Vision correction surgery

At Spire Hartswood Hospital in Brentwood, Essex, specialist eye surgeons provide vision correction surgery for patients from Brentwood, Billericay, Chelmsford, Basildon, Romford and the surrounding areas.

Lens-based vision correction surgery (also known as premium lens exchange or refractive lens exchange surgery) removes cataracts, corrects astigmatism, and corrects long and short-sightedness, removing the need to wear glasses and contact lenses permanently.

What is lens-based vision correction surgery?

The procedure is a sophisticated development of cataract removal surgery and involves exchanging the natural lens in your eye and replacing it with an artificial intraocular lens (IOL) to restore vision. In basic cataract surgery, a monofocal (single vision) lens is used, eliminating the need for distance glasses. With lens-based vision correction surgery, the natural lens is replaced with a bespoke varifocal lens, personalised to your prescription, restoring both near and distance vision.

This type of lens surgery is generally most suitable for people over 45 years of age whose prescription is outside the treatable range of laser eye surgery, or who cannot have laser surgery due to astigmatism.

You don't have to have cataracts to have lens-based vision correction surgery but if you do, and your insurer has agreed to fund cataract surgery, you may be able to pay a 'top-up' fee to have premium lenses instead of standard monofocals.

Self-paying patients don't need an optician or GP referral to see one of our specialist eye surgeons.

Before the operation 

Before the operation, eye drops are given to dilate (widen) your pupil. This makes it easier for your surgeon to access and remove the lens inside your eye. You won’t be able to see out of your eye as it is being treated, but you may be aware of light and movement. This is normal, and to be expected.


During the operation

You will be asked to lie in a reclined position in a special chair. Local anaesthetic eye drops will be put into your eye initially to numb the outer surface and a local anaesthetic injection to the back of the eye may also be used. This can cause the sensation of pressure behind the eye which passes quickly.  Once the anaesthetic has taken effect, your surgeon will make a tiny incision on the cornea and use an ultrasound probe to break up the lens. The fragments are removed with a fine tube and a new lens is inserted. This usually takes 5 to 10 minutes.


After the operation

Immediately after the operation your eye may be covered with a protective pad. You may need to wear this for a few hours. It is normal to have slightly blurry vision for a few days afterwards. Your eye may also ache, but this generally settles down within a few days. There is a slight possibility that your eyelid or eye will be bruised, but again this should settle over a few days.


How safe is it?

 Cataract removal and refractive lens exchange is one of the most commonly performed operations and is generally safe. However as with all operations, it carries risks as well as benefits. The chance of complications depends on the exact type of operation you are having and other factors such as your general health. Ask your surgeon to explain in more detail how any risks apply to you.
