Can a Nutritious Diet Prevent Age-Related Cataracts?

slice orange fruit and strawberries 1116558Age-related cataracts are extremely common — so common, in fact, that more than half of all adults develop cataracts in one or both eyes by age 65. Left untreated, cataracts can gradually cause vision loss, even blindness. You can take steps to prevent this. By consuming foods or supplements rich in antioxidants, you may be able to slow the development and progression of cataracts.

What are Cataracts?

Cataracts refer to the clouding of the eye’s natural lens due to light passing through to the retina in a scattered, rather than focused, manner. This leads to changes in vision, resulting in blurry vision and faded colors. This also impacts one’s ability to clearly see at night.

Cataracts come in three forms: nuclear, cortical, and posterior capsular, each of which depends on their locations on the lens.

Age-related cataracts are caused by tissue breakdown and protein clumping on the lens. Exactly why this happens isn’t yet clear. Cataracts must be taken seriously. Unaddressed, they can lead to vision loss or even blindness.

Once a cataract has developed, there is no cure except to have it surgically removed

How Are Cataracts Diagnosed?

To diagnose cataracts, an optometrist will assess the patient’s visual acuity, color vision, and evaluate their sensitivity to bright light. will also examine the front of the eye using a microscope, called a slit lamp, and check the retina for signs of cataracts.

Once cataracts have been diagnosed, the condition must be carefully monitored with regular eye exams. Because vision deteriorates over time, eyeglass or contact lens’ prescriptions will need to be frequently adjusted.

It is strongly advised to regularly wear sunglasses and wide-brimmed hats to avoid the harmful effects of ultraviolet rays on the eyes. Furthermore, since cataracts cause poor night vision, with halos around street lights and car headlights, people with cataracts may need to stop driving at night.

Once the condition has reached an advanced stage, the cataract will have to be surgically removed and replaced with a synthetic intraocular lens (IOL).

Diet and Nutritional Supplements Can Help Against Cataracts

Research suggests that antioxidants play an important role in staving off cataracts. In one study of 30,000 women aged 49 and older, those who consumed the most antioxidants had a 13% lower risk of developing cataracts than the group of women who consumed the least.

Certain foods and supplements rich in antioxidants may protect against free radicals — unstable atoms that cause cellular damage — that attack the lenses of the eyes and contribute to the formation of cataracts. Four powerful nutrients, Vitamin C, Vitamin E, lutein and zeaxanthin, can delay the onset and even decrease the risk of developing cataracts.

Foods containing these nutrients include:

Lutein and zeaxanthin

Kale, spinach, egg yolks, salmon and certain yellow and orange vegetables, such as cantaloupes, corn, carrots and peppers

Vitamin C

Apples, bananas, grapefruit, oranges, peaches, spinach, tomatoes

Vitamin E

Nuts: hazelnuts, almonds, peanuts (including peanut butter)

Seeds: sunflower seeds

Oils: soybean, canola, corn, sunflower, safflower, wheat germ

Green leafy vegetables: spinach, broccoli

Fruit: kiwi, mangos, tomatoes

Vitamin-fortified cereals

To preserve eye health and reduce the risk of cataracts, you’ll want to avoid processed, fried and junk foods.

Can You Undergo Cataract Surgery and LASIK Surgery?

Happy Middle Aged CoupleHave you had LASIK surgery as a young adult and are now wondering whether it may compromise your eligibility for cataract surgery later in life? You can put your mind to rest; it is indeed possible for someone to undergo both LASIK and cataract surgery — though only in that order. Someone who’s had LASIK can have cataract surgery later in life, but someone who’s had cataract surgery, in most cases, is no longer a candidate for LASIK or other refractive surgeries.

If you have any questions about your eligibility for either surgery or regarding any other ocular health matter, call for all of your eye care needs.

Understanding LASIK Surgery and Cataract Surgery

To better understand why cataract surgery is possible following LASIK surgery, it’s important to know the basics of both procedures.

LASIK surgery and other refractive surgeries are performed on the cornea — the dome-shaped, clear tissue at the front of the eye. During LASIK surgery, a laser reshapes the cornea so it refracts, or bends, light waves more precisely onto your retina (the light-sensitive tissue lining the back inner portion of the eyeball), resulting in clearer vision.

Cataract surgery, however, is performed on the eye’s natural lens — which is positioned just behind the iris (the colored part of the eye). The lens is responsible for focusing the light that passes through the eye onto the retina to produce a clear, crisp image. A healthy lens should be transparent and clear. Those with cataracts experience a clouding of the lens which disturbs normal vision. During cataract surgery, the cloudy natural lens is removed and replaced with a synthetic lens, improving the clarity of your vision.

Cataract Surgery Without Having Had LASIK

The artificial replacement lens is designed to correct vision and replace prescription glasses. For those who have not had refractive surgery, vision correction through cataract surgery is usually uncomplicated and has a predictable outcome. After cataract surgery, many patients experience clear distance vision without the need for spectacles, although many will still need their reading glasses.

Cataract Surgery Following LASIK Surgery

The modern equipment used by takes very accurate measurements of the eyes, even many years after having undergone LASIK surgery. However, it is still highly recommended for those who have had LASIK surgery to provide the surgeon with all previous eye health records so that the appropriate lens implant be used for cataract surgery. If you do not already have them, you can request these records from the doctor who performed your LASIK surgery. If obtaining these records is not possible, cataract surgery can still be an option, though the postoperative refractive error may not be as predictable.

Does Glaucoma Prevent Cataract Surgery?

Lively Older Man Riding His Bicycle, Laughs And Enjoys Life. SenFor those with clouded or hazy vision, cataract surgery can work wonders in restoring crisp and clear vision. However, if you’ve been diagnosed with glaucoma, you might be wondering whether cataract surgery is a safe option. Below, we’ll discuss glaucoma and explain why it doesn’t prevent cataract surgery.

What Is Glaucoma?

Glaucoma refers to a group of eye diseases where the loss of vision is due to optic nerve damage due to a buildup of pressure inside your eye. This condition generally displays no early warning signs, and can only be detected with a comprehensive eye exam. If not treated early, glaucoma will first lead to peripheral vision loss and ultimately permanent central vision loss.

Glaucoma, like cataracts, affects mostly the elderly. Therefore, many patients with glaucoma over the age of 50 or 60 may also be concerned with developing cataracts.

How Does Glaucoma Affect Cataract Surgery?

In short, it doesn’t.

In fact, cataract surgery may (at times) even lower high intraocular pressure, making it a great option for those with glaucoma.

Furthermore, it may be possible for the eye surgeon to perform a minimally-invasive glaucoma surgery during cataract surgery.

If a patient with glaucoma undergoes cataract surgery, it is vital to closely adhere to the post-surgical instructions for optimal safety. Internal eye pressure can rise during or in the hours following cataract surgery.
