5. Unique Diaton Tonometer Diaton tonometry is a unique approach to measuring intraocular pressure (IOP) through the Eyelid & Sclera. Non-Contact (no contact with cornea), no anesthesia or sterilization required, pen like, hand-held, portable tonometer. Currently, there are several other methods to measure intraocular pressure - though all are corneal. Variations in corneal properties is the disadvantage to ALL of these methods. Our product, Diaton Tonometer, differentiates itself from all other devices. With the Diaton, IOP is measured through the palpebra (the eyelid) and the sclera. Because of this technique, any influence from the corneal parameters is prevented. A New Wave in Eye Care... 4

6. Awards & New Technology Recognition This new transpalpebral methodology has received many prestigious awards and Diplomas. Gold Medal of the International Exhibition of Innovation Research and New Technology "Brussels Eureca" and Gold Medal of the International Exhibition of Research and new Technology in "Geneva“, plus many others. 5

7. Typical Uses & Application Typical uses of the tonometer include the following : - Measuring IOP in preventive mass glaucoma screening - Measuring IOP without removing contact or scleral lenses - Measuring IOP in immobilized patients - measurement can be done sitting or supine - Measuring IOP in children. Measurement is taken outside of the visual field resulting in an improved patient experience - Patients with the following conditions: chronic conjunctivitis, corneal pathology including keratitis, keratotone, corneal dimness, after penetrating keratoplastics, Kpro keratoprosthesis, laser refractive correction, high degree of ametropy, astigmatism - Measuring IOP immediately post LASIK, LASEK, and PRK surgeries - Measuring IOP in patients with allergies to ophthalmic anesthetics or latex - IOP control during clinical observation and selection of adequate hypotensive therapy for glaucoma patients - Serial tonometry for obtaining Diurnal curve - Intended for use by Ophthalmologists and Optometrists as well as Inpatient & Outpatient Clinics such as Hospitals, Emergency Rooms, Nursing & Elderly Homes, General & Specialty Practitioners and Quick / Urgent Care Clinics. 6

12. Latest Clinical Findings (cont) Does IOP Increase During Scleral Lens Wear? Results: The Diaton measures IOP through the upper eyelid to the scleral surface. This allows clinicians to monitor IOP while scleral lenses are being worn. The correlation between IOP measurements taken with the Diaton and Goldmann were significant. Discussion: We observed that immediately following scleral lens application, the IOP increased in all of the test subjects. The initial IOP increase averaged 5.5 mmHg. The pressure appears to remain elevated throughout the wearing time (average 7.0 mmHg increase from baseline prior to removal), then immediately returns to baseline following scleral lens removal. This suggests that the suction force beneath the lens is a primary contributor to the IOP changes. IOP should be Measured and Monitored with Lens ON the eye. 11
