Our eyes function very much like a camera. You have two natural lenses in each eye. One lens on the surface (cornea) of your eye, and a second lens within your eye, called the crystalline lens. Together these lenses focus images inside the back of your eye on the retina. At birth, our crystalline lens is clear. As we begin to age, it yellows and begins to harden. When it becomes cloudy, it is defined as a cataract and begins to interfere with the quality of our vision.
Everyone at some point will develop cataracts as they age. Age-related cataracts may develop during the middle age years, but typically they only begin to affect vision after age 60.
Cataracts are also caused by health conditions like diabetes, eye injuries, prolonged use of steroid medications, UV ray exposure and tobacco use.
Symptoms of cataracts include images becoming blurred, bright colors becoming dull, and seeing at night becoming more difficult. It may also be the reason your glasses do not seem to help keep things in focus as well as they used to. As a cataract begins to develop over time, people tend to accept and adjust to the decline in their lifestyles.
Removal of cataracts is crucial to prevent severe loss of vision and the debilitating effects that this common condition can cause. Recent innovations in cataract surgery now make it possible for cataracts to be removed with greater precision and accuracy. Cataract surgeons at Barnet Dulaney Perkins Eye Center are some of only a few in the U.S. to offer cataract surgery treatment with the LenSx® femtosecond laser.
Traditional cataract surgery involves the use of a surgical blade to perform corneal incisions and anterior capsulotomies of the eye, ultimately making it possible to remove the cataract. The LenSx® femtosecond laser is designed to improve precision and reproducibility during certain challenging and critical steps of cataract surgery that are currently performed manually. Because this technology allows for laser precision during these steps, the LenSx laser may contribute to improved surgical outcomes.
The LenSx® femtosecond laser utilizes a beam of laser light to create the necessary incisions for cataract surgery. An advanced computer-guidance system, controlled by one of our experienced cataract surgeons, directs the laser over the eye to provide the most precise and accurate results for each individual patient. This makes it possible for the successful combination of the surgeon’s skills with state-of-the-art technology to produce extraordinary results. The LenSx® femtosecond laser may also be able to better manage astigmatism than other types of cataract surgery.
After the LenSx® femtosecond laser procedure is complete and the cataract has been removed, our surgeon can place a refractive lens implant inside the eye to improve your vision.
Removal of cataracts is only the first step in setting you on the road to better vision. Refractive cataract surgery removes the cataracts, and then replaces your natural lens with an intraocular lens (IOL) implant, capable of reducing your dependence on corrective eyewear such as glasses or contacts. Our doctors can talk with you about your lens replacement options at your initial cataract surgery consultation.
Multifocal or Accommodating Correction
Where a basic lens provides single focus distance vision, an advanced technology lens such as a multifocal or accommodating IOL, will be the best choice if you want to maximize your ability to focus at varying distances while minimizing your dependency on glasses.
Previous lens replacement surgery technologies provided only one focal point: distance; leaving people dependent upon reading glasses or bifocals. Recent advancements in multifocal technology now make it possible to read the words on prescription bottles, magazines, newspapers and computer screens without magnifying glasses or bifocals (even trifocals), while clearly seeing objects at a distance. These lenses have the ability to consistently offer improved vision at various ranges – near through distance. Your doctor can discuss which lens will best address your visual demands and lifestyle.
Distance and Astigmatic Correction
Today’s lens replacement patient demands excellent vision after surgery. Many people with astigmatism (irregular shape of cornea that requires glasses for correction), may elect for a lens that addresses astigmatism providing natual distance vision. The most advanced method of distance correction uses a lens called a toric lens. The toric lens incorporates unique optics to compensate for specific deficiencies in your vision. Astigmatism correction may be the best choice for you if you would like to further improve your quality of vision and reduce your dependency on glasses.

A Revolutionary New Technology to Optimize the Best Possible
Vision During Cataract Surgery
Barnet Dulaney Perkins Eye Center is proud to announce yet another FDA approved technology aimed at improving vision with cataract surgery. This new device is called ORA., Optiwave Refractive Analyzer.
ORA provides an analysis of your eye during cataract surgery that is not possible with conventional measurements and instruments. The technology works by directing an invisible beam of low intensity light into the eye during the cataract surgery. This light then reflects back from the eye and sensors within the ORA device analyze the eye’s unique optical characteristics. This information then allows our surgeons to choose the most accurate intraocular lens implant and more accurately correct astigmatism for every patient who chooses to use this technology.
Ideal candidates are patients who want the most accurate results, patients who choose advanced technology implants like multifocal, accommodative and toric implants, patients who desire more accurate astigmatism corrections, patients with prior PRK or LASIK and in conjunction with LenSx (laser cataract surgery).
For more information about the ORA and what it can do for you please feel free to discuss this with our cataract refractive team.
