Eye vitamins during cataract

Eye vitamins during cataracts: complex guide

What is cataracts and how does it affect vision?

Cataract is a clouding of the lens of the eye, a transparent lens located behind the rainbow shell. Normally, the lens passes the light on the retina, allowing us to see clearly. In cataract, the lens gradually loses its transparency, which leads to scattering of light and impairment of vision.

The process of cataract formation is usually slow and painless. At first, a slight clouding of vision, difficulty in reading, especially in poor lighting, increased sensitivity to bright light, double -skinned double (rarely), and changes in the perception of flowers can be observed. As cataract progresses, vision becomes more and more blurry and fuzzy, which can significantly complicate everyday activity, such as driving a car, reading and watching a TV.

There are various types of cataracts that are classified depending on the place of their formation in the lens:

• Nuclear cataracts: It begins in the center of the lens (nucleus) and gradually spreads to the periphery. This type of cataracts often leads to a deterioration in vision, but sometimes it can improve vision near the early stages, the effect known as the “second vision”.
• Cortical cataracts: It begins in the bark of the lens, the outer part surrounding the core. This type of cataract is often characterized by wedge -shaped cloudings that spread from the periphery to the center. Cortical cataracts can cause glare and halo around light sources.
• Rear sucapsular cataracts: It develops on the back surface of the lens, under the capsule holding the lens in place. This type of cataracts often progresses faster than other types, and can cause significant visual impairment, especially when reading and in bright light.
• Congenital cataracts: Present at birth or develops during the first months of life. Congenital cataracts can be caused by genetic factors, infections during pregnancy (for example, rubella) or other medical conditions.

Risk factors for cataract development include:

• Age: The risk of cataracts increases with age. Most people begin to notice signs of cataracts after 60 years.
• The effect of ultraviolet (UV) radiation: The long-term exposure to UV radiation from sunlight increases the risk of cataracts.
• Smoking: Smoking is associated with an increased risk of cataract development.
• Diabetes: People with diabetes have an increased risk of cataracts.
• Family history of cataracts: The presence of cataracts in close relatives increases the risk of its development.
• Eye injury: Eye injury can lead to cataract development.
• Some drugs: Long -term use of corticosteroids can increase the risk of cataracts.
• Previous operation in the eyes: Operation in the eyes, such as vitrectomy, can increase the risk of cataracts.
• Obesity: Studies show the relationship between obesity and an increased risk of cataract development.
• High blood pressure: High blood pressure can also be a risk factor.

The role of vitamins and nutrients in maintaining the health of the eyes

Eye health depends on the sufficient receipt of certain vitamins and nutrients. These substances act as antioxidants, protect the eyes from damage caused by free radicals, and support the normal functioning of visual cells. Although vitamins cannot cure existing cataracts, they can help slow down its progression and maintain the general health of the eyes.

• Vitamin C (ascorbic acid): A powerful antioxidant that helps protect the lens of the eye from oxidative damage caused by free radicals. Studies show that higher consumption of vitamin C is associated with a lower risk of cataract development. Vitamin C also promotes the formation of collagen, an important protein for the structure of the eye. Good sources of vitamin C: citrus fruits (oranges, lemons, grapefruits), berries (strawberries, blueberries, cranberries), kiwi, bell pepper, broccoli, Brussels cabbage.

• Vitamin E (Tokoferol): Another powerful antioxidant that protects cell membranes from damage caused by free radicals. Vitamin E works synergically with vitamin C, enhancing its antioxidant properties. Studies show that vitamin E can help slow down the progression of cataracts. Good sources of vitamin E: vegetable oils (sunflower, safflower, olive), nuts (almonds, hazelnuts, walnuts), seeds (sunflower, pumpkin), avocado, green leafy vegetables (spinach).

• Lutein and Zeaxanthin: These carotenoids are powerful antioxidants, which are concentrated in the makul, the central part of the retina, responsible for acute vision. Luthein and Zeaksantin protect the macula from damage caused by blue light and free radicals. Studies show that higher consumption of lutein and zeaxanthin is associated with a lower risk of cataract development and age macular degeneration (VMD). Good sources of lutein and zeaxanthin: dark green leafy vegetables (spinach, cabbage, manhold), broccoli, corn, egg yolk.

• Zinc: An important trace element that plays the role in the metabolism of vitamin A and in the antioxidant protection of the eyes. Zinc helps to maintain the health of the retina and lens. Zinc deficiency can increase the risk of cataracts. Good sources of zinc: oysters, red meat, poultry, legumes, nuts, whole grain products.

• Selenium: An antioxidant mineral that works with vitamin E to protect cells from damage caused by free radicals. Selenium can help slow down the progression of cataracts. Good sources of selenium: Brazilian nuts, seafood (tuna, salmon, shrimp), meat, poultry, eggs, whole grain products.

• Omega-3 fatty acids: These fatty acids, especially the DHC (daily acidic acid), are important for the health of the retina and maintaining eye humidity. Omega-3 fatty acids can help reduce inflammation and protect the eyes from damage caused by free radicals. Studies show that the higher consumption of omega-3 fatty acids is associated with a lower risk of cataract development. Good sources of omega-3 fatty acids: fatty fish (salmon, tuna, sardines, macrel), linseed seed, chia seeds, walnuts.

Vitamin complexes for the eyes with cataracts: what to look for?

On the market there are many vitamin complexes designed to maintain the health of the eyes and slow down the progression of cataracts. When choosing a vitamin complex, it is important to consider the following factors:

• Composition: Make sure that the complex contains the necessary vitamins and nutrients, such as vitamin C, vitamin E, lutein, zeaxantin, zinc, selenium and omega-3 fatty acids.
• Dosage: Consult a doctor or pharmacist to determine the optimal dosage of vitamins and nutrients that meets your individual needs. It is important to observe the recommended dosages and avoid excess, since some vitamins in high doses can be harmful.
• Quality: Choose vitamin complexes from reliable manufacturers who adhere to strict quality standards. Pay attention to the availability of quality certificates (for example, GMP).
• Output form: Vitamin complexes are available in various forms, such as tablets, capsules, chewing tablets and drops. Choose a form that is most convenient for you.
• Individual needs: Consider your individual needs and health status when choosing a vitamin complex. If you have any diseases or take any medicine, consult a doctor before starting to take a vitamin complex.

Some popular eye vitamin complexes containing ingredients that are useful for cataract include:

• Arreds 2 Formula: Developed by the National Institute of Eye (Nei) as part of the study by Age-RELEETED EYE Disease Study 2 (AREDS2). This formula contains vitamin C, vitamin E, lutein, zeaxantin and zinc. AREDS2 The formula showed its effectiveness in slowing the progression of age -related macular degeneration (EMD) and can also have a positive effect on the progression of cataracts.
• Ocuvite: Contains vitamin C, vitamin E, zinc, lutein and zeaxantin.
• PreserVision: Contains vitamin C, vitamin E, zinc, lutein and zeaxantin.
• MacuGuard: Contains Luthein, Zeaxantin, Meso-Zaacsantin and alpha-lipoic acid.

It is important to remember that vitamin complexes are only an addition to a healthy lifestyle and a balanced diet. They cannot replace the surgical treatment of cataracts.

Eye nutrition: products that are useful for cataracts

A balanced diet, rich in vitamins, minerals and antioxidants, plays an important role in maintaining the health of the eyes and slowing down the progression of cataracts. Include the following products in your diet:

• Fruits and vegetables: Use a variety of fruits and vegetables of bright colors, such as citrus fruits, berries, dark green leafy vegetables, bell pepper, carrots and broccoli. These products are rich in vitamins C and E, lutein, zeaxantin and other antioxidants.
• Fish: Include oily fish in your diet, such as salmon, tuna, sardines and macrel, 2-3 times a week. These products are an excellent source of omega-3 fatty acids.
• Nuts and seeds: Use nuts and seeds such as almonds, hazelnuts, walnuts, sunflower seeds and chia seeds. They are rich in vitamin E, zinc, selenium and omega-3 fatty acids.
• Eggs: Egg yolk is a good source of lutein and zeaxantin.
• Whole grain products: Include whole grain products in your diet, such as oatmeal, brown rice and whole grain bread. They are rich in zinc and other nutrients.
• Water: Drink enough water to maintain hydration of the body and eye health.

Avoid or limit the consumption of the following products:

• Processed products: Producted products often contain a lot of sugar, salt and saturated fats, which can negatively affect the health of the eyes.
• Sweet drinks: Sweet drinks, such as carbonated drinks and fruit juices, contain a lot of sugar, which can increase the risk of diabetes and other diseases associated with cataracts.
• Transjir’s: Transfiders are contained in fried products and some processed products. They can increase the risk of developing cardiovascular diseases and other health problems that can negatively affect the health of the eyes.
• Alcohol: Excessive alcohol consumption can increase the risk of cataracts.

Other factors affecting eye health during cataracts

In addition to vitamins and nutrition, other factors can also affect the health of the eyes and progression of cataracts:

• UV protection protection: Wear sunglasses that block 100% UV-A and UV radiation to protect your eyes from the harmful effects of sunlight.
• Regular examinations by an ophthalmologist: Regularly visit an ophthalmologist to check vision and identify signs of cataracts or other eyes.
• Blood sugar control: If you have diabetes, carefully control the blood sugar level to reduce the risk of cataracts.
• Refusal of smoking: Smoking is associated with an increased risk of cataracts and other eye diseases.
• Healthy lifestyle: Maintain healthy weight, regularly engage in physical exercises and avoid stress.

Surgical treatment of cataracts

Although vitamins and healthy nutrition can help slow down the progression of cataracts, surgical treatment is the only effective way to remove cataracts and restore vision. During the operation, the surgeon removes a clouded lens and replaces it with an artificial lens (intracular lens or iola). The operation to remove cataracts is one of the most common and safe surgical procedures in the world.

There are various methods of surgical treatment of cataracts:

• Focemulsification: The most common method in which the surgeon uses ultrasound to destroy a clouded lens into small fragments, which are then removed from the eye by suction. Then Iol is inserted.
• Extracapsular cataract extraction: A method in which the surgeon removes the lens entirely through a larger incision. This method is used less often than phacoemulsification, and can be recommended in cases where cataract is very dense or in the presence of other complications.
• Femtosecond laser cataract surgery: This method uses a femtosecond laser to perform some stages of surgery, such as a cornea section, capsulotomy and fragmentation of the lens. Femtosecond laser surgery can provide greater accuracy and predictability, but it is also more expensive than other methods.

After the operation to remove cataracts, most people note a significant improvement in vision. Vitamins and healthy diet can help support the eye of the eyes after surgery and reduce the risk of other eyes of the eyes.
