Introduction

Lens implant surgery has emerged as one of the most advanced and effective solutions for vision correction, especially for individuals who are not candidates for traditional LASIK or SMILE procedures. Over the years, this procedure has gained significant popularity due to its ability to address a wide range of vision issues, including nearsightedness, farsightedness, and astigmatism, in patients who may have thin corneas or high refractive errors.

At SNU Eye Clinic, located in the heart of Gangnam, Seoul, South Korea, we specialize in providing cutting-edge vision correction solutions, including lens implant surgery. Our expert team, led by Dr. Chung Eui Sang, has helped thousands of patients achieve clearer, sharper vision, utilizing the latest advancements in ophthalmic technology and personalized care.

In this guide, we will explore everything you need to know about lens implant surgery—what it is, who it’s for, how the procedure works, and why it might be the best option for you. By the end, you’ll have a clear understanding of how lens implants can improve your vision and quality of life.

What Is Lens Implant Surgery?

Lens implant surgery, also known as Implantable Collamer Lens (ICL) surgery, is a minimally invasive procedure designed to correct refractive errors by implanting a synthetic lens into the eye. The goal is to improve vision in individuals who have high levels of nearsightedness (myopia), farsightedness (hyperopia), or astigmatism, and for those who may not be suitable candidates for LASIK or other laser-based surgeries.

Unlike LASIK, which reshapes the cornea, lens implant surgery involves placing a small, biocompatible lens behind the iris, between the natural lens and the cornea. This lens works similarly to contact lenses but is permanent, offering a more stable solution for vision correction.

There are different types of lens implants available, including the standard ICL for general vision correction, as well as toric ICLs specifically designed for astigmatism, and multifocal lenses that can help with presbyopia (the age-related loss of near vision). At SNU Eye Clinic, we offer a variety of lens implant options to meet the unique needs of our patients, ensuring the best possible outcome for each individual.
