Premium Monofocal Intraocular Lenses

Font Size

With ordinary NHS cataract surgery patients have a lens that sets them for distance. This is great for the majority but patients struggle with intermediate vision; using the computer, seeing labels on food goods, seeing the speedometer in the car, reading your phone etc.

To address this a whole new category of intraocular lens has been developed called the Premium Monofocals.

Elsewhere on this website you will see discussions about the bi-focal and multifocal intraocular lenses which are designed to give you spectacle independence for distance and near. These work well for most patients but there are downsides/compromises. If you are worried about the compromises or just want better functional vision at more distances, then the Premium Monofocals may be for you.

These lenses are monofocals so they do not have concentric rings on or split the light energy off into different place but instead work by clever optics called “spherical aberration” to give superb distance vision but also intermediate vision and some degree of near vision. They give better depth of focus and functional vision.

If we put these lenses into both eyes, then we can get good distance vision and you will be able to see the dashboard of your car and your phone/computer screen. If we do something even cleverer we can leave one eye a bit more short sighted (off-set) to give you even better closer unaided vision with both eyes open.

There are two lenses which I use in different circumstances, the Tecnis Eyhance Intraocular Lens™, and the Rayner EMV™. Both of these are delivering excellent results and a real “wow factor”, delivering greater flexibility of vision and a big impact on quality of life.

There are no guarantees and not all patients get the benefits of these lenses but the vast majority do. About 30% of patients are getting some reading vision without spectacles which is great but is not really the aim of these lenses.

I will now be offering all my private patients who need monofocal lenses the Premium Monofocal lenses.

Testimony from a patient who had Premium Monofocal cataract surgery under my care:

“I am writing to up date you following my operations which were 5 and 6 weeks ago.

Before the first operation I couldn't see clearly with prescription glasses to read from my computer screen, iPad or book and I couldn’t see clearly with my distance glasses either.

The transformation was dramatic after only one day following my first operation, and 5 weeks after the second operation I have good distance vision and can also see well in near and intermediate situations. I can easily read from a book, even in low light, and can see my computer screen and iPad without glasses, this has been possible from the first operation

I feel that I do not need glasses and can cope very well with in all situations without them. The only time that I do need help is in fine detail work e.g measurement at the millimetre level where I can see very clearly if I use off the shelf +1.5 lenses.

Overall, I am extremely pleased with the outcome which exceeded my expectations.”

Book an appointment to discuss these lenses with Mr Alwitry.
