Effects of long-term contact lens wear on the cornea
Overview of the effects of long-term contact lens wear on the cornea / From Wikipedia, the free encyclopedia
Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Effects of long-term contact lens wear on the cornea?
Summarize this article for a 10 year old
Long-term contact lens use can lead to alterations in corneal thickness, stromal thickness, curvature, corneal sensitivity, cell density, and epithelial oxygen uptake, etc. Other changes may include the formation of epithelial vacuoles and microcysts (containing cellular debris) as well as the emergence of polymegethism in the corneal endothelium. Decreased corneal sensitivity, vision loss, and photophobia have also been observed in patients who have worn contact lenses for an extended period of time. Many contact lens-induced changes in corneal structure are reversible if contact lenses are removed for an extended period of time.
