Full femtosecond and half femtosecond are both common laser corneal refractive surgeries to correct myopia. Full femtosecond surgery is more accurate, faster recovery but more expensive, while half femtosecond is less accurate and prone to postoperative infections.
Full femtosecond laser surgery is suitable for refractive error patients with myopia of 100 to 1,000 diopters and astigmatism of 400 diopters or less. Full femtosecond cutting is more precise, postoperative recovery is faster, and postoperative dry eye complications are less. However, full femtosecond laser surgery is more expensive and is not suitable for patients with second surgery.
Semi-femtosecond laser surgery is suitable for patients with myopia up to 1200 degrees and astigmatism up to 500 degrees, and patients can undergo multiple surgeries at a slightly lower cost. However, patients are more likely to experience complications such as eye infections and dry eye after surgery.
It is recommended that patients with refractive error consult a doctor in a timely manner to assess their condition and choose a treatment plan that suits their needs under the guidance of a physician.
