HealthUnderstanding SMILE Eye Surgery

Have you ever considered laser eye surgery? If so, you’ve probably come across different procedures, including SMILE eye surgery.

This innovative approach is gaining popularity, but like any medical procedure, it’s not without its side effects and considerations.

SMILE eye surgery, while often more expensive, has been reported to cause less postoperative dryness compared to its LASIK counterpart.

However, potential side effects such as temporary starbursts and halos, or even inflammation, should not be overlooked.

It’s crucial to understand the risks, benefits, and factors that influence the longevity of the results before making a decision.

In this article, we’ll delve deeper into what SMILE eye surgery is, its pros and cons, and what to expect during the recovery process. Stay tuned if you’re considering this procedure or simply curious about the world of laser eye surgery.

Understanding SMILE Eye Surgery

As your journey of exploring laser eye surgery options continues, it’s advantageous to delve deeper into the specifics of SMILE eye surgery and see how it compares to the well-known LASIK.

The Basics of SMILE Procedure

SMILE, the acronym for SMall Incision Lenticule Extraction, provides a less intrusive method of correcting specific eye defects, notably myopia (nearsightedness) and astigmatism.

This surgical procedure works by reshaping your cornea, the clear front surface of your eye. It achieves this by using a femtosecond laser, the same type used in LASIK, to create a disc-shaped tissue, also termed a lenticular, within your cornea.

The lenticular, corresponding to the refractive error you’re experiencing, is then extracted out via a tiny incision. The removal of this lenticular allows your cornea to reshape itself, thus correcting the refractive error and improving your vision.

Due to its efficient mechanism, SMILE potentially reduces many of the complications tied to other types of laser eye surgeries, as it completely dodges the need for creating a flap, a critical component in the LASIK procedure.

Comparing SMILE With LASIK

While both SMILE and LASIK are effective at treating refractive errors, distinguishing characteristics separate the two.

As outlined, the SMILE procedure incorporates only one laser (femtosecond) and avoids the creation of a flap, compared to LASIK which necessitates a flap creation and use of two lasers (femtosecond and excimer).

The apparent outcome of SMILE’s distinctive procedure is the reduced risk of dry eyes post-surgery, a common complaint from LASIK patients. Furthermore, SMILE’s smaller incision lends itself to a potentially lower susceptibility to post-operative complications.

Despite these advantages, it’s important to remember that no surgical procedure is without its risks or potential side effects. It’s reported that conditions such as corneal ectasia (warping of the cornea) could arise from the SMILE procedure.

Moreover, while studies depict close similarities in vision correction outcomes between SMILE, LASIK, and PRK, the final choice typically depends on each patient’s unique eye condition and lifestyle needs.

Therefore, consulting with experienced professionals, such as those found in a leading eye clinic Houston, can provide personalized advice on which procedure would yield the best results for your situation.

Benefits and Risks of SMILE Eye Surgery

Advantages of Choosing SMILE

SMILE laser eye surgery offers several impressive advantages. Based on clinical studies, the procedure boasts a high success rate, 99% of patients achieve 20/40 vision or better, and over 90% hit the 20/20 mark or better.

When considering vision issues, SMILE produces results that are equivalent to those of LASIK, yet it avoids flap creation, a step in the LASIK process known to introduce complications potentially.

The removal of this step not only results in fewer infections, but SMILE patients also report less occurrence of dry eye symptoms, making this a preferred choice for those suffering from this condition.

Interestingly, the method of action in SMILE reduces the risk of a common post-LASIK complication known as corneal ectasia.

Moreover, SMILE surgery consists of a less invasive approach, which speeds up the recovery time.

But remember, while this treatment can dramatically improve vision, it’s crucial to receive a professional assessment to ascertain whether you are a suitable candidate for this procedure.

Potential Complications and Risks

While SMILE presents numerous advantages, it’s essential to understand the associated risks. First, this procedure may trigger under-correction in patients with astigmatism—this occurs in about 11% of these cases.

In connection to the optical system, SMILE technology lacks iris recognition capability, a useful feature of the 4th-generation wavefront-guided LASIK.

This missing element might cause less accurate vision correction since it would be more challenging to maintain the targeted laser beam focus when the patient’s eye moves during the procedure.

Other potential drawbacks, including dry eye symptoms and rare corneal complications related to lenticule removal, remain low. But notably, SMILE may not be the right solution for everyone.

Patients with thin corneas, presbyopia, or certain corneal abnormalities might not get green-lighted for this treatment.

For these reasons, and to mitigate all potential risks, a thorough evaluation by an ophthalmologist becomes imperative before deciding on SMILE eye surgery.

Candidacy and Preoperative Considerations for SMILE

When considering any ocular procedure, evaluating candidacy and gathering preoperative information are integral steps. This reality is not different for SMILE eye surgery.

Who Is an Ideal Candidate?

Ideal SMILE eye surgery candidates must meet certain criteria. First, one must be at least 18 years old, indicating a higher probability of ocular maturity.

It’s also vital for your vision stability, with a wave of sight prescription changes not observed in the past year.

Eye health is another criterion, specifically in the realm of corneas. For those who do not know, a healthy eye and cornea are prerequisites.

Moreover, the level of myopia or nearsightedness between -1 and -10, accompanied by astigmatism less than or equal to 3 diopters, fits well within this eligibility constraint.

Understanding these requirements and assessing whether they relate to your situation forms a crucial step in the initial stages of planning for SMILE eye surgery.

Preparing for SMILE Eye Surgery

Moving on to surgery preparation, a presurgery appointment precedes the main procedure. Eye evaluation forms an essential part of this consultation.

Here, surgeons examine to ensure you don’t host any prevision conditions or diseases that might hinder the surgery. Following the identification of a suitable candidate, precise plans to remove the lenticule from your eye ensue.

Measurements of your cornea’s curvature and thickness provide vital information for these plans. Furthermore, surgeons usually take utmost care to understand the medications or supplements you are currently taking.

In certain instances, there could be medications you may be recommended to stop in the run-up to the surgery, followed by an explanation of when the halt should kick in.

Modifications to your eating and drinking habits may also apply on the eve of the procedure, following advice from your healthcare provider.

Lastly, remember that the aftermath of the surgery restricts you from driving, so it’s recommended to have an adult friend or family assist with the commute.

This step marks the beginning of your journey with SMILE eye surgery, initiating the actualization of regaining sharp visuals, one that every eye clinic, including our hometown Eye Center in Houston, is proud to facilitate.

The SMILE Procedure Explained

Navigating through the world of vision correction can often be complex and full of jargon. To make things simpler, let’s delve into a clear, step-by-step understanding of the SMILE procedure and what you can expect during the process.

Steps Involved in SMILE Surgery

SMILE surgery, notably performed at renowned eye centers such as those in Houston, follows a precise and refined protocol.

  1. Eye Preparation: Initially, a qualified surgeon administers topical anesthesia on your eye’s surface to ensure comfort during the procedure.
  2. Lenticule Creation: Using a highly accurate femtosecond laser, the surgeon crafts a small lens-shaped piece of tissue, referred to as the lenticular, within the cornea. The surgeon calibrates the shape of this lenticular to correct the precise measure of your refractive error.
  3. Lenticule Extraction: The surgeon isolates and extracts the lenticular through a small incision, also made by the laser. This removal does not disrupt the surface of the eye but alters the cornea’s shape, thereby fixing the refractive error that causes your unclear vision.

Duration and What to Expect During Surgery

SMILE surgery fits into the hustle and bustle of everyday life, given its average duration is only around 15 minutes per eye. Since it’s an outpatient procedure, you can typically return to the comfort of your home shortly after.

During the procedure, you might feel a bit of pressure on your eye, but it’s generally painless. Immediately after the surgery, blurry vision is normal, but it remarkably improves over the next 24 to 48 hours.

As consultations at an eye clinic such as the ones in Houston are part of the process, you’ll receive detailed guidance on eye care post-surgery to expedite recovery and optimize visual outcomes.

As the procedure’s name indicates, “Small Incision Lenticule Extraction” provides a minimally invasive approach to vision correction.

Placing a priority on your comfort and visual acuity, SMILE surgery could indeed be a reason for you to smile when it comes to rectifying your refractive error.

Postoperative Care and Recovery

Postoperative care and recovery are critical in achieving the best outcome after SMILE eye surgery. It plays a critical role in helping your eyes heal without complications and reaching your optimal vision correction.

Immediate Post-Surgery Care

Immediately after SMILE eye surgery, expect to rest for a while at the eye clinic before going home. You’ll be given protective eye shields to wear to prevent accidental rubbing or pressure on your eyes.

These shields come in handy, especially during sleep. Avoid driving yourself home and arrange for someone to do this for you as your vision may still be blurry.

You may experience mild discomfort, itching, or a sensation of something in your eye. The good news, these symptoms are temporary and should improve within a few hours.

Use over-the-counter pain relievers to manage any discomfort but avoid rubbing your eyes to prevent dislodging the small incision made during surgery.

Postoperative appointments will be scheduled to check on the healing process. Remember, maintaining good eye hygiene and using prescribed eye drops can help mitigate risks of infection and inflammation.

Long-Term Outcomes and Vision Correction

The long-term outcomes of SMILE eye surgery are indeed promising. Most patients achieve vision correction within a few weeks to a few months post-surgery. It’s normal to have fluctuating vision during the first few weeks as your eyes adjust.

If you come across unexpected issues or concerns regarding your vision, inform your eye surgeon promptly. Some patients may require enhancement procedures due to under-correction, an instance whereby not enough tissue was removed during the initial procedure.

Remember that regular checkups at your eye center are essential, even after successful surgery. Such visits allow your eye surgeon to monitor your eyes’ health and ensure no complications arise.

SMILE eye surgery can give you the freedom from glasses and contact lenses you’ve been longing for. With proper postoperative care and routine eye clinic visits, the benefits of this innovative procedure can undoubtedly be enjoyed for a long time.


So, you’ve explored the ins and outs of SMILE eye surgery. It’s a game-changer, offering an alternative to LASIK with its minimally invasive approach and quick procedure time.

It’s crucial to remember the importance of preoperative preparations and postoperative care. Rest, protective shields, and avoiding rubbing your eyes are just a few steps to ensure a smooth recovery.
