How to select appropriate correction degree for femtosecond surgery in Wuhan Honghui Hospital
The eye is one of the important sense organs of our human body, and myopia is one of the common vision problems. With the development of modern medical technology, femtosecond laser surgery has become a common method to correct myopia. When choosing the appropriate degree of correction, many factors need to be considered, including the degree of myopia, corneal curvature, etc. This article will elaborate on how to select the appropriate correction degree for femtosecond surgery in Wuhan Honghui Hospital from four aspects.
Corneal detection and measurement
The key of femtosecond laser surgery is to create a concave convex surface with proper shape on the patient's cornea, thus changing the refraction of light. Therefore, the detection and measurement of cornea is an important step to select the appropriate correction degree. Generally speaking, the hospital will use professional equipment to conduct intensive detection on the cornea, including the radius of curvature, corneal thickness, corneal diopter and other parameters. Through the analysis of these data, doctors can accurately determine the degree of myopia of patients and select the appropriate correction degree.
In addition, according to the individual differences of patients, such as the degree of curvature of the cornea, astigmatism of the cornea, etc., the doctor will make personalized adjustments when selecting the degree of correction to ensure the maximization of the surgical effect.
Individual differences and selection of correction degree
There are great individual differences in the degree of myopia and corneal condition of different patients, so it is necessary to comprehensively consider these individual differences when selecting the appropriate degree of correction. In general, the higher the degree of myopia, the greater the degree of correction required. In addition, the degree of astigmatism of the cornea will also affect the choice of the degree of correction. The doctor will work out the most suitable correction degree according to the individual condition of the patient and the results of corneal detection and measurement.
It should be noted that too high or too low the degree of correction may have a negative impact on the patient's vision. Therefore, when choosing the degree of correction, doctors need to consider various factors comprehensively and make decisions based on full communication with patients.
Surgical prediction and adjustment
Before femtosecond laser surgery, doctors will use advanced ophthalmic equipment to conduct a comprehensive visual examination of patients and make surgical predictions. Through prediction, doctors can judge the vision of patients after surgery and fine tune the degree as needed. Surgical prediction and adjustment is an important link to ensure the effect of surgery, which can maximize the success rate of surgery and reduce postoperative complications.
Summary
When choosing the appropriate degree of correction, Wuhan Honghui Hospital focuses on corneal detection and measurement, determines the degree of myopia of patients according to corneal parameters, and makes personalized adjustments. The hospital also fully considers individual differences and selects the most appropriate correction degree according to the degree of myopia and corneal astigmatism to ensure the best surgical effect. In addition, surgical prediction and adjustment are also important links, which can improve the success rate of surgery. Through scientific methods and individualized adjustment, Wuhan Honghui Hospital selects appropriate correction degree for femtosecond surgery to provide high-quality myopia correction services for patients.
