What Is Spherical Number for Smile Pro Eye Surgery?

In the ever-evolving landscape of vision correction, SMILE Pro stands as a trailblazer, reshaping the narrative of laser eye surgery. This groundbreaking procedure, an evolution of the proven SMILE technique, harnesses cutting-edge technology and precision to address myopia and myopic astigmatism with unparalleled accuracy. At the core of SMILE Pro lies a pivotal metric—the Spherical Number.

But what exactly is the spherical number for this procedure, and how does it affect the outcome? Let’s dive into some details.


Understanding SMILE Pro Eye Surgery

SMILE (Small Incision Lenticule Extraction) Pro eye laser surgery is a minimally invasive procedure that uses a femtosecond laser to create a lenticule inside the cornea. This lenticule is then removed through a small keyhole incision, reshaping the cornea and thus correcting the refractive error of the eye, resulting in sharp and clear vision. This procedure has gained popularity due to its quick recovery time and minimal discomfort for patients.

But what sets SMILE Pro apart from other laser vision correction procedures like LASIK or PRK? The answer lies in the spherical number used in this procedure.


Demystifying the Spherical Number in SMILE Pro

The Spherical Number or spherical aberration is a measurement of how light rays converge or diverge as they pass through the eye’s optical system. In simpler terms, it refers to the shape of the cornea and its ability to focus light properly on the retina.

In the realm of laser eye surgery, the degree of myopia, hyperopia, or astigmatism is measured in diopters. The spherical number represents the comprehensive correction needed to optimize vision, which can be positive or negative. A positive spherical number indicates hyperopia (farsightedness), while a negative number indicates myopia (nearsightedness).

In the case of SMILE Pro eye surgery, the spherical number determines the shape and size of the lenticule that will be created within the cornea. This level of precision is vital for accurately correcting the spherical number and achieving optimal visual outcomes for individuals with refractive errors.

Notably, SMILE Pro excels in addressing myopia within the expansive range of -0.5 to -10 diopters spherical equivalent ( = sphere + (cylinder/2), showcasing its adaptability to a diverse spectrum of refractive errors.

SMILE Pro corrects myopia up to -10 diopters and effectively treats myopic astigmatism up to -5 diopters. This distinctive capability positions SMILE Pro as the preferred choice for individuals with multifaceted refractive needs.


How is the Spherical Number Determined?

Before undergoing SMILE Pro eye surgery, a comprehensive eye examination is conducted to determine the patient’s spherical number. This involves various tests such as refraction, corneal topography, and pachymetry. These tests help to map the curvature of the cornea, measure its thickness, and identify any irregularities that may affect the visual outcome.

Based on these results, the spherical number is calculated and used to create a personalized treatment plan for the patient. This ensures that the lenticule is of the correct size and shape, leading to optimal correction of refractive errors.


How Does Spherical Number Affect SMILE Pro Eye Surgery?

Unlike traditional LASIK surgery, which requires the creation of an 18-20 mm flap on the corneal surface, SMILE Pro creates a small lenticule inside the cornea. This procedure allows for better control and customization of the spherical number, resulting in more precise correction of visual errors. The accuracy of this measurement directly affects the amount of tissue that will be removed from the cornea and the overall visual outcome.

Also, the use of advanced femtosecond laser technology and the keyhole incision allows for a more precise and customizable treatment. This results in minimal tissue removal and preservation of the corneal integrity, leading to faster recovery time and reduced risk of dry eye syndrome compared to other procedures.


The Benefits of Spherical Number Control

By offering better spherical aberration control than LASIK, SMILE Pro can provide improved visual outcomes for patients with higher-order aberrations and spherical aberration. This means that even individuals with more complex refractive errors can benefit from this procedure.

Moreover, the larger optical zone created by SMILE Pro allows for better night driving vision compared to LASIK surgery. This is especially beneficial for those who drive at night regularly.


Beyond Numbers: Prioritizing Comfort and Recovery

Beyond the numerical facets, SMILE Pro prioritizes patient comfort and rapid recovery. The laser segment of the procedure concludes in less than 10 seconds, and the technology is meticulously designed for an exceptionally comfortable experience. With an impressive 99% of patients able to resume work the very next day after the procedure, SMILE Pro guarantees a swift return to regular activities.


Embracing Clarity with SMILE Pro

In conclusion, the Spherical Number emerges as the linchpin of SMILE Pro, guiding the nuanced correction of myopia and myopic astigmatism. This advanced procedure takes into account each individual’s unique refractive error and uses precise measurements to achieve optimal visual outcomes.

With avant-garde technology, minimal invasiveness, better control over spherical aberration, and a steadfast commitment to patient comfort, SMILE Pro stands as a transformative force in the realm of laser eye surgery. Choosing this groundbreaking procedure signifies embracing a future where vision is not merely corrected but optimized with unparalleled precision and care—a testament to the ongoing pursuit of clarity in the world of ophthalmic innovation.

Experience the freedom from glasses and contact lenses and welcome the era of clear and impeccable vision with SMILE Pro eye surgery. Join the ever-growing community of delighted patients who have achieved unparalleled clarity and sharpness in their vision through SMILE Pro.
