Understanding the Difference Between Laser Eye Surgery and ICL Surgery

Advancements in vision correction have provided more people with the opportunity to reduce or eliminate their dependence on glasses and contact lenses. With so many options available, it can be overwhelming to determine which procedure is best suited to your vision needs. This article explores laser vision correction procedures—including LASIK, PRK, and LALEX/SMILE—alongside Implantable Collamer Lens (ICL) surgery, helping you make an informed choice.

What is Laser Eye Surgery?

Laser eye surgery is a popular and effective method for reshaping the cornea to correct refractive errors, including short-sightedness (myopia), long-sightedness (hyperopia), and astigmatism. The three primary forms of laser vision correction are:

• LASIK (Laser-Assisted In Situ Keratomileusis): A two-step laser procedure that creates a thin flap in the cornea before reshaping the tissue underneath to correct vision.
• PRK (Photorefractive Keratectomy): A flap-free procedure where the surface layer of the cornea is gently removed before laser reshaping, making it suitable for patients with thinner corneas.
• LALEX/SMILE (Lenticule Extraction Procedures): A minimally invasive technique that removes a small piece of corneal tissue through a keyhole incision, preserving more corneal strength.

What to Expect from Laser Vision Correction

• Fast and effective procedures, typically taking less than 20 minutes.
• Minimally invasive techniques that promote quick recovery.
• Personalised treatments designed for your specific vision needs.
• Long-term vision improvement, reducing the need for glasses or contact lenses.

While laser eye surgery is an excellent option for many, some individuals with high prescriptions or corneal conditions may not be suitable candidates. In such cases, ICL surgery provides an alternative solution.

What is ICL Surgery?

Implantable Collamer Lens (ICL) surgery is a non-laser alternative for vision correction, ideal for those who may not be suitable for LASIK, PRK, or LALEX/SMILE due to higher prescriptions or thin corneas.

During ICL surgery, a small, biocompatible lens is placed inside the eye, behind the iris to provide clear vision without altering the cornea’s natural shape. This lens works like a permanent contact lens, offering sharp, high-definition vision.

Why Consider ICL Surgery?

• Ideal for high prescriptions beyond the limits of laser surgery.
• Reversible procedure, as the lens can be removed or replaced.
• Preserves the natural corneal structure, unlike laser reshaping.
• Suitable for patients under 40 who don’t have cataracts.

ICL surgery is particularly beneficial for those who want a reversible vision correction solution while maintaining the natural shape and thickness of the cornea.
