Easyton IOP Tonometer – Eye

EasyTon IOP Tonometer — Pen-Style Transpalpebral Applanation

Overview
Pen-style intraocular pressure (IOP) tonometer for fast, reproducible, stress-free screening and monitoring. Transpalpebral, cornea-sparing measurement via vibrational micro-applanation delivers Goldmann-comparable results without anesthetic, fluorescein, or corneal contact. FDA 510(k) cleared (K190382) for professional use in glaucoma care and broader ocular diagnostics.

Supportive/Benefit-Focused
No corneal touch → reduced contamination and irritation risk, no contact lens removal. Two-second acquisition with automatic averaging in mmHg. Suited to pediatrics, post-operative cases (including KPro), and field care. Galvanic measuring tip improves durability and long-term precision. Minimal training; consistent results at the point of care.

How It Works

1. Position rod gently on closed upper eyelid.

2. Activate measurement; device generates ~100 micro-vibrations per reading to minimize corneal thickness and biomechanical bias.

3. Average IOP displayed in mmHg on LCD.

What’s Included
• EasyTon IOP Tonometer (pen device)
• User manual

Indications for Use
• Glaucoma diagnosis and monitoring; ocular hypertension/hypotension
• Post-LASIK/refractive surgery assessment
• KPro and artificial cornea follow-up
• Retina, tumor, and trauma cases where corneal contact is undesirable
• Pediatric ophthalmology
• Off-road/field ophthalmology and routine IOP tonometry

Contraindications
• Upper eyelid deformity, scars, inflammation, or other pathology preventing proper placement
• Conjunctival/scleral disorders that vibration may aggravate
• Inability to sit upright during measurement (e.g., early post-op, severe spine/bone disease)
• Post-stroke or neurological conditions interfering with cooperation
• Eyes with altered biomechanical properties from recent surgery or procedures as specified by the manufacturer
