The cataract has been corrected for many years, but this vision disease has benefited from considerable surgical growth since the 1990s with the technique of phacoemulsification. With a microincision of less than 2mm that does not require stitches, this modern technique allows patients to quickly regain a good view in very good conditions of comfort and visual performance.
At the same time, the management of presbyopia has also evolved considerably, thanks also to increasingly efficient implants, capable of replacing the lens.
These implants today make it possible to correct at the same time the cataract and the presbyopia with a good compromise of quality of vision.
Indeed, for years, monofocal implants, allowing to see well from a distance, but requiring glasses to see close, are the most proposed because simple and effective. The multifocal implants allowing to see at any distance without bezel were reserved for particular indications. However, in recent years, new generation multifocal implants have reached a stage of development and technical performance that makes them very effective and very reliable. Moreover, they provide far fewer side effects than their elders and the quality of vision obtained is close to the best standards.
One could compare this evolution with that of the progressive lenses of glasses that have greatly improved, now offering a better quality of vision and more comfort.
As a result, presbyopia implants are offered to a wider population. That said, they are not suitable for all patients. There are selection criteria to respect: retina in perfect condition, initial visual defects of refraction in acceptable standards, etc. For example, it is more difficult to correct a patient with a very strong astigmatism.
Surgery of cataract and presbyopia: what is the principle of intervention?
In the context of cataract surgery, the lens is removed and replaced by an implant. To treat presbyopia concomitantly, a multifocal implant can be used to correct both distant vision and near vision.
Technically, a microcision (1.8 to 2 mm) is made by which the crystalline lens is removed. The implant is then injected, which is deployed in the eye. Visual recovery is excellent and fast since the incision is so small that no suture is needed. The adaptation is almost immediate: the patient mostly finds the vision a few hours later, if not the next day.
This procedure is very common, it is painless and lasts only ten minutes.
Can we systematically go without glasses?
In 95% of cases, cataract surgery, when combined with presbyopia, eliminates the need for glasses. Some patients, however, choose to wear a small correction to refine their vision under special circumstances.
