Patients with astigmatism trust SMILE LASIK surgery at SNU Eye Clinic for gentle procedures and long term vision clarity

Astigmatism has long been one of the most challenging refractive errors for patients seeking clear vision. Characterized by an irregular curvature of the cornea or lens, astigmatism often leads to blurred or distorted sight, making everyday tasks like reading, driving, or working on screens more difficult. Traditional LASIK surgery has provided relief for many, but patients with astigmatism frequently require a more precise and gentler approach. At SNU Eye Clinic in Seoul, SMILE LASIK has become the preferred option for correcting astigmatism, offering long-term stability, minimal invasiveness, and reliable clarity.

Understanding astigmatism and its challenges

Astigmatism is not a uniform condition; it can vary in degree and orientation, making correction more complex than standard myopia. Patients often complain of ghosting, halos around lights, or difficulty focusing on fine details. These challenges demand a treatment that is both accurate and gentle enough to preserve corneal stability. At SNU Eye Clinic, detailed diagnostic imaging is used to map each patient’s unique corneal shape. This ensures that surgery is designed specifically to address not just the degree of astigmatism but also the individual eye structure.

Why SMILE LASIK stands out for astigmatism patients

SMILE LASIK, short for Small Incision Lenticule Extraction, has revolutionized vision correction by using a femtosecond laser to create and remove a thin lenticule from within the cornea. For patients with astigmatism, this method provides several key advantages. Unlike traditional LASIK, SMILE or 렌즈삽입술  requires only a tiny incision—just 2 to 3 millimeters—rather than a full corneal flap. This smaller incision preserves more of the cornea’s biomechanical strength, which is crucial for astigmatism correction.

The precision of SMILE LASIK ensures that the correction is applied exactly where needed, aligning with the axis of astigmatism. This not only sharpens vision but also minimizes regression over time, allowing patients to enjoy long-lasting clarity. Many who previously feared traditional LASIK find SMILE to be far gentler, with quicker recovery and less risk of dry eye symptoms.

SMILE Pro and advanced alignment technology

SNU Eye Clinic has gone a step further with SMILE Pro, the next evolution of this technique. SMILE Pro incorporates faster laser platforms and robotic assistance, significantly reducing procedure time while enhancing precision. For astigmatism patients, accurate alignment is critical, and SMILE Pro’s centration technology ensures that the lenticule removal is perfectly centered according to each patient’s corneal axis.

This technological leap means that astigmatism correction is not only effective but also more comfortable for patients. With less time under the laser, fewer movements are required, and the procedure feels almost seamless. This innovation is one of the reasons patients with astigmatism across the world travel to Seoul to undergo treatment at SNU Eye Clinic.

The role of advanced imaging in precision

Astigmatism correction demands an exceptionally detailed pre-surgical analysis. At SNU Eye Clinic, OCT imaging, corneal wavefront analysis, and 3D topography provide a complete picture of the eye’s structure. These tools help identify corneal asymmetries and predict how the cornea will respond to lenticule removal. For patients with higher degrees of astigmatism, this ensures that the correction remains stable and effective for years to come.

Such detailed imaging also allows the surgical team to decide if SMILE LASIK is the best option or if lens implantation surgery, such as Zero Toric ICL, would provide better results. This flexibility ensures patients never undergo a procedure that might not provide optimal clarity.

Patient-centered expertise from pioneers in SMILE

Dr. Chung Eui-sang, CEO of SNU Eye Clinic, has been performing SMILE LASIK since 2011, making him one of the pioneers in this field. His expertise in adjusting surgical techniques for astigmatism, high myopia, and corneal irregularities ensures that each case receives individualized attention. Patients with astigmatism particularly benefit from this experience, as the surgical plan must be tailored to align perfectly with the irregular corneal curvature.

The result is not only sharp vision but also the reassurance that their correction is performed by a globally recognized expert in one of the most advanced ophthalmology facilities in Asia.

Gentle recovery and long-term clarity

One of the most significant benefits patients report after SMILE LASIK is the gentle recovery process. With such a small incision, the cornea heals quickly, and most patients experience minimal discomfort. For those with astigmatism, the long-term results are particularly rewarding. Studies have shown that SMILE LASIK provides excellent stability for astigmatism correction, with reduced risks of regression compared to older techniques.

The preservation of corneal integrity also means patients can return to normal activities faster, with fewer restrictions. Many are able to resume work, exercise, and daily routines within days, enjoying newfound clarity and freedom from glasses or contact lenses.

Alternatives for complex cases

While SMILE LASIK is highly effective, not all patients with astigmatism are ideal candidates. Those with extreme levels of refractive error or specific corneal conditions may benefit more from lens implantation options like Toric ICL. At SNU Eye Clinic, such procedures are performed using advanced 3D imaging systems to guarantee a safe and precise fit. Multifocal intraocular lenses are also recommended for patients with both astigmatism and presbyopia, offering comprehensive correction for distance and near vision.

The clinic’s commitment to offering multiple solutions ensures that no patient feels limited or excluded from achieving vision correction tailored to their unique needs.

A trusted destination for international patients

Astigmatism correction through SMILE LASIK has become one of the main reasons international patients travel to SNU Eye Clinic. Between 2022 and 2023, more than 1,200 patients from around the globe chose this clinic for its reputation in safety, precision, and successful outcomes. The combination of ZEISS certification, cutting-edge equipment, and experienced surgical expertise gives patients confidence that their treatment will meet the highest global standards.
