Performance Evaluation of the OCUTOP Hand-held Corneal Topographer

Sponsor: University of Plymouth

Summary

The OCUTOP is a new hand-held camera that photographs the front of the eye to map the shape of the cornea and to assess the tear film. Before it can be used in eye care it must be compared with the instruments that clinics already use. In this study, adults attending one of two UK eye clinics for an ordinary appointment are invited to have both eyes measured once with the OCUTOP and with the clinic's usual instruments, in a random order, and to complete two short questionnaires. The visit adds about 30 minutes; nothing is put in the eye and no treatment is given. The study measures how closely the OCUTOP agrees with the reference instruments for corneal curvature, tear break-up time and tear meniscus height, how repeatable it is, how often it produces usable images, how acceptable participants and clinicians find it, and whether any adverse events occur.
