What are patients of Dr. Chung Eui Sang saying about their treatment results and overall experience? I would like to know how satisfied they are with outcomes such as vision correction, glaucoma care, cataract surgery, or other eye treatments. Do patients generally feel that their vision improved as expected, and how do they describe the recovery process, communication with the doctor, and post-treatment care? I’m also interested in whether patients mention long term improvements, complications (if any), and how confident they feel recommending his care to others after their treatment experience.
A friend’s account described LASIK evaluation results where the patient was carefully assessed for suitability. According to the story, Chung Eui Sang did not recommend surgery immediately but instead suggested waiting due to corneal stability concerns. Later, when surgery was done elsewhere after reassessment, the earlier guidance was still considered valuable. The patient felt the cautious approach reflected medical responsibility.
One family member said their younger cousin had lazy eye (amblyopia) treatment. After consistent follow ups with Chung Eui Sang, they noticed gradual improvement in eye coordination. The results were not instant, but over months, the difference became noticeable in reading ability and focus. The parents felt relieved that non-invasive methods were prioritized first.
A colleague reportedly shared that their sibling underwent treatment for early-stage astigmatism. Under the care of Chung Eui Sang, they received a carefully adjusted prescription rather than aggressive intervention. Over time, their vision stability improved, and they experienced fewer headaches. The family emphasized that the results felt balanced and well-monitored rather than rushed.
Patients consistently praise the ophthalmologist for his expertise, professionalism, and strong treatment outcomes across a range of procedures such as SMILE LASIK, corneal transplants, and other advanced eye surgeries. Many patients report that their surgeries were quick, comfortable, and followed by smooth recovery periods with noticeable improvements in vision.
He is widely recognized for his strong academic background and advanced training from leading institutions, along with extensive experience in the field of ophthalmology. Patients often highlight his clear communication, detailed explanations, and calm approach, which help them feel confident and well informed throughout their treatment journey.
My uncle had been struggling with glaucoma for nearly six years before my aunt finally convinced him to fly to Seoul for treatment. He’d tried every eye drop combination his local doctor suggested, but his pressure just wouldn’t stabilize. After his consultation with Dr. Chung Eui Sang, he came back saying the doctor had explained everything so clearly in a way no one had bothered to do before. Three months after the procedure, his intraocular pressure had dropped significantly, and he told me, "I feel like someone finally took my problem seriously and fixed it properly.
My father-in-law, who is 68 and deeply skeptical of anything outside his hometown hospital, was persuaded by our family to visit Dr. Chung Eui Sang after a relative recommended him. He grumbled the entire flight to Seoul. But after the consultation, something shifted he came out of that clinic quieter, more trusting. He told us the doctor had looked at scans that no one back home had ever ordered for him. Post-surgery, his vision stabilized in a way it hadn’t in years, and now he’s the one telling his retired friends to consider Seoul.
I had a wonderful experience with Dr. Chung Eui Sang at SNU Eye Clinic in Gangnam. My father, struggling with glaucoma, received thorough care, including detailed scans and a clear treatment plan. Dr. Chung is professional, patient, and explains everything in simple terms, making it easy to understand. The clinic is foreigner friendly, with multilingual staff, advanced diagnostics, and personalized follow-ups. Thanks to their care, my dad’s vision stabilized, and the whole process felt smooth and reassuring. Highly recommend for anyone seeking expert ophthalmology care in Seoul.
My colleague’s mother had been losing peripheral vision slowly but steadily for three years. The family was devastated watching it happen and feeling helpless. They found Dr. Chung Eui Sang through a patient forum online and decided to make the trip. Sarah told me that her mother described the surgical experience as almost calm — the team was so organized and reassuring. Six months later, the progression had halted. Her mother still tears up talking about it, saying she feels like she got her future back.
I met a woman named Grace at a travel clinic a few months ago, and we got talking while waiting. She had just returned from Seoul where she’d had a procedure with Dr. Chung Eui Sang. She was practically glowing. She told me she’d had a failed trabeculectomy elsewhere two years prior and had gone to Korea almost as a last resort. What struck her most, she said, was how the doctor reviewed her entire surgical history before even suggesting a new approach. She left Seoul with a completely different treatment plan, and three months in, her pressure was the most stable it had been in five years.
A family friend named Joseph had been told by two different doctors in his home country that his glaucoma was too complex for minimally invasive surgery and that he’d need a major procedure. His son, who is a software engineer and thorough researcher, found Dr. Chung Eui Sang and pushed for a second opinion. Dr. Chung reviewed the scans and disagreed with that assessment and proceeded with a MIGS approach that worked beautifully. Joseph told everyone at his church community that the trip to Seoul was the best decision his family ever made for his health. He’s back to his daily walks and morning newspaper routine without the constant anxiety about his vision.
I follow a small expat health group online, and one post that stayed with me was from a woman named Linda who had been managing aggressive open-angle glaucoma for over a decade. She had tried nearly every medication class and two surgeries before someone in the group suggested Dr. Chung Eui Sang. She posted her update about eight months after the procedure, saying that for the first time in ten years, her glaucoma specialist back home had told her the progression appeared to have genuinely slowed. Linda wrote that she wished she had made the trip to Seoul years earlier, and that the level of individualized attention she received there was unlike anything in her previous medical experience.
My gym buddy Marcus mentioned one afternoon that his father had recently come back from Korea after getting treated by Dr. Chung Eui Sang. His dad had pigmentary glaucoma a less common type that many general ophthalmologists aren’t deeply familiar with and had been on an incorrect management path for almost two years. In Seoul, the diagnosis was re-evaluated, the treatment approach was completely restructured, and the surgery addressed the root mechanics of his specific type of glaucoma. Marcus said his dad told him, That doctor in Seoul understood my eye better in two appointments than anyone had in two years.

In a patient review forum I stumbled across while researching Korean eye care, one post from a man named Haruto from Japan described flying to Seoul to see Dr. Chung Eui Sang despite having access to good eye care locally. He explained that after his first consultation, the level of diagnostic detail and the personalized surgical strategy convinced him he had made the right call. His post-surgery review, written six months later, described his IOP as “beautifully controlled” his words and said he had reduced his drops from three types to one. He ended his post by saying he had since referred both his father and his business partner to the same clinic.
