A successful excimer laser surgery depends not only on the superb surgical skills of doctors, but also on the regular medication and follow-up after surgery. Drug use after excimer laser surgery is particularly important. Use as directed by the doctor. Don't stop taking drugs or abuse them just because you feel good about yourself. At the same time, we should go to the hospital regularly, otherwise it will lead to sequelae of excimer surgery. There was once a college student whose operation was very successful. After 1 week, his binocular vision reached 1.5, but he never came to check again. Two months later, he came back for a follow-up visit because of his sharp decline in vision. The examination found that his vision was 0.4 and his intraocular pressure reached 35mmHg. Asking about the medical history, it turned out that he had been using hormone eye drops, thinking that his vision was normal and he didn't go to the hospital to check the intraocular pressure. He didn't notice it until his eyesight dropped. Although his intraocular pressure returned to normal after active treatment, his vision could only return to 0.8. Hormone eye drops 1 ~ 2 months are usually used after excimer laser surgery to promote postoperative recovery and prevent myopia regression. Hormone eye drops may increase intraocular pressure, which may lead to hormonal glaucoma. Therefore, during the use of drugs after excimer laser surgery, we must go to the hospital for regular review, especially to follow up the intraocular pressure. In addition, for LASIK operators, due to the existence of corneal flap, external force should be avoided after operation to avoid serious consequences of corneal flap displacement.

2, high myopia still needs to be careful

Myopia patients are often accompanied by fundus lesions because of their long axial length, especially those with high myopia, which are characterized by thinning and atrophy of peripheral retina. Once a retinal hole appears, it may lead to retinal detachment. Retinal detachment is a common eye disease caused by myopia, and myopia patients should pay special attention to it. Excimer laser can restore normal vision, but it can't change the changes brought by myopia. Therefore, for myopia patients with normal postoperative vision, they should take care of their eyes like myopia. Precautions for patients with high myopia after excimer surgery are as follows: Attention should be paid to avoiding strenuous exercise such as playing basketball and strong physical labor. When the head is shaken or subjected to heavy physical labor or strenuous exercise, the retina will be pulled and a hole will appear, resulting in retinal detachment. In the early stage of retinal detachment, lightning-like light bands appeared in front of eyes, and the black spots of floaters increased greatly, or the shadows in the field of vision gradually expanded. Once the above symptoms appear, we should attach great importance to them and go to the hospital for treatment immediately without delay. If you wait until your eyesight drops significantly before going to see a doctor, the effect of treatment will be very poor.

3. Pay attention to eye hygiene.

Although the patients undergoing excimer laser surgery are basically adults over 18 years old, the general traditional view is that the vision of adults is relatively stable and it is not easy to further decline, but this is not the case. The Chinese nation is a nation with high incidence of myopia. There are about 400 million myopia patients in China, and the number is increasing year by year. There are not a few people whose myopia is still increasing after the age of 20, which is mainly related to the popularization of computers in modern society and the increasing work pressure. Working close for a long time can still lead to further myopia. Therefore, for people who mainly work in close proximity, attention should be paid to protecting their eyes after excimer laser surgery. Within 1 ~ 2 months after excimer laser surgery, most people have difficulty in seeing at close range. At this time, it is necessary to reduce the time of using eyes at close range, which can not only avoid discomfort such as eye fatigue and soreness, but also help the recovery of eyes. For people whose eyesight has completely returned to normal, they should pay attention to eye hygiene, especially those who spend a long time watching computers and working at their desks. After using eyes 1 hour, you must have a rest. They can do eye exercises to relax their eyes, or look far away to give them a proper rest to avoid the sequelae of excimer surgery caused by excessive use of their eyes.

4. Choose a suitable polarizer after operation.

In the early stage after excimer laser myopia surgery, the corneal sensitivity of patients will decrease. At this time, dust and gravel can easily enter the eyes, and if not handled properly, it will cause corneal damage. In this case, it is very necessary to wear a pair of glasses suitable for the face to block the sand. After excimer laser surgery, most patients still have photophobia. It is recommended to wear a pair of polarized sunglasses outdoors. Polarized sunglasses can eliminate the strong glare caused by light shining on water, glass and smooth road surface, and can effectively protect eyes. And can reduce the damage of ultraviolet rays to eyes. In addition, it is also important to choose high-quality polarizers in eye hospitals with professional qualifications and good reputation. As the main protective tool for eyes after operation, polarizer must be carefully selected. The main function of a pair of qualified sunglasses is to block ultraviolet rays (99% to 100%) and harmful rays, reduce the transmittance of visible light, and effectively protect eyes. Moreover, regular sunglasses belong to the flat mirror series, and the diopter is strictly controlled below 0.008 degrees. A pair of inferior sunglasses may cause serious damage to eyes, ranging from dryness, fatigue, burning sensation, pain, tears, dizziness, nausea and vomiting, to irreversible permanent damage to cornea, lens and retina.

5. Pay attention to the balance of diet and nutrition after operation.

1. Black bean and walnut milk: black bean powder 1 spoon, walnut paste 1 spoon, milk 1 bag, honey 1 spoon. 500 grams of black beans are fried, cooled and ground into powder. 500 grams of walnut kernel, slightly fried, stripped, cooled and mashed into mud. Take the above two foods 1 spoon, pour them into 1 cup of boiled milk, and then add 1 spoon of honey. Take it every morning or after breakfast, or with breakfast. Black beans are rich in protein and vitamin B 1. The nutritional value is very high. Because black food enters the kidney, combined with walnut kernel, it can increase the strength of tonifying kidney. Together with milk and honey, these foods contain more vitamin B 1, calcium, phosphorus and so on. , can enhance the muscle strength in the eye, strengthen the regulation function and improve the symptoms of eye fatigue.

2. Gouqi porridge: 5 grams of medlar, 5 grams of mulberry seeds, 5 grams of yam, 5 red dates, and 0/00 gram of japonica rice/kloc. Boil the above raw materials into porridge to eat. In this prescription, medlar and mulberry seeds can tonify liver and kidney, while yam and red dates can tonify spleen and stomach. If people with visual fatigue can take it for a long time, twice a day in the morning and evening, it will not only eliminate the symptoms of eye fatigue, but also enhance their physique.
