consideration; systemic consideration and non-compliance of patients limit a patient's suitability for CL wear. The majority of complications encountered with CL wear are manageable by discontinuing their use. More severe, vision-threatening complications are rare. Hypoxia
contributes most tothe complications ofCLwear. Minimization of extended or over night-wear along with attention to compliance inlenscare reduces the risk of complications associated with CL wear.
