Multifocal lenses are implanted through a small incision at the edge of the cornea. In this way, it allows you to see far and near clearly. These lenses have several focal points. This naturally means that all daily activities after refractive lens replacement can be performed without glasses, as several spectra are covered. It should be clear from what distance the vision without glasses is aimed. However, which activities are carried out should be discussed first. Accordingly, it should be decided whether the multifocal lens is sufficient or not.
The UV filter prevents damage to the eye. However, it provides additional protection against harmful effects for the retina. But above all, it provides a better contrast sensation in some cases.
Multifocal lenses are lenses produced to correct more than one vision disorder. They are used to correct problems such as hyperopia, that is, nearsightedness, myopia, i.e. short-sightedness, and age-related presbyopia. Presbyopia is called near vision disorders. It is not a visual defect, it occurs due to the gradual hardening of the lens of the eye with age. It usually begins to occur after the age of 40, becomes permanent at the age of 60 and there is no progression.
Presbyopia is very easy to notice. As time goes by, it is difficult to see closely, in short, presbyopia is an eye problem that affects everyone who reaches the age of 40-45. At this point, nearby objects begin to appear blurry. You may need to extend your arms beyond your eyes to see the book you are reading clearly. Of course, there is a limit to extending your arms.
Multifocal lenses provide many advantages. These usually include the following advantages:
Some disadvantages of these lenses include:
After deciding to perform this procedure, we recommend that you do not drink alcohol or cigarettes until the day of the operation. However, if you are taking blood thinners, you need to stop using these medications. You should inform your doctor about your medicine. Women should not wear eye makeup when coming to the operation. On the morning of the operation, you can have a breakfast that will not disturb your digestive system. You do not need to starve because the operation is not performed under general anesthesia.
After multifocal lens surgery, patients are discharged during the day. However, there are some elements to be considered after installing a smart lens. We can list them as follows:
If you don't see an answer to your question, you can send us an email from our contact form.
You can return to your country after the multifocal lens operation. But it would be better to stay here for two or three days for the risk of developing a complication. After a day, if everything is in order, you can return to your country.
You need to be here on the day of the operation. You do not need to arrive a few days before the operation. But if you have planned a tour here, you can arrive earlier.
Multifocal IOLs reduce your need for reading glasses after cataract surgery. These implanted lenses expand your visual range. This way you can see clearly in near and far places without additional glasses.
Bifocal contact lenses are designed with a specific line between the degree of near vision and the degree of distance vision. You can move back and forth between zones, just like you do with bifocal glasses. In multifocal lenses there is a gradual transition between far and near.
Newer multifocal lenses are better than older diffraction lenses in terms of near vision, vision quality, and the risk of halos. These lenses, however, have statistically significantly better results than refractive lenses.
Some disadvantages of these lenses include: It can be difficult to get used to due to the different vision experience, during the acclimation phase, there may be a problem of night glare and misty or shaded vision, and they are more expensive due to the complexity in their design.
If someone has an ocular comorbidity in their eye, it is not suitable for a multifocal IOL. In general, this means that 50% of patients are not eligible.
There is no clear answer to this question. Because prices vary depending on some reasons. These are usually the brand of lens used, your doctor’s experience, and the quality of the clinic.
In most cases, these lenses are used to treat cataracts. However, multifocal lenses can also be used outside of cataract surgery. If you are over the age of 45 and want to correct your myopia, hyperopia or presbyopia, this treatment is a permanent and definitive treatment for you.
These lenses work very differently than regular eye lenses. It is both permanent and definitive treatment. At the same time, you don’t have to take it off while sleeping or showering.
When a multifocal IOL is implanted, sufficient near-vision must be ensured. If this is not achieved or causes halos and other vision problems, it can be removed. Instead, it can be replaced with a different IOL or a traditional single vision IOL.
The type of artificial lens implant used is not considered. For this reason, you should always expect your vision in the surgical eye to be temporarily blurred during the first week after surgery. Most patients wait about a month to get new prescription glasses after cataract surgery.
