You are suffering from cataract responsible for your visual disorders. Your ophthalmologist proposes surgery because it is the only way to improve your vision.
Cataract is the clouding of the crystalline lens, a high power lens located inside the eye. Cataract procedure: The patient lays on the back, in a sterile surgical environment under a microscope.
Cataract’s operation represents a major surgical procedure, because it consists of incising the eye and extracting one of its elements inside: crystalline lens.
A minimum of several hours hospitalisation is necessary. Your ophthalmologist will decide the mode of anaesthesia in accordance agreement with the anaesthetist.
The eye can be desensitised by injections of neighbourhood or solely by the instillation of drops. General anaesthesia is also possible. The choice stems from the advice of your ophthalmologist and one of the anaesthetists. Your wish is taken into account whenever possible.
The cataract extraction was performed with or without the aid of an ultrasound probe.
The envelope of the lens (the capsule) is left took in place. It is exceptional to make the total extraction of the lens.
Implantation of an artificial lens (intraocular implant) the lens is replaced with a synthetic lens placed behind the pupil. The incision is sutured to the eye or not.
Incidents or difficulties before surgery are rare and unpredictable. They sometimes lead to place the implant to the ward or to waive any location. It may be necessary to remove a small fragment of the iris and / or ablate a portion of the vitreous. The course of the intervention may be complicated by a rupture of the capsule (less than 5% of cases). The cataract extraction is sometimes incomplete. Bleeding can occur and usually resolves in a few days (in very exceptional cases, it can lead to vision loss or even loss of the eye).
In the vast majority of cases (95%), cataract surgery is painless. The vision is improving very quickly and an appropriate correction with glasses can be prescribed after a few weeks.
The presence of other lesions of the eye may limit visual recovery. Local care is reduced to the instillation of drops and wearing eye protection for a period that will be specified by your surgeon. It is sometimes necessary to ablate suturing thread. Resuming your professional occupation, operating machinery or dangerous instruments and driving are not recommended for a limited period which will be defined by your ophthalmologist. In over 30% of cases in the years following the operation, a capsule opacification may occur: the secondary cataract responsible for a new low vision. The treatment consist in achieving the coverage of the capsule by laser surgery.
