Are you looking for the right lens for your cataracts? No doubt, cataract is a common eye condition that affects almost all adults by age 65. It happens when the lens in your eyes becomes cloudy, making it hard to see clearly.
A combination of risk factors may increase your chance of developing cataracts, such as: excessive ultraviolet light exposure, a diet low in fruits and vegetables, a history of eye injury, certain medications, and advancing age.
An eye exam can help track the progression of cataracts symptoms and provide treatment for cataracts to help you maintain your quality of life.
An intraocular lens (IOL) is a type of implant that is placed inside your eyes during cataract surgery. The purpose of the IOL is to help you see better by restoring the functionality of your lens.
The IOL is made with a plastic or silicone material and is implanted inside your eye during cataract surgery. It is attached to your retina and lets light into your eye. When cataracts form in your eyes, the lens inside your eye becomes cloudy and hard to see through. The lens is responsible for focusing light on your retina, allowing you to see. A cataract blocks the light from being focused on your retina. There are three types of intraocular lenses: monofocal ,multifocal and toric IOL’s, which is used to treat astigmatism.
A monofocal IOL is the most common cataract surgery lens.
It has one focal length, and therefore focuses at one distance. Your visual requirements will determine whether you require close-up, medium-range, or long-distance vision. Generally, eyeglasses are required for reading or near work. For the majority of people, having their vision set for long distance is preferable for driving, walking, and seeing people away.
A toric IOL is recommended for patients who are astigmatic. It is also suitable for patients with short-sightedness or long-sightedness.
An astigmatic eye has a focusing ability that is either over or underfocused based on where in the eye the focus is being created. Toric IOLs can correct astigmatism because they have distinct focusing powers on both horizontal and vertical lines that compensate for an astigmatic eye’s lack of focus. To fully cure astigmatism, toric IOLs need to be oriented correctly.
A multifocal implantable lens is a premium implantable lens that gives both far and near vision at the same time.
With this lens, you may see nearby and faraway objects without glasses (although you may still need them for certain situations, such as reading small print). The IOL has different zones that focus light differently, splitting the light between near and far vision, which means a multifocal IOL never uses 100% of the light for far vision or near vision. Only 5-10% of those considering cataract surgery can tolerate this, because of the special optics of a multifocal IOL.
A cataract is more than just a clouding of the eye lens. It also negatively affects quality of life, eye health, and work-related functions.
The best way to live with cataracts is to maintain a healthy lifestyle. Exercising regularly, leading a balanced diet, getting enough sleep, and staying hydrated are crucial to keeping your eyes healthy. Regular eye checkups can help detect and prevent the development of cataracts. While there is no cure for cataracts, they can be treated with surgery. The best cataract lens type is the one that suits your lifestyle.
The best approach is early detection and treatment. If you are experiencing cataract symptoms such as cloudy vision, blurred vision, double vision, faded colours or poor night vision it’s best to have regular eye examinations to ensure early detection.
