Corneal and conjunctival impression cytology in soft contact lens wearers.
This study assessed changes in corneal and conjunctional cytology in 25 soft contact lens (CL) wearers and compared them with matched controls. We found 80% of grade IV keratinization in CL users for more than 7 years. Keratinization was directly proportional to duration of CL use. Conjunctival cytological changes worsened with decreasing pH, whereas corneal keratinization showed no significant correlation.
