There are two main ways to treat presbyopia: the first is to wear presbyopic glasses, which is the most classic method and very convenient to use. This is mainly due to the aging of the lens, which increases hardness and decreases elasticity, so that the adjustment power decreases. The second type of surgery, which is being carried out gradually, is to improve myopia through cataract surgery, in which a trifocal IOL is implanted, which has three focal points. Therefore, after the surgery, it is possible to maintain three types of vision: distance, intermediate and near, which is also called total vision.
