Introduction to Full Femtosecond Laser Surgery for Myopia

As a remarkable achievement in modern ophthalmology, laser surgery for myopia has brought hope of restored clear vision to numerous patients. Among them, full femtosecond laser surgery stands out as the preferred choice for many due to its unique advantages. This article delves into the full femtosecond technology in laser surgery for myopia.

Characteristics and Advantages of Full Femtosecond Laser Surgery

1. High Precision: Full femtosecond laser surgery employs femtosecond laser cutting, achieving a precision of micrometers. It accurately controls the depth and range of corneal cutting, ensuring optimal surgical outcomes.

2. Flapless Technology: Unlike traditional laser surgeries, full femtosecond surgery does not require the creation of a corneal flap. Instead, it utilizes a laser to create a microlens within the corneal stroma, which is then removed through a small incision to correct vision. This flapless design minimizes trauma to the cornea and accelerates postoperative recovery.

3. High Safety: Full femtosecond laser surgery is precisely controlled by a computer system, reducing human errors and enhancing surgical safety. Furthermore, its unique surgical approach lowers the risk of complications such as postoperative dry eye syndrome and corneal flap displacement.

4. Rapid Recovery: Due to minimal surgical trauma, patients experience less discomfort and a relatively shorter recovery time. Most patients can resume normal vision and daily activities the day after surgery.

Surgical Process of Full Femtosecond Laser Surgery

1. Preoperative Preparation: Patients undergo detailed ocular examinations, including vision tests, corneal thickness measurements, and fundus examinations, to determine their suitability for full femtosecond laser surgery. Additionally, doctors devise individualized surgical plans based on patients' specific conditions.

2. Anesthesia and Fixation: Before surgery, the doctor administers local anesthesia to the patient's eyes and uses a speculum to fix the eyelids, ensuring that the eyes do not move during the procedure.

3. Laser Scanning: During the surgery, the doctor utilizes full femtosecond laser equipment to precisely scan and cut the cornea. Initially, the laser creates a microlens within the corneal stroma, which is subsequently removed through a small incision, altering the cornea's refractive power to correct vision.

4. Postoperative Care: Following surgery, the doctor dresses and cares for the patient's eyes, providing postoperative medication instructions. Patients must adhere to the doctor's recommendations for medication and follow-up visits to ensure stable surgical outcomes and vision recovery.

In conclusion, full femtosecond laser surgery has emerged as a leader in laser surgery for myopia, characterized by high precision, flapless technology, high safety, and rapid recovery. However, patients should exercise caution when choosing this surgery and thoroughly consult with doctors to ensure its safety and efficacy.
