The advantages and features of full femtosecond surgery include:
1. Faster Healing: Full femtosecond surgery uses a laser to create a flap layer inside the cornea, and patients typically experience a faster healing process compared to traditional surgery. This means faster vision recovery and less time spent in discomfort and dryness.
2. Greater safety: Full femtosecond surgery increases the safety of the procedure by reducing the risk of mechanical and manual errors. The corneal manipulation is done by the laser, which reduces possible complications during the surgery.
3. Fewer side effects: Full femtosecond surgery reduces the risk of irregular cuts or breaks in the layers of the corneal flap, which reduces the risk of post-operative complications such as dry eye and corneal scarring.
However, there are some limitations and drawbacks to full femtosecond surgery:
1. Higher cost: Full femtosecond surgery is more costly in terms of surgical equipment and technology as compared to hemi-femtosecond surgery, which may lead to a corresponding increase in the cost of the procedure.
2. Restricted indications: Full femtosecond surgery requires a certain shape and thickness of the cornea and is therefore not suitable for all patients. Your surgeon will assess whether you are a candidate for full femtosecond surgery based on your individual circumstances.
The advantages and features of hemi-femtosecond surgery include:
1. Mature technology: Hemi-femtosecond surgery has been widely used for many years and has accumulated a large amount of clinical data to prove its safety and effectiveness.
2. Wide applicability: Semi-femtosecond surgery is suitable for different degrees of myopia correction and can be used in combination with other laser surgical techniques (e.g. PRK).
However, there are some limitations and drawbacks to hemifemtosecond surgery:
1. Slower healing: Hemifemtosecond surgery requires the creation of a flap layer in the cornea, and healing time may not be as fast as compared to full-femtosecond surgery, and the patient may need more time to regain their vision.
2. Higher risk of complications: A scalpel is used to create the corneal flap in a hemifemtosecond procedure, which may increase the risk of some potential complications, such as infections, irregularities in the flap, and so on.
It is important to emphasize that the choice of the right procedure, whether it is a full femtosecond or hemifemtosecond surgery, should be determined by your doctor based on your personal situation and eye health. Your doctor will take into account your myopia, corneal thickness, corneal morphology and other factors, and will discuss with you in detail the pros and cons of each surgical technique in order to provide you with the best treatment plan.
