Laser for outpatient bladder cancer management

Photo-coagulation of non-invasive bladder tumors


We wish to enable more widespread treatment of bladder cancer in simpler office- and outpatient-settings, by providing the medical professionals a safer, gentler, faster and more efficient tool for managing non-invasive bladder cancer. Optheras wish to enable early detection and treatment, to help improve the quality of life of patients with bladder cancer.


People first

The wellbeing of patients, employees and customers is core to us.


We thrive to innovate and be at the forefront of technology.


We are dedicated to bring forward new solutions for the benefit of mankind.

Bladder cancer

Bladder Cancer (BC) is a worldwide challenge, being the 10th most common cancer worldwide1. In both US and EU, BC is the 6th leading type of cancer*,** with an estimated economic burden of about €4.9 billion in EU in 2012**. Half of the diagnosed bladder cancer is non-invasive to the bladder wall.

The risk of recurrence is high, so frequent surveillance, recurrent surgery and hospitalization is often required. Transurethal Resection of Bladder Tumor (TURBT) is the golden standard for treatment. An invasive surgical procedure, performed in hospital under anesthesia. Therefore, BC has one of the highest lifetime cost pr. patient of all cancers. Furthermore, the need for repeat procedures can reduce patient’s quality of life.

Better management of BC requires improvements in detection, diagnosing and treatment, and it is important to improve the quality of life for BC patients, while supporting the health system in efficient use of medical ressources
