Refractive lens surgery

About the condition | Our consultants | FAQs

SuperVision is the process of treating focusing problems by clear lens surgery. Clear lens surgery may also be called refractive lens surgery and is very useful for people with certain focusing problems.

The majority of people under the age of 50 with a focusing problem will benefit from corneal laser surgery. Those over 50 are approaching a time in their life when cataracts may be developing, where the natural focusing ability of the eye has deteriorated and such people may be suitable for refractive lens surgery.

The eye is focused by two structures at the front-the cornea and the lens. The cornea is at the front of the eye and is transparent. The lens lies behind the cornea. Removal of the natural lens and replacement with an artificial lens alters the focus of the eye. Underlying focusing problems such as short sightedness, long sightedness, astigmatism and presbyopia can be treated by inserting a lens of a specific type and power.

The process of clear lens surgery is identical to cataract surgery. The natural lens is removed via a very small incision and a new lens replaces the old one. The procedure is performed under local anaesthetic. Drops are instilled first to dilate the pupil. The stay in hospital is under 3 hours and the procedure is very well tolerated. Following the surgery, vision returns very rapidly, almost the next day. There is normally little discomfort, although the eye can be a little red for a week after the procedure. Drops need to be used for 6 weeks after the procedure.

There are many features of the surgery that need to be considered before the operation proceeds. Each person has different visual needs and each person wants different things. Before the surgery is performed, many tests and measurements will be performed. The object of these is to plan the right approach for each individual person. We use our extensive experience of over 10,000 procedures to tailor each surgical plan to each individual. Your needs and wishes are paramount.

Short sightedness, long sightedness, astigmatism and presbyopia can be treated with clear lens surgery. Consideration needs to be given to the type of intraocular lens used. A single focal lens (monofocal) will give excellent distance vision, but reading glasses will be required. There are several approaches to reduce the need for reading glasses after clear lens surgery. Multifocal intraocular lenses give a range of vision for all distances. Vision is good in the distance, for the computer and for reading. Multifocal lenses however may cause other problems, such as glare from oncoming headlights and difficulty driving at night. There are other approaches to solve these reading issues. One eye can be focused for the distance and one eye for reading. This gives virtual independence from glasses and is called monovision. You may be aware of this approach, as it is frequently used for contact lens wearers in the over 50 age group.

Whatever lens arrangement you chose, you will have a premium intraocular lens, made of a synthetic acrylic material that has a proven track record.
Refractive lens surgery is a safe procedure; nonetheless there is a small risk from the procedure, as with any operation. Sight threatening complications are rare, but can happen. Corneal refractive surgery may be required after clear lens surgery, if the perfect focus has not been achieved. This is applicable more to multifocal lenses than monofocal lenses.

Refractive surgery can provide a variety of solutions to different focusing problems. Careful assessment will confirm which is the best option for you as an individual. We will be able to share with you our assessment and advise which is the preferred option to give you the vision that you are seeking.
