With age the natural lens in your eye changes and influences your near sight and ability to read. This is a natural process called Presbyopia.
Loss of near vision after cataract surgery depends on the type of lens which is implanted in your eye.
Loss of near vision after cataract surgery may be very frustrating but luckily it is a problem which is easy to overcome.
During cataract surgery, the natural lens is replaced with an artificial lens.
There are a few different types of IOL lenses which will influence your near vision.
In order to achieve clear vision for near the lens must accommodate.
Accomodation is the ability of the eye to change its focus from distant to near objects (and vice versa). This is achieved by the lens changing its shape. This allows adjustment of the optics of the eye to keep an object in focus on the retina as its distance from the eye changes.
Since there is no ability to accommodate with an artificial lens, near vision is not achieved naturally. Therefore, you will most likely experience loss of near vision after cataract surgery.
Dealing with loss of near vision after cataract surgery is influenced by the type of lens implanted.
Among the different options is a Monofocal IOL, which provides good distance vision and most patients will not need distance glasses for daily activities. However, these patients will typically require reading glasses in order to have clear vision for near.
Another type is a Multi-focal IOL which provides good distance and near vision with less dependence on glasses. This lens has different focal lengths which allows clear vision at all distances. This IOL overcomes the issue of the lens not being able to accommodate and allows focused near vision.
