For some, invasive surgery is the only way to help them return to
natural vision.
However, botched surgery in India has caused a number of people to go blind, highlighting the dangers of such procedures.
At least ten people are thought to have been blinded after undergoing routine cataracts surgery in the Indian state of Andhra Pradesh.
Four patients had to have their eyes removed as a result of the operation.
Although there is little risk in most surgeries, people that want to avoid any dangers altogether may wish to consider alternative options, such as
ortho k lenses.
The overnight lenses are a completely natural way of helping vision become restored and gently help reshape the eye while asleep.
Once awake, they can be removed and
natural vision is restored.
As well as invasive surgery,
ortho k lenses can be an option for people seeking to avoid
eye laser surgery side effects.
