Presbyond LBV can help resolve presbyopia with little compromise
Presbyopia is when the eyes gradually lose the ability to see things up close. It is a normal part of ageing and starts getting noticeable around the age of 45.
The condition is caused by a gradual loss of amplitude of accommodation that is provided by the crystalline lens, and presbyopic individuals start holding reading material further away in order to see clearly. Due to an ageing population, presbyopia now represents one of the largest groups of patients suffering from a refractive error.
As it is not possible to restore accommodation, current treatments focus on compensating for the lack of accommodation by providing a different refractive power at distance and near. The challenge for such treatment options is to provide both distance and near vision while simultaneously maintaining optical quality with particular regards to contrast sensitivity and night vision preservation.
