Premium intraocular lenses are lenses that are implanted inside the eye, allowing the patient to see well at all distances without the need for glasses.
This type of lenses correct multiple vision pathologies, such as myopia, hyperopia, astigmatism and presbyopia or eyestrain. Only in some cases the patient may require a little help for certain visual activities.
Currently, there are multiple types of premium lenses on the market, which makes it possible to choose the best one for each patient. In order to make the right choice among all the options, it is essential to carry out a personalized study of each case.
How are intraocular lenses implanted?
The procedure is a small surgery where the crystalline lens is removed and the premium intraocular lens is implanted. The crystalline lens is a natural lens of the eye that, with time, becomes rigid and loses transparency. This causes presbyopia and also a decrease in vision. On the other hand, when the crystalline lens is opacified, it is called cataract.
The removal of the crystalline lens is performed with ultrasound and the intervention is generally carried out with topical anesthesia in the form of drops. After the treatment, and following a post-surgical check-up, the patient can go home.
The advantages of intraocular lenses
Premium lenses are suitable for all patients with cataracts or presbyopia who want to do without glasses. However, there is a minimum condition to be a candidate for this type of surgery and that is not to present any other ophthalmologic pathology.
Although other types of intraocular lenses, called monofocal lenses, can be implanted, they give a good result for distance vision, but they have a disadvantage compared to premium intraocular lenses: the patient will need glasses for near vision, for example for reading, and for intermediate vision, for using the computer.
Finally, the result of intraocular lens surgery is forever, i.e., once the patient has had the lens removed, he or she cannot develop cataract again. However, over time, the support on which the implanted intraocular lens rests inside the eye may become opacified. This is not a concern, as it is easily solved by laser treatment performed in consultation with an ophthalmology specialist.
