What is ReLEx SMILE Pro?

ReLEx SMILE Pro (more commonly known as just SMILE) is a fairly recently developed outpatient laser surgical procedure used to treat the following:

Short-sightedness (myopia)
Long-sightedness (hyperopia) - NEW and available since November 2024
Astigmatism

In SMILE Pro, a small piece of tissue from within the cornea is removed to alter the shape of the cornea to improve the way light rays are focused on the retina.

SMILE Pro is less invasive than traditional LASIK as it doesn't require the creation of a large flap hence it is more suitable for athletes. It is the preferential treatment for military pilots in some countries.

SMILE Pro is the improved version of SMILE which allows for faster treatments resulting in fewer complications and more comfortable experience for patients.

SMILE Pro® is only available through the Zeiss Visumax® 800 system

How is ReLEx SMILE Pro performed?

Here is what to expect:

You will be awake during the surgery and no sedation is necessary.

The procedure is generally a comfortable experience with minimal pain.
The eye is first numbed with anaesthetic eye drops.
The procedure involves the use of a single laser platform i.e the femtosecond laser.
A small piece of tissue created by the laser called the cornea lenticule is removed through a small incision (wound) on the cornea. The result of removing this lenticule is to flatten the cornea in the case of short-sightedness or make it more rounded in the case of astigmatism. This changes the focusing power of the cornea and improves your vision.
There is no cornea “flap” unlike in LASIK
The cornea wound will self-seal without the need for stitches
It takes generally 15-20 minutes to perform SMILE in both eyes

Am I a Good Candidate for SMILE Pro Surgery?

Not everyone can have SMILE or will benefit from it. Dr Au and his team will advise you accordingly.

Generally, in order to undergo SMILE surgery in Australia, you should:

Be at least 21 years of age
Not be pregnant
Be free of other eye diseases
Fulfil certain criteria with regards to cornea thickness, cornea shape and refractive error (degree). Patients with thin or irregular corneas, severe dry eye, cataract, glaucoma, uncontrolled diabetes, rheumatoid arthritis and other collagen vascular diseases are unsuitable for SMILE.

Most importantly, you must have realistic expectations about the outcome of the procedure, and be willing to accept the potential risks associated with it. Fortunately, SMILE is very safe, and the results excellent, and most patients are extremely happy with how the procedure has changed their lives.

What to Expect after ReLEx SMILE Pro

Here are important points to note:

Visual recovery after SMILE Pro is not instantaneous.
You will find that your eye sight is still foggy immediately after SMILE Pro. The vision usually improves gradually over the next few days. By the next day, you will be able to see well enough to perform most of your daily activities, but stabilization of vision may take several weeks.
When the effect of the anaesthetic eye drops wears off, some patients may experience pain, tearing, burning sensation, scratchiness and / or difficulty opening their eyes, the severity of which varies from patient to patient. These symptoms usually disappear after 6-8 hours. Most patients find the discomfort mild and bearable.
Healing after SMILE Pro is usually comfortable as the laser removes tissue from the inside of the cornea rather than from the more sensitive surface of the cornea.
You will be prescribed antibiotic and steroid eye drops as well as artificial tears to keep the eyes moist.

Overall, the surgery and post-surgery recovery, like LASIK, is a pleasant experience for most patients.

Most patients are able to return to work a day or two after.

Stabilization of vision varies. For some patients, it may take several weeks or a few months.

What Side Effects, Risks and Complications Should I be Aware of?

Like any other surgery, SMILE Pro has side effects that you need to know about and carefully consider before deciding on having the surgery. Fortunately, SMILE Pro is a very safe procedure and most of the side effects are mild and temporary. These include dry eye, fluctuating vision, hazy vision, haloes and glare in a dim environment and light sensitivity. Over- and under-correction may also occur, and a “top up laser” procedure called “enhancement” may be required in some cases. Serious side effects that can result in loss of vision are extremely rare, and these include severe inflammation, infection and corneal ectasia (weakening and thinning of the cornea).

An Important Point to Note:

SMILE Pro is technically more difficult to perform than LASIK eye surgery, and occasionally problems with the creation and removal of the cornea lenticule can occur during surgery. If this occurs, the doctor may choose not to complete the SMILE Pro treatment. This is uncommon, but it is very important to choose an experienced SMILE surgeon to perform the procedure, as adequate handling of such problems during surgery comes with experience.
SMILE Pro cannot correct presbyopia, the age-related loss of near vision due to a loss of the auto focusing power of the eye. With or without SMILE, most patients will require glasses for reading after the age of 45. PRESBYOND® LASIK would be the treatment of choice in this situation. Some LASIK surgeons offer a vision correction method called monovision (limited by laser technology) which leaves one eye fixed for close work at a certain distance(typically 50cm or 66cm away), while the other eye is fixed for distance vision. Monovision works well for some patients but some are unable to tolerate it, stereoacuity (3D vision) is also compromised.

Is LASIK or SMILE Pro Better for Me?

Both LASIK and SMILE Pro are safe and excellent laser vision correction procedures. Each procedure has its inherent advantages. Visual recovery and stabilization from LASIK is generally faster, but SMILE Pro, being a “flap-free” procedure may be more suitable for patients involved in high impact sports and other vocations.

Dr Au has experience performing both LASIK and SMILE Pro and based on your profile and needs, he will be able to best advise you on which procedure is better.
