Multifocal IOL
Multifocal IOLs are artificial lenses that are implanted as replacement to the eye’s natural lens to help clear your vision after a cataract surgery or manage the vision changes that come with old age. Simply put, Multifocal IOLs have more than one focusing distance, which allows vision at both distance and near.
What Is a Multifocal Intraocular Lens (Multifocal IOL)?
These lenses allow and enable patients see far and near with greater clarity. The lenses do this by using different optical powers at various areas throughout the lens. Whenever the patient tries to focus an image however, they will have to rely on their eye muscles to move the image into place. It’s recommended that a person gets the implants in both eyes rather than only one.
It can take a little time for people to adapt to these lenses. This is because the focusing power the lenses supply differs than what patients are used to. The brain needs time to learn and compensate for the new way of focusing.
These lenses can allow people to stop wearing glasses and contact lenses. On the top layer of the lens, there are ‘rings’ etched into it. Theses rings allow images in an assortment of distances to focus on the retina.
How Cataracts Affect Your Vision
Most instances of glaucoma occur in both eyes. Their development is not even between both eyes. It is common for one cataract to be far more complex than another.
In most cases, a cataract forms when the eye lens tissue changes because of injury or ageing. These factors may cause the lens to become transparent, thicker, and flexible.
A cataract is a condition where the lens of the eye becomes cloudy. This makes it difficult to drive at night, see folks, and to read.
As cataracts grow, vision symptoms tend to become worse. When looking at the eye, it’s visibly different, and the clouding is obvious.
Cataracts can affect eyesight in the following ways:
- Night vision becomes unreliable or weaker.
- When studying or doing similar activities, the patient has to regularly increase the brightness of the environment to see properly.
- Contact lens or eyeglass prescription changes often.
- One eye develops double vision.
- Vision becomes fuzzy dim.
- Glare, and increasing sensitivity to light.
- Colours appear faded or yellowish.
How Presbyopia Affects Your Vision?
This eye condition is regarded as a natural part of the ageing process.
The symptoms associated with presbyopia include:
At a normal reading distance, eyesight is blurred. In order to read, the patient would have to hold the book further from his eyes than a normal person would. Headaches and eye strain are commonly experienced, especially when performing up-close reading or work.
People are able to start to detect symptoms as early as their 40s. It continues to advance as individuals get older.
The lens of the eye becomes much harder because individuals get old, which is exactly what causes presbyopia. The lens should change shape to allow the eyes to focus on images that are shut.
With increasing age and the lens gradually getting harder, it loses its flexibility to make the necessary contour changes. The effect of this hardening is a loss of visual acuity, and images will seem blurred.
Multifocal IOL vs Monofocal IOL
The difference between Multifocal IOL and the more usual approach to cataract treatment which is Monofocal IOL is that after undergoing surgery, there’s no need to wear prescription glasses for vision correction anymore.
Who needs Multifocal IOL
If you’re suffering from cataracts and are looking for a solution that won’t leave you dependent on prescription glasses, multifocal IOLs is the right treatment for you. However, due to its drawbacks of minimal glare and halos, this solution may not be suitable for everyone.
The patient’s satisfaction depends on careful and individualized selection based on the preexisting conditions, visual needs, and realistic expectations, and on the knowledge of the different optical designs and visual performances of the multifocal IOLs, and the proper surgical technique and eventual complications management.
