Advantages and characteristics of full femtosecond surgery include:
1. Faster healing: Full femtosecond surgery uses a laser to create a corneal flap in the cornea. Compared with traditional surgery, patients usually experience a faster healing process. This means faster vision recovery and less discomfort and dryness.
2. Higher safety: Full femtosecond surgery reduces the risk of mechanical and manual errors and improves the safety of surgery. Corneal surgery is completed by laser, which reduces the possible complications in the operation.
3. Less side effects: Full femtosecond surgery can reduce the risk of irregular or damaged corneal flap, thus reducing the risk of postoperative complications such as dry eye and corneal scar.
However, full femtosecond surgery also has some limitations and disadvantages:
1. Higher cost: Compared with semi-femtosecond surgery, the cost of surgical equipment and technology is higher, which may lead to a corresponding increase in surgical expenses.
2. Restricted indications: Full femtosecond surgery has certain requirements on the shape and thickness of cornea, so it is not suitable for all patients. The doctor will evaluate whether it is suitable for full femtosecond surgery according to your personal situation.
Advantages and characteristics of semi-femtosecond surgery include:
1. Mature technology: Semi-femtosecond surgery has been widely used for many years, and a large number of clinical data have been accumulated, which proves its safety and effectiveness.
2. Wide applicability: Semi-femtosecond surgery is suitable for different degrees of myopia correction and can be combined with other laser surgery techniques (such as PRK).
However, semi-femtosecond surgery also has some limitations and disadvantages:
1. Slow healing: Semi-femtosecond surgery needs to create a corneal flap on the cornea. Compared with full femtosecond surgery, the healing time may not be so fast, and patients may need more time to recover their vision.
2. The risk of complications is high: the use of scalpel to create corneal flap in semi-femtosecond surgery may increase the risk of some potential complications, such as infection and irregular corneal flap.
It should be emphasized that whether it is full femtosecond surgery or semi-femtosecond surgery, the choice of the appropriate surgical method should be decided by the doctor according to your personal situation and eye health. The doctor will comprehensively consider your myopia, corneal thickness, corneal morphology and other factors, and discuss the advantages and disadvantages of various surgical techniques with you in detail in order to provide you with the best treatment plan.
