Background: In August 2009, CCTV’s “Road to Health” did a popular science program on “how to correctly order eye drops”, and saw many patients on the Internet are very concerned about the way to order eye drops, specially find the interview transcript at the time, sent here, hoping to give the majority of users a little help. Interview transcript: 1, Q: We just noticed a problem in the video, now we find that the people who order eye drops really special, you have eye drops, I use a little, how do the two experts see this phenomenon of using eye drops at will? A: According to our own statistics, as well as relevant statistics, the phenomenon of their own eye drops can reach about 70%, very much in the white-collar level, why this reason, mainly because many people think that eye drops must not have side effects, which is a small matter, a little bit of what problems can arise, the second is that the eyes do not feel well, want to point, there is another situation is that the eyes do not feel well, he wants to increase the number of drops. Comfortable, he wants to increase the number of eye drops to improve the effectiveness of the main phenomenon is this. 2.Q: Why do people order eye drops at will like this? A: I think there are several reasons for this, first of all, many office workers they are relatively busy, to the hospital when they feel difficult to seek medical treatment, the second we sell a lot of OTC eye drops in pharmacies, that is, over-the-counter drugs, so they get very easy, the third I think with the popularity of our advertising or more related, for example, many of our eye drops star a little after the sales are more, which led to There are also some of our more common use of eye drops is post-menopausal women, their hormone levels have dropped after menopause, which can cause a lot of physical discomfort, including eye discomfort, so they also need to use a little. 3, Q: Next we would like to talk to you about, if you randomly point eye drops, what kind of harm will cause? A: I think there are two main aspects, one is the short-term, if you point eye drops, some patients point eye drops itself is not the right symptoms, and even the method of medication, the effect is the opposite, for example, there is a drug is a pupil-dilating drugs, the treatment of myopia, if he ordered the pupil-shrinking drugs, may produce a certain amount of harm, the other is also some of their own drugs cause allergies, if long-term, frequent long-term point In fact, in our clinical work, it is true that one drop of eye drops can lead to blindness, for example, some patients have acute glaucoma, but they use eye drops for some reason. For example, some patients have an acute glaucoma base, but due to some circumstances, they use pupil-dilating drugs, which may lead to an acute attack of glaucoma, and if the resuscitation is not timely, the eye may cause blindness. Any drug has its effectiveness and side effects, so if you do not respect the medical advice, it can be an accident, there is another more extreme thing, when we go out to the emergency room, there are often people pointing foot water to the eyes, he belongs to the wrong medicine, he put several drugs next to him, he just have a bottle and point to the eyes, so then we deal with it is more difficult, because The foot water is very deadly to the eyes. 4, Q: But the root cause of this problem is that you usually point eye drops too randomly, usually said that we will have a lot of eye discomfort symptoms, you give us a brief description. A: Our eyes are generally random eye drops, generally confined to ocular surface diseases, because there are many other diseases in our eyes, such as glaucoma or cataract, or fundus hemorrhage, which cause vision loss, such patients will generally go to the hospital, the most easily ignored some ocular surface diseases, such as eye dryness, itchy, with These ocular surface diseases patients like to blink, sometimes he even blinked when he felt the eyes grinding, he would like to peel the eyelids, is such a feeling, and some ocular surface diseases is redness and increased secretions, these two symptoms are generally seen in the eye infection, so the patient will need to go to the hospital to see a doctor. 5.Q: Xiao Zhao ordered eye drops hoping that his eyes would not be so dry, but instead, he ordered eye drops to make his eyes even more dry, why is this? A: The problem arises in two aspects, the first is his long-term frequent use, the second aspect, due to long-term frequent use, the drops contain preservatives, this preservative actually has two roles, one is to extend the shelf life of the drug, it can make the drug shelf life of two years, the second has an antibacterial effect, so that we open the eye drops after the bottle, to prevent other Then the drug inside the preservative is allowed, because it content is very trace, but the long-term frequent point with preservative eye drops, it may be harmful, it destroyed the eye surface of the microenvironment, and even cause the corneal epithelium to fall off, a feeling of dryness, so the more points the more dry, counterproductive. 6, Q: eye drops have preservatives inside, this I’m still surprised. A: This is a phenomenon that many people ignore, because eye drops any drug has an active ingredient, the active ingredient is the cure, if we in order to make this drug to maintain a certain long time, after all, there are still some to maintain a certain osmotic pressure, to maintain a certain PH value, but also can add some other added ingredients, then the preservative is a member of this added ingredient, it is allowed, because the preservative has Many kinds of preservatives, we can also see in the food preservatives, drugs are the same. 7, Q: For the average citizen, if you buy eye drops, he can know that the eye drops have preservatives inside? A: Generally speaking, he is certainly not very familiar with the name of the drug, but there is a common sense, because we have different packaging forms of eye medicine, for example, there is a single package, that is, once discarded type, this kind of words are generally not preservatives, if the drug is more than one milliliter, so that the eye drops point after a lot left, so it must have preservatives, if there is no preservative. If there is no preservative, it will break down and grow bacteria, so if the eye drops are greater than one milliliter, they basically contain a preservative, but what kind of preservative is this preservative, whether there is damage to the cornea, is this. 8, Q: We also brought a few of the more common eye drops that can be bought today, such as this benzalkonium, this is a preservative, so I think this business is still better, it has all the ingredients are written out, but in addition there are some not written to this ingredient, then there is what kind of preservative it? A: For example, triclosporin (phonetic), which is more commonly used preservatives in our country, with the progress of technology, our country and foreign countries are studying better preservatives, which both play a role in antibacterial, while the eye damage is less, for example, we have a photosensitive, it is a light this preservative disappeared, so then the preservative on the eyes to minimize the infringement. There is another kind of packaging to do the article, we package it does not come into contact with the air, so such drugs do not need to add preservatives, so with the progress of technology, preservatives will be less and less harmful to people. 9, Q: From the current stage, choose which eye drops should not be used frequently for a long time, because it will damage the environment of some eyes. Our viewers called today, after watching today’s program to know that there are preservatives in eye drops, I want to know if there is no preservative-free eye drops on the market, anti-fatigue can also prevent dryness? A: The symptoms of dryness in our market, we have to look at the specific reasons, if you ask whether there is such an eye drop, there is, single-package artificial tears, many of our international companies and our country are producing such single-package artificial tears, such as Behran ah, Rexin ah (phonetic) and Avery, including preservatives, and there is no preservative, we look at its packaging. If it is a single package, a small one, are no preservatives. If you buy eye drops from the pharmacy, most of them contain preservatives, and if they do not contain preservatives, they must be prescribed by a doctor. We can buy two kinds of drugs in the pharmacy, one is called OTC, that is, over-the-counter drugs, it is a health name, we can generally just buy, there is a prescription drug, such drugs can have no preservatives in the artificial tears. 10, Q: Mr. Li in Beijing, I have been wearing contact lenses, recently feel that the eyes are often very dry, every morning without some eye drops can not even open their eyes, there is a good way to solve it? A: The best way he should wear contact lenses correctly, which is the most important, but indeed if he has this dry situation, appropriate can add a little artificial tears, to solve the problem of dryness. 11, Q: this problem is very serious, is the point of eye drops even point out the glaucoma, this is why it? A: This problem appears in what place it appears in his use of eye drops containing hormones, this hormone is for what it is, it is mainly for some special diseases of our eyes, not about ordinary conjunctivitis, trachoma such cases, it is mainly for the very serious diseases of our eyes, such as iritis, tympanitis, etc., must be special circumstances to use. The second is the role of this hormone component is what, mainly anti-inflammatory effect, anti-allergic, and even anti-immune effect, its role is completely different from the ordinary antibiotic eye drops, he used a month after the long-term, so when he did not often review, resulting in glaucoma. 12.Q: How can hormones have such side effects? A: Hormone is a special drug, it is actually a double-edged sword, is a more favorable weapon in the hands of our doctors, but if you do not use it according to medical advice, it will cause many side effects, such as hormonal glaucoma, and for example, cataract, and can cause some fungal infections, bacterial infections, so such drugs must be prescribed in the doctor to use the drug, but we do not need to talk about Some patients come to us and refuse the hormonal eye drops prescribed by our doctors, which is also not right. 13.Q: Can we buy eye drops containing hormones in pharmacies? A: Generally speaking, eye drops containing hormones are prescription drugs and cannot be bought. 14.Q: Ms. Sun in Jiangsu, her father suffers from glaucoma and must order eye drops every day to control the eye pressure. A: If long-term use there are definitely side effects, the first side effect is what we have said before, one is dry itch, because patients with glaucoma he often do not use a glaucoma drug, with a variety of eye drops, and long-term frequent points, so that may cause dry eye, there is also a relatively easy to ignore the phenomenon of some anti-glaucoma eye drops, the heart, the respiratory tract can have an impact, and even if the drug is not properly used, such as the heart, the respiratory tract can be affected. Even if the medication is not appropriate, for example, he feels that this eye pressure has recently been high, the doctor said you can only point once or twice a day, the results of his point more than a dozen times, so then induced cardiac arrhythmia, and even angina, etc., so it is necessary to follow medical advice. 15.Q: Is it necessary to keep ordering eye drops when you have glaucoma? A: Glaucoma is a special disease, glaucoma is a large group of people, this disease sometimes need to use an eye drops, if bad, but also with two, or even three, to combine drugs, if you do not do surgery, because glaucoma is a lifelong disease, if you do not do surgery to reduce intraocular pressure, then the eye drug is an alternative treatment, glaucoma primary Many of my patients have glaucoma and their eyes are red and uncomfortable, and many doctors don’t know that their patients suffer from this, because long-term eye medication can cause damage to the eyes, which is very common. two kinds, to treat eye surface diseases. 16, Q: there are many people will have this problem, at first think this drug works especially well, the results of the use of the drug to find a large dose, the results still do not work, this is the drug expired? A: The drug has not expired, this actually use a drug resistance, we have a variety of eye drops, anti-glaucoma, cataract treatment, anti-inflammatory, etc., each kind of eye drops used for a certain period of time, it may not work, because you long-term frequent point eye drops, may not have a good effect on the treatment of this disease, is such a situation. 17.Q: How long does it usually take to develop drug resistance? A: Generally three to six months, long-term frequent points may appear a drug resistance. 18, Q: In addition, we also note that in the eye drops also add other ingredients, such as chloramphenicol, which we just mentioned, it belongs to the antibiotic class? A: Yes, any antibiotics, including its active ingredients and its additives, the active ingredients themselves, it will have some side effects, because we can be used by the eyes only about 10%, then 90% of the words, sometimes flow out, there is a part of our body mucous membrane is absorbed, then these absorbed ingredients if you long-term frequent. Some people even point more than ten years, for example, chloramphenicol can cause aplastic anemia in our children, and we are now particularly common eye drops active ingredients, in children, we must pay special attention to parents must read the instructions, the instructions will say whether this drug has been tested for safety, if it has not been tested for safety, when children use it will be on his If it has not been tested for safety, when the child uses it will cause growth disorders. 19.Q: What do parents mainly look for when they read the instructions? A: Because each parent is very caring for their children, I understand, so you look at whether it has been tested for child safety, if it is suitable for children over two years old point, then you can give children over two years old point, if not, you should not give children point. 20, Q: a Ms. Liu said that the eyes often uncomfortable, to the hospital after the doctor gave me a kind of potion, and then a friend recommended a kind of, I often several kinds of change, so can it? A: This situation is actually the medication is not standardized in several ways, a situation is the random use of drugs, often change the drug, listen to friends say this is good to use this, the second is to increase the number of times at will, he felt that the more times the point, the better the effect may be, in addition to an interval may also be irregular. 21, Q: Mr. Zhong in Hunan, these days the eyes are particularly uncomfortable, go to the hospital to see, the doctor prescribed me eye drops, let me use a week, but I point three days on the eyes, then I have to listen to the doctor to continue to use drugs? A: I think this still need to point a few more days, because any of our drugs have a course of treatment, our symptoms are good for a few more days, then you can consolidate, and then three or four days if good, you can stop the drug, we want any medication, whether it is a course of treatment or how long, how to use, how often, these are best according to the doctor’s medical advice, because the doctor to you is the scientific advice. Eye drops storage tips: First, in general eye drops should be placed in a cool freezer at low temperature, most eye drops 2-8 degrees on; Second, if there is no refrigerator can be placed in a cool, ventilated indoor place, should not be placed in a higher temperature or direct sunlight; Third, eye drops should be used up within a month after opening. Tips for using eye drops: First, please wash your hands first to avoid finger contamination to the eye drops; Second, open your eyes and look upward, use your index finger to gently pull down the lower eyelid, or pinch the lower eyelid with your thumb and index finger to gently pull the lower eyelid open, align the eye drops with the mouth of the bottle, the bottle is about two to three centimeters away from the eyes when dropping the medication is best, the mouth of the eye drops bottle to avoid contact with the eyes or conjunctiva to prevent contamination of the drops bottle. Eye drops should be dropped into the groove between the eyelid near the outside and the white eye, not the drops on the black eye; three, after dropping eye drops, the eyes gently loosen, with a sterile cotton ball to dry the spilled drops; four, point eye drops to gently close the eyes after the eyes closed for 3 minutes, can increase the time of contact between the drops and the eye, with the function of promoting the effectiveness of the drug. 22, Q: I found a lot of friends around me are randomly using eye drops, no matter what the situation to pull out a little, which can cause a lot of harm. A: Yes, the film should be very comprehensive, but I think there are two more points need to add, the first is that if usually only one kind of eye drops then it is relatively good solution, is to use in accordance with the correct method can be, but sometimes there is a patient point two kinds of eye drops, then there should be an interval between the two eye drops, this interval is generally in about 5 to 10 minutes, can make both The second point to emphasize is that the shelf life of our eye drops is generally two years, but if you open the bottle of eye drops, it is at most one month, this is very important, we should pay attention to. Many patients feel very good after using this eye drops, put it on the side, and again if the discomfort, it may be six months later he still want to use, in fact, it has expired, and there may be long bacteria inside, so the use of not only no effect, but will cause great harm to the eyes. 23, Q: that eye drops can be given to others to use? A: Generally speaking, you do not point eye drops do not contact the eyes, if you contact the eyes, you would have if it is an infection of the eyes, after contact will cause the source of infection, I would also like to add two points that Professor Wei said, and the third point is a problem of light, because some antimicrobial eye drops, it must be protected from light, the hospital to give you a small black bag, this is to protect from light, you must also go home to protect from light. You must also go home to avoid light, this is a very important point, otherwise the drug will not work. 24, Q: We notice that now on the market in addition to eye drops, recently there is a new thing on the advertising, we are particularly interested in this, there is a kind of eye wash drops on the market, it is eye medicine, it can play a role in cleaning the eyes and relieve discomfort? A: It is not an eye drops, it is at best a kind of health care has a protective effect of liquid, its role is only to wash the eyes, it needs to use the eye cup, pour in the eyes, and then the eyes turn to wash the eyes, it plays a short-lived role of lubrication of the eye, it is not an eye drug. 25, Q: Is it really necessary to wash our eyes so often? A: I think there is a misconception here, in fact, our eyes are immersed in a tear, this tear is a buffer, it is not just water, it also has oil, oil is to prevent the evaporation of tears, and a variety of proteins, immunoglobulins, there is a defensive role, that is, it is a very rich nutrient, that if we wash the eye, and frequent eye spot, it will take our Their own tears are washed away, instead of artificial, this artificial in any case is not able to catch up with our own, so if you do not have a disease, you try not to disrupt our own normal an ecological balance. 26, Q: Ms. Ma of Zhejiang, wear contact lenses every day, a little inattention will get conjunctivitis or keratitis, can use some eye drops to prevent eye problems? A: Generally, if there is no special eye disease, such as he wears a myopic lens, there is no some inflammatory conditions, in the previous is not necessary to prevent the use of drugs, we oppose the arbitrary use of drugs. 27, Q: I suddenly remembered that the folklore of eating fish eyes or something good for the eyes, this has a scientific basis? A: This really does not have any scientific basis, but I know that, for example, our wolfberry, wolfberry is clearly good for the eyes.
