Beyond the surface: LASIK vs ICL for long-term vision correction

When it comes to vision correction, LASIK (Laser-Assisted In Situ Keratomileusis) is one of the most well-known and popular procedures. However, not everyone is a suitable candidate for LASIK, and that’s where ICL (Implantable Contact Lens) comes in as an alternative option. Both procedures offer long-term vision correction, but they differ in how they work, their suitability for patients, and their long-term effects.

In this post, we'll dive into the differences between LASIK and ICL, exploring which might be the best option for you and what each procedure involves. Understanding these options will help you make an informed decision for your eye health.

What is LASIK?

LASIK is a type of laser eye surgery that reshapes the cornea to correct common refractive errors such as myopia (short-sightedness), hyperopia (long-sightedness), and astigmatism. During the procedure, a small flap is created on the surface of the cornea, and the underlying tissue is reshaped with a laser to improve how light focuses on the retina. The flap is then repositioned, and the eye heals naturally over time.

LASIK has been used for over two decades and is known for its fast recovery time, with many patients noticing an improvement in their vision within 24 hours. However, it’s not suitable for everyone, particularly for those with thin corneas or severe refractive errors.

What is ICL?

ICL, or Implantable Contact Lens, is an alternative to LASIK for people who may not be suitable candidates for laser eye surgery. Instead of reshaping the cornea, an ICL procedure involves implanting a small, flexible lens in front of the eye's natural lens, between the iris and the cornea. The implanted lens helps correct vision by focusing light more accurately onto the retina.

ICL is reversible and does not involve the removal of any corneal tissue, making it an attractive option for patients with thin corneas or extreme refractive errors. The procedure can correct myopia, hyperopia, and astigmatism and is considered a long-term solution for vision correction.

Key Differences Between LASIK and ICL

1. How They Work
LASIK reshapes the cornea using a laser to improve the eye's focus. It permanently changes the cornea’s shape to correct refractive errors.
ICL, on the other hand, does not alter the shape of the cornea. Instead, a lens is implanted inside the eye to correct vision. This lens remains in place permanently but can be removed or replaced if necessary.

2. Suitability for Patients
LASIK is best suited for individuals with mild to moderate vision problems and corneas thick enough to handle the reshaping process. People with thin corneas, severe refractive errors, or certain eye conditions may not be ideal candidates for LASIK.

ICL is often recommended for people who are not suitable for LASIK, particularly those with thin corneas or higher levels of refractive error. It’s also a good option for those with dry eyes, as LASIK can sometimes exacerbate dry eye symptoms.

3. Reversibility
LASIK is permanent. Once the cornea has been reshaped, it cannot be reversed. While the procedure is safe and effective for most people, it’s important to remember that LASIK is a one-time, irreversible procedure.

ICL is reversible. The implanted lens can be removed or replaced if necessary, making it a flexible option for patients who may want to explore other vision correction options in the future.

4. Recovery Time
LASIK has a quicker recovery period compared to ICL. Most patients experience noticeable improvements in their vision within a day or two and can resume normal activities within a week.

ICL recovery can take a little longer, with full visual clarity taking a few days to a week to stabilise. However, patients can usually return to work and daily activities within a few days.

5. Long-Term Results
LASIK offers long-lasting vision correction, but vision changes can occur as you age, especially if you develop presbyopia (age-related near vision problems) or other conditions. Some people may require enhancement procedures later in life.

ICL provides long-term correction and, because the lens can be replaced, offers more flexibility in the future. If your prescription changes significantly, the lens can be updated without needing a major surgical intervention.

6. Cost
The cost of LASIK in South Africa generally ranges between R20,000 and R40,000/ eye, depending on the clinic, the surgeon, and the type of technology used. ICL tends to be more expensive than LASIK, with prices typically starting at around R30,000 to R50,000 per eye. However, for some patients, the additional cost of ICL is justified by the procedure’s suitability and flexibility.

Risks and Side Effects

Both LASIK and ICL are safe, effective procedures with high success rates, but like any surgery, they come with potential risks.

• LASIK risks include dry eyes, glare, halos around lights, and under-correction or over-correction, which may require a follow-up procedure.
• ICL risks are minimal, but they can include infection, increased eye pressure (which could lead to glaucoma), or cataract formation in rare cases. Your surgeon will assess your individual risks and discuss them with you before the procedure.

Which Procedure is Right for You?

Choosing between LASIK and ICL depends on several factors, including your vision needs, the health of your corneas, and your long-term goals for vision correction.

If you have mild to moderate vision issues, and your corneas are thick enough, LASIK may be the better choice due to its quick recovery and high success rate.

If you have thin corneas, severe refractive errors, or want a reversible option, ICL might be more suitable.

It’s important to have a comprehensive consultation with an eye specialist to determine which procedure is right for you. Your surgeon will assess your eye health, vision requirements, and personal preferences to help you make an informed decision.

Conclusion

Both LASIK and ICL offer effective, long-term solutions for vision correction, but they serve different needs. LASIK provides a permanent fix for those with mild to moderate refractive errors, while ICL is ideal for individuals with more complex vision issues or thin corneas. Whichever procedure you choose, the results can be life-changing, offering you clear, sharp vision without the need for glasses or contact lenses.
