First, let's understand full femtosecond surgery. Full femtosecond surgery uses a femtosecond laser for corneal cutting and a femtosecond laser to create a corneal flap (Flap). Full femtosecond surgery is highly precise and controllable, allowing for personalized surgical planning based on an individual's ocular parameters and refractive error. Advantages of full femtosecond surgery include faster recovery, less incidence of dry eye and better predictive vision outcomes.
Semi-femtosecond surgery is performed in two important steps: the first step involves the creation of a corneal flap by a femtosecond laser, and the second step involves the ablation of the flap by an excimer laser. The process of hemi-femtosecond surgery can take longer and the wound can be larger compared to full femtosecond surgery.
When choosing between full femtosecond and hemi-femtosecond surgeries, please consider the following factors:
1. Visual effect: There is no good or bad in these two surgeries, only suitable or not, different surgeries are suitable for different people as well as different myopia levels. Therefore, it is recommended to go to the hospital for professional examination in order to further determine the appropriate correction plan.
2. Surgical procedure: Femtosecond laser surgery is mainly performed by femtosecond laser to create a corneal flap, and excimer laser to ablate the corneal stroma to change the corneal refractive index, so as to correct refractive myopia. Full femtosecond laser surgery is mainly through the femtosecond laser in the corneal stroma layer to make corneal microlens, the surgeon only need to remove the lens, the surgery is complete, the whole cornea biomechanical more stable.
3. Recovery time: Because the corneal flap creation process is more precise and minimally invasive in full femtosecond surgery, patients are often able to return to their vision and daily activities more quickly. Recovery time for hemi-femtosecond surgery may be slightly longer.
It is important to emphasize that both full and half-femtosecond procedures offer safe and effective myopia correction. Which procedure you choose depends on your individual needs, eye characteristics and your doctor's recommendations.
Before making a decision, we recommend that you have a detailed consultation and evaluation with an eye care professional. Your doctor will recommend the best surgical option for you based on your eye condition, medical history, refractive error and corneal parameters.
