Eye & contact lens
-
To examine the effects of soft contact lenses on tear breakup time (TBUT), basal Schirmer test result, and the conjunctival surface in patients wearing contact lenses. ⋯ We suggest that TBUT and Schirmer test result be carefully monitored in contact lens wearers. Impression cytology may be used as a safe, simple, and noninvasive method in the diagnosis of ocular surface alternations in patients with contact lens intolerance.

Case Reports
Pseudomonas keratitis associated with continuous wear silicone-hydrogel soft contact lens: a case report.
To report a case of Pseudomonas aeruginosa culture-positive microbial keratitis in a patient wearing continuous-wear silicone hydrogel soft contact lenses. ⋯ The recently introduced continuous-wear silicone hydrogel soft contact lenses, with their hyper oxygen permeability (Dk), have been shown to overcome hypoxia-associated complications and to have less P. aeruginosa binding to the corneal epithelium. Our case shows that sight-threatening microbial keratitis can still occur even with silicone hydrogel soft contact lenses. Contact lens practitioners should educate patients on the risk of sight-threatening microbial keratitis, the need for patient compliance, and prompt assessment of contact lens-related complaints.
