To date, surgery is the only option for treating cataract. In most cases, however, surgery does not have to be performed immediately. Visual requirements vary from person to person. And cataract is not “dangerous” — surgery fully restores vision. If the clouding of the lens and the reduction in visual performance do not cause any impairment in everyday life, it may be sensible to wait and monitor its progression. However, there are clear studies showing that as cataract progresses, the risk of falls increases, accidents and bone fractures become more frequent, and this also leads more often to permanent impairments and lasting disability. If the cataract is already very advanced, the surgery also becomes more difficult and riskier. For this reason, there are also well-established international guidelines on when cataract should be operated on. In all cases, however, the decision remains an individual one.
