Method for correcting myopia and medication after operation

Abstract: considering the factors of safety, simplicity, economy and practicality, the ophthalmologist believes that for most people, the preferred method to correct myopia is still to wear frame glasses. If patients are going to choose excimer laser surgery, the most concerned problem is the safety of surgery.

method for correcting myopia

1. Lens correction: including frame glasses and corneal contact lenses;       2。 Corneal refractive surgery: radial keratotomy (RK), excimer laser keratectomy (PRK), excimer laser in situ keratomileusis (LASIK), etc;     3。 Intraocular refractive surgery: clear lens extraction, intraocular lens implantation with lens, etc. It should be pointed out that in terms of safety, simplicity, economy, practicality and other factors, the ophthalmologist believes that for most people, the preferred method to correct myopia is still to wear frame glasses. If patients are going to choose excimer laser surgery, the most concerned problem is the safety of surgery. Objectively speaking, the safety of excimer laser surgery is relatively high. Compared with the first radial keratotomy for myopia with diamond knife, its safety has undergone a qualitative leap. After more than 10 years of clinical practice, it has been fully proved. It can be said that laser surgery for myopia has been relatively mature in China. However, the success rate of any operation can not be 100%, just like contact lenses are easy to infect and endanger vision, and the trauma caused by the rupture of frame lens is also one of the reasons for blindness. According to the article in the American Journal of Ophthalmology, the failure rate of such eye surgery is 1 / 10, and most refractive surgery experts in China disagree. Of course, good surgical equipment, skilled operation and rich experience of surgeons, and good cooperation of patients are the basis of high safety of surgery. Any operation has risks, and laser surgery for myopia can not completely avoid complications. The most common complication is over correction or insufficient correction, which should be observed for a certain period of time and reoperation as appropriate; Some people can have glare, that is, a light spot can be seen as a light mass and halo at night, which can be gradually reduced with the passage of time after operation due to slight edema reaction between corneal tissues or large pupil at night, and its edge is close to the operation edge; Keratoconus occurs in people with this potential or too thin cornea after surgery; Eccentric cutting may occur due to poor fixation of the target, or central island may occur due to the effect of water and air swirling on the corneal surface; After PRK and LASEK surgery, there may be corneal haze and hormonal ocular hypertension caused by long-term use of anti haze drugs. LASIK has complications related to corneal flap, such as subflap foreign body, corneal flap displacement and dissolution, increased astigmatism, conscious dryness of eyes, etc. The most serious is the infection of corneal wound in surgery. Although it rarely occurs, it is the direct cause of blindness. Therefore, strict surgical disinfection system and good hygienic habits of patients are very important. After the operation, the eyes should also be checked regularly, paying special attention to the changes of fundus macular area and peripheral retina, so as to prepare for a rainy day. Strict postoperative medication and reexamination are important links. Some patients have unsatisfactory results or complications because they do not use medication and reexamination in strict accordance with the doctor’s instructions. Therefore, we should pay special attention to doctors and remind patients to pay attention to postoperative matters. Generally, the eyes will have sour tears and foreign body sensation 1 ~ 2 hours after LASIK operation, and the symptoms will basically disappear after two or three hours. If the symptoms of eye pain are obvious, pay attention to distinguish whether it is eye skin pain or eye pain. If it belongs to the latter, immediately find an ophthalmologist to eliminate the possibility of infection and corneal flap displacement. When there are eye symptoms on the day of operation, you can close your eyes and rest. Do not remove the transparent eye mask at will. Do not squeeze your eyes and rub your eyes. The next day, the doctor took off the transparent eye mask and checked the visual acuity, cornea and refractive status in the hospital, and then rechecked 3 days, 7 days, January, March, half a year and one year after the operation. Especially in the early stage after operation, doctors can adjust the medication in time according to the review results, which is also an important part to ensure the success of the operation. Patients should also be instructed to avoid places with large smoke and dust within a week after the operation, eat less spicy and stimulating food, do not make up for the eyes, and avoid water and small particles entering the eyes. Many people recovered their normal vision the next day after the operation, but their vision fluctuated in the next few days. Some people’s vision gradually returned to normal, mostly stable in two weeks, and the final recovery period was from March to June. After LASIK, antibiotics can be taken orally for three days to prevent infection; Also point to antibiotic eye solution, hormone eye solution and eye solution that promotes corneal epithelial growth, lubrication and anti drying, generally no more than one month. Use less close-up fine eyesight (including watching computer and TV) within one month. After the operation, due to the change of refractive state, some people will feel difficulty in near vision and easy to fatigue in the early stage. If work and study cannot be avoided, they should have more intervals, blink more and rest more. Generally, the symptoms disappear gradually with the passage of time. In addition, we should pay attention not to swim within a month. We should avoid diving and fierce antagonistic sports to avoid hitting the eyes, causing eye trauma, corneal flap displacement or even loss. When there are glare symptoms, you should wait until the symptoms disappear before driving at night.
