What is cataract surgery in Tunisia?
Cataract surgery in Tunisia is an ophthalmic surgical procedure which aims to remove a lens affected by cataract in order to replace it with a cataract implant (lens). Surgery is still the only possible treatment for cataract.
Cataracts are an eye disease in which the crystalline lens (the lens of the eye) becomes progressively cloudy. A normal lens is one that is perfectly transparent, i.e. it allows light rays to pass through to the retina without any obstruction. This allows the retina to receive and transmit clear visual information to the brain. A cataract opacifies the lens and thus prevents light from passing through. The light rays absorbed by the lens are then diffracted in all directions. The result is blurred vision.
With age and regular exposure to UV light, the lens loses its transparency and gradually becomes opaque. Cataracts usually manifest themselves as reduced vision, visual fog and a feeling of wearing glasses with dirty lenses, but also as discomfort when exposed to light.

Cataract surgery in Tunisia: what you need to know before you start
The first step is the pre-operative check-up. This consists of a series of general examinations (electrocardiogram, biological tests). A consultation with the surgeon and the anaesthetist must also be done a few days before the operation.
The surgeon will assess your tests, ask you questions about your general health and discuss the risks, recovery time and cost of the operation.
How is cataract surgery performed in Tunisia?
Cataract surgery is usually performed under local anaesthetic. It lasts between 45 minutes and 1 hour and requires 2 nights of hospitalization.
Cataract surgery is performed under a microscope and must be performed in a sterile surgical environment.
The operation is done in 2 stages:
- The extraction of the diseased lens. The surgeon begins the operation by opening the lens capsule to remove the opaque lens. To do this, he makes a small incision of 3 mm through which he passes an ultrasound probe. This probe breaks up the diseased lens and destroys it, and a microprobe sucks up the fragments. The lens capsule (the envelope) must be left in place to allow the new lens to be inserted.
- Implantation of the new lens. Once the diseased lens has been removed, the surgeon proceeds with the implantation of the replacement lens. Through the small incision already made, the surgeon places the synthetic lens in the capsular bag behind the pupil.
Postoperative follow-up of cataract surgery in Tunisia
Cataract surgery is very rarely painful. It is in 95% of cases painless.
Vision generally improves fairly quickly. It happens that an adapted correction by glasses is necessary after a few weeks. Your doctor will then give you the necessary prescription.
