ReLEx SMILE and LASIK surgery are two forms of laser vision correction in Singapore. Patients often compare by researching LASIK options in Singapore, such as Smile LASIK, to understand differences in surgical technique, eligibility, and recovery experience. This page outlines the key characteristics of both treatments to support informed decision-making based on individual eye conditions and visual needs.
What Is LASIK Singapore?
In Singapore, LASIK refers to laser vision correction procedures used to treat refractive errors such as myopia, hyperopia, and astigmatism. LASIK (laser-assisted in situ keratomileusis) reshapes the cornea so that light can focus correctly on the retina, helping to improve visual clarity.
During the procedure, the eye surgeon uses either a femtosecond laser or a microkeratome – a small machine-guided surgical blade – to create a thin flap in the cornea. After the flap is lifted, an excimer laser is used to remove a measured amount of corneal tissue by reshaping the central part of the cornea. While the treatment is applied to the central cornea for all patients, the amount of tissue removed varies depending on the type and degree of refractive error being treated.
The procedure typically takes about five minutes for each eye. Patients remain awake during the treatment, and local anaesthetic eye drops are used to numb the eye and reduce discomfort. Recovery time is generally short, with initial healing occurring within a day or two. Many patients are able to resume their normal daily activities the following day, although the eye surgeon may advise avoiding certain activities such as swimming for a few weeks.
What Is Smile LASIK Singapore (ReLEx SMILE)?
SMILE LASIK, also known as ReLEx SMILE (Small Incision Lenticule Extraction), is a form of laser refractive eye surgery available in Singapore. It is mainly used to treat myopia (short-sightedness) and can also correct certain degrees of astigmatism.
Unlike LASIK procedures that involve creating a corneal flap, ReLEx SMILE reshapes the cornea by creating a small incision within the corneal tissue. This lenticule is then removed through a small keyhole incision, which reshapes the cornea to correct vision by improving how light focuses on the retina.
Similar to LASIK, patients undergoing SMILE LASIK in Singapore receive numbing eye drops before the procedure to reduce discomfort. A femtosecond laser, programmed according to the patient’s corneal measurements, performs the treatment. The procedure usually takes about five minutes per eye. Recovery time is generally comparable to LASIK, with vision continuing to stabilise over the days following treatment.
ReLEx SMILE Vs LASIK: What’s the difference?
Difference #1: ReLEx SMILE uses one laser while LASIK uses two
The immediate difference you would notice with ReLEx SMILE is that the procedure only utilises one laser: the femtosecond laser. This tool is used to create a small incision and separate a piece of corneal tissue, which is then removed to reshape the cornea.
Conversely, LASIK procedures in Singapore use two lasers. The femtosecond laser is used to create a flap on the cornea, while a second laser (usually an excimer laser) is used to remove a measured amount of corneal tissue to correct vision. The amount of tissue removed varies depending on the patient’s prescription.
Difference #2: ReLEx SMILE is only suitable for short-sightedness and minor astigmatism
Do you have short-sightedness (i.e. myopia) or astigmatism? ReLEx SMILE can be used to correct myopia of up to approximately 1000 degrees and astigmatism of up to about 500 degrees.
All forms of laser vision correction involve reshaping the cornea by removing corneal tissue, and this is a consideration that will be discussed during the pre-operative assessment. Eye surgeons will perform detailed scans and evaluations to assess the structural suitability of the cornea and overall eye health before recommending any procedure.
If you have long-sightedness or other vision concerns, your eye surgeon in Singapore may discuss alternative treatment options. As suitability depends on multiple factors, it is advisable to undergo a comprehensive assessment with an eye surgeon to determine whether laser vision correction is appropriate for your condition.
Difference #3: ReLEx SMILE has fewer complaints of dry eyes
The incision created during a ReLEx SMILE procedure is 1/5 times smaller than that of LASIK surgery. As a result, fewer corneal nerves are disturbed in the former treatment. Hence, the central cornea sensitivity and tear production system is maintained better than LASIK. Therefore, the chances of post-surgery dry eyes are significantly reduced.
Difference #4: ReLEx SMILE has no flap complications
During LASIK surgery, your eye surgeon will create a 20mm flap on your cornea to serve as a natural protective layer for the site of the operation. However, improper placement of the flap can cause complications like epithelial ingrowth. Conversely, patients who undergo the ReLEx SMILE procedure do not have to worry about such issues since the latter is a flapless eye surgery.
ReLEx SMILE or LASIK Singapore: Which is better for you?
Both SMILE and LASIK are commonly used procedures for correcting certain refractive errors, particularly myopia and astigmatism. SMILE can be suitable for a wide range of prescriptions, including higher degrees of astigmatism, while LASIK may also be considered depending on individual eye structure and clinical assessment.
It is important to note that neither SMILE nor LASIK is typically used to correct hyperopia. Individuals with long-sightedness are more commonly assessed for alternative procedures such as PRK, depending on their eye condition and visual needs.
To determine the most appropriate option, it is advisable to speak with an eye doctor in Singapore for a detailed evaluation. A comprehensive assessment allows the eye specialist to review your prescription, corneal health, and overall suitability.

Key Takeaways: LASIK & ReLEx SMILE in Singapore
- In Singapore, both LASIK and SMILE are commonly used to correct refractive errors such as myopia and astigmatism.
- Each procedure uses laser technology and generally involves a short recovery period, with many patients able to resume daily activities soon after.
- ReLEx SMILE can be an option for individuals who are seeking a flapless procedure, depending on their eye structure and clinical suitability.
- Consulting an eye doctor can help determine which procedure is more appropriate based on your prescription, eye health, and visual needs.
Frequently Asked Questions
How does an eye doctor determine whether LASIK or SMILE is suitable for a patient in Singapore?
An eye doctor assesses suitability through a comprehensive eye examination, which includes corneal thickness mapping, eye surface health, pupil size, refractive error, and overall eye stability. Factors such as lifestyle needs, visual expectations, and existing eye conditions are also considered. These evaluations help determine whether LASIK or SMILE is more appropriate for long-term visual outcomes. More information about the clinic’s approach to assessment can be found on the Home page.
Are there age requirements for LASIK or SMILE surgery in Singapore?
In Singapore, LASIK and SMILE surgery are generally recommended for individuals aged 18 and above, provided their vision prescription has stabilised. Age alone does not determine eligibility, as eye health, corneal condition, and refractive stability play a more important role. An individual consultation is necessary to confirm suitability. Patients with questions about age-related considerations or eligibility can reach out via the Contact Us page for further guidance.
What is the main difference between ReLEx SMILE and LASIK Singapore?
The main difference lies in how the cornea is reshaped. ReLEx SMILE uses a single femtosecond laser to create a small incision and remove corneal tissue, while LASIK uses two lasers and involves creating a flap in the cornea.

Which procedure has a higher risk of complications, ReLEx SMILE or LASIK?
Both procedures are generally considered safe when performed by a qualified eye doctor. However, LASIK carries a small risk of flap-related complications since it involves creating a corneal flap, whereas SMILE does not. If you have concerns about potential risks, consider scheduling a general eye screening to determine which option is suitable for you.
Am I a suitable candidate for ReLEx SMILE or LASIK?
Suitability depends on factors such as your corneal thickness, refractive error, and overall eye health. In Singapore, LASIK is often recommended for a wider range of vision issues, while SMILE may be suitable for those with thinner corneas. For more questions or concerns, feel free to contact us.
