Laser Blended Vision for Ageing Eyes (presbyopia)
First available in the UK at London Vision Clinic, PRESBYOND® Laser Blended Vision is an innovative treatment for ageing eyes which was pioneered by Professor Dan Reinstein.
Causing the need to use the dreaded reading glasses, presbyopia comes to most of us – regardless of our eyesight in our youth. Coming on slowly, it often moves from being a slight inconvenience to become a real hassle in day to day living as we struggle with small text, smartphones, and restaurant menus. Most of us can accommodate or compensate for the early symptoms, and after a while, we get used to carrying reading glasses or having to fork out for expensive varifocals.
What is presbyopia?
Presbyopia literally translates as ‘old eye’. Unfortunately, ageing affects the eye just as it affects every other part of the body. Starting in early middle age, the lens inside the eye begins to lose its ability to change shape ‘zoom’ from distance to near and back.
As we can’t avoid ageing, nobody is immune to developing presbyopia, and if left unchecked, inevitably leads to the need for reading glasses, bifocals, or varifocals. In this short video, expert laser eye surgeon Mr Glenn Carp explains what exactly is presbyopia and how it changes the eyes as we get older.
How does Laser Blended Vision work?
PRESBYOND® Laser Blended Vision — a treatment pioneered by Professor Dan Reinstein Reinstein and implemented by Carl Zeiss into their laser — can significantly reduce, or even eliminate, the need for reading glasses, bifocals, or varifocals for many years, being able to be adjusted non-invasively if things change over time.
Thousands of patients have already benefited from this remarkable treatment, which London Vision Clinic has offered since 2004.
You may have heard that LASIK Laser Eye Surgery can’t correct for reading vision, near vision, or the effects of ageing on the eye. A widespread myth is that presbyopia is only correctable by a more invasive procedure of surgically implanting a lens inside the eye.
However, this information is significantly out of date. Over 15 years ago, London Vision Clinic’s medical director, Professor Reinstein, pioneered this method of increasing the eye’s depth of field using a revolutionary Laser Eye Surgery technique. Carl Zeiss implemented this technique in 2009 to distribute worldwide for advanced laser eye surgeons to offer to their patients.
PRESBYOND® Laser Blended Vision has major advantages over intraocular lens implants (IOLs) for patients who do not require cataract surgery. Firstly, it’s a significantly less invasive (and therefore safer) procedure. Secondly, PRESBYOND® doesn’t require the same compromises as IOLs – where multifocal IOLs can affect the quality of your vision. Thirdly, it’s more accurate than an intraocular lens and can be adjusted as the eye ages further. Only 30% of Britons require cataract surgery during their lifetimes. If this does develop, the PRESBYOND® treatment present provides even better-reading potential after cataract surgery, even if performed with standard IOLs in the NHS.
What’s more, it’s suitable for around 97% of patients with ageing eyes. In comparison, only around 60% of people can tolerate classical monovision (an alternative solution for presbyopia, which uses contact lenses or other laser systems).
PRESBYOND® Laser Blended Vision has been adopted by Carl Zeiss Meditec and programmed into their lasers, so clinics worldwide are now able to offer this option. While many Laser Eye Surgery clinics in the UK still resort to lens replacement surgery for correcting ageing eyes, London Vision Clinic is proud to offer PRESBYOND® Laser Blended Vision — a far less invasive option, suitable for the vast majority of patients.
The key advantages of PRESBYOND® Laser Blended Vision
PRESBYOND® Laser Blended Vision adjusts each eye in slightly different ways: one eye is adjusted to see mostly at a distance, and a little close-up, while the other is the opposite: mostly up close and a little at a distance.
The brain compensates for this change almost instantly, combining the two images to give much greater depth of vision, and an all-round improvement in visual acuity that means most patients can throw away those infuriating reading glasses.
- Over 98% of PRESBYOND® Laser Blended Vision patients can read normal newsprint (‘N8’).
- Over 90% of PRESBYOND® Laser Blended Vision patients can read the small print on medicine bottle inserts.
PRESBYOND® Laser Blended Vision vs Monovision and IOLs
As well as being significantly less invasive and safer than treatments that use IOLs, PRESBYOND® Laser Blended Vision is much more effective and easier to adapt to than monovision. Monovision uses contact lenses (or older laser systems) to make one eye focused on near and one eye focused on distance. Monovision is far less effective and is not suitable for all patients.
As mentioned, not only does PRESBYOND® Laser Blended Vision minimise the risks and compromises necessitated by IOLs and monovision, but studies have also shown that it’s suitable for pretty much anyone. So, while we may not be able to stop the ageing process in its tracks completely (at least not yet), we can make it much more comfortable and convenient for almost everyone. If you are one of the few per cent who can’t achieve full correction through laser eye surgery, Bioptics might be an option for you. This combines the lens’s power inside the eye with any residual refractive error corrected with laser eye surgery.
