is now the Internet age. People work in front of computer screens for a long time every day, but this also brings great eye health problems. According to the 2020 edition of the "China Dry Eye Expert Consensus", the proportion of people suffering from dry eye in my country is as high as 21% to 30%. It is roughly estimated that there are about 360 million people suffering from dry eye in my country.

It should be clear that some friends have dry eyes, pain, soreness and discomfort, blurred vision, etc. may be short-term visual fatigue, not necessarily dry eye disease. Vision fatigue can be quickly alleviated through moderate rest or short-term medication improvement, while the problem of dry eye disease requires long-term intervention.

What is dry eye disease? 8 types of eye drops that improve dry eyes may improve eye discomfort

Dry eye disease, also known as keratoconjunctival serpentine, refers to various diseases that cause abnormal quality, amount or kinetic abnormality of tears caused by any cause, resulting in decreased tear film stability, accompanied by eye discomfort, and eye surface tissue lesions. Common symptoms are dry eyes and foreign body sensation or blurred vision, easy fatigue, burning sensation, itching, congestion, photophobia, pain, sticky filamentous secretions, etc.

The eyes of patients with more severe symptoms will be red, swollen, congested, keratinized, . The corneal epithelium breaks the skin and has filaments adhered. If the damage is long, it can cause keratoconjunctival lesions and cause vision loss. Dry eye disease is a chronic disease and requires long-term treatment. You should reduce the use of computers, contact with air conditioners, and remove smoke and dust. For those with meibomian gland dysfunction, pay attention to cleaning the eyelids, applying antibiotics to artificial tears, and wear wet aid glasses, silicone eye masks, etc. to prolong the time the tears stay on the eye surface.

After dry eyes develop, common early symptoms are dry eyes, red eyes, photophobia and other symptoms:

. Dry eyes: mainly due to the reduction of tears, dry eyes after using the eyes, fatigue of vision.

. Red eyes: Symptoms of red eyes will appear after using the eyes.

. Foreign object sensation: It feels like there are sandy foreign objects in the eyes, and there is a feeling of friction, and the eyes are painful.

4. Photophobia: Symptoms such as photophobia and tears appear.

5. Other symptoms: blurred vision, and symptoms such as glasses falling off when wearing contact lenses.

8 types of eye drops to improve dry eyes may improve eye discomfort

. Artificial tears: The main function of artificial tears is to lubricate the eye surface. Artificial tears are the most commonly used type of drug in the field of dry eyes treatment. By replenishing moisture and lubricing the eye surface, this type of drug can enhance the stability of the tear film, prolong the application time of the tear film, prevent tears from evaporating, and effectively improve the symptoms of dry and discomfort in the eyes.

At present, the most commonly used artificial tears is sodium hyaluronic acid eye drops, which are generally available in two specifications: 0.1% and 0.3%, respectively, for the improvement of mild and moderate-severe dry eyes. In addition, hydroxymethylcellulose eye drops, polyethylene glycol eye drops, and polyacrylic eye drops are also commonly used drugs.

. Eye drops that promote tear secretion: One of the reasons for dry eyes is that the tear film is unstable and the tears are insufficient. This type of drug can stimulate tear secretion and has a certain stimulating effect on lipid secretion. It is a commonly used drug to improve dry eyes.

Clinically, the most common drug is dequafsolana eye drops. This drug enhances tear secretion and improves dry eyes by promoting mucin secretion. In addition, there are drugs such as Rebapt, which can be used for mucin abnormalities and mixed dry eyes.

. Eye drops that promote eye surface repair: Generally, for patients with moderate and severe dry eyes and accompanied by obvious corneal epithelial injury, artificial tears can be used while using eye drops that promote eye surface repair. This type of eye drops generally use fibroblast growth factor, erotic growth factor, vitamin A and other main components, which have the effect of promoting epithelial hyperplasia and protecting eye surface microcirculation.

4. Eye serum preparation: In order to promote epithelial repair of the surface of the eye and improve the microcirculation of the eye surface, patients with dry eye syndrome accompanied by epithelial damage and corneal neuralgia may consider using autologous serum or calf serum protein extracted ophthalmic preparations to improve the problem of moderate and severe dry eyes. The biologically active ingredients contained in this type of preparation can promote repair of damaged epithelial.

5. Glucocorticoid drugs: Glucocorticoid drugs anti-inflammatory have significant effects. For inflammation of dry eye problems, eye drops using glucocorticoid drugs, such as flumelon eye drops, containing dexamethasone , loteprenol, cortisone and other eye drops, all belong to this type of drug. This drug is generally not used as a long-term maintenance drug, and is mainly used for moderate and severe dry eye diseases.

6. Immune preparation drugs: For patients with moderate and severe dry eyes with ophthalmic inflammation, immune preparation drugs are also the first type of drug to improve inflammation. Common drugs include tacrolimus eye drops, cyclosporine A eye drops, etc. The frequency of use of this type of drug is generally no more than twice. Cyclosporine can choose low-dose long-term medication, while tacrolimus is suitable for impact treatment of severe patients.

7. Nonsteroidal anti-inflammatory drugs: The anti-inflammatory effect of nonsteroidal anti-inflammatory drugs is lower than that of glucocorticoid drugs, but is relatively safer. For anti-inflammatory treatment of mild and moderate dry eyes and the treatment of moderate to severe hepatitis maintenance period, patients with high-risk hepatitis who are intolerable to glucocorticoids can choose nonsteroidal anti-inflammatory eye drops, common ones include praprofen eye drops, bromofenac sodium eye drops, etc.

8. Antibiotic drugs: This type of drug generally has anti-inflammatory effects and has certain anti-inflammatory effects. It is generally used in patients with dry eye diseases with abnormal eyelid margins. It can also be used to maintain the use of glucocorticoid after stopping the use of . Common quality include tetracycline eye drops, azithromycin eye drops, fusidic acid eye drops, etc.

Will frequent eye drops cause dependencies?

eye drops cannot be used frequently. Most eye drops with eye protection function are composed of artificial tears and cellulose and some vitamins. Some will also add nutrients, bactericidal and anti-inflammatory ingredients and some preservatives. This will not only cause drug dependence, self-cleaning of the eyes, and decrease function, but will also cause damage to cornea and conjunctiva .

Eye drops containing antibacterial ingredients may cause the bacteria in the eye to develop resistance to drugs. Once the eyes are infected, treatment will be difficult. If there is inflammation, it may also cause mild corneal inflammation, because the right medicine cannot be prescribed, causing corneal ulcers. The most serious thing is to stabilize the performance of the drug and not be contaminated by external microorganisms for a long time.

Most eye drops contain preservatives. These ingredients can change the microenvironment of the eyeball surface, destroy the structure of the eye surface, damage the structure of the originally closely connected epithelial cells, cause corneal epithelium to fall off, defects and erosion, and in severe cases, corneal ulcers, corneal dissolution and perforation, and blindness.
