Topcon Launches The First High-Definition IOL For The Simultaneous Correction of Presbyopia and Astigmatism
In September 2010 Topcon launched the LENTIS Mplus Toric intraocular lens (IOL), designed to provide astigmatic patients the advanced benefits of Topcon’s patented high-definition LENTIS Mplus technology. The company will officially present the lens to the market at the United Kingdom & Ireland Society of Cataract & Refractive Surgeons (UKISCRS) meeting in Brighton from the 11th to 12th of November. The new lens will serve all presbyopic patients - that is, anyone in their mid to late forties and over - with astigmatism.
The LENTIS Mplustoric combines Topcon’s LENTIS Mplus lens with the toric functionalities of the Tplus series, thereby creating an optimal lens. The LENTIS Mplus, which launched in July 2009, has been fitted in over 3,000 patients across the UK and has revolutionised presbyopic treatment. Clinical trials have shown a reported rate of 95% patient satisfaction. Unlike other multifocal IOLs (MIOLs), it has a unique sector-shaped near-vision segment and uses only one transition zone, allowing for seamless transition between the near, intermediate and far vision zones and minimal to no risk of halos and glare in patient vision. LENTIS Mplustoric benefits from this same core design but offers a tailor-made solution for patients that suffer from both presbyopia and corneal astigmatism; the resulting vision is extremely sharp and clear.
Professor Sunil Shah, Consultant Ophthalmologist at the Midland Eye Institute comments, "The LENTIS Mplustoric is simply the best all-in-one lens solution combining presbyopia correction with astigmatism. It is a major technical step forward for the IOL industry as it is the best combination of two highly advanced technologies. This lens has enabled us to better correct the vision of a wider range of patients and the outcomes have so far been remarkable."
The LENTIS Mplustoric corrects the common problems seen with the currently available “ring” system. For example, when driving in twilight or central headlight conditions, patients will see reflections, image jumps and loss of contrast sensitivity. The new “single transition zone” lens prevents this and also inhibits ghost images and double vision. LENTIS Mplustoric is made of the well-known Hydrosmart® acrylic material which guarantees excellent biocompatibility. The implantation procedure is also simplified by the predefined position of the near-vision segment and customised toric, and the plate haptic design ensures a high degree of rotational stability. This new lens stands out for its pupil independence, aberration neutrality, the guaranteed addition of three diopters, and above-average patient satisfaction.
Gloria McCall, Topcon Surgical adds, “Topcon is excited about the launch of the LENTIS Mplustoric and looks forward to presenting it to the UK’s top ophthalmologists at the UKISCRS meeting in November. The new lens offers high-definition glass-free vision to patients who would previously not have been suitable for our leading LENTIS Mplus design.”
Dr Richard Prew, a 54-year-old dental surgeon based in the West Midlands, had sight problems for 35 years. He went from wearing glasses at the age of 19, to contact lenses at 21 and on to bifocals in his 40s when his near-vision worsened. When the vision got even worse, he turned to the experts for advice. He says, “My consultant ophthalmologist told me that laser refractive surgery was not suitable for me, as he couldn’t guarantee that I wouldn’t have to wear spectacles post-operatively. He recommended the clear lens extraction procedure and to have the LENTIS Mplustoric lens fitted in both eyes.”
Dr Prew underwent surgery on his first eye on Wednesday, June 30th of this year. He explains, “There was a little short-lived discomfort afterwards and the vision was perfect by Thursday morning.” The surgery to his second eye took place two days later. He says, “There was no post-operative discomfort and the vision was perfect by the afternoon. Due to my rapid recovery, I was able to enjoy some weekend social arrangements that were on hold. In order to avoid the risk of post-operative infection, I had decided to return to work one week later; however, I was amazed by my speedy recovery and how instantly my vision was corrected.”
“I am also a member of the City of Birmingham Symphony Orchestra Chorus. As a singer, I have to be able to use close vision to read the music score and then, in a moment, far sight to see the conductor who, at times, can be a very long way away! Reading the Maestro’s direction, gestures and expressions is crucial to interpret the music effectively. Being able to see clearly both near and far without having to wear glasses or lenses is absolutely remarkable and makes the experience more satisfying and enjoyable.”
