title: Corneal and conjunctival impression cytology in soft contact lens wearers.
abstract: 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.
