Cataracts & Lens Implants
What is a Cataract?
Cataracts alter the clarity of the natural focusing lens of the eye. The lens becomes harder and progressively clouded reducing the brightness, clarity, colour and detail of vision. It affects 75% of people aged 60. Cataract surgery is the most commonly performed operation worldwide.
Pre-Operative Examination and Assessment.
This consultation confirms the diagnosis, determins the necessity of cataract surgery and rules out co-existing disease.
The procedure is fully explained and discussed with the patient.
The session also includes eye measurements and implant lens power calculations.
All this is done personally by the surgeon to ensure the highest possible standards are maintained.
Lens implants are necessary to restore focus to the eye.
The artificial lenses used are made from hydrophobic acrylic materials and are the finest quality.
Cataract surgery is performed under local anaesthesia and as a day case operation.
If the patient is apprehensive and worried, a short acting intravenous sedation can be administred to make the operation less stressful for the patient. This form of anaesthesia is very popular. General anaesthesia is rarely used.
The whole procedure takes about half an hour.
Cataract surgery is a very reliable procedure with a low complication rate. Significant complications occur in 0.2% of cases. Serious complications such as infections occur one per 3500-5000 cases and haemorrhage one per 5000-8000 cases.
Post Operative Care
Drops are used 4 times per day for 3 weeks.
The patient is seen by the surgeon at 1-2 days and 2-3 weeks after the operation.
