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.

There are 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.

Patients with cataracts may notice one or more of the following symptoms:

  • a painless decrease in vision
  • light sensitivity or glare
  • decreased vision in sunlight
  • decreased vision from oncoming headlights
  • frequent eyeglass prescription changes
  • double vision in one eye
  • needing brighter light to read
  • poor night vision with glare
  • halos, or starbursts
  • fading or yellowing of colors

How Is a Cataract Treated?

How to Treat Cataracts in San Jose Surgery 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 ultrasound waves through a small incision to remove your cataract.

Discover How Custom Cataract Surgery Can Help You Get Back to the Life You Once Enjoyed

 The focusing power of your eye is restored by replacing the cataract with a permanent intraocular lens implant (IOL). 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. (Read about lens options in the following section.) 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.

ORA – Optiwave Refractive Analysis

After the cloudy lens (cataract) has been removed, you can elect to have an additional confirmatory measurement with a real-time wavefront analyzer to assess and refine the exact measurements of the eye to ensure the most accurate lens implant power. This helps us to hit the target implant power more accurately without the cataract impeding the measurement. This leads to a better opportunity to refine and customize the implant power to your individual eye.

It’s Here … 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.

Benefits of LenSx Laser Technology

Bay Area LenSx technology for cataracts

  • Faster recovery time


Cost of Cataract Surgery

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 (multifocal, toric) or for the LenSx laser procedure or ORA procedures.

Cataract Lens Implant Choices

  1. Both eyes adjusted for distance vision

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.

  1. One eye adjusted for distance and the other eye adjusted for near (blended or monovision)

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, if the patient has astigmatism, we can use the Toric implant. With blended or monovision, patients can be glasses free much of time.

  1. For patients with high amounts of astigmatism (Toric Implant)

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 incorporated 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.

  1. Multifocal implants

For many years, we have been using multifocal implant lenses. Dr. Mandel was one of the first surgeons in Northern California to implant the multifocal lens. These “premium” lenses are the highest technology lenses available. With this option, each eye receives a multifocal lens. When looking at a distant object, patients can see well in the distance. Also, patients can see well when viewing intermediate targets such as the dashboard, a cell phone, a computer, or a wrist-watch. Often, near targets such as menus and the newspaper can also be seen more clearly than with the standard lens implant. By far, this is the best option for patients who wish to have as “natural” vision as possible at all distances. We use the PanOptix, Vivity and the Symfony multifocal lenses. Although we strive for glasses-free vision, these lenses and the healing of the human eye are never perfect and occasionally the use of glasses or corrective surgery may be necessary to “fine tune” the vision for certain distances following the implantation of a multifocal implant.

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 eyedrops 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.


Cataracts are a common cause of poor vision, but they are treatable. Our experienced surgeons can tell you whether a cataract or some other problem is the cause for vision loss, and help you decide if cataract surgery is appropriate for you. Additionally, we will help you choose the lens implant that best suits your lifestyle. If you elect to undergo surgery, you have an extremely high chance of experiencing greatly improved vision.

“Recently, I had cataract surgery…a painless, brilliant procedure that left me with razor sharp vision. Of course, I thank my surgeon, Dr. Mark Mandel. And, I should mention, this is the third time I am thanking him!” – Jann Yanehiro, cataract surgery patient

Brian Elliott, O.D.
Optometrist (Modesto)

“As an optometrist, I appreciate the value of precise vision and am aware of the risks of cataract surgery. When I needed cataract surgery, I chose Dr. Mandel to perform my procedure. I now routinely share my story with my patients in need of surgery and can attest to Dr. Mandel’s exceptional expertise based on my own personal experience and great outcome.”

Lee K Schwartz, MD
Professor of Ophthalmology
CPMC San Francisco

Having finally reached that point in life where I wanted to have cataract surgery, I thought long and hard about who the surgeon would be. I had LASIK surgery in 2002 because of extreme nearsightedness.

As a practicing eye surgeon in San Francisco, I know all of the eye surgeons in the Bay Area. I initially thought of the convenience of having it done near my home. However, having known Dr. Mark Mandel for the past 30 years I realized it was worth the trip to see him at his Hayward office.

As an eye surgeon who has had advanced fellowship training in corneal and cataract surgery I of course felt very comfortable having the procedure. But I knew that the post-operative outcome could be tricky following a prior LASIK procedure.

As I was one of Dr. Mandel’s professors during his residency, I knew of his love and respect for the profession, his meticulous surgical technique and ability to personalize the surgical result.

So here I am three years later, continuing to practice ophthalmology and perform eye surgery. I also continue to teach the next generation of young eye surgeons and to mountain bike, drive to work and read medium size print without glasses. I will still use readers for extended reading and at times when needed in my practice. But most of the day I go without glasses.

I am most grateful for Dr. Mandel’s kindness, his skill, and my wonderful surgical outcome. Thank you!
