Cataract is an eye disorder where partial or total clouding of the natural lens of the eye which leads to a progressive loss of vision
The eye has two natural lenses: cornea, which is located at the front of the eye and the lens (crystallin) located behind the iris.
Cataract is an eye disorder where partial or total clouding of the natural lens of the eye which leads to a progressive loss of vision. Light sensitivity is also another symptom of cataract.
Cataract surgery implies removing the clouding of the lens by replacing it with an artificial lens (also known as intraocular lens) in order to restore/improve vision.
The introduction of next-generation implants (multifocal and toric IOLs) allows to eligible patients not to wear eyeglasses right after the surgery.
The IOL is made of biocompatible materials such plexiglass, silicon, acrylic, hydrogel. The IOL doesn’t age and doesn’t require any specific use.
There are two kind of implants:
- Multifocal implants
Progressive multifocal lenses improve vision far away, up close and all distances in between. These multifocal implants allow the patient to lead a normal life, without wearing eyeglasses.
These lenses work through a concentric circle design which divides incident light into the focus point to be able to see from far and near. Nowadays, there are several high-quality progressive multifocal lenses with distinct features. The eye surgeon must choose between these to find the most adequate lenses to each patient.
- Monofocal implants:
Cataract surgery involves removing the clouding natural lens that impairs vision. Monofocal implants are used to correct resulting hyperopia induced after removing the natural lens.
The monofocal implant is similar to a biconvex convergent lens with a fixed focus, measured in dioptres during a biometric exam. For each implant, the eye surgeon uses a wide range of dioptres (from -10 to +30, with a 0,50D for wider ranges).
Long-term complication for cataract surgery is the posterior capsule opacification (PCO), also called secondary cataract. Eye surgeons at Brussels Vision Specialists boasts an extensive experience in the matter. This latest technique, called Bag in the lens technique, was developed to ensure long-term stability, removing the risk of PCO and restoring perfect focusing power.
