Cataract Options

Cataract Technology

In the early stages, cataracts might simply require a stronger eyeglass or lens prescription, force you to turn on brighter lights, or use a magnifying glass. You might also reduce glare by repositioning lights indoors or by wearing polarized sunglasses outside. For patients with posterior subcapsular cataracts, the use of dilating eye drops can help keep their pupils large, thus allowing more light into the eyes.

Depending on the severity of your vision loss, you may be able to delay surgery for a while, but eventually, surgery may be inevitable, as lenses and glasses will never reverse the process. Talk to Dr. Peyser about when surgery may no longer be avoidable for your own safety and quality of life.

Cataract Surgery Procedure

The cataract surgery procedure is very common throughout most of the world. Dr. Peyser   makes a tiny incision on the side of the cornea, removes the eye's clouded natural lens (using a procedure known as phacoemulsification), and then replaces it with an artificial intraocular lens (IOL). Phacoemulsification is the most common technique used today. Because the incision is less than an eighth of an inch, stitches are not typically required and the eye heals quickly. In 97 percent of cases, no complications occur.

Fortunately, modern procedures are outpatient, lasting only 15 to 30 minutes, and cause little to no pain. They even allow you to return to work the same day, if you choose.

If you have cataracts in both eyes, Dr. Peyser may recommend surgery on the weaker eye first, and then complete the second round after the first eye has healed.

Intraocular Lenses (IOLs)

How IOLs Work

Cataract An intraocular lens (IOL) is the artificial lens surgeons implant to replace the eye's crystalline lens that must be removed once it becomes cloudy. The main job of the IOL is to focus light onto the back of the eye (or retina), just as a natural, healthy eye lens would.

From here, the light rays are converted into electrical impulses that travel to the brain, where they are then converted into images. If the light isn't focused correctly on the retina, then the brain can't process the images accurately.

IOLs share the same basic construction as earlier versions—a round, corrective central portion of the lens with 2 arms, or haptics, to keep it in place in the eye—but other than these shared characteristics, modern IOLs can vary widely in ' design, being made of plastic, silicone, or acrylic.

Most of today's IOLs are about a quarter of an inch or less in diameter and soft enough to be folded so they can be placed into the eye through a very small incision.

Types of IOLs

The most common type of IOL is called a posterior chamber lens, meaning it is placed behind the iris within the capsule where the natural lens used to be. When it is placed in front of the iris, as might happen when the lens capsule is damaged, it is called an anterior chamber lens.

Here we focus on the most common type of IOL and the different lenses that have evolved from this technique:

  • Monofocal IOLs, such as the AcrySof® IQ IOL, provide a set focal point, usually for distance vision. This allows cataract surgery patients to see clearly within a range. About 95 percent of people who receive a standard IOL have their vision restored to its pre-cataract state.1 However, most patients still require glasses for reading or distance vision.
  • Monovision is a technique the surgeon may choose to perform that involves inserting an IOL in one eye for near vision and an IOL in the other eye for distance vision. This technique requires adaptation, since each eye will then be oriented towards different needs.

Advanced Technology IOLs

  • Multifocal IOLs, or advanced technology IOLs, are a newer type of lens that treats multiple focal points and reduces or eliminates the need for eyeglasses or contact lenses after cataract surgery. Part of the rapid evolution in IOL innovations, these newer lenses are made from cutting-edge materials with unique features. This is made possible through highly specialized optics that divide light and focus it on more than one point to provide a range from near to far eyesight
  • Accommodative IOLs are considered monofocal, meaning they have a fixed focal point. This type of lens is
  • designed to move in response to your eye's own muscle, which translates into the ability to see multiple focal points.


Astigmatism Correcting IOLs

In addition to treating the cataract, some IOLs can also correct astigmatism at the time of surgery. These lenses will minimize the need for distance vision glasses after surgery.

No single lens works best for everyone. Only your eye doctor can determine the most appropriate option for you and will work with you to help select the right course of treatment.
