What is a cataract?

A cataract is a clouding or opacification of the naturally clear lens inside the eye. This clouding causes blurred or foggy vision or glare. It is not a visible film or growth over the outside of the eye. The word “cataract” actually means “waterfall” – as if one were looking through a waterfall.

Two basic types of cataracts

The slower growing “nuclear” type in which the entire lens turns yellow-brown, and the faster growing “subcapsular” type which affects younger people, those with diabetes, and patients taking cortisone.

How do I know if I have a cataract?

Cataract Surgeon in San Jose & Bay AreaYou will probably notice a decrease in vision and/or glare and halos around lights. You may be unable to see clearly to perform the tasks that you need or want to do. Changes in your eyeglass prescription will no longer improve your vision.

A thorough eye examination by your optometrist and our surgeons can detect the presence of a cataract, as well as other conditions that also may be causing altered vision.

Other reasons for visual loss in addition to the cataract may involve problems with the cornea, the retina, the blood vessels in the back of the eye, or the optic nerve. If these other conditions are present in addition to the cataract, you will likely experience an improvement in vision, but not perfect vision following cataract surgery.

We will explain to you and your family the details of your situation after a thorough exam.

How is a cataract treated?

How to Treat Cataracts in San JoseSurgery is the only way that a cataract can be treated. There are no pills or drops, vitamins, exercises, or lenses that have been shown to prevent or cure cataracts. However, if symptoms from a cataract are mild, a change of glasses may be all that is necessary for you to function more comfortably as the cataract progresses.

Protection from excessive sunlight may help prevent or slow the progression of cataracts. Sunglasses that screen out ultraviolet (UV) light rays or regular eyeglasses with a clear, anti-UV coating offer this protection.

If surgery is required, it is comforting to know that cataract surgery is safe and extremely effective in restoring vision. In fact, cataract surgery has one of the highest success rates of any surgery.

About 2 million people a year have cataract surgery in the United States. Our surgeons are among the most experienced in the country.

What can I expect from surgery?

At OPTIMA, cataract surgery is performed under local anesthesia at our federally-certified ambulatory surgery center located within our office. Our center was the first outpatient surgery center in the United States to be certified by Medicare and has been in continuous operation since 1981. Because our center specializes only in eye surgery, our highly trained staff is dedicated to ensuring the highest level of care. We use only state-of-the-art equipment in our warm and comfortable environment.

Before surgery

Before surgery we communicate with and obtain medical clearance from your primary care physician. During surgery you will be awake, but relaxed. Our anesthesiologist will be at your side.

We perform this intricate surgery using a microscope, micro-surgical instruments, and, if the patient chooses, the LenSx femtosecond laser. We were the first site in California to utilize the Alcon Centurion Cataract System which employs the latest technology using radar waves through a small incision to remove your cataract.

The focusing power of your eye is restored by replacing the cataract with a permanent intraocular lens implant. We often use multifocal implants that allow both distance and near, or distance and intermediate vision if the patient desires. If one has astigmatism, we can use an astigmatism (toric) implant and/or the LenSx laser to decrease the astigmatism. In most cases, sutures are not needed.

Due to advances in medical technology, we now have a number of choices for the type of advanced lens implants which will be placed in the eye. The physicians and staff at OPTIMA are here to help you make the choice, but ultimately, the choice of which implant to use is up to the patient and the family.

Laser-Assisted Cataract Surgery

Until now, standard cataract procedures were performed manually where the surgeon used a blade for all of the incisions and other portions of the procedure. A manual procedure allows for a margin of error that can affect outcomes. Recent innovations have led to the development of laser-assisted cataract surgery. The LenSx femtosecond cataract laser offers the precision of bladeless laser technology allowing the doctors at Optima to plan, customize, and perform your surgery to exacting, individualized specifications. Laser-assisted cataract surgery combined with advanced lens implant options are providing our patients with an improved lifestyle with more freedom using the latest technology.

Cataract Lens Implant Choices

Lenses for distance vision adjusted to Both eyes

If the power of the intraocular lens for both eyes is adjusted for distance vision, patients generally will need glasses for some distance functions as well as for reading and intermediate tasks such as the computer, dashboard, cell phone, and wristwatch. With this option, glasses will be required most of the time at most distances.

One eye lens adjusted for distance and the other eye adjusted for near (blended vision)

By using different implant powers for each eye, we can adjust the vision in one eye for the distance and in the other eye for near tasks such as reading. For this option, we use either the Staar Nanoflex lens, or if the patient has astigmatism, the Alcon Toric implant. With blended vision, patients can be glasses-free much of time.

Toric Lens for patients with high amounts of astigmatism

Astigmatism is when the eye is shaped more like a football than a basketball.  There is a lens implant option called the “toric” IOL.  This lens has the astigmatism ground into the implant (like your glasses).  The advantage to this lens upgrade is that, because it significantly reduces or eliminates the astigmatism, people are often glasses-free or much less dependent upon glasses following surgery for the distance.  However, unless we do monovision or blended vision with the toric lens, glasses will be required for computer and reading.

MULTIFOCAL / BIFOCAL: Panoptix, Symfony,Tecnis

This is the highest technology option for vision correction. The Panotix, Symfony and the Tecnis lenses offer the greatest opportunity for cataract patients to potentially live free from glasses. These lenses are designed to correct vision for near, intermediate and far distances. Although most patients are glasses-free most of the time, it is still possible that some patients will need glasses for some tasks some of the time. This lens is not covered by insurance.

Cataract Implant Lens Choices

After your surgery

After cataract surgery, you may return almost immediately to all but the most strenuous activities. We will provide you with written instructions and a helpful guide for the use of eye drops following your surgery. Several post-operative visits are needed to check on the progress of the eye as it heals.

Cataract surgery is a highly successful procedure. However, it is important to understand that complications can occur during or after the surgery, some severe enough to limit or lose vision. Fortunately, in our hands, improved vision is the result in over 99% of cases unless there is a pre-existing problem with the cornea, retina, or optic nerve. In approximately 15% of people having cataract surgery, the natural capsule that supports the intraocular lens will become cloudy within 6 to 24 months following surgery. In these cases when part of the cataract “grows back,” the YAG laser is used to painlessly open this cloudy capsule, restoring the clear vision. This is performed as an outpatient procedure at our office.

Cataract Surgery Cost

Medicare and insurance companies pay for the removal of the cataract and the standard distance implant. However, they do not pay for the upgrade for the premium implants or for the LenSx laser procedure.
