Long-term contact lens use can lead to alterations in corneal thickness, stromal thickness, curvature, corneal sensitivity, cell density, and epithelial oxygen uptake. . Other structural changes may include the formation of epithelial vacuoles and microcysts (containing cellular debris), corneal neovascularization, as well as the emergence of polymegethism in the corneal endoth

There is often a history of recent corneal injury, such as corneal abrasion or ulcer, but also may be idiopathic or due to corneal dystrophy or corneal disease. In other words, one may develop corneal erosions as a result of another disorder, such as epithelial basement membrane dystrophy ...
