The Eye in Contact Lens Wear

Contact lens induced keratitis associated with contact lens wear.

PURPOSE To evaluate clinical characteristics, risk factors, management and outcome of contact lens induced keratitis (CLIK) associated with contact lens wear. METHODS The study comprised all consecutive patients presenting with contact lens related presumed microbial keratitis during a 12-month period at our department. Detailed demographic data, type of contact lens, duration of lens wear, w...

Scleral contact lens wear in unilateral aphakia.

Tear calcium levels and contact lens wear.

Hydrophilic contact lens spoliation can be associated with the deposition of calcium salts. The relationship between the concentration of calcium in tear fluid and contact lens use has been studied in healthy volunteers and in patients using various forms of hard and soft contact lenses, tear samples being collected with Schirmer strips and with lenses in situ. Methods are suggested for correct...

Extended wear contact lens related bacterial keratitis.

AIMS To report the clinical findings and visual outcome of patients with extended wear contact lens (EWCL) related bacterial keratitis. METHODS 11 cases with EWCL related bacterial keratitis were included. Corneal scrapings were obtained for cytology and cultures. RESULTS Nine patients had unilateral bacterial keratitis and two patients showed bilateral involvement. Corneal scrapings reveal...

Corneal response to rigid contact lens wear.

Three adult rhesus monkeys were subjected to 2 and 24 hours of polymethylmethacrylate (PMMA) contact lens wear. The induced corneal changes were examined with the electron microscope. Mild epithelial oedema as well as early degenerative cell changes was present already after 2 hours' wear. Rigid lens wear for 24 hours produced more severe oedema and cell alterations together with premature cell...
