This article aims to offer a comprehensive comparison between Smile Pro Eye Surgery and ICL, assisting you in determining the best fit for your individual needs and making an informed decision. Whether you’re simply curious or about to make a big decision, keep reading to learn about the wonders behind these vision correction techniques.


What is Smile (Small Incision Lenticule Extraction) Pro Eye Surgery?

Introduced by ZEISS in 2023, this technique represents a relatively recent advancement in the field. Smile Pro eye surgery stands out as a cutting-edge laser refractive procedure utilizing the precise ZEISS VisuMax 800 Femtosecond laser to reshape the cornea and address refractive errors.


What is ICL (Implantable Collamer Lens)?

ICL, short for Implantable Collamer Lens, has been a reliable choice for vision correction since 1993, boasting a well-established track record. In contrast to Smile Pro eye surgery, ICL doesn’t require corneal reshaping through a laser. Instead, a special lens is inserted through a tiny incision in the sulcus that is behind the iris to address refractive errors.


Procedure Difference

Smile Pro is a corneal-based procedure that involves creating a micro incision to generate a small piece of corneal tissue known as a lenticule, which is then removed. This alteration of the cornea’s shape corrects the way light focuses on the retina. Additionally, Smile Pro eye surgery can be completed in as little as 7-9 seconds per eye.

In contrast, ICL is an intraocular refractive procedure where the lens is positioned in the sulcus—a space between the iris and the eye’s natural lens—through a small corneal incision without altering the natural corneal structure. This extra lens corrects vision by refocusing light onto the retina. Furthermore, ICL typically takes 15 to 20 minutes per eye.


Invasiveness and Structure

Smile Pro eye surgery is considered minimally invasive, involving only a small 2 mm incision without the need for any cuts. It directly reshapes the cornea and alters its natural structure, but the majority of the cornea remains untouched, thus preserving its strength and stability.

In contrast, ICL requires a small corneal incision to insert the collamer lens inside the eye, extending beyond the cornea and deep behind the pupil. This may be perceived as more invasive for some patients. However, it’s important to note that the lens insertion in ICL doesn’t reshape or alter the natural corneal structure’s shape or integrity.


Degree Correction Criteria

Smile Pro eye surgery is capable of correcting

  • Myopia (short-sightedness) up to -10 diopters and
  • Astigmatism up to -5 diopters.

In comparison, ICL can correct:

  • Myopia (short-sightedness): from -3.0 to -15.0 diopters,
  • Hyperopia (long-sightedness): from +1.00 to +12.00 diopters, and
  • Astigmatism: up to +4 diopters.


Ideal Candidates


Smile Pro Eye Surgery

  • Suitability:
    – Ideal for correcting nearsightedness, especially in mild to moderate cases.
    – Not suitable for hyperopia (farsightedness) and specific corneal conditions.
    – Not recommended for patients with thinner corneas or higher myopia.
  • Corneal Requirements:
    – Requires sufficient corneal thickness but often needs less depth compared to other laser surgeries.
  • Eye Health Considerations:
    – Suitable for those with dry eye symptoms, as it is less likely to exacerbate the condition.
  • Structural Changes:
    – Suitable for those individuals keen on maintaining the cornea’s natural structure as much as possible but does reshape the cornea.
  • Post-Surgery Lifestyle:
    – Flapless approach may be appealing to younger individuals.
    – Preferred for individuals with an active lifestyle due to fewer post-surgery restrictions.



  • Suitability:
    – Usually recommended for patients unsuitable for laser vision correction procedures.
    – Suitable for very thin corneas or high refractive errors with high myopia, hyperopia, or astigmatism.
    – Preferable for older adults with higher prescriptions.
    – Preferable for individuals with a less active lifestyle.
  • Corneal Requirements:
    – Maintains the cornea’s natural integrity, making it suitable for those who prioritize preservation.
  • Adaptability and Reversibility:
    – Offers adaptability with reversible options for potential changes in vision.
    – Does not change the cornea’s structure, allowing for future adjustments.
  • Long-Term Flexibility:
    – Lens can be replaced or adjusted for better solutions or significant vision changes.


Cost Comparison

The Smile Pro eye surgery is priced at around INR 125,000 to 150,000, encompassing the cost of the laser procedure, surgical expertise, as well as post-surgery care.

On the other hand, ICL carries a cost of around INR 80,000- 1,25,000, covering expenses for the specialized lens, surgical fees, and post-operative care, including follow-up visits.


Recovery Time

With Smile Pro, patients can typically expect a speedy recovery and full restoration of vision within a few weeks. Many experience improved vision on the same day, with minimal discomfort. They can resume work within 2 hours and engage in active sports like swimming, diving, bungee jumping, and football after two weeks.

In contrast, ICL may take up to one month for complete visual recovery, although improved vision is often restored by the next day with mild initial discomfort. Patients can resume work within 2-3 days and participate in active sports like swimming, diving, bungee jumping, and football after one month.


Side Effects

Smile Pro eye surgery greatly reduces the risk of dry eyes or halos around lights in low-light conditions.
In comparison, ICL has a higher risk of halos and dry eyes when compared to Smile Pro eye surgery.


Your Personalized Path to Clearer Vision

When it comes to vision correction surgeries, there are numerous options to consider, each with its own set of pros and cons.
Understanding the intricacies of Smile Pro and ICL empowers you to embark on a journey toward a clearer vision with confidence. The choice between these procedures is nuanced and personalized, taking into account your unique eye characteristics and preferences.

Engage in thorough consultations with your eye care professional, carefully considering your lifestyle and priorities. Make a decision that aligns with your vision goals and suitability criteria.

Both procedures boast impressive safety records, so whether you opt for the flapless wonder of Smile Pro or the lens addition advantage of the trusted ICL, the path to improved vision awaits.
