Smile Eye Surgery High Myopia

Have you ever found yourself squinting to read a distant sign or searching for your glasses as soon as you wake up?

Nearsightedness, also known as myopia, affects millions of people. It’s only natural to desire clearer vision without relying on glasses or contacts.

Luckily, there’s a promising alternative to the well-established LASIK procedure called SMILE (Small Incision Lenticule Extraction). It’s particularly effective for correcting myopia with or without astigmatism.

However, when it comes to extremely high myopia, the decision becomes more complex.

Let’s dive into the current landscape of SMILE for high and extremely high myopia, exploring its benefits, limitations, and ongoing research.


The Allure of SMILE

SMILE offers numerous advantages compared to LASIK. By avoiding the creation of a corneal flap, it has the potential to reduce dry eye and post-operative discomfort. The use of a smaller incision also minimizes the risk of complications associated with flaps. Moreover, SMILE may provide improved night vision and better preservation of corneal tissue, which are both crucial factors for long-term eye health.


SMILE for Extremely High Myopia: A Work in Progress

While SMILE is effective for moderate to high myopia (up to -10 diopters), the situation becomes less clear for extremely higher prescriptions.

Research indicates favorable results for myopia up to 10 D, with patients experiencing improved vision and quality of life. However, concerns arise beyond this threshold and warrant further investigation in the future.


Challenges and Uncertainties

  • Under-correction and Regression:
    Extremely higher levels of myopia correction in SMILE can sometimes result in under-correction, meaning that your vision may not achieve the desired level of sharpness. Moreover, regression, which refers to a gradual reduction in the effectiveness of the correction over time, is more noticeable in cases of extremely high myopia. This may potentially require additional treatment.
  • Limited Treatment Range:
    At present, SMILE is FDA-approved for the treatment of myopia up to -10 D along with astigmatism up to -5 D. It may not be suitable or as effective for treating eyes with significantly higher levels of myopia or complex astigmatism using the current technology.
  • Corneal Stability:
    In cases of extremely high myopia, the cornea tends to be thinner. Removing more tissue, which is necessary for correcting severe myopia, can further reduce the thickness of the residual stromal bed (RST), thereby potentially increasing the risk of corneal ectasia. Corneal ectasia refers to the weakening and bulging of the cornea.


Beyond the Hype: Weighing the Options

While SMILE offers a promising future for correcting high myopia, it is important to approach it with realism and knowledge. Consider the following vital factors:

  • The Severity of Your Myopia:
    If your myopia exceeds -10 D, LASIK may be a more established and predictable option, especially if you have significant astigmatism or higher-order aberrations.
  • Individual Risk Factors:
    Factors such as overall eye health and corneal thickness play a role in determining the suitability of each procedure. To make the best decision, it is crucial to have a thorough consultation with a qualified ophthalmologist.
  • Long-Term Considerations:
    While SMILE is a relatively new procedure, long-term data on its efficacy and safety for correcting extremely high myopia is still being gathered. It is important to discuss the potential need for retreatment and associated costs with your doctor.


The Road Ahead: Refining and Researching SMILE

The future of SMILE for extremely high myopia holds immense potential. Ongoing research is currently dedicated to various critical areas of study:

  • Technological Advancements:
    Continuously refining lasers and treatment software to enhance accuracy and predictability for higher myopia corrections.
  • Personalized Approaches:
    Tailoring procedures and medications based on individual patient characteristics to optimize outcomes and ensure the best results.
  • Long-Term Studies:
    Gathering comprehensive data on the long-term safety and efficacy of SMILE for extremely high myopia, providing valuable insights to guide future clinical practice.


Making an Informed Choice

When deciding between SMILE and LASIK for treating extreme myopia, it’s crucial to consider individual factors. Collaborate with a knowledgeable ophthalmologist who can provide guidance on the merits and drawbacks of each option. This will ensure a safe and effective journey towards achieving a clearer vision. While SMILE shows promise, LASIK remains a reliable choice for complex cases. Stay engaged in ongoing research and maintain open communication with your doctor to make an informed decision for your eyes and future.

By understanding the current landscape and staying committed to research, SMILE has the potential to revolutionize high myopia correction. The path to clearer vision requires thoughtful consideration, informed choices, and a trusting partnership with your ophthalmologist.

By embracing both the present and the future, we can unlock the full potential of SMILE and empower individuals with high and extremely high myopia to experience a world without limitations—a world seen with unparalleled clarity.
