Proliferative Diabetic Retinopathy

Introducing a faster and risk-reduced treatment

Navilas delivers an advanced peripheral treatment by optimizing speed and comfort while maintaining medical efficacy. Navilas offers rapid pattern delivery at all available pulse lengths while significantly reducing patient discomfort. 

The computer assisted treatment concept enables selective and personalized retina therapies.


Faster through computer assistance

Navilas with 30ms pulses was the fastest pattern laser system in the comparison made by Jay Chhablani and Igor Kozak (2).

Utilizing computer assisted treatment concepts, Navilas is capable of delivering ETDRS-type 100ms pulses in a regular pattern.

Less pain

Less Pain with Navilas

Patients treated with Navilas reported a significant reduction in pain. Navilas maximizes patient comfort and compliance by using invisible infrared illumination and fast, steady pattern application (2).

More versatility

Targeted peripheral treatment enabled

Navilas is allowing for targeted peripheral treatments to optimally address the pathology based on diagnostic results such as far peripheral angiographies (4).

Uniform spots for optimal power setting

Owing to the unique combination of imaging capabilities and laser delivery, Navilas is allowing placement of large patterns in the far periphery without the risk of elliptic burns with uneven energy distribution.

Maintaining ETDRS parameters

As demonstrated by Palanker et al. fast pattern laser application requires an increased number of spots to be applied to achieve the same effect (5). Navilas uniquely addresses this need with automatic pattern pre-positioning and easy to use touch-screen positioning.

As an alternative, the navigated application of patterns with longer pulse durations enables adherence to ETDRS guidelines while ensuring a rapid treatment.
