What is Smile eye surgery?
SMILE eye surgery stands for small incision lenticule extraction and is a refractive procedure. SMILE helps treat many refractive errors, including myopia (nearsightedness), hyperopia (farsightedness), presbyopia (due to aging of the eye), and astigmatism.
What is Smile?
Surgical Therapy Small incision lenticule extraction (SMILE) is a relatively new refractive procedure designed to treat a multitude of refractive errors such as myopia, hyperopia, presbyopia, and astigmatism.
How much does smile cost per eye?
Cost of SMILE surgery. Most U.S. refractive eye surgeons charge approximately the same price for SMILE laser vision correction as they do for all-laser custom LASIK surgery — somewhere in the range of $2,000 to $3,000 per eye.
What is Smile in LASIK?
SMILE is an acronym for small incision lenticule extraction. In LASIK, a large opening is required to enable the excimer laser to reshape the underlying cornea.
How long does SMILE eye last?
The Benefits of SMILE Eye Surgery The SMILE procedure takes ten minutes or less. In some cases, SMILE can be used to correct higher levels of nearsightedness as compared to LASIK Eye surgery. Quick recovery: patients are allowed to wear makeup, exercise, and drive the day following the SMILE procedure.
What is the SMILE eye procedure?
The SMILE (Small Incision Lenticule Extraction) procedure involves reshaping the cornea by removing a small lens (lenticule) from the central corneal layer. The process uses a femtosecond laser and extracts the lenticule through four small incisions on the corneal surface.
Is SMILE as effective as LASIK?
SMILE and LASIK (laser-assisted in-situ keratomileusis) are both safe and effective options for laser vision correction. These are similar laser vision correction procedures in that they both correct the patient's refractive error by reshaping their cornea.
What is SMILE eye surgery vs LASIK?
Differences Between LASIK & SMILE LASIK treats all refractive errors. SMILE treats myopia with or without astigmatism, but not farsightedness or astigmatism by itself. LASIK requires a flap to be cut in the cornea, so the excimer laser reaches the inside of this part of your eye.
Does SMILE cost more than LASIK?
The majority of refractive eye surgeons in the United States charge similar rates for both LASIK and SMILE eye surgery — between $2000 and $3500 per eye is the common range of costs.
Is SMILE eye surgery painful?
During LASIK or SMILE, patients do not feel pain. There is a brief moment lasting 30-40 seconds when the LASIK flap or SMILE lenticule is being created where patients feel a sensation of pressure on the eye. Some describe this as feeling similar to wearing a tight pair of swimming goggles.
Is SMILE surgery FDA approved?
FDA approves VisuMax Femtosecond Laser to surgically treat nearsightedness. The U.S. Food and Drug Administration today approved the VisuMax Femtosecond Laser for the small incision lenticule extraction (SMILE) procedure to reduce or eliminate nearsightedness in certain patients 22 years of age or older.
Is SMILE better than PRK?
Kling. LASIK involves cutting a flap in the anterior cornea, the strongest part of the cornea. Therefore, it is no surprise that we found post-SMILE human corneas to be 47% stronger than post-LASIK human corneas. But we also know that post-PRK corneas are stronger than post-LASIK corneas.
Can you do SMILE surgery twice?
A second procedure is necessary if refractive errors were not corrected during LASIK. If a second procedure has been deemed necessary, another flap will be created. Most surgeons won't perform a second LASIK procedure unless it's 5-10 years after LASIK.
How good is vision after SMILE?
After a SMILE eye surgery, it is common and expected to have blurry vision for a few days. Typically, your vision will begin to progressively get clearer over a few weeks or months.
How long is SMILE surgery recovery?
SMILE laser surgery recovery is a fast process that gets you back on your feet in no time. You can get back to work within 24 hours and back to daily activities within a week. You should see full improvement within a week of your procedure.
Can I wear contacts after SMILE?
You can start wearing eye makeup and do beauty parlor treatments after 15 days, and after having checked with our doctor on your post treatment visit. Cosmetic contact lenses can be worn after consultation with your surgeon, but are usually allowed a month later.
Is SMILE less invasive than LASIK?
SMILE is a less invasive procedure than LASIK, offering many benefits, according to a 2019 article published in Review of Ophthalmology.
Is SMILE better than PRK?
Kling. LASIK involves cutting a flap in the anterior cornea, the strongest part of the cornea. Therefore, it is no surprise that we found post-SMILE human corneas to be 47% stronger than post-LASIK human corneas. But we also know that post-PRK corneas are stronger than post-LASIK corneas.
How long does it take for vision to stabilize after SMILE?
It was observed that approximately 10% eyes still had an IRG score between 1 and 2 at the end of 3 months, suggesting that it may take 3 months or more for the healing of the interface and hence complete stabilization of vision after SMILE.
What happens after SMILE laser eye surgery?
Within a couple of days after SMILE, you should be back to your routine life. You may notice improvements in your vision immediately following your procedure, as well. Although, your eyesight will continue to improve for the next few weeks. Immediately following SMILE, you will need someone to drive you home.

What is the purpose of a suction ring?
The eye surgeon will place an eyelid holder on the eye to prevent blinking. A suction ring raises and flattens the cornea and helps maintain the eye in place. The eye surgeon will then use the laser to form a lenticule (a disk-shaped piece of corneal tissue) below the eye’s surface.
What is the laser used for Smile?
A possible laser used during the procedure is the VisuMax femtosecond laser. Eye drops will be administered to numb the eyes.
How small is the incision for LASIK?
For example, the procedure makes a small incision (2-3 mm) in the eye, keeping corneal nerve severance at a minimum. This contrasts with LASIK, which includes the cutting of a corneal flap.
When was Smile approved?
The Food and Drug Administration (FDA) in the United States approved SMILE for refractive myopic corrections in 2016 and compound myopic astigmatism in 2018. This type of refractive surgery has proven popular against other laser vision correction procedures.

Ophthalmology clinic location. Screening eye exam. On average, individuals may spend between $2,000 and $4,000 for SMILE eye surgery.
What do ophthalmologists do before eye surgery?
Before the actual procedure, the ophthalmologist will perform some eye exams to assess vision and take measurements. Some of these measurements can include pupil size, cornea thickness, and much more related to the cornea’s surface.
What is Smile laser?
ReLEx® SMILE is an innovative form of keyhole laser eye surgery which can correct vision for people with higher degrees of short-sightedness. SMILE stands for Small Incision Lenticule Extraction, and is a bladeless procedure which is minimally invasive. SMILE eye surgery is suitable for people with or without astigmatism, and it can be a great alternative to the more well-known LASIK and LASEK treatments.
How does Smile laser work?
The procedure works as follows: Firstly, your surgeon will administer anaesthetic eye drops to numb the eye, ensuring that the treatment is completely painless.
How long does it take for Smile Eye Surgery to work?
By comparison, LASIK typically gets results after around 24 hours, whilst LASEK can take a few days.
How long does Smile laser eye surgery take?
The whole procedure is completed in less than 15 minutes for both eyes, with the laser only being used for a small proportion of this time. The benefits of SMILE laser eye surgery. Now you know more about SMILE and how it works, let’s take a look at the benefits of this treatment and how it differs from other types of laser eye surgery.
What is the purpose of VisuMax laser?
Next, the Carl Zeiss VisuMax laser is used to place a number of pulses on the cornea’s centre with extraordinary precision. The pulses from the laser then create tiny bubbles, less than one-hundredth of the width of a human hair. These bubbles create the outline for the tissue that needs to be removed.
How long does it take for your eyes to go back to normal after Smile?
After the SMILE treatment, vision is typically 80% better within a few hours , and reaches 100% improvement within a few weeks, according to trials. One thing you do need to be aware of is that, while recovery is quick, there is also the chance that your vision will temporarily be slightly blurry after the operation.
Is Smile eye surgery risky?
No chance of flap complications – One of the main differences between SMILE eye surgery and other options such as LASIK is that no flap is created during the SMILE procedure. This means there is no risk of complications such as the flap folding or moving, and it also means the eye is more comfortable after the procedure has taken place.
When Is SMILE Used?
A new type of laser refractive eye surgery called small incision lenticule extraction, or SMILE, treats myopia, or nearsightedness.
How Much Does SMILE Cost?
Refractive Surveys (2019), the cost of SMILE has decreased from about $4,290 in 2016 to $2,361 in 2019. This can change based on where you live, what your individual ophthalmologist charges, and where their practice is located. However, you can expect to pay between $2,000 and $3,000 per eye for SMILE. This is similar to the cost of LASIK and related laser-guided eye surgeries.
How does a laser help the cornea?
Using a laser, your ophthalmologist will create a lenticule in your lens and then remove it, so the cornea flattens. Light is then refracted more clearly onto your retina.
What is a small incision lenticule extraction?
Small incision lenticule extraction (SMILE) is a procedure designed to treat mild myopia with or without associated mild astigmatism. Myopia is the most common refractive error, caused by a misshapen cornea and lens. ( Learn More)
Why is my eye blurry?
People who have a problem with the cornea and lens may not get enough light refracted through the eye, or the light may hit in a way that the brain processes it as a blurry or doubled image. Nearsightedness means your brain can process images of close-up objects correctly, but far objects will appear blurry.
How long after cornea surgery can you see?
You should be able to see the next day, although your vision may be a little blurry for up to a few weeks after the operation as your cornea reshapes and heals. You should avoid any activities that might get particles in your eyes, including swimming, for a few days, until your ophthalmologist clears you. You should be able to return to low-impact normal daily routines one or two days after the procedure.
What is Smile laser surgery?
SMILE is a simple, fast, and low-impact laser surgery. While you will not spend a lot of time in the operating room, you will need to work with your ophthalmologist to plan the operation and understand what happens after it is complete.
What is SMILE?
Small Incision Lenticule Extraction with SMILE is the most recently developed type of laser eye surgery. It’s a minimally invasive procedure that can correct various vision impairments such as nearsightedness and astigmatism.
What is a lentil extraction?
Lenticule Extraction is the latest advancement of laser vision correction and SMILE has been available since 2011. The technique is known and recognized by medical trade associations related to refractive laser eye surgeries.
How wide is the corneal incision?
Once the eye is held stationary, the laser creates a lenticule within the stroma (an inner sub-layer of the cornea) and creates an access incision on the corneal surface that is less than 4mm wide.
How to do laser eye surgery?
This is done with a contact glass, which is placed gently on the eye and connected to the laser device. You may feel slight pressure during this step. Once the eye is held stationary, the laser creates a lenticule within the stroma (an inner sub-layer of the cornea) and creates an access incision on the corneal surface that is less than 4mm wide.
How long does it take for a laser to work?
It takes an average of 23 seconds for the laser to create a small lens-shaped piece of corneal tissue (called the lenticule) inside the cornea. The surgeon then removes the lenticule through a small incision outer part of the eye. This reshapes the cornea and corrects the refractive error.
What is Smile laser?
SMILE is running on a femtosecond laser to reshape the cornea. This femtosecond laser is an extremely short-pulsed, near infrared laser often also used to create a LASIK flap. The laser's high peak intensity over a very short pulse duration (within a few femtoseconds of time) allows it to create micro-precision single holes (bubbles) that forms together cuts or planes in the corneal tissue without affecting the surrounding tissue.
Why is corneal stability supported?
Maintaining the corneal stability is supported, because the entire upper layers of the cornea are virtually unaffected.
What is FLEx in LASIK?
Starting in 2007, an intrastromal lenticule method was reintroduced as an alternative to LASIK called Femtosecond Lenticule Extraction (FLEx) intended for patients with extreme myopia. After improvements to scan modes and energy parameters, improved visual recovery times were noted, with refractive results similar to LASIK. Following the implementation of FLEx, a procedure called small incision lenticule extraction (SMILE) was developed, involving a small 2-3 mm incision used to allow for extraction of the whole corneal lenticule without the need to create a flap.
How is the Smile procedure performed?
During the SMILE procedure, the patient is raised to the contact glass of the femtosecond laser and suction ports are activated to keep the patient's eye fixated in the correct position while the lenticule is created . The lower interface of the intrastromal lenticule is created first (using an out-to-in direction with the laser to maximize the time without blurring the patient’s central vision), followed by the upper interface of the lenticule (using an in-to-out direction), known as the cap, and finally a 2–3 mm tunnel incision (usually supero-temporal) that links the cap interface to the corneal surface. To avoid any undesirable effects in the cornea such as haziness, the two interfaces (lower and upper) are created from the endothelial side of the cornea to the epithelial side. The patient is then moved to the surgical microscope for the lenticule separation and extraction part of the procedure. The layers of the lenticule are outlined and the lenticule is removed from the cornea using a pair of retinal micro-forceps, or can be extracted directly from within the pocket with the latest versions of the lenticule stripper, one of many instruments being developed for the SMILE procedure specifically.
What is a small incision lenticule extraction?
Small incision lenticule extraction (SMILE) is a relatively new refractive procedure designed to treat a multitude of refractive errors such as myopia, hyperopia, presbyopia, and astigmatism. The procedure involves using a femtosecond laser to create a corneal lenticule which is extracted whole through a small incision without the use of an excimer laser. It is reported to achieve effects similar to laser-assisted in situ keratomileusis (LASIK) with excellent post-operative outcomes.
How small is the incision for corneal nerve severance?
Because a small incision (2-3 mm) is used in place of an entire flap, corneal nerve severance is minimal in comparison to LASIK. This coincides with the decreased occurrence of post-operative dry eye and studies have indeed shown an increase in nerve reinnervation after treatment.
How is a lenticule removed from the cornea?
The layers of the lenticule are outlined and the lenticule is removed from the cornea using a pair of retinal micro-forceps, or can be extracted directly from within the pocket with the latest versions of the lenticule stripper, one of many instruments being developed for the SMILE procedure specifically.
What are the complications of Smile?
Studies using SMILE found epithelial abrasions, small tears at the incision, and perforated caps in few cases, however, none of these patients had late visual symptoms. The loss of suction during the femtosecond laser portion of the procedure is one of the primary complications with SMILE, and seems to be a difficult topic to define care that applies to most or all cases. While noted to be very infrequent, one study showed the majority of cases in which suction loss occurred were able to be reapplied in the same setting (81.8%).
Is Smile a good alternative to lasik?
The SMILE procedure, while still in its early stages, seems to be a promising alternative to LASIK in some cases. Given its flapless technique and results that appear to be similar to LASIK, it may offer the same correctional abilities with the potential benefits of faster recovery of post-op dry eye, quicker reinnervation of corneal nerves, and biomechanical advantages. After clinical trials are completed for SMILE and pending its approval, this procedure may be an upcoming option for some patients, due to its minimally invasive technique and promising outcomes.
