Redefining the Treatment of Intermediate AMD with 2RT®
2RT® is a proprietary, minimally invasive nano-pulse ophthalmic laser therapy, which offers the potential to intervene earlier in the management of age-related macular degeneration (AMD) and thereby eliminate or delay the risk of vision-threatening complications associated with the disease.

Until now, there’s been little advance in treating AMD before it progresses to the vision-threatening complications associated with the late stage of the disease, referred to as Wet AMD.
That’s why 2RT® represents such an important potential breakthrough.
Unique to Nova Eye Medical (ASX: EYE), 2RT® is a non-invasive, nano-pulse ophthalmic laser therapy that has been developed to slow the progression of AMD.
2RT® works by stimulating the rejuvenation of cells in the retina to initiate a healing response that targets the underlying causes of AMD.
An extensive multi-center clinical trial has shown that 2RT® achieves a four-fold reduction in the progression to late-stage AMD in 76% of selected intermediate AMD patients.*
With 2RT®, ophthalmologists have the potential to intervene sooner for the majority of intermediate AMD patients before a significant threat to their vision occurs.

Early Stage AMD
Based on current estimates, 85% of people with AMD have the disease in either the early or intermediate stage — and this is estimated to be 175 million people worldwide.
People with early or intermediate AMD are at risk of the disease progressing to the late-stage, advanced form of the disease, which is associated with irreversible vision loss.
What is Macular Degeneration, or AMD?
Age-related macular degeneration (AMD) is a chronic eye disease that can result in distorted vision and/or a loss of central vision.
AMD is the leading cause of blindness in industrialized countries and most frequently affects people over fifty years of age.
In its early stages, AMD is characterized by the presence of waste deposits under the macula — that’s the part of the eye at the center of the retina that processes sharp, clear straight-ahead vision.
The waste deposits, known as drusen, are frequently accompanied by pigmentary abnormalities such as light or dark spots in the macula.
While there have been major advances over the past decade in the treatment of AMD in its late stages, there has been little progress in the treatment of the disease in its early stages.
What’s more, there has been little breakthrough at the early stage of the disease to prevent it progressing to the vision-threatening complications associated with late-stage, advanced AMD.
AMD can be diagnosed with a simple eye examination. Detecting changes early through regular check-ups with an optometrist or ophthalmologist can identify the disease before sight-threatening complications occur.
How does AMD affect vision?
In its early stages, AMD can have little or no effect on vision. As AMD progresses, detailed, central vision is affected and becomes worse. In late, end-stage AMD all detailed central vision may be permanently lost, which can result in legal blindness.

What is 2RT?
2RT® is a proprietary nano-pulse ophthalmic laser therapy that, when applied early in the disease process, has shown the potential to slow the rate of progression of AMD.
A restorative treatment, 2RT® stimulates a process of cellular rejuvenation, initiating a wound-healing response in the eye.
2RT® features a unique nanosecond pulse of laser light. This ultra-short laser pulse stimulates a process of cellular rejuvenation to treat some of the degenerative processes that cause AMD.
Through pre-clinical work and studies, 2RT® has been shown to rejuvenate the retinal pigment epithelium, known as the RPE. The RPE is an important layer of cells responsible for supporting the health of the retina.
The ultimate goal of 2RT® is to prevent the progression of AMD to its late stages… if we can slow down the rate of (Bruch’s membrane) aging and restore function to what it was when the patient was in their teens, we should be able to significantly delay AMD onset.

About the LEAD Trial
The LEAD trial, which was published in the peer-reviewed journal Ophthalmology, was a randomized, 36-month, multi-center trial that highlighted the potential for 2RT® to significantly delay the degenerative processes associated with AMD in a significant proportion of patients with intermediate AMD.
77% reduction in the rate of progression to late-stage AMD in 76% of suitable patients who received 2RT® over the 36 months of the LEAD Trial.
