What does cataract mean?

The natural crystalline lens becomes opaque and is removed in a surgical procedure to be replaced by an artificial lens. The artificial lens is called intra ocular lens, abbreviated IOL.

IOLs must be capable to adopt the optical function of the crystalline lens to the extent possible, to correct vision errors and to meet the individual visual expectations of the patients. In other words: function-oriented IOL aim to restore Optimal, Natural Vision (ONV).

Optimal, Natural Vision describes the optimal individual solution for the cataract patient after cataract surgery.
In most cases, a Basis IOL enhanced by individual functions will lead to natural visual capability without eyeglasses. The combination of a Basis IOL together with an AddOn IOL (that is fixated in the sulcus) offers even more individualised possibilities for the patient to achieve Optimal, Natural Vision.

These high demands are met by 1stQ's function-oriented IOL system Qfunctional. Each IOL has distinct functions. The surgeon determines the best-suited IOL in accordance with the specific requirements.

What does Optimal, Natural Vision (ONV) after cataract surgery mean? What are the visual functions that get lost during a cataract procedure and - much more important - which functions could be restored by implanting an artificial lens?
