How Cataracts Affect Your Vision

As cataracts develop, all objects – whether near or far – become blurred and vision usually worsens. One of the results of developing a cataract is losing the ability to see in low light situations or at nighttime. Other signs of a cataract include hazy or blurred vision, colors that seem faded or not as bright as they once were, glare and/or halos from lights and frequent changes in eyeglass prescriptions.

Effects of Cataracts

Cataracts have been significantly associated with:
– Difficulty driving in the rain*
– Difficulty driving alone*
– Difficulty making left turns across traffic*
– Difficulty driving on interstates, in high traffic, in rush hour, and at night*
Drivers with cataracts are more than four times more likely to report these difficulties than drivers without cataracts.*

Cataracts & Driving Safety
• Cataracts limit freedom of travel and mobility.
• People with cataracts are twice as likely to reduce the number of days driving per week, and the number of their destinations.*
• People with cataracts are two times less likely to drive beyond their neighboring towns.*
Cataracts & Falls
• Falls are the leading cause of injury-related visits to emergency departments in the US.1
• In older people, contrast sensitivity appears to be important for maintaining balance and detecting and avoiding hazards in the environment.

Traditional Lens Implants

Traditional lens implants improve vision but still leave the cornea and lens somewhat unbalanced.  Vision with a traditional IOL is better…but not as good as it could be for most people.

The TECNIS Intraocular Lens™

The TECNIS Intraocular Lens™ San AntonioThe TECNIS™ Intraocular Lens (IOL) is the FIRST and ONLY lens implant approved by the United States Food & Drug Administration to improve functional vision and reduce spherical aberration, which is likely to provide a meaningful safety benefit for most older drivers.

The TECNIS™ IOL was developed using an advanced optical measuring system called wavefront technology.
Based on these advanced wavefront measurements, optical engineers created the patented TECNIS™ IOL with a modified prolate (curved) lens surface.

The modified prolate lens surface allows the TECNIS™ lens implant to restore the cornea/lens balance to a level more like the natural lens found in a healthy young adult’s eye instead of restoring the cornea/lens balance to a level more like that of a natural lens typically found in a healthy older person’s eye.

The result is a lens implant that helps provide safer, sharper vision in varying light conditions.

The AcrySof ReSTOR IOL

Traditionally, cataract patients had their vision improved with a monofocal IOL. Although the quality of their distant vision was excellent, most patients needed reading glasses to see near objects. The good news is that you’ve encountered cataracts at a time when intraocular lens technology has taken a giant leap forward. No longer is the objective simply to restore your distance vision with a monofocal IOL. Today, the goal is to enhance your vision with an IOL that may provide you with a full range of vision, thus minimizing your dependence on glasses, including reading glasses or bifocals.

What is Presbyopia?

When your eyes were young, your natural lens was both transparent and flexible. Because of this, your vision was most likely stable until you reached your forties. Around that time, you may have noticed that you had to hold a menu or a book farther and farther away to read it. Many people end up wearing a pair of reading glasses or bifocals to compensate for this aging of the eye. This condition is called “presbyopia” and eventually affects everyone, including those who are nearsighted, farsighted, have cataracts, or had perfect vision most of their life.

The AcrySof ReSTOR IOL

AcrySof ReSTOR IOL New BraunfelsWith more than 21 million lenses implanted, the AcrySof lens is the most commonly used IOL in the world, since they became available in 1994. Its popularity is largely due to their ability to provide excellent visual results and a high level of patient satisfaction.

In the clinical study, 80% of patients receiving the AcrySof ReSTOR IOL reported that they never wear glasses for any activities. They can read a book, work on the computer, and drive a car- day or night- and play golf or tennis with an increased freedom from glasses. In fact, patients were so pleased with their vision, nearly 94% of patients said they would have the AcrySof ReSTOR IOL implanted again, if given the choice.
