Shanghai Eye Hospital: What are the risks of H New Vision surgery?
Ophthalmic surgery is a complex and delicate process. Although modern technology has greatly reduced the risk of surgery, there are still some risks. Shanghai Eye Hospital is a reputable ophthalmic hospital, which provides a variety of advanced treatment methods, including H New Vision Surgery. This article will elaborate on the risks of H New Vision surgery from the aspects of preoperative risk assessment, potential risks during the operation, possible complications after the operation, and risks in the recovery period.
Preoperative risk assessment
Before H New Vision surgery, the hospital will conduct a detailed preoperative evaluation to ensure the safety and adaptability of the surgery. However, due to the different physical conditions of each person, preoperative assessment cannot completely eliminate the risk of surgery. Some possible preoperative risks include:
1. Drug allergy: During the preoperative evaluation, the patient will be asked whether there are allergic reactions to certain drugs. If there is a history of allergy, appropriate alternative drugs need to be used.
2. Other eye diseases: some eye diseases, such as keratitis and glaucoma, may increase the risk of surgery and may lead to failure of surgery.
3. Chronic diseases: diabetes, hypertension and other chronic diseases may increase the risk of surgery, and these factors need to be fully considered in preoperative evaluation.
Potential risks during operation
H New Vision surgery is a kind of surgery that uses laser technology to correct myopia. There are some potential risks during the surgery. Although the probability of occurrence is very low, attention should still be paid to:
1. Infection: The instruments and materials used in the operation may cause infection, so strict aseptic operation is required during the operation.
2. Foreign body feeling or discomfort: foreign body feeling or discomfort may occur after the operation, which is caused by the reaction of the eye tissue, and will generally relieve itself within a few days after the operation.
3. Keratitis: If improper care or other sources of infection exist after surgery, keratitis may result, which may require additional treatment.
Possible complications after operation
Although the risk of H New Vision surgery is relatively low, there are still some potential complications:
1. Vision fluctuation: the recovery time of vision after surgery is different, and vision fluctuation may occur in the first few weeks, but it usually gradually stabilizes.
2. Dry eye: The operation may cause dryness and discomfort in the eyes, which is caused by the reduction of tear secretion caused by opening the eyes for a long time after the operation. In most cases, it can be alleviated by effective eye drops.
3. Corneal scar: In a few cases, surgery may lead to corneal scar, which may affect vision, and further treatment is needed.
Risk during recovery period
The recovery period after surgery also has certain risk factors:
1. Infection: During the recovery period after surgery, due to the sensitivity of the eyes to the external environment, external microorganisms are easy to cause infection, and attention should be paid to hygiene and nursing in daily life.
2. Trauma: During the recovery period after surgery, it is necessary to avoid strenuous exercise and external eye force collision to prevent the surgical site from being damaged.
3. Abnormal reactions: In a few cases, abnormal reactions such as decreased vision, eye pain or redness and swelling may occur in the recovery period after surgery, which requires timely medical treatment.
To sum up, although H New Vision Surgery is a relatively safe and effective myopia correction surgery, there are still some risks, including preoperative assessment risks, potential risks during the operation, possible complications after the operation, and risks in the recovery period. Therefore, before accepting surgery, it is recommended that patients fully communicate with doctors to understand the risks of surgery, and carry out preoperative evaluation and postoperative care according to the doctor's recommendations to ensure the safety and effect of surgery.
