Cataract Surgery: The Intraocular Lens Exchange Procedure
Should you be diagnosed as requiring cataract surgery and you are over 50 years of age, you can undergo a procedure known as intraocular lens exchange to restore your youthful vision. This procedure involves replacing your cloudy eye lens with a small clear artificial implant. This implant is mist free and allows you to see clearly. A benefit of undergoing this form of cataract treatment is that you will not develop cataracts in later life.
Details of the Cataract Surgery Procedure
After a suitability assessment you will attend the AVC clinic for your cataract surgery. The actual procedure takes 25-30 minutes per eye with one eye treated at a time.
A small cover is placed around the eye and a lid guard is used to allow free access for the surgeon to carry out the procedure. You will not feel any discomfort as anaesthetic eye drops are used.
First a very small incision is made through which an ultrasound probe is inserted. This probe is used to fragment the cloudy cataract lens inside your eye and the resulting fragments are removed with a fine suction device.
Next the foldable biocompatible replacement lens is inserted to replace the natural lens which has been removed.
The eye is then left to heal naturally with the incision self-sealing without the need for stitches.
After the cataract surgery procedure you can leave the clinic the same day, returning 24 hours later for a follow up assessment.
The intraocular lenses used in cataract surgery can have a multifocal element, this allows the patient to not only have clear distance vision but also have near vision correction. In rare cases a small prescription may remain which can be treated with laser but for the vast majority of patients multifocal lens implants provide clear vision at all distances.
You can also have cataract surgery with a monofocal (distance only) implant. This will provide you with glasses-free distance vision and a small prescription for reading in each eye. The individual type of lens recommended for your cataract surgery will be discussed prior to your treatment at the suitability consultation.
Recovery from Cataract Surgery
Once you have had your cataract surgery, you will be surprised at how quickly you can be up and running .For most patients distance vision is noticeably improved the day after cataract surgery, with intermediate and close vision improving over a couple of weeks. Studies have shown that optimum visual results are achieved once both eyes have undergone the procedure.
Most patients are able to undertake light physical activities within a few days, and you should be up to doing most activities including sports by the three week mark. Cataract surgery is not only fast to perform; the recovery times are nice and quick also.
