Nanjing Military General Hospital, full femtosecond, can you correct astigmatism?

Nanjing Military General Hospital is a well-known medical institution located in Nanjing. It has full femtosecond laser surgery technology and is widely used in ophthalmology. However, many people have doubts about whether the full femtosecond laser surgery technology is suitable for astigmatism correction. In this paper, we will elaborate whether the full femtosecond technology of Nanjing Military General Hospital can correct astigmatism from four aspects.

What is astigmatism?

Astigmatism is a common ophthalmic disease, which leads to blurred vision when people look far and near. Astigmatism is usually caused by the abnormal shape of the cornea or lens of the eye, resulting in inaccurate focusing of light in the eye. The full femtosecond laser surgery technology is a method of reshaping corneal curvature through laser to correct vision problems.

However, for astigmatism patients, it is still controversial whether full femtosecond technology can be used to correct astigmatism.

Principle of full femtosecond technology

All femtosecond laser surgery is a method to correct vision problems by changing the shape of cornea with laser. It uses a high-energy laser beam to peel and carve the corneal layer, and does not need to use a traditional surgical knife during the operation.

The full femtosecond technology has the advantages of high accuracy, less trauma and fast recovery. However, the corneal shape abnormality of astigmatism patients is not a simple spherical deformation, but an irregular shape of a flat spherical surface, which brings challenges to the design of corneal surgery.

Application of full femtosecond technology in the treatment of astigmatism

For astigmatism patients, ophthalmologists in Nanjing Military General Hospital carried out a series of research and practice to improve the application effect of all femtosecond laser surgery technology in astigmatism correction.

First, experts measured and analyzed the patient's eyes in detail through image processing technology to obtain accurate corneal shape information. Then, full femtosecond technology is used in surgery to accurately peel and carve the corneal layer, and individual vision correction is carried out according to the specific situation of the patient.

The research results of Nanjing Military General Hospital show that the full femtosecond laser surgery technology has achieved remarkable results in astigmatism correction. Many patients have significantly improved their vision after surgery, and astigmatism has been effectively corrected.

Summary

To sum up, the full femtosecond laser surgery technology of Nanjing Military General Hospital can effectively correct astigmatism. Although astigmatism is characterized by the irregular shape of the flat spherical surface of the cornea, the experts of Nanjing Military General Hospital, through research and practice, have made individualized surgical design for each patient's special situation and achieved remarkable results. Therefore, if you are an astigmatic patient and are looking for an effective treatment, the full femtosecond laser surgery technology of Nanjing Military General Hospital is a choice worth considering.
