"I like sports very much, but my eyes are nearly 600 degrees myopia and require glasses, which brings a lot of inconvenience to daily life and affects the quality of life. I have always considered surgery to improve my vision, but I heard that there are many types of surgery, such as full femtosecond, half femtosecond, lens implantation, etc., which made me a little confused and did not know which surgery to choose. Are these surgeries safe?"
Recently, a friend called Dr. Zhou Xuxia from the Refractive Center of Zhuzhou Aier Eye Hospital to ask about myopia surgery.
According to Dr. Zhou Xuxia, at present, myopia surgery can be roughly divided into two categories: subtractive surgery (i.e., corneal laser surgery) and additive surgery (i.e., lens implantation surgery).
Corneal laser surgery, including the femtosecond, femtosecond, and laser that we often hear about, corrects vision and astigmatism by changing the thickness and curvature of the cornea.
1. Full femtosecond
ReLEx is femtosecond laser small incision corneal stromal lens extraction, in which femtosecond laser is used throughout the operation.
It first makes a lenticule in the corneal stromal layer and then removes it through a small incision of 2-4mm. This surgery is suitable for correcting myopia from 50 degrees to 1000 degrees and astigmatism within 500 degrees. Features include small incisions, no need for a corneal flap, mild postoperative dry eye symptoms, and corneal biomechanical stability, making it ideal for people who love sports or are preparing to join the military.
2. Half femtosecond
Femtosecond is femtosecond laser-assisted excimer laser in situ keratomileusis, which requires the use of femtosecond laser and excimer laser during the procedure.
A corneal flap is first made with a femtosecond laser, and then the stromal layer is cut with an excimer laser. This surgery can correct myopia up to 1200 degrees, astigmatism and farsightedness up to 600 degrees. It is characterized by a corneal flap and high postoperative visual quality, and is suitable for a wide range of people.
3. All-laser
All-laser transepithelial excimer laser keratomectomy uses an excimer laser to remove the corneal epithelium and stromal layer at one time, which can correct myopia within 800 degrees, astigmatism and farsightedness within 600 degrees. This procedure is flapless, non-scarring, non-contact, and incision-free, making it ideal for people with thin corneas, who love sports, or who are preparing to join the military.
4. ICL lens implantation surgery
ICL lens implantation involves the insertion of an intraocular lens into the eye. This crystal, which is made of a special material, has good elasticity and softness.
Since there is no need to cut the cornea and the structure of the eye is not changed, it is a reversible myopia correction surgery that can correct myopia from 50 to 1800 degrees and astigmatism within 600 degrees. It is characterized by high definition, reversible, wide correction range, and mild postoperative dry eye symptoms, which is suitable for people with moderate and high myopia.
"With so many surgical options, which one is safer?"
Dr. Zhou Xuxia said that the safety of myopia surgery mainly depends on the preoperative examination, surgical process and surgeon. Choosing a professional and authoritative ophthalmology hospital, conducting strict preoperative examinations, choosing an experienced surgeon, following a standardized surgical process, and having regular check-ups on time are safe regardless of the surgical method chosen.
"What are the precautions for preoperative testing, and what kind of surgery is suitable for me?"
Before the examination, you need to stop wearing soft ordinary contact lenses for more than 1 week, soft astigmatism contact lenses and rigid lenses for more than 3 weeks, and orthokeratology lenses for more than 3 months. It is advised not to drive on the day of the examination as mydriatic medication will be used during the examination.
The whole process takes about 2 hours, so please allow enough time to go to the hospital for the examination. After the examination, the doctor will recommend a suitable surgical plan according to the patient's specific situation.
Li Lin, a globally certified expert in ICL/femtosecond/excimer laser surgery, director of Zhuzhou Regional Refractive Center, and president of Zhuzhou Aier Eye Hospital (New Hospital), emphasized: "Myopia surgery is not suitable for everyone. Before surgery, patients need to go through a strict preoperative examination, and the doctor will comprehensively consider the patient's physical indicators to rule out contraindications to surgery. In order to ensure the safety and effectiveness of the surgery, the doctor will 'measure the eye's eyes and customize the personalized surgical correction plan according to the patient's eye needs and eye conditions. ”
As one of the first medical institutions in Hunan Province to carry out refractive surgery, the Refractive Center of Zhuzhou Aier Eye Hospital has brought together an expert team with President Li Lin as the core, Director Le Honghua, Sun Lin, Wang Hao, Zhou Xuxia and other physicians. Relying on the global resource advantages of Aier Ophthalmology Group, the specialty closely follows the international frontier and is committed to technological innovation, providing a variety of surgical methods for myopia patients, including ICL, ReLEx, Trans-PRK surface surgery, personalized femtosecond and Jingdiao.
The specialty has always adhered to the service concept of "personalized, full-process, and customized", and tailored the best myopia correction plan for each myopia patient, so that myopic friends can experience "smiling" and regain clarity.
