Does Cataract Surgery Cause Any Side Effects?

Cataract surgery is one of the safest and most routine procedures performed today. Modern technology, such as the use of the LenSx laser, has improved the accuracy and precision of parts of the surgical procedure and provides exceptional treatment outcomes.

Like any surgical procedure, there are potential side effects and complications of cataract surgery, even in the hands of a highly skilled, experienced and talented surgeon. Understanding what may occur after cataract surgery is important; it helps you keep an eye out for possible complications and alert your doctor if something goes awry.

During your pre-operative cataract surgery consultation, Mark Mandel, MD, will go over all of the surgical risks and side effects with you and answer all of your questions. Expect close follow-up after your procedure so he can monitor your eyes as they heal for any signs of complications.

What Are Punctal Plugs?

Usually the first line of defense against dry eye disease is to identify common lifestyle or environmental factors that could be contributing to symptoms, and then systematically eliminate those factors. If you see Bay Area ophthalmologist and cornea specialist Mark Mandel, MD, for dry eye symptoms, he may recommend that you modify or eliminate medications known to cause dry eye, up your intake of omega-3 fatty acids and add moisture to the air in your home with a humidifier. He may also recommend using artificial tears or medicated eyedrops to increase the moisture on the surface of your eyes.

If these measures do not control your symptoms, he may recommend an alternative treatment, such as the placement of punctal plugs, to make your eyes more comfortable.

Elevated Eye Pressure: Causes and Concerns

Ocular hypertension treatment in San Jose

Regularly checking your eye pressure is an important way you can help preserve your vision for a lifetime. Elevated eye pressure can occur without symptoms, and is as dangerous to your eyes as high blood pressure is to your organs. It is often the first sign that you may be developing glaucoma, a leading cause of blindness.

Below, experienced Bay Area ophthalmologist Mark Mandel, MD, discusses prevention and treatment strategies for this serious condition.

Elevated Danger

The cause of elevated eye pressure, known as ocular hypertension, is an imbalance in production and drainage of aqueous humor, the fluid inside your eye. Pressure builds as the eye creates new fluid and the channels which normally drain the aqueous humor become obstructed or damaged. Once that happens, internal pressure rises, and major damage to the optic nerve can result.

In many cases, there is no observable damage to the release channels, yet the natural system of drainage unexpectedly stops working. This system can also be disrupted by an injury to the eye (e.g., a sports injury or car accident) that damages those vital drainage channels, setting in motion the increase in pressure.

Additional Causes of Ocular Hypertension

You are at greater risk for developing ocular hypertension is you are over 40, have thin corneas or a family history of glaucoma. African Americans also have a statistically higher risk.

Use of steroids, including steroid eye drops that are sometimes prescribed after eye surgery, is also linked to elevated pressure within the eye. In addition, ocular hypertension may suddenly appear with the onset of other eye conditions, such as pseudoexfoliation syndrome, a condition related to age and genetics in which small protein fibers accumulate, clump together and block the free flow of fluid within the eye.

Pigment dispersion syndrome can similarly cause accumulation of drainage-blocking particles in the eye. When this condition occurs, granules of pigment break loose from the iris and obstruct one or more channels.

If you would like to know more about elevated eye pressure and ways to protect your vision, we encourage you to schedule a personal consultation with Bay Area ophthalmologist Mark Mandel, MD. Contact Optima Eye by emailing us or calling 877-210-2020 ext. 3 today.

How Permanent Are the Results of LASIK?

LASIK in San Jose

Clarity and convenience are among the top benefits of LASIK. In the minds of most consumers, convenience is measured in part by how long the improved vision will last. Fortunately, patients who have freed themselves from glasses or contacts do not have to subject themselves to a lifetime of vision correction surgeries. With LASIK, one procedure is all that is necessary in most cases.

Below, trusted Bay Area ophthalmologist and corneal specialist  Mark Mandel, MD, discusses how a life without lenses is within reach for the vast majority of adults.

Enduring Results

How permanent your LASIK results will be depends in part on your age, the stability of your prescription and your overall health. It is an urban myth that LASIK needs to be repeated every 10 years. However, the eyes continue to mature into your 20s, and so a LASIK procedure done at a very young age may be premature. Younger persons whose prescriptions need to be updated regularly should wait until their vision stabilizes for the best results.

Some patients who notice a slight regression at a later date may choose a LASIK enhancement procedure, which involves a minor reshaping of the cornea to correct for any vision changes. A recent study published in the American Journal of Ophthalmology followed patients whose LASIK corrected for extreme myopia. Within 10 years of the initial procedure, just 6 percent chose a LASIK enhancement to tweak their vision.

In the few cases in which nearsightedness, farsightedness or astigmatism eventually reappears after a LASIK procedure, it is unlikely you will ever return to your pre-surgical prescription. 

As we age, most of us will develop presbyopia, the farsightedness that tends to make reading more difficult. Even with LASIK, you may need to use reading glasses at this point in your life. For some patients over 40, a modified form of LASIK called monovision LASIK can be performed to correct presbyopia.

If you would like to know more about the benefits of LASIK, we encourage you to schedule a personal consultation with Bay Area ophthalmologist Mark Mandel, MD. Contact Optima Eye by emailing us or calling 877-210-2020 ext. 3 today.

Nutritional Optic Neuropathy Causes & Prevention

Eye health & nutrition in San Jose, CA

It’s not every day that a news story educates the public about the strong link between nutrition and ocular health. But it happened recently with the curious case of a British teen who survived for years on a diet centered on chips and crisps — or, as we like to call them in the U.S., French fries and Pringles. He rounded out his daily menu with white bread, sliced ham and sausages.

Bay Area ophthalmologist Mark Mandel, MD, believes this is the perfect cautionary tale for parents and kids alike. After a decade on this adolescent dream diet, the teen suffered substantial damage to his nervous system, including the optic nerve. He experienced partial hearing loss and nearly total loss of sight.

How Does Nutritional Optic Neuropathy Develop?


The clarity of your vision and health of your eyes are dependent on a variety of lifestyle habits. In the case of the teen, his levels of B12, vitamin D, copper, folic acid, magnesium and selenium had collapsed. This condition, known as nutritional optic neuropathy, is more often seen in places with famine, poverty and conflict, not in countries that deep-fry, process and wrap in paper their daily sustenance.

The last reported epidemic of nutritional optic neuropathy occurred in Cuba during the early 1990s, when a disintegrating economy limited healthy diet options for the general population.

Sometimes the condition develops when intestinal problems, changes resulting from bariatric surgery or the use of certain medications interfere with the proper absorption of nutrients. It can also happen when excessive alcohol consumption crowds out balanced meals, or even in the case of individuals who follow a very strict vegan diet.

Eye Nutrition, from A to B


From an early age most of us learn from our parents, or even a cartoon rabbit, that vitamin A is vital to eye health. B vitamins, along with iron and thiamine, are also essential. Thiamine deficiency can develop quickly, and impact eye movement and the optic nerve.

Non-starchy plant foods, such as fruits and leafy vegetables, are ideal sources of vitamin B. This eye-healthy vitamin can also be found in whole grains, eggs, dairy products, meat, nuts, seeds and legumes. Because many agronomists believe that overuse of farmland has resulted in depletion of nutrients in the soil and the produce grown there, daily vitamin supplements are also a good idea.

Bay Area ophthalmologist Mark Mandel, MD, reminds patients that nutrition plays a role in other aspects of eye health as well. Lack of nutrients can lead to early onset of cataracts or macular degeneration. And a poor diet has even wider health implications, as it correlates strongly with development of diabetes, heart disease, stroke and certain cancers.

If you would like to know more about ways to promote the health of your eyes, we encourage you to schedule a personal consultation with ophthalmologist Mark Mandel, MD. Contact Optima Eye by emailing us or calling 877-210-2020 ext. 3 today.

Healthy Aging Month: Tips for Eye Care Through the Years

Healthy Aging Month Eye Care Tips in San Jose

It is normal to notice changes in your vision as you get older. These may include loss of focus, having trouble distinguishing colors, and needing more time to adjust changing levels of light. Still, it is important to take precaution to minimize the risk of serious eye problems as you get older.

In honor of Healthy Aging Month, Bay Area ophthalmologist and cornea specialist Mark Mandel, MD, is here to share ways you can help preserve your vision and care for your eyes through the years.

Eat a Healthy, Eye-Friendly Diet

There is enough scientific evidence to suggest that consuming certain vitamins and minerals can minimize the risk of certain eye diseases, including cataracts and age-related macular degeneration. For good eye health, eat foods high in the following nutrients:

  • Vitamin C
  • Beta-carotene
  • Lutein
  • Zeaxanthin
  • Omega-3 fatty acids

Don’t Smoke

Smoking affects various aspects of your health, and your eyes are no exception. Research shows that smoking increases the risk of age-related macular degeneration, cataracts, glaucoma and other eye diseases.

Protect Your Eyes from the Sun

Protecting your eyes from the sun’s UV rays minimizes the risk of developing serious eye conditions, including cancer and cataracts. The best way to protect your eyes from the sun is to wear sunglasses that offer 100 percent UV protection. Because the sun’s rays can penetrate through clouds, it is essential you wear sunglasses year round, even during cold, overcast weather.

Manage Health Conditions

Health conditions such as hypertension and diabetes are linked to certain serious eye diseases, including cataracts. If you have a chronic condition, work with your primary care doctor to keep it under control. Take all medications as prescribed, see your primary doctor regularly and keep your eye doctor in the loop when it comes to your general health. You should also maintain a healthy weight, as being overweight increases the risk of diabetes and other chronic conditions connected to eye conditions.

Keep Up with All Eye Exams

Maintaining all of your regular eye exams is important, even if you are not experiencing any symptoms. This is because many eye diseases begin asymptomatic and can only be detected through an eye exam performed by an eye doctor. How often you should get your eyes examined depends on various factors, including your eye, current eye health and family history of eye diseases.

If you are experiencing any unusual eye symptoms, we encourage you to schedule a personal appointment with our ophthalmologist and cornea specialist Mark Mandel, MD. Contact Optima Eye by emailing us or calling 877-210-2020 ext. 3 today.
