Premium Lens Implants for Cataracts

Millions of people across the world have cataracts. A cataract scatters and obstructs light as it goes through the lens. The obstruction reduces the sharpness of the images that get to your retina. As such, the images you see are blurry.

 

Since cataracts are not treatable, the doctor removes your natural lens during surgery. In its place, he or she places premium lens implants called intraocular lenses (IOLs). The correction surgery used for this exchange is called refractive lens exchange.

 

Previously, before the introduction of IOLs, you would have to wear very thick glasses after the cataracts removal surgery. But, today, there are many alternative lenses to replace your natural ones.

 

What Is an Intraocular Lens (IOL)?

An IOL is a very tiny artificial lens implanted in your eye. It refracts the light rays as they get inside your eye and helps you to see better. Natural eye lenses are clear and allow light to pass through. But, after getting cataracts, the lenses become cloudy. Images you see become hazy or bloody, and colors lose their brilliance. But, through surgery, the eye doctor replaces the lenses with IOLs.

 

IOL lenses are made from acrylic, silicone, and other kinds of plastics. The rigid lenses are then covered in a special material that shields your eyes from the sun’s UV rays.

 

Types of IOLs Lenses

Monofocal IOLs are the most frequently used IOLs. They have only one focusing distance. They can be set only to the near, medium, or distant range. Most people opt for distance vision and augment it with eyeglasses that can focus on the near distance.

 

IOLs that have different focus distances in the same lens are either multifocal or accommodative lenses. They accord you more freedom by getting rid of your need to wear glasses. You can focus on more than one distance and have a very clear vision.

 

Multifocal IOLs: 

have both near and distance focus.

 

Accommodative IOLs:

are flexible and tend to change shape inside your eye, making it easy to focus on different distances.

 

Extended depth-of-focus (EDOF) IOLs

are corrective lenses designed for both intermediate and distance focus.
 

Toric IOLs

are special lenses designed for people with astigmatism? Astigmatism is a refractive error that results from an unevenly curved cornea. So, toric lenses are also designed to fix the refractive error.

 

Choosing the Right Premium Lens Implants

The type of IOL lenses fitted to your eye will depend on three primary factors. The first factor is your visual needs. Your visual needs revolve around your lifestyle. Consider your work and what you do for fun. If your job needs a close focus, choose lenses that have a near or accommodative focus.

 

Second, it matters whether you would be willing to put on glasses. If you don’t mind wearing glasses, you can choose IOLs with one focal distance, then boost your vision with glasses.

 

Third, the status of your condition is a critical influence. The doctor advises you on the lens to take based on the diagnosis made. That means that the optometrist will go into details, examine the advantages and the risks, then tell you what to do. The earlier the onset of the disease, the more treatment options you have.
