In order to see the world in focus, rays of light that enter the eye must bend correctly and focus on the back of the eye.
It is this process, known as refraction that is affected in presbyopic patients and is triggered by the natural aging of the lens and the muscles that control it.
Presbyopia is a progressive condition that results in the loss of near vision from the age of 40 onwards, and can impact on a person’s lifestyle quite significantly.
You probably won’t realise how much you rely on near vision until it is affected, but the truth is that we need it for everyday, run-of-the-mill tasks such as reading. This extends to reading the newspaper, your current book, text messages, emails and even telling the time on your wristwatch.
A whole host of surgical techniques have been used to correct presbyopia in the past ranging from highly invasive procedures like scleral expansion surgery and clear lens extraction to less invasive methods such as corneal laser surgery and conductive keratoplasty.
However, the main problem with the above options was that many presbyopic patients were considered too old for corneal surgery that ran the risk of permanent changes in corneal structure, and too young for lens extraction.
This stuck between a rock and a hard place conundrum ultimately led to the development of refractive corneal inlays, like Presbia.
Implanted into your non-dominant eye, Presbia is a microlens that alters its refractive index and creates two focal points – one for far vision and one for near vision.
Taking less than ten minutes, inserting the Presbia microlens requires minimal downtime and the use of topical anaesthetic eye drops means you won’t feel a thing.
Besides eliminating the need for reading glasses and being completely invisible to the naked eye, Presbia offers a range of other advantages:
