Sulcoflex Trifocal Lens technology at Optimax

A supplementary trifocal lens

The world of lens surgery is constantly developing, with advancements being made all the time. We like to make sure we can offer the latest lens technology to our patients at Optimax, so we’re working with Rayner, a British lens manufacturer, to bring this to you. Rayner have been around for over 70 years, and we already use lots of their lenses for our Refractive Lens Exchange and Implantable Contact Lens procedures.


The Sulcoflex Trifocal lens is particularly exciting as it introduces the concept of a lens which adapts to three separate distances: near, intermediate, and far. It is designed for people who have already had cataract treatment, but who are still struggling with their vision and might rely on glasses. The Sulcoflex Trifocal lens is a supplementary lens made to sit in front of the original lens implanted during the cataract procedure. Most cataract patients had a monofocal lens implanted to replace their natural lens. The problem with this is that it only focuses on one distance, leaving the patient still needing reading glasses following the procedure. Why not kill three birds with one stone, and correct your near, intermediate and distance vision with one lens?


Encouraging flexibility


We find ourselves in “transition” situations every single day. This is where we need our vision to switch quickly between focusing an object close to us, to one further away. We need our distance vision to focus on things more than 6.5 feet away from us, so even watching TV and then looking down at our phones will require a transition in the type of vision we use. A lot of people rely on reading glasses for this, but these can often feel a bit impractical as it’s yet another thing to carry round with you, not to mention how regularly people lose them! 97% of people don’t need glasses with Rayner trifocal technology.


Something which is particularly appealing about the Sulcoflex Trifocal lens procedure is that it’s reversible. It can be removed, replaced or upgraded at any time – and there are also no time restrictions on when you can have it implanted after cataract surgery. This provides you with a greater degree of flexibility and you can feel safe in the knowledge that if, for whatever reason, you would like the lens removed, it’s easily achievable.


How does it work?


As previously mentioned, the Sulcoflex Trifocal lens is implanted into the eye as an additional lens, to complement your original cataract lens. It sits in front of the monofocal lens and splits light at different points across the lens surface to provide multiple points of focus. Following the procedure, you might need a few weeks to adjust, reinterpret and resolve the images you see through the new lens. This is called “neuroadaptation” and is where your brain works to begin processing all images from multiple distances in sharp focus. It can take some getting used to but, according to Rayner, most people adjust within a few weeks.


Rayner make the Sulcoflex Trifocal lens from clinically-proven Rayacryl hydrophilic acrylic material for excellent optical clarity. Rayacryl is biocompatible with eye tissue, helping your eye to adapt to the lens and avoid inflammation, irritation and infection. The lens has small haptics on either side to hold it in place in the eye and prevent it from rotating into another position. The recent advancements in lens technology have ensured that the Sulcoflex Trifocal lens implantation is fast, safe, and clinically-proven. In fact, there are 41,000 Sulcoflex lenses implanted in eyes around the world!


What are the benefits?


The benefits of the Sulcoflex Trifocal lens implant are numerous! It allows you to maximise your monofocal lens which you likely received after cataract treatment and will mean you rely less on glasses. Not having to switch to using reading glasses for close-up tasks is highly convenient, and people often say that after treatment, this is what they find most life-changing! Having inbuilt visual adjustments will change your approach to countless daily tasks.  The Sulcoflex Trifocal lens has fewer rings on its optic surface than other trifocal lens implants. This means that you’ll experience fewer halos, giving you improved night vision and improved overall acuity. The procedure to implant the lens is simple and quick and serves to enhance the vision you already have.
