What is the difference between femtosecond technology and traditional myopia surgery in Wuhan Tongji Hospital?

As a well-known medical institution in China, Tongji Hospital has advanced medical equipment and expert team, providing a variety of surgical options for myopia patients. Among them, femtosecond technology as an advanced myopia surgery technology has been favored by the majority of patients. This article will elaborate on the differences between femtosecond technology and traditional myopia surgery in terms of objectives, surgical principles, surgical methods and postoperative recovery.

1、 Different goals

The main goal of traditional myopia surgery is to reduce corneal curvature through corneal ablation, so as to achieve the effect of correcting vision. The main goal of femtosecond surgery is to adjust the shape of the cornea and achieve myopia correction. Traditional surgery relies on scalpel for cutting, while femtosecond technology uses high-energy laser to complete corneal cutting and shape adjustment in seconds.

Femtosecond technology can adjust the corneal curvature more accurately to avoid excessive cutting and shape mismatch. At the same time, femtosecond surgery can not only correct myopia, but also treat eye problems such as astigmatism and presbyopia.

2、 Different surgical principles

Traditional myopia surgery changes the shape of the cornea by cutting the cornea, thus changing the refraction of the eye. Femtosecond technology uses laser to cut and shape the cornea layer by layer to change the refractive state of the cornea.

Femtosecond technology uses special laser tools to cut the cornea layer by layer through accurate laser pulses to form a natural corneal surface, thus achieving vision correction. This method can not only reduce the risk of surgery, but also improve the accuracy of surgery.

3、 Different surgical methods

Traditional myopia surgery mainly includes laser in situ keratomileusis (LASIK) and surface keratotomy (LASEK). Both of these operations need to cut the corneal surface for correction. Femtosecond technology uses more advanced femto LASIK or ReLEx Smile technology.

Femto LASIK technology uses laser formed corneal flap to correct myopia. ReLex Smile technology forms a small incision in the cornea to complete myopia correction through minimally invasive method. Compared with traditional surgery, the femtosecond technique is more precise and has shorter postoperative recovery time.

4、 Different postoperative recovery

After corneal ablation, traditional myopia surgery needs a period of time to complete corneal healing, and vision gradually recovers after surgery. The femtosecond technique has more fine surgical cutting, shorter corneal healing time and faster postoperative vision recovery.

The recovery process of femtosecond technology is relatively smooth, and patients can usually resume normal daily life within a few days after surgery. In addition, femtosecond technology has less damage to corneal tissue and less discomfort to the eyes after surgery.

Summary

In general, the femtosecond technology of Tongji Hospital is quite different from the traditional myopia surgery in terms of objectives, surgical principles, surgical methods and postoperative recovery. Traditional surgery mainly relies on scalpel for cutting, while femtosecond technology uses laser to adjust cornea. Femtosecond technology has higher accuracy and faster postoperative recovery time, so most patients can choose the most suitable surgical method according to their own conditions.
