Despite modern diagnostics, approximately 10-20% of patients have minor residual refractive defects after cataract surgery. Depending on the type of implanted lens and the patient's requirements, this can be disruptive. Especially with multifocal lenses, even a slight defective vision can significantly reduce the desired ability to see. This can be corrected with a further minor procedure.
The most common type of post-catarcade surgery for inconspicuous corneas and adequate wetting
For thinner or irregular retinas or when tear production is reduced
A second artificial lens is implanted between the first IOL and the iris.
The risks correspond to the risks of cataract surgery.
The additional IOL is implanted in the capsule bag in addition to the existing artificial IOL.
The risks correspond to the risks of cataract surgery.
In the case of major residual vision defects, so-called “refracive surprise” or if the patient is unable to cope with the multifocal IOL at all, a lens change is evaluated. This involves cutting the lens in the capsule bag with small scissors and then removing the individual parts via a small incision on the cornea.
The risks generally correspond to the risks of cataract surgery. Since the IOL grows together with the capsule sac after just a few months, explantation is significantly more complex than implantation. This can damage the capsule bag so that the new lens does not have to be attached to the capsular sac as planned but to the ciliary sulcus or to the iris. In these cases, vitreous bodies may have to be removed, which may require further intervention.
