Refractive errors such as myopia, hyperopia, and astigmatism not only affect quality of life but also cause inconvenience in daily activities. Femto LASIK, an advanced refractive surgery technology, offers a safe and precise solution for vision correction, improving eyesight for millions worldwide.
Let Hoan My Gold Ky Dong guide you through a deeper understanding of Femto LASIK, how it works, and whether it is the right choice for you.

1. What is Femtosecond LASIK?
Femto LASIK is an advanced refractive surgery that utilises modern laser technology to correct myopia, hyperopia, and astigmatism. Unlike traditional LASIK, Femto LASIK relies entirely on laser technology without the need for a surgical blade.
This technology was approved by the U.S. Food and Drug Administration (FDA) in 2001 and has since become the gold standard in ophthalmology across many developed countries.
2. How does it differ from traditional LASIK?
Both LASIK and Femto LASIK use laser technology to treat refractive errors. However, the key difference lies in how the corneal flap is created and the precision of the procedure.
2.1. Traditional LASIK
Traditional LASIK employs a microkeratome (a surgical blade) to create a corneal flap, which is then lifted to expose the underlying corneal tissue. An excimer laser then reshapes the cornea to restore vision.
- Advantages: Quick procedure, painless, bloodless, and vision recovers within a few days. The cost is relatively affordable.
- Limitations: Not suitable for individuals with thin corneas, myopia exceeding 10 dioptres, or astigmatism above 5 dioptres. The use of a microkeratome may increase the risk of corneal flap-related complications.

2.2. Femto LASIK
Femto LASIK is considered a superior and more modern technique as it combines two advanced laser technologies. The femtosecond laser creates an ultra-thin, smooth, and precise corneal flap, while the excimer laser reshapes the cornea according to the necessary refractive parameters to restore vision.
Blade-free procedure minimises complications and ensures a quicker recovery. So, it is suitable for patients with thin corneas, myopia up to 13 dioptres, and astigmatism up to 6 dioptres, overcoming the limitations of traditional LASIK.
Table 2.1. Comparison of LASIK and Femto LASIK
Criteria | Traditional LASIK | Femto LASIK |
Corneal flap creation | Microkeratome. | Femtosecond laser. |
Precision | Relatively accurate. | Micron-level accuracy due to laser technology. |
Recovery time | One to several days. | Possible from the next day. |
Risk of complications | Possible flap-related issues due to the microkeratome. | Minimised risks due to laser technology. |
Ideal for | – Individuals with thick corneas, myopia below 10 dioptres, and astigmatism below 5 dioptres. – Individuals who do not need to return to work or daily activities immediately after surgery can arrange time for rest to allow their vision to recover. | – Individuals with thin corneas, myopia up to 13 dioptres, and astigmatism up to 6 dioptres. – Busy individuals who require a quick recovery to resume work or daily activities. – Those who wish to minimise the risk of complications associated with surgical blades. |
Femto LASIK is ideal for patients requiring high precision and quick recovery, especially professionals such as pilots, surgeons, or athletes. Meanwhile, traditional LASIK remains an effective solution for those without strict corneal thickness or recovery time constraints.
3. Outstanding advantages of Femtosecond LASIK
Femto LASIK offers several superior benefits thanks to its cutting-edge laser technology:
- Blade-free: 100% laser-based, ensuring safety and minimising tissue damage.
- High precision: Corneal flap thickness is controlled to the micron level, making it suitable even for thin corneas.
- Quick recovery: Normal activities can resume within 1-3 days.
- Minimised complications: Reduces intraocular pressure during surgery, lowering the risk of increased eye pressure or retinal ischemia.
- Fewer side effects: Less dry eye syndrome, halo effects around lights, or night vision disturbances.
Due to these advantages, Femto LASIK has become the preferred choice for many patients seeking safe and effective refractive error treatment.

4. Who is suitable for Femto LASIK?
Femto LASIK is an ideal solution for the following candidates:
- Age: 18 years and older, with stable refractive errors for at least six months.
- Refractive error: Suitable for individuals with myopia (up to 13 dioptres), astigmatism (up to 6 dioptres), or hyperopia, provided their prescription has been stable for at least six months.
- Thin corneas: Recommended for those ineligibles for traditional LASIK due to corneal thickness limitations.
- Eye health: No pre-existing corneal diseases, retinal disorders, or severe eye conditions such as glaucoma.
A thorough consultation with an ophthalmologist is essential to determine suitability for Femto LASIK.
5. How is the Femtosecond LASIK procedure performed?
The Femto LASIK procedure typically involves the following steps:
- Preoperative assessment: A comprehensive eye examination to evaluate corneal health and suitability.
- Anaesthesia: Topical anaesthetic eye drops to ensure a painless experience.
- Corneal flap creation: The femtosecond laser forms a thin, smooth, and precise corneal flap.
- Corneal reshaping: The excimer laser sculpts the corneal surface according to the required refractive correction.
- Finalisation and care: The corneal flap is repositioned, and post-operative care instructions are provided.
The entire procedure takes only 5-10 minutes per eye and is painless.

6.1. Before surgery
- Stop wearing soft contact lenses one week (or hard lenses two weeks) before surgery.
- Avoid using cosmetics or eye care products on the day of surgery.
- Undergo necessary tests and eye examinations as instructed by the ophthalmologist.
6.2. After surgery
- Use prescribed eye drops as directed.
- Avoid rubbing eyes or exposure to dirty water in the first week.
- Minimise exposure to bright light and prolonged screen time for 1-2 weeks.
- Refrain from applying eye creams or makeup for 2 weeks post-surgery.
- Attend follow-up appointments for recovery monitoring.
- Avoid contact sports or strenuous activities for 4 weeks post-surgery.
