Introduction: LASIK and SMILE at a Glance
LASIK (Laser-Assisted in Situ Keratomileusis) and SMILE (Small Incision Lenticule Extraction) are today’s most advanced vision correction procedures.
Both utilize state-of-the-art laser technology to reshape the cornea, correcting refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
In LASIK, a thin flap is created on the cornea’s surface, which is lifted to expose the underlying corneal tissue. The surgeon then uses an excimer laser to reshape the shape of the cornea, allowing light to focus properly on the retina. Once the desired corneal reshaping is achieved, the flap is repositioned, and it adheres naturally without the need for stitches.
The SMILE operation, on the other hand, is a newer procedure that requires a smaller incision. A femtosecond laser creates a small lenticule (a thin disc of corneal tissue) within the cornea, which is then removed through the small incision. Removing this lenticule reshapes the shape of the cornea, leading to the correction of refractive errors.
Embracing Laser Eye Surgery: The Increasing Demand for Vision Correction Through Advanced Technology
The growing popularity of laser vision correction can be attributed to its numerous benefits, such as quick recovery times, minimal discomfort, and significantly improved vision. LASIK and SMILE surgery has gained worldwide recognition and has been performed on millions of patients, allowing them to reduce or eliminate their dependence on glasses or contact lenses.
As an expert ophthalmologist, it is essential to educate patients about the differences between LASIK and SMILE surgery and guide them toward making an informed decision to correct their vision first. While both procedures have their merits, LASIK has been around longer, has a proven track record, and offers several advantages over SMILE. In this blog, I will explore the top 10 reasons you should consider LASIK over SMILE surgery (small incision lenticule extraction) for your vision correction journey.
LASIK: A Proven Track Record
The History and Success of LASIK
LASIK has been performed for more than 25 years, with its roots dating back to the early 1990s. Dr. Ioannis Pallikaris, a Greek ophthalmologist, is credited with developing the modern LASIK technique, which combined a microkeratome (a precision surgical instrument) to create a corneal flap with excimer laser ablation to reshape the cornea.
Over the years, LASIK has undergone significant advancements, incorporating new technologies like femtosecond lasers, wavefront-guided treatments, and topography-guided treatments to improve the procedure’s precision, safety, and overall outcomes. These advancements have made LASIK one of the most successful and popular vision correction procedures globally.
The Vast Number of Satisfied Patients
LASIK has been performed on millions of patients worldwide, and its high success rate speaks for itself. According to numerous clinical studies and patient satisfaction surveys, over 96% of LASIK patients are satisfied with their results. This impressive satisfaction rate can be attributed to the procedure’s ability to provide excellent visual outcomes with minimal side effects and complications.
One key reason behind LASIK’s high patient satisfaction rate is its ability to treat a wide range of refractive errors. From mild to moderate myopia, hyperopia, and astigmatism, LASIK can effectively address various visual issues and correct refractive errors, allowing patients to enjoy clear vision without needing glasses or contact lenses.
In summary, LASIK’s proven track record and many satisfied patients make it a reliable and effective option for those considering vision correction surgery. As we explore the top reasons to choose LASIK over SMILE, you will gain a deeper understanding of the unique advantages LASIK offers in various aspects of the vision correction journey.
Visual Outcomes: Clarity Matters
Comparing LASIK and SMILE (Small Incision Lenticule Extraction) Vision Results
LASIK and SMILE have demonstrated excellent visual outcomes, allowing patients to achieve clear vision without needing glasses or contact lenses. However, LASIK has a slight edge regarding overall visual clarity. Studies have shown that LASIK patients tend to achieve better postoperative vision quality, particularly in contrast sensitivity and night vision, compared to SMILE patients.
Higher-Order Aberrations and LASIK’s Edge
Higher-order aberrations (HOAs) are complex optical imperfections that can degrade the quality of vision, causing issues like glare, halos, and starbursts. LASIK’s edge over SMILE in terms of visual outcomes can be attributed to its ability to manage HOAs better. Wavefront-guided LASIK, in particular, can measure and treat HOAs, improving vision quality and reducing nighttime visual disturbances.
Faster Recovery Time With LASIK
LASIK offers a faster recovery time than SMILE, with patients typically experiencing significant vision improvement within hours and resuming normal activities within a day or two. The quicker recovery is due to LASIK’s technique, where the repositioned corneal flap acts as a natural bandage, promoting rapid healing and minimal discomfort. In contrast, SMILE patients may take up to a week or more for complete visual recovery.
Treating Astigmatism: LASIK’s Superior Flexibility
Compared to SMILE, LASIK offers a more comprehensive solution for a broader range of refractive errors, including astigmatism. It can effectively treat mild to moderate astigmatism and provides customizable treatment options, such as wavefront-guided and topography-guided techniques, to enhance visual outcomes. In contrast, SMILE laser eye surgery is limited in treating astigmatism, addressing only lower levels of the condition and lacking the customization options available with LASIK. This makes LASIK laser eye surgery a more versatile choice for patients with various refractive errors, particularly astigmatism.
Customizable Treatment: Personalized LASIK
LASIK’s ability to offer personalized treatments tailored to each patient’s unique eye characteristics is a significant advantage. Wavefront-guided LASIK employs advanced technology to measure optical imperfections, including higher-order aberrations, and create a customized treatment plan, resulting in improved visual outcomes such as contrast sensitivity and night vision. Topography-guided LASIK, meanwhile, utilizes corneal surface mapping to identify surface irregularities, allowing the surgeon to develop a custom treatment plan addressing these specific issues. This technique is particularly beneficial for patients with corneal irregularities or those who have undergone previous eye surgeries.
LASIK’s Touch-Up Options
The Possibility of Enhancements After LASIK
Another advantage of LASIK surgery is the possibility of postoperative enhancements, also known as touch-ups. Patients may sometimes require minor adjustments to fine-tune their vision after the initial LASIK procedure. These enhancements can be performed quickly and easily, allowing patients to achieve their desired visual clarity.
SMILE’s Limitations in Providing Postoperative Adjustments
SMILE’s technique of removing a small lenticule through only a small incision a tiny, small incision, makes it more challenging to perform postoperative enhancements. If a patient requires a touch-up after SMILE eye surgery, they may need to undergo a LASIK procedure to achieve the necessary adjustments. This limitation can make the overall vision correction process more complicated and potentially more expensive for SMILE eye surgery patients.
Accessibility: More Surgeons Offer LASIK
The Widespread Availability of LASIK Providers
With its proven track record and extensive history, many eye surgeons worldwide offer LASIK eye surgery. This widespread availability ensures that patients can easily access skilled and experienced LASIK eye surgery providers who have honed their techniques over years of practice.
In contrast, SMILE eye surgery is a newer procedure with fewer providers globally. While the number of SMILE eye surgery providers is growing, it still falls short of LASIK’s extensive network of surgeons. This limited availability can make it more challenging for patients to find a skilled SMILE surgeon or may require them to travel to receive the procedure.
Long-Term Patient Satisfaction: Trusting the LASIK Legacy
Survey Data on LASIK Patient Satisfaction
Over the years, numerous studies and surveys have consistently shown high patient satisfaction rates with LASIK. With an overall satisfaction rate of over 96%, LASIK has maintained a strong reputation for delivering excellent visual outcomes and meeting most patients” expectations.
Comparing Long-Term Satisfaction Rates Between LASIK and SMILE
While SMILE eye surgery has also demonstrated high patient satisfaction rates, the long-term data on SMILE is limited due to its relative novelty. LASIK’s long history and extensive clinical data make it a more reliable option for those seeking long-term satisfaction with their laser vision correction or enhancement procedure.
Dry Eye Syndrome: LASIK’s Technological Advancements
The Role of Femtosecond Laser Technology in Reducing Dry Eye Risks
One common concern with laser vision correction procedures is the potential for dry eye syndrome. Advancements in LASIK technology, such as using femtosecond lasers, have helped reduce the risk of postoperative dry eye. By creating a more precise corneal flap, femtosecond lasers minimize the disruption of corneal nerves, leading to a reduced incidence of post-op dry eye.
A Comparison of Dry Eye Prevalence Between LASIK and SMILE
While SMILE is often touted as being minimally invasive and causing much less risk of dry eye due to the smaller incision, studies have shown that the prevalence of dry eye after LASIK and SMILE is comparable. Both procedures have similar dry eye risks, but LASIK’s technological advancements provide additional reassurance for patients concerned about less risk of this side effect.
The Cost Factor: Comparing Affordability
The Average Cost of LASIK Versus SMILE
In general, the cost of LASIK is more affordable than SMILE eye surgery. While prices can vary depending on the surgeon, technology, and location, LASIK’s widespread availability and competition among providers often result in more competitive patient pricing.
