ABSTRACT:
An applicator device and procedure is disclosed directed to the controlled placement of a minute amount of fluorescein onto the cornea of a patient's eye. The fluorescein is used as a staining agent to permit applanation tonometric measurements. The fluorescein is applied with a disinfectant to the tonometer lens using a special applicator. The disinfectant evaporates leaving a thin film residue on the lens, which is subsequently redissolved in the tear film above the cornea.
The foregoing procedure enhances the tonometer measurements while simplifying the process and reducing risk of infective contaminates from entering the eye region.
