E300 Corneal Topographer

Setting topography standards

The topographer of choice

The Medmont E300 topographer is used extensively by top contact lens manufacture designers and consultants and the majority of optometry educational universities. It’s often used in clinical studies. The E300 has a reputation as the gold-standard for fitting specialty contact lenses. The others are measured against it.

Performance matters

The E300, with its small-cone placido disc design, allows for precise and actual captured data across the cornea. In contrast, large-cone placido disc systems are prone to data loss, which leads to guessing.

First-fit success

With the goal of first-fit success, the E300 optimises throughput and reduces rework with proven precision and repeatability. It focuses on precision to enable fast fit success.

Don't guess

Designed to take guessing out of the equation with limbus-to-limbus corneal coverage and real data. This enables a more accurate baseline map (great for complex cases) for less rework and chair time and more satisfied patients.

Easy to use

The intuitive Medmont Studio software is made to be easy to learn and operate by everyone on your team. Topography maps are captured automatically in seconds and quality scored to give you confidence. Difficult surfaces become simple and patient comfort is optimised.

Non-invasive excellence

A study by the University of Melbourne determined the E300’s Auto TBUT dry eye analysis is repeatable, more sensitive and specific than fluorescein, and provides the user with a non-invasive measure of tear-breakup in line with DEWSII report recommendations.

“Medmont E300 is an essential tool for the patient management in our Myopia Control Clinic, UC Berkeley Eye Center. I also co-manage many specialty lens patients with my colleagues in China hence had the experience working with more than a dozen different corneal topographers. Comparing to other topographers I have used, E300 allows the largest data sampling area and the best repeatability."
