Cataract Overview

Cataract surgery is a procedure to remove the lens of your eye and, in most cases, replace it with an artificial lens. Normally, the lens of your eye is clear. A cataract causes the lens to become cloudy, which eventually affects your vision.Cataract surgery is performed by an eye doctor (ophthalmologist) on an outpatient basis, which means you don’t have to stay in the hospital after the surgery. Cataract surgery is very common and is generally a safe procedure.

Why Cataract Surgery

Cataract surgery is performed to treat cataracts. Cataracts can cause blurry vision and increase the glare from lights. If a cataract makes it difficult for you to carry out your normal activities, your doctor may suggest cataract surgery.When a cataract interferes with the treatment of another eye problem, cataract surgery may be recommended. For example, doctors may recommend cataract surgery if a cataract makes it difficult for your eye doctor to examine the back of your eye to monitor or treat other eye problems, such as age-related macular degeneration or diabetic retinopathy.In most cases, waiting to have cataract surgery won’t harm your eye, so you have time to consider your options. If your vision is still quite good, you may not need cataract surgery for many years, if ever.

When considering cataract surgery, keep these questions in mind:me.

  • Can you see to safely do your job and to drive?
  • Do you have problems reading or watching television?
  • Is it difficult to cook, shop, do yardwork, climb stairs or take medications?
  • Do vision problems affect your level of independence?
  • Do bright lights make it more difficult to see?

Choosing IOLs

Today there is a wide variety of premium IOLs to choose from. The best intraocular lens for you depends on many factors, including your lifestyle and your specific visual needs.The following is an overview of premium IOLs.

During your preoperative exam and consultation, your cataract surgeon can help you choose the best IOL for your needs, as well as additional cataract surgery costs involved if you choose one of the following premium lens implants.

Aspheric IOLs

Traditional intraocular lenses have a spherical optical design, meaning the front surface is uniformly curved from the center of the lens to its periphery. Though a spherical IOL is relatively easy to manufacture, this design does not mimic the shape of the natural lens inside the eye, which varies in curvature from center to periphery. In other words, the eye’s natural lens is aspheric (“not spherical”).

Toric IOLs

Toric IOLs are premium intraocular lenses that correct astigmatism as well as nearsightedness or farsightedness.

Like toric soft contact lenses, toric IOLs can correct astigmatism because they have different powers in different meridians of the lens. They also have alignment markings on the peripheral part of the lens that enable the surgeon to adjust the orientation of the IOL inside the eye for optimal astigmatism correction.

Accommodating IOLs

Conventional spherical IOLs are monofocal lenses, meaning they are designed to provide clear vision at a single focal point (usually far away for good driving vision, for example). With conventional IOLs, typically you must wear eyeglasses or contact lenses in order to use a computer, read or perform other close-up tasks within arm’s length.

Accommodating IOLs are premium intraocular lenses that expand the range of clear vision with both an aspheric design and flexible “haptics” — the supporting legs that hold the IOL in place inside the eye.

These flexible legs allow the accommodating IOL to move forward slightly when you look at near objects, which increases the focusing power of the eye enough to provide better near vision than a conventional monofocal lens.

Multifocal IOLs

Multifocal IOLs are another category of presbyopia-correcting IOLs that can decrease your need for reading glasses or computer glasses after cataract surgery.

Like multifocal contact lenses, these premium IOLs contain added magnification in different parts of the lens to expand your range of vision so you can see objects clearly at all distances without glasses or contact lenses

Your cataract surgeon can help you decide if you are a good candidate for multifocal IOLs at your preoperative exam and consultatio
