Intraocular Pressure Data Collection With Tonometers

Intraocular Pressure Data Collection With Tonometers

The goal of this clinical trial is to collect a comprehensive dataset of intraocular pressure values for developing a measurement algorithm for the new hand-held rebound tonometer device. The measurement algorithm shall fulfill the requirements of ANSI Z80.10:2014 standard. The study population is adults (age ≥ 18 years).

The intraocular pressure of the participants will be measured with four different tonometers.

Inclusion Criteria:

• Age ≥ 18 years

Exclusion Criteria:

• Subjects with only one functional eye

• High corneal astigmatism >3D in the study eye(s)
• Central corneal scarring
• History of prior incisional glaucoma surgery or corneal surgery, including corneal refractive laser surgery in the study eye(s)
• Microphthalmos
• Buphthalmos
• Contact lens use within one week of continuous wear and within one hour if lens is worn occasionally
• Dry eyes (clinically significant)
• Lid squeezers - blepharospasm
• Nystagmus
• Keratoconus
• Any other corneal or conjunctival pathology or infection relevant to this study
• Cataract Extraction within last 2 months in the study eye(s)
