Multifocal 'Piggyback' Lens

"I’ve already had cataract surgery with a standard lens and I need glasses to read.  I would have preferred a multifocal lens and want to read without glasses. Can anything be done?" Yes. With the Sulcoflex Multifocal Lens.

Sulcoflex Multifocal Lens

The Sulcoflex Multifocal lens can provide reading vision without glasses for patients that have had standard cataract surgery in the past and currently depend on glasses to be able to read.
The lens is designed for placement behind the iris of eyes that have previously received a standard monofocal lens.  The optical principles are the same as the standard Mflex multifocal intraocular lens, but the lens is thinner and designed to rest easily in between the iris and the previously implanted monofocal lens.

How does the eye focus at different distances?

The eye’s lens has the ability to change shape.  This allows it to focus light on the retina whether the light is coming from far away (the lens becomes thin), from a near object (the lens becomes thick) or from anywhere in between.

This process is called accommodation, and is strongest in early life.  However, the lens’s ability to accommodate declines with time because of a natural loss of its elasticity.  Presbyopia is the result of these changes and is noticed when we reach our 40’s and 50’s. This is why reading glasses become necessary – they provide the extra focusing power required to see near objects.

What happens in cataract surgery?

When the natural lens becomes cloudy with the passage of time, this is called cataract.  During cataract surgery, the natural lens is removed and replaced with a clear plastic lens.  This new lens is monofocal, and is best able to focus light on the retina from one distance.  Spectacles are then required to see clearly at other distances.  Usually, patients like to see clearly in the distance and use spectacles for intermediate (computers, painting, sheet music) and near (reading) work.

As well as his full fellowships in corneal surgery and inflammatory eye diseases, Mr. Muhtaseb spent 9 months undertaking a full fellowship in refractive surgery, followed by independent practice as a Consultant in the United Kingdom.  This forms the foundation for advice and treatment that you can trust at i.Lase.

I have had successful surgery and am very happy with the result. This has been a life changing surgery for me. Thank you for a job well done!"

I was delighted with the result of my cataract surgery.  I was given a choice of lenses and detailed information before making my decision.  I am now able to drive and read without glasses. It was an entirely painless and the care I received before and after the procedures was excellent.”
