Eligibility Criteria
Inclusion Criteria
- Scheduled to undergo routine imaging for cataract surgery, refractive lens exchange or laser refractive surgery
Exclusion Criteria
- A cardiac pacemaker, implanted or wearable defibrillator, or other implanted metallic or electronic device (e.g. cochlear implant) in the head or neck
- Chronic or frequent nosebleeds, a bleeding disorder (e.g. hemophilia), or another condition that can lead to increased bleeding
- A known hypersensitivity (allergy) to the hydrogel material that comes into contact with the inside of the nose during use of the TrueTearTM device
- Pregnancy
- Presence of any ocular disease or condition which in the investigator's opinion would confound the study results
