Permanent absence of glasses with implanted lenses – Portal of naturopathic specialists

Life without glasses

From the age of 50, the risk of developing cataracts from visual disturbances increases. Between the ages of 65 and 75, around 90% of all people have it – often without knowing it. For several years, it has been possible to use special lenses in cataract surgery, which allow people with the condition to see without glasses. An ongoing study now shows that an improved form of such lenses can also remedy presbyopia, which already sets in from the age of 40.

Researchers at the University Clinic of Ophthalmology and Optometry Vienna have shown that new and improved multifocal lenses can permanently correct both cataracts and age-related myopia or hyperopia. So-called multifocal lenses allow you to see near and far without glasses. The research results were recently presented in the American Journal of Ophthalmology and the British Journal of Ophthalmology.

The right choice of lens

In addition to impaired myopia or farsightedness, other special lenses can also correct astigmatism. According to the task force, these types of artificial lenses are increasingly popular. The latest research results show that artificial lenses are stable in the eye and well tolerated.

Three birds with surgery

Lenses are used during day surgery. At the same time, cataracts, presbyopia and astigmatism can be eliminated. “The full effect of these glasses is highly dependent on their stable fit,” says Christina Leydolt of the study team. Only optimal rotational stability allows those affected to see well and can prevent them from further operations.

No need for glasses anymore

“We have developed a very precise method to measure and analyze the stability of toric lenses,” emphasizes Leydolt. In this way, the right lens implant can be adapted to each person in order to achieve optimal correction of the visual impairment. “For patients, this means good vision without glasses after cataract surgery and no other corrective intervention,” explains the ophthalmic expert.

For the first time, presbyopia can be treated permanently

The team’s current research results show that the new multifocal lenses can also correct presbyopia, which many people already have by the age of 40. A new generation of these special lenses not only improves near and far vision, but also medium distance vision.

Multifocal lenses are more and more common

“The range of different multifocal lenses is growing steadily and is geared towards the growing needs of patients,” emphasizes Leydolt. So-called intermediate vision at distances between 50 and 80 centimeters is particularly important because it is the average distance between people and screens of laptops and PCs. This type of vision is currently the subject of another study on which the Leydolt team is working. (v)
