LASIK is known as one of the effective laser treatments preferred for the elimination of common refractive errors. Although it is generally a preferred treatment method for common refractive errors such as myopia and astigmatism, LASIK treatment may also be preferred in different situations. One of these is Presbyopia. In this article, we will talk about LASIK treatment for Presbyopia and try to explain how the method leaves an effect.
LASIK Treatment for Presbyopia: How Does It Work?
Let’s start by briefly talking about Presbyopia. In this defect, which occurs especially after the age of 40, the natural lens of the eye loses its natural flexibility. As a result of the deterioration of the natural flexibility of the lens, blurred vision problems occur in near vision.
In such patients, the treatment called Multifocal LASIK or PresbyLASIK can be applied. In other words, when we look at the general framework, LASIK application can be performed for Presbyopia.
How to Correct Presbyopia with Multifocal LASIK?
Actually, the logic is very simple. When applying LASIK in such patients, the shape of the cornea is changed to create different power zones for vision at different distances.
In the operation
- An excimer laser is used to reshape different parts of the cornea for intermediate, distance and near vision. Your brain then selects the vision zone to achieve the sharpest vision depending on whether objects are near or far.
- In order to achieve this, the laser beams are bent differently in each region during the operation and an arrangement is provided, just as multifocal contact lenses correct Presbyopia.
Just like multifocal contact lenses and progressive spectacles, it is necessary to decide exactly how the cornea will be shaped after detailed controls in order to achieve the best correction. For this, a specialist doctor control is essential.
