What are the advantages of the light adjustable lens?
The light adjustable lens is the only lens used in cataract or clear lens extraction surgery that can be adjusted after it is
implanted in your eye. This allows your surgeon to change the lens power precisely to correct for long sight, short sight
such as LASIK surgery. As the digital adjustment is so precise it is even possible to perform Wavefront treatments to the
lens to give even sharper vision. All the adjustment is carried out by a computer controlled low intensity beam of light thus
eliminating all the risks and complications associated with surgery.
Will it correct my reading vision?
Just as the light adjustable lens can be used to perfect your distance vision, it can also be used to give you good reading
vision. Your surgeon will discuss with you the many options that exist for doing so. These include blended
micro-monovision as can be achieved with laser eye surgery or bifocal/varifocal vision similar to that achieved by multifocal
implants to correct for presbyopia. Unlike all other surgical techniques available for correcting reading vision the light
adjustable lens can be adjusted more than once without surgery to give the optimal result for your individual eye.
How long does the lens last?
The lens lasts forever. It never needs to be removed or replaced. The adjustments of the lens power are also permanent
and after they have been made to optimize your vision, the lens will never again need readjustment.
Can any eye surgeon give me the light adjustable lens?
No. Only expert cataract surgeons who have the approved equipment and are specially trained in the insertion and
adjustment of the Calhoun Vision light adjustable lens can offer it to their patients. Mr Qureshi at the London Eye Hospital
performed the first Light Adjustable Lens implants in the UK and is currently the only Consultant Ophthalmic Surgeon able
to offer this surgery.
What are the risks?
As with any surgical procedure there are risks and the results cannot be guaranteed. The risks are very similar to cataract
surgery or clear lens extraction. During the adjustment phase some patients experience transient fluctuating vision for
about 24 hours. After the 'lock in' treatment some patients experience a mild red tint to their vision which again is transient
and lasts for about 24 hours.
