why ICL implantable collamer lens is better than laser refractive procedures like LASIK / SMILE IN INDIAN EYES WITH THIN CORNEAS AND ASTIGMATISM


In recent years, refractive surgeries like LASIK and SMILE have gained popularity for correcting vision problems, offering patients the promise of clear eyesight without glasses or contacts. However, for individuals in the Indian population with thin corneas and high astigmatism, these procedures may not always be the most suitable option. Implantable Collamer Lens (ICL) surgery emerges as a superior alternative, providing numerous advantages tailored to the specific needs of this demographic. Let’s delve into why ICL stands out as the optimal choice for achieving clear, stable vision in individuals with thin corneas and high astigmatism in India.

Preservation of Corneal Integrity:

In the Indian population, where thin corneas are more prevalent compared to other ethnic groups, preserving corneal integrity is paramount during vision correction surgeries. LASIK and SMILE involve reshaping the cornea by removing tissue, which can be risky for individuals with thin corneas, potentially leading to complications such as corneal ectasia. In contrast, ICL surgery bypasses this concern altogether by implanting a lens between the iris and natural lens, leaving the cornea untouched. This preservation of corneal integrity makes ICL a safer option for Indian individuals with thin corneas, minimizing the risk of long-term complications.

Effective Correction of High Astigmatism:

High astigmatism is a common refractive error among the Indian population, presenting a challenge for conventional laser surgeries like LASIK and SMILE. These procedures may have limitations in effectively correcting significant astigmatism, leading to suboptimal visual outcomes. ICL surgery, however, offers customizable correction for a wide range of refractive errors, including high degrees of astigmatism. The lens is tailored to the individual’s prescription, providing precise and effective correction even in cases of severe astigmatism commonly observed in the Indian population.

Stability and Predictability:

ICL surgery offers superior stability and predictability compared to LASIK and SMILE. Once implanted, the lens remains in a fixed position within the eye, ensuring consistent vision correction over time. This stability minimizes the risk of regression or fluctuations in vision, providing long-lasting results. Additionally, ICL surgery is associated with high predictability in terms of refractive outcomes, offering patients confidence in the reliability of their visual prognosis, a crucial factor for individuals in the Indian population seeking dependable vision correction.

Reversibility and Flexibility:

One notable advantage of ICL surgery is its reversibility and flexibility. Unlike LASIK and SMILE, which permanently alter the cornea, ICL surgery allows for the removal or exchange of the lens if the patient’s prescription changes significantly over time or if newer technologies emerge. This reversibility provides Indian patients with the assurance that their vision correction can be adapted as needed, offering long-term flexibility and peace of mind.

Cultural Considerations:

In addition to clinical factors, cultural considerations play a significant role in the preference for vision correction procedures in the Indian population. Many individuals prioritize long-term safety, stability, and reversibility of the chosen procedure, aligning with the inherent advantages of ICL surgery over LASIK and SMILE.


For individuals in the Indian population with thin corneas and high astigmatism, Implantable Collamer Lens (ICL) surgery emerges as the superior choice over LASIK and SMILE. With its ability to preserve corneal integrity, effectively correct high degrees of astigmatism, offer stability, predictability, reversibility, and flexibility, ICL provides a comprehensive solution tailored to the specific needs and cultural preferences of this demographic. Consultation with an experienced ophthalmologist is crucial to determine the most appropriate treatment option, but for many individuals in India, ICL stands out as the preferred choice for achieving clear, stable, and dependable vision correction
