Achieving Dreams: Xiao Wang’s Journey to Vision Correction
Xiao Wang (a pseudonym) had always dreamed of joining the military, but his nearsightedness had been a major obstacle. After finishing the college entrance exams this year, Xiao Wang, accompanied by his father, traveled from their hometown in Hunan to the Southern Hospital, seeking a solution to his vision problem. The hospital’s ophthalmology director, Dr. Zhang Hongyang, and his team conducted a comprehensive preoperative examination and confirmed that Xiao Wang was a suitable candidate for the SMILE (Small Incision Lenticule Extraction) procedure, scheduling the surgery shortly thereafter.
On the day of the surgery, Xiao Wang arrived at the SMILE laser vision correction center at the Southern Hospital’s Zengcheng branch, feeling both nervous and excited. The surgery went smoothly and was completed in just a few minutes, with Xiao Wang experiencing almost no noticeable pain. The next day, during a follow-up examination, his vision had already improved to 1.2 in both eyes. Upon returning home, Xiao Wang passed the military medical examination with flying colors, finally realizing his dream of joining the army.
Dr. Ma Ming, head of ophthalmology at the Southern Hospital’s Zengcheng branch, noted that SMILE laser surgery has become the preferred option for many patients seeking clear vision. This innovative technique represents a significant advancement in modern ophthalmology.
What is SMILE Laser Surgery?
SMILE laser surgery is a major breakthrough in the field of corneal refractive surgery, relying entirely on femtosecond laser technology to perform the procedure. Unlike traditional methods, SMILE does not require the creation or lifting of a corneal flap, significantly reducing the risk of surgical complications and postoperative issues. The technique involves precisely controlling the femtosecond laser to create a lens-shaped layer of tissue (known as a “stromal lenticule”) within the corneal stroma, which is then removed through a tiny incision (typically only 2-4 mm). This process alters the cornea’s refractive index, effectively correcting nearsightedness, farsightedness, or astigmatism.
The key advantages of SMILE lie in the precision and non-contact nature of the femtosecond laser. This laser operates in ultrashort pulses (measured in femtoseconds, or 10^-15 seconds), allowing for highly accurate corneal tissue cuts without damaging surrounding tissues.
Who is a Candidate for SMILE Laser Surgery?
SMILE laser surgery is suitable for correcting nearsightedness ranging from 100 to 1000 degrees. It is ideal for patients aged 18 to 50, with astigmatism under 500 degrees, and stable nearsightedness (annual progression of less than 50 degrees). Additionally, candidates must meet corneal thickness requirements and have no other eye diseases or systemic contraindications. It is recommended to undergo a detailed preoperative examination at a reputable hospital to determine eligibility for SMILE surgery.
What is the SMILE Surgery Process?
- Preoperative Examination: Includes vision testing, refraction, corneal topography, and fundus examination, among other rigorous assessments, to confirm surgical suitability.
- Surgical Preparation: Preoperative administration of antibiotic eye drops, eye cleaning, and application of anesthetic eye drops.
- Surgical Procedure: The patient lies down, aligns their eyes with the laser device, and the surgeon operates the laser equipment to complete the tissue cutting and lenticule removal.
- Postoperative Observation: The patient is observed at the hospital for a period after the surgery, and is allowed to leave once no abnormalities are detected.
Post-SMILE Surgery Care
- Regular Follow-Ups: Follow the doctor’s instructions for regular check-ups to monitor vision recovery.
- Medication Guidance: Use prescribed eye drops as directed to prevent infection and alleviate postoperative reactions.
- Avoid Strenuous Activities: Refrain from activities like swimming or diving that may expose the eyes to contaminants during the recovery period.
- Maintain Eye Hygiene: Limit screen time, avoid rubbing the eyes, and maintain good eye care habits.
- Dietary Adjustments: Avoid spicy and irritating foods; instead, consume foods rich in vitamins and proteins to aid recovery.
Finally, Dr. Ma Ming advises patients considering SMILE surgery to plan ahead, choose a reputable hospital and experienced surgeon, and strictly adhere to postoperative care instructions to ensure the best results in achieving a lens-free life.
