Can dry eye disease be treated with myopia surgery? How long can it be done?

Dry eye syndrome is the main concern before refractive surgery, and the following questions are often encountered in outpatient clinics: Can myopia surgery be done for dry eye? Will dry eyes be noticeable after surgery? Should surgery be performed after dry eye treatment? Dry eye is a common ophthalmic disease now, and more attention should be paid to prevention and systematic management. The following systematically describes the relationship between myopia surgery and dry eye. Feasibility of refractive surgery in patients with dry eye Experts pointed out that refractive surgery is not currently recommended for severe dry eye. From the perspective of clinical practice, the dry eye conditions of patients undergoing refractive surgery are mainly divided into the following three categories : 1. Asymptomatic on weekdays, no obvious abnormality in dry eye examination results: some people have good eye habits, and the function and structure of the meibomian glands are normal, and no additional intervention is required before surgery. At present, the number of electronic devices is increasing and the habits of eye use are generally inappropriate. It is still a minority that the function of the ocular surface remains completely ideal. 2. Occasional symptoms and mildly abnormal dry eye examination results: Most myopic patients fall into this category, especially among women, the elderly, and people who work on computers for a long time and wear contact lenses. These people usually do not know their dry eyes, which is mainly reflected in the inspection indicators. Usually mild dry eyes and other symptoms are not obvious, and it is easy to be regarded as visual fatigue. Usually, these patients can maintain an ideal state of the ocular surface by routine application of artificial tears before surgery. 3. There are dry eye symptoms, and the dry eye examination is mild to moderate dry eye: some patients have severe dry eye symptoms before surgery, and dry eye symptoms can be alleviated by appropriate dry eye treatment methods and nursing measures. After evaluation by doctors, surgery can be performed. Follow the doctor's prescription medication nursing, but also to achieve the desired surgical results. For the vast majority of dry eye patients, refractive surgery is feasible. Refractive surgery itself will not aggravate the original dry eye degree. With epithelial repair and wound healing after surgery, the dry eye caused by surgery can be effective. Relief; from the point of view of the surgical method, the effect of all-femtosecond on dry eye is lighter than that of half-femtosecond and all-laser surgery; therefore, for those with dry eye or risk factors for dry eye, the corneal incision and the amount of ablation need to be evaluated. Under the premise of corneal conditions, more minimally invasive surgical methods are selected. The effect of dry eye on the effect of refractive surgery The effect of dry eye on surgery is mainly reflected in the results of preoperative examination and postoperative visual acuity recovery. Generally, dry eye has no effect on the effect of surgery. The design of refractive surgery is precise, and the repeatability and accuracy of the measurement results are required to be high. For those with abnormal test results caused by dry eye, repeated calibration will be carried out before surgery, and the surgery can be performed after evaluation by a professional doctor before surgery. Postoperative dry eye will affect early vision recovery, mainly due to tear film instability and tear hypertonicity. Meibomian gland dysfunction causes poor tear film stability, which will affect the curvature of the anterior surface of the cornea. At the same time, unstable tear film It has a certain influence on the lubrication of the surface and the transmission of light. Abnormal tear quality can cause dehydration and edema of epithelial cells, affecting the homeostasis of the ocular surface. Strengthening dry eye care and intervention in the early postoperative period will help to achieve better visual effects. How to do preoperative refractive surgery for patients with dry eye: a clear diagnosis is the premise, after a standardized examination, the type, degree, and cause of dry eye are determined, and the doctor evaluates the feasibility of surgery, the method of surgery, and predicts postoperative dry eye degree and the importance of dry eye management. Each type of surgery has its own advantages, and choosing the right surgery can achieve the best postoperative results. Dry eye is a chronic disease, which depends on prevention and management. Most routine preoperative medication and appropriate intervention can keep the ocular surface in an ideal state without affecting the safety and efficacy of surgery. Intraoperative: Preoperative eyewashing and cleaning can reduce the risk of intraoperative infection. Reasonable surgical plan design, doctor's standardization and skilled operation can reduce unnecessary damage. At the same time, patients should cooperate correctly during the operation to reduce the operation time and avoid unnecessary injuries. Steps to make the surgery successful, do the details of the surgery well, and control the impact of the surgery on dry eye to a minimum. After surgery: Anti-inflammatory, artificial tears, growth factors and other drugs are routinely used to promote corneal healing and vision recovery. For those with different degrees of dry eyes before surgery, additional intervention should be strengthened after surgery to maintain normal meibomian glands and eyes. Table function. After surgery, dry eye can be relieved and prevented by hot fumigation, eye blinking training, home care, meibomian gland massage, etc. At the same time, there are also OPT, IPL and other measures that are suitable for those with severe dry eye who need further treatment. Dry eye is common, and dry eye syndrome is an independent ophthalmological disease that needs to be diagnosed after systematic evaluation; refractive surgery is feasible for the vast majority of dry eye patients. 、Intraoperative and postoperative details will be assessed and intervened to minimize the impact of refractive surgery on dry eye, and at the same time, it can help patients achieve comprehensive management of dry eye, control symptoms, delay progress, and form a standardized eye Nursing habits.
