Zero infections at SNEC last yearThe Singapore National Eye Centre (SNEC) is making waves for its efforts at keeping infections at bay. After 17 patients developed an inflammation over two days. The cause was later pinned down to a dye used in a new pen to mark the patients ' eyes before surgery. The dye was found to be toxic. However, the 5,000 Lasik operations performed last year found no incident. Nearly 17,000 Cataract and Lasik operations was recorded a zero infection rate. A zero infection rate is rare said the experts. Dr Chan Tat Keong, a senior consultant at the centre, added that the prevention of infection from cataract surgery is considered the 'gold standard' internationally for measuring eye surgery success, because many more such procedures are done than any other eye operations.
Cataracts are the leading cause of blindness worldwide , according to the WHO, which estimates that 15 million cataract procedures are performed yearly. Renowned opthalmologist Arthur Lim, who now chairs the Singapore Eye Research Institute, said a stringent infection prevention programme and state of the art research facilities had enhanced the centre's reputation as a world leader in the field of opthamology. However, Prof Tan conceded that maintaning zero infection rates, while ideal, would not be achievable every year given the high volume of operation s performed.
my opinions
Going for this kind of surgeries can lead to bad results as it can cause blindness according to the research i went.

Cataract surgery is quite safe. However, like any other procedure, it's not 100% risk-free. Patients with pre-existing diseases such diabetes, high blood pressure and other eye diseases such as significant astigmatism would have a higher risk of developing complications. Possible complications include infection, inflammation of blood vessels, post-operative glaucoma, retinal detachment, malposition or dislocation of the implanted lens and posterior capsule opacifications, all of which can lead to vision impairment.

Causes of Cataract
Cataract Symptoms, Causes, Remedy and Diet Deterioration in the nutrition of the lens
There are three factors which contribute to the loss of transparency of the lens. These are deterioration in the nutrition of the lens which diminishes the vitality and resistance of the delicate lens fibres; deposits of acids and salts between the lens fibres which have an irritating effect on the lens tissues and exert an increasing pressure on its delicate fibres, gradually destroying them; and disintegration of lens fibres which cloud the entire lens in the absence of appropriate measures.
Poisons in the blood stream, faulty style of living
As in the case of most diseases, poisons in the blood stream due to dietetic errors and a faulty style of living, are the real cause of cataract. The toxic matter in the blood stream spreads throughout the body to find shelter in any available weak spot. It strikes the lens if it has become weak through strain, excessive use of the eyes, and local irritation. The condition becomes worse with the passage of time and then a cataract starts developing.
Stress and strain, alcoholic drinks, certain physical ailments
Other causes of cataract are stress and strain; excessive intake of alcoholic drinks, sugar, and salt; smoking; certain physical ailments such as gastro-intestinal or gall-bladder disturbances; diabetes; vitamin deficiencies; fatty acid intolerance; ageing; radiation; side-effects of drugs that have been prescribed for other diseases.
