Cataract surgery: two types of implants

The choice of the implant is made before the operation with the surgeon, according to the habits and needs of each patient (reading, television, driving ...):

Classic monofocal lenses:

They require choosing between a correction without glasses from far or near.

Multifocal implants:

Increasingly used, multifocal implants make it possible to correct vision from afar or near, whether the patient is nearsighted or hyperopic. The effectiveness of this technique, however, remains imperfect. Some patients complain in fact the first months of perceiving glare during the night.

In general, it is impossible to provide a perfect correction and thus to ensure that the patient can do without glasses. In addition, these implants are incompatible with certain pathologies (age-related macular degeneration, glaucoma, retinal disease, significant astigmatism).

Operative follow-up and possible complications

Although the cataract surgery is now well controlled, it carries a risk. The most frequent (less than 2% of cases) is, during the operation, the rupture of the lens capsule. It is then necessary to carry out a complementary operation.

Severe post-operative complications are rare or even exceptional. They consist mainly of a risk of infection (1 case per 1000) or retinal detachment (1 case out of 100).

The most common difficulty is opacification of the capsule. It concerns 1 out of 4 cases and occurs in the years following the operation. This "secondary cataract", responsible for a new drop in vision, then forces to reopen the lens capsule by laser. The intervention takes place in five minutes in the office of his ophthalmologist.

In 95% of cases, the patient does not suffer from the operated eye. The vision improves in a few hours, even in a few days. Local care is reduced to treatment by eye drops for a few weeks and if necessary to a change of glasses.
A check-up visit will be made to the surgeon the day after the operation and 15 days later.
