What is a Lens?
As a commoner, when you hear about lenses, you think of those used as an alternative to eyeglasses. But, when it comes to eye lenses, their design is such that it both accepts and bends light. These particles of light then get pushed to the back of your eyes, where the brain converts them into images. However, when factors like age and underlying health issues come to the fore, your eye lens can get cloudy and blurred. Thus, calling for the need for corrective eyewear or surgery.
When it comes to cataract surgery, the ophthalmologist places another lens inside your eyes to sharpen the particles of light as they pass through. You will find most eye doctors using silicone or acrylic lenses for cataracts. They get coated with protective material to shield your eyes from the damage caused by harmful sun rays.
Today, you will learn more about the different lenses and the ones best suited for cataracts.
Best Lens for Your Cataract Surgery
How can you decide the best lens for you? Firstly, an expert opinion on the subject matters as it concerns your eyes and your vision. Secondly, with multiple options available, you can choose a lens that’s best-suited for your eyes. While your eye doctor may suggest the right kind of lens for you, the decision remains personal, and what you need from the eye surgery matters in this case.
You will come across four types of lenses used in cataract – monofocal, multifocal, accommodative, toric – designed to make your eyesight sharper and less blurred. Here, you can take a comprehensive look at all of them.
- Monofocal Lens – It is the most common lens used in cataracts. The primary purpose of the monofocal lens is to give you crisper, clearer vision at a predetermined distance range. Therefore, if you need to look closer or farther away from this set distance, you might need your eyeglasses.
In some cases, people who have opted for monofocal lenses can read, knit, or work on a computer without the help of glasses. However, when they need to watch things at a distance, they need to wear their glasses.
- Multifocal Lens – In your life, you will find some people who willingly wear glasses if the need arises. However, you will also find people opposed to the idea of depending on any corrective eyewear to help them see clearly. In the latter, the multifocal lens proves beneficial and has appeal too.
A multifocal lens has zones of focus. When your eyes get familiar with these lenses, the brain learns to select the clear-cut vision automatically. However, this lens has its challenges, and you need to consult your doctor to know if this is the right kind of lens for you.
- Accommodative Lens – If you’re uncomfortable wearing glasses or with the idea of using multifocal lenses, this is the perfect option for you. It moves or shifts in shape similar to your natural lenses and allows you to see things clearly, whether they’re near or far away.
However, some researchers suggest that eye exercises enhance the workability of accommodative lenses. So, before you opt for them, check with your doctor if you’re eligible.
- Toric Lens – In the case of astigmatism, these lenses will work wonders for you. Not unlike an accommodative lens, the toric lens changes shape. But, its design is such that it corrects your specific refractive error.
Some researches and studies suggested that a maximum percentage of people with toric lenses did not feel the need to wear glasses to see clearly at a distance, while others did not need reading glasses.
While the way cataracts get treated nowadays change with every innovation, the procedure remains the same. However, with new lenses to choose from, it gives the eye specialist a range of options that could work well for a particular patient. Whether you pick the lens or trust your ophthalmologist, select one that works well for you.
