Novelty in ophthalmology – Eyemax Mono lens for the macula lutea

The most modern intraocular lens Eyemax Mono

Novelty in ophthalmology!

In 2017 a new method for effective treatment of Patients with dry form of macular degeneration and other macular diseases has finally appeared. What is this method? Eyemax Mono is the world’s first macular lens widening the vision. Its implantation is a revolutionary, totally innovative and effective method of treating Patients with dry form of macular degeneration and other macular diseases has appeared.
Until now most Patients with dry form of macular degeneration would hear that “nothing can be done” to improve their vision. Even though there is no 100% effective treatment of the dry form of macular degeneration, still in Patients suffering from it and implanted with the Eyemax Mono a great improvement or recuperation of vision is observed.
The technology of the innovative Eyemax Mono lens was developed by dr. Bobby Quershi who leads the team of ophthalmological surgeons and scientists from the London Eye Hospital Pharma. It’s a team of physicians with great experience in treating Patients with macular degeneration.

In 2017 our facility became the first one in Poland to be able to use the EyeMax Mono lens in Patients with a dry form of macular degeneration, and since 2019 we have also been gaining the experience of implanting this lens in Patients with Stargardt’s Disease.

Which Patients the Eyemax Mono lens is recommended for?
The Eyemax Mono lens can help Patients with dry and some of the wet forms of the macular degeneration as well as Patients with other forms of macular diseases such as:
– diabetic macular degeneration,
– myopic macular degeneration,
– hereditary retinal degeneration such as Stargardt’s dystrophy.
The procedure of implanting the Eyemax Mono lens is suitable both for Patients who underwent the cataract removal surgery and those who did not have such procedure performed.

How does the Eyemax Mono lens work?
The lens works as a small telescope. Due to that, the image reaching the eye becomes enlarged and is then transferred to the healthy parts of the retina around the macula. This gives the Patient the opportunity to significantly improve the central vision.
Due to the fact that the EyeMax Mono lens ensures high image quality in the whole area, the brain can automatically select the image from the healthiest part of the retina.

How does Eyemax Mono lens improve vision?
By having this lens implanted, the Patient can recognize facial features, read and even drive. The percentage of vision improvement, in some people greater, in others, depends on the type and severity of the Patient’s condition.

What is the risk?
The risk of implanting the Eyemax Mono lens is no greater than the risk of cataract removal surgery, that is minor.

What is the Eyemax Mono implantation procedure?
The Eyemax Mono lens in its shape and size is no different that other lenses used in cataract removal surgeries. It is being implanted into the eye during a surgical procedure (which lasts around 30 minutes). No need to stay at the hospital overnight. Withing 24 hours after the surgery the Patient has a follow-up appointment. Recovery after the surgery is fast and does not require special medical advice being followed. For about a month after the procedure the Patient needs to apply eye drops, usually the same as those used after the cataract removal surgery.
It is recommended to implant both eyes with the Eyemax Mono lens in a short period of time. Otherwise, with each eye the Patient will be seeing images of different sizes.
After the surgery, Patients may need some time to get used to the effect of the improved vision.
It is also recommended that the Patients with the Eyemax Mono lens implanted would wait about 4 weeks before they have new glasses.

Why is it worth to have the Eyemax Mono lens implanted?
How is the Eyemax Mono lens different from other intraocular lenses? First of all:
– it improves both the distance vision and the ability to read – in most Patients the distance vision is improved of about 3 lines, and the close vision is improved of more that 2 lines on the test board. In some, the improvement reaches up to 5 lines (might be different for each Patient),
– after the Eyemax Mono lens implantation the Patients are able to read 25% faster than before the surgery,
– although the lens does not fully restore vision and does not stop the progression of the disease, it minimizes the effects of increased retinal damage and maintains the best vision your macula can achieve,
– after having the lens implanted the Patients feel more confident about their vison. Generally speaking: the image quality improvement in healthy parts of the retina occures.

The Eyemax Mono lens and the eyeglasses
The image magnifing effect of the Eyemax Mono lens can be escalated by using moderate-intensity glasses. The Patients with Eyemax Mono lens implanted generally need two pairs of glasses: one for working from close distance and the other for seeing from far.

The first contact lens

MD PhD Piotr Tesla

The first man in history who wore contact lenses was a German physician August Mueller born in Munchengladbach (1864-1949). He was inspired by his own significant sight defect (approx. -14 dioptres) which he’d had since childhood. His deliberations on the sight improvement resulted in his PhD thesis, defended on 28 February 1889 and titled “Glasses and corneal lenses”.
To create his lens Dr Mueller used casts of dead people’s eyes. Thanks to that he was able to establish the length of the radius of the corneal curve – 7.5 mm – and the lenght of the radius of the scleral curve – 14 mm. Then Dr Mueller ordered three lenses (-14.5, -15 and -19.5 dioptres) from a famous microscope manufacturer based in Berlin, Karl Otto Himler (1841-1903). The lenses were made of thin glass, around 0.3 mm thick, with carefully cut edges. The outer diameter of the lens measured between 15 and 16 mm. Its inner surface, which directly touched the eye, was divided into the corneal part (7-7.6 mm diameter) and the scleral part (13-14 mm diameter).

500 years of the history of contact lenses

MD PhD Piotr Fryczkowski

In 1508 Leonardo da Vinci (1452-1519) in his work The Codex of the Eye was considering a possibility of a sight defect correction by applying a lens directly onto the surface of the eye. He was inspired by an observation made by an English monk, Roger Bacon, who noticed that after putting his face in a glass bowl filled with water he was able to see his own shoulders.

Of course walking around with your face in a water-filled bowl (the right side of Leonardo’s drawing) would result in drowning, even if the eyesight would be temporarily corrected. Because of this, Leonardo tried to construct smaller bowls that would be put on one eye only. The most important conclusion of these experiments was the observation that the spherical surface of a water-filled bowl, which directly touches the eye, can change the optical power of the eye.

In 1637 Descartes continued deliberations on a sight correction by means of a device applied directly to the eye in his work On Means of Perfecting Vision.

Descartes assumed that prolonging the eye with a miniature telescope filled with water and topped with a lens with a curve similar to the curve of the cornea will enlarge the picture visible in the retina, correcting vision at the same time. The telescope would need to be attached to the eye at all times so the cornea would be in constant contact with water – it was meant to neutralize its optical power. Moreover, Descartes provided a possibility to regulate the length of the telescope. Apart from construction issues, a user would need to have both hands busy – one with holding the telescope close to the eye, the other with keeping the lens focused. So it looks like Descartes’ invention wouldn’t find many takers.

In 1977 J.R. Levene from the British Optical Association tried to build a model of the Descartes’ telescope which did not put its theoretical assumptions in practice. It’s worth stressing that Descartes was wrong about the way the lens worked – contact lenses correct vision not by prolonging the eye, but by changing the optical power of the cornea. He was also wrong about the construction of the device.
But an idea isn’t always put in practice.
In the end we owe the first glass lenses to two Germans. The first was Adolf Eugen Fick (1852-1937). In 1888 he published an article, headlined “Contactbrille”, in Archiv Fur Augen Heilkinde. Initially Fick was making casts of rabbit’s eyes and from them he was creating glass lenses with 19, 20 or 21 mm diameter. Then he put them on rabbits for 6 to 8 hours. There’s no need to mention that after this heavily irritating procedure the rabbits had properly red eyes.

After his successful experiments – at least according to Fick as there was no data about rabbits’ feelings on the subject – he made a lens based on a cast of a dead man’s eye and tried to wear it himself for about 2 hours. Together with Ernest Abbe, a co-owner of the Carl Zeiss AG company and an inventor in the field of optics, he created a glass lens, which he called a “glass cornea” with an 8 mm curve in the optical part and a 15 mm curve in the scleral part. He used this lens to treat keratoconus, irregular astigmatism, aphakia and myopia. His experiments were not appreciated by his peers – perhaps due to the fact that the glass cornea helped only 1 in 6 patients and it irritated eyes and caused redness.

Eventually the first contact lens aimed to correct the vision of its inventor were worn by a German physician, August Mueller, in 1889. It was much bigger (16.5 mm diameter) than modern lenses (which measure around 8.4-9.6 mm). It also covered the sclera – unlike modern lenses that cover the cornea only. The first lenses were not only too large – they were also much too heavy and were falling out from the eye. Pain and significant discomfort caused by wearing lenses could have been mitigated with drops of cocaine.

Thomas Young (1773-1829) was first to discover the cause of astigmatism and the fact that the cornea doesn’t take part in accommodation. He also confirmed the possibility of removing the optical power of the cornea through contact with water. On Mechanisms of the Eye. Bakerian lecture delivered on the 27th of November 1800, published in 1801 Phil Trans. R Soc. 16 23-88. To prove it, he took out a small lens from a botanical microscope, covered the edge of its frame with wax and filled three quarters of it with water. Then he put his eye in the water so the cornea was half way between the lens and the edge of the frame. He discovered that the eye was unable to read: it became presbyopic. An application of an additional lens reverted it to the original – or even better – focus.

Retina Ophthalmological Outpatient Clinic and Hospital in Warsaw is a modern medical facility with an excellent and experienced team of specialized physicians – including pediatric ophthalmologists. Retina opened in 2004. Since that time we have performed over 10,000 eye surgeries, hundreds of angiographic tests and ultrasounds, and have had over 15,000 patients.

The name of our hospital comes from Greek. Retina is an inner coat of the eyeball responsible for vision. A Patients’ ability to see is the most important for us, ophthalmologists. Knowledge and many years of experience help our team to achieve that goal.

We are unique in our non-standard approach to eye diseases, innovative solutions and patient-friendly approach. Knowledge and experience are not enough and need to be supported by tests, which we perform on the most up-to-date equipment.
