Cataract Surgery

Cataract Surgery


What is Cataract Surgery?

By definition, cataract surgery is the removal of the eye’s clouded natural lens, and replacing it with an artificial lens that helps restore vision to the eye.  Click to learn more about cataracts and symptoms of cataracts.

Surgery Is the Only Option for Cataract Removal

Without surgically removing the cataract, most patients with cataracts will have blurred vision, if not complete blindness. Surgically removing the cataract is the only way to restore vision and see the world clearly once again.

The cataract operation is normally an outpatient procedure, and most patients are discharged immediately after the cataract surgery.  First, a local anesthesia.  Next, the surgeon creates a very small incision in the cornea and inserts a tiny high frequency ultrasound probing device to break down the cataract (the eye’s clouded natural lens), then inserts a miniature suction device to remove the broken down clouded lens; this process is called (phacoemulsification), then the cataract surgeon with the same device replaces the clouded lens with a new artificial lens.

Although cataracts are a fact of life for most people over 50 years old, with today’s exceptional technologies, you now have the option to improve your vision at the same time as your cataract procedure.  NVISION offers advanced technology options for your cataract procedure that can help you achieve independence from corrective lenses for most, if not all, of your activities.

At NVISION, our caring staff of ophthalmologists, optometrists and clinical staff will provide you with the most technologically advanced, proven cataract and laser vision correction procedures available today.  The NVISION team can help you with your journey back to perfect vision.

NVISION’s Approach to the Treatment of Cataracts

At NVISION, we follow an effective approach that comprises of three simple steps to offer the word best treatment of cataracts. Our experienced cataract surgeons hold expertise in offering treatment for cataracts. They complete the treatment of cataracts in three steps that are as follows:

1- Creating the corneal incision

2- Breaking down and removal of the clouded lens (The cataract)

3- Replacing the cataract with a new artificial lens

NVISION’s preferred approach to the first step is by using a femtosecond laser LenSx® to make the corneal incision, break apart the cloudy cataract lens and create a perfect size capsulotomy.  LenSx, is the most advanced laser technology for cataract surgery.  This method is referred to as Laser Cataract Surgery, or Refractive Cataract Surgery.  This new method replaces the manual scalpels  which were used to create the corneal incision.  Click the links for more information about Laser Cataract Surgery with NVISION, and the difference between traditional cataract surgery and refractive cataract surgery .

The other factor that differentiates NVISION is the use of the most advanced Intraocular lenses.

The Intraocular Lens: a Replacement for Your Eye’s Natural Lens

When a cataract causes the eye’s lens to lose its clarity, the only option is to replace it with an intraocular lens (also known as an IOL), an artificial lens that replaces the patient’s natural lens and restores the patient’s ability to see.

Intraocular lenses are artificial lenses that are implanted behind the cornea during surgery. The lens is permanent (but can be surgically removed if necessary), needs no maintenance, and can remain in the eye for the patient’s entire life.

Intraocular Lenses and Your Vision

Three Different Types of Intraocular Lenses

Ophthalmologists in NVISION’s Cataract Program are exceptionally experienced, having been involved in clinical trials and the development of a variety of brands of intraocular lenses.

NVISION doctors recommend the following proven types of IOLs for their patients:

  • Standard or Monofocal Lenses (Basic Lenses) — for lens replacement. Patients can choose near or distance vision and will most likely need to wear glasses or contacts for vision correction.
  • Astigmatism Correcting Lenses
  • Toric IOLs — for lens replacement with correction of astigmatism. Patients with Toric lenses most likely will not need glasses or contacts, but they may still need reading glasses for close-up vision. Patients with astigmatism will also have sharper distance vision with Toric lenses than with standard lenses.
  • Presbyopic Correcting Lenses (Lifestyle Lenses)

Multifocal IOL — among the brands available are Restor and Tecnis

Accomodating IOLs — among the most common brands are Crystalens

All of the presbyopic correcting lenses give you a range of distance, intermediate, and close-up vision, reducing or eliminating your need for glasses or contacts, including reading glasses.

Your NVISION ophthalmologist will consult with you about which type of intraocular lens is right for you.

Refractive Lens Exchange for Patients With Other Vision Conditions

Patients who have other vision conditions can also gain vision improvement with the implantation of intraocular lenses.

Vision conditions, such as myopia (nearsightedness), hyperopia (farsightedness), presbyopia (the inability to focus close-up), and/or astigmatism(which occurs when the cornea is shaped like a football with two different curvatures, resulting in images appearing blurry or ghost-like), are generally treatable with an intraocular lenses.

Intraocular lenses are not just for cataract patients. They are also used to correct vision in patients without cataracts. Patients who have refractive lens exchange will never experience cataracts.

The surgical process is the same as cataract surgery.

How the Intraocular Lens Is Implanted Into the Eye

To implant the intraocular lens, the surgeon must first remove the eye’s natural lens. The natural lens is broken up into small pieces with an ultrasonic probe, using a procedure called phacoemulsification.

After removing the old lens material using gentle suction, the surgeon makes a small incision in the cornea and inserts the new intraocular lens through this opening, positioned exactly behind the pupil. The incision is then closed.

The entire procedure typically takes about 15 minutes and is performed under local anesthesia on an outpatient basis.

Most patients are able to return to their normal daily activities within 24–48 hours. Full recovery can take about two weeks, after which you can resume all your normal activities. Vision recovery can take up to three months. Your NVISION patient counselor will review the specific recovery process prior to your procedure.

Cataract Surgery Coverage by Medicare and Private Insurance

NVISION accepts Medicare and most private insurance plans. Medicare and private insurance will generally offer coverage only for standard monofocal lens implants. This means that patients have a choice of either improving close-up or distance vision, resulting on a continued dependence on glasses or contact lenses for their vision needs.

NVISION offers advanced lens technology as an exciting option for your cataract procedure. Using these lenses helps patients reduce their dependence on glasses or contacts most of the time. Medicare and most private insurance plans do not offer coverage for the advanced lens technology.

Your patient counselor can check on the specific benefits from your insurance provider.

NVISION Financing: Making Cataract Surgery Affordable for You

At NVISION, our goal is to make your procedure affordable and easy while helping you meet their vision goals. NVISION offers great financing options to make your procedure affordable for you, including up to 24-month, no-interest financing.

Your patient counselor will discuss the available financing options with you at your pre-procedure consultation.
