      I would like to express my heartfelt thanks to the entire team at ISEC, especially my cornea specialist, Dr. Then KY. Although he may seem quiet and serious at first, he is actually a very kind, compassionate, and dedicated doctor. Due to my own negligence, I suffered repeated eye infections that almost caused me to lose my vision. Thanks to his expertise, surgical skills, and never giving up on me, I was able to get through a complex surgery and return to my normal life. Without his long-term care and dedication, I truly believe I would have lost my eyesight completely. I can never thank him enough. I would also like to thank my glaucoma specialist, Dr. Fang SK, who performed my glaucoma implant surgery years ago. His experience, skill, and dedication helped preserve my vision, and I will always be grateful for everything he has done. I also want to thank every member of the ISEC team. From the registration counter to the nurses, cashiers, and support staff, everyone has always been friendly, professional, patient, and helpful. They made every visit feel comfortable and reassuring. ISEC is an excellent eye care centre that provides high-quality treatment at reasonable prices. I highly recommend ISEC to anyone looking for the best eye care. Thank you to everyone at ISEC for giving me the priceless gift of sight.

      Today, I had a very reassuring experience with Dr. Then Kong Yong at ISEC. This was my second visit after being referred to him by my marriage mentor Bro David Wong, and I’m truly grateful for the recommendation. Knowing that Dr. Then received extensive training in the UK, including at St. George’s Hospital and King’s College, University of London, as well as his Fellowship from the Royal College of Surgeons of Edinburgh, gave me great confidence in his expertise. But what impressed me even more was his patience and compassion. I went into today’s appointment feeling very anxious about my eye condition. I had even experienced sleepless nights worrying about it, and many family members, friends and church brothers and sisters had been praying for me. After checking my eyes, Dr. Then reassured me that my eye pressure is currently under control. I will need to continue my eye drops consistently for the long term and return in three months for further assessment. When I shared with him how worried I had been and that many people were praying for me, he gently smiled and said, “God must have answered their prayers.” That simple sentence really touched and comforted me. Dr. Then may appear quite serious at first 😊, but behind that is a very patient, compassionate and reassuring doctor. He listened to my concerns, explained things clearly, and reminded me firmly about the importance of being disciplined with my daily eye drops. I walked out of his consultation room feeling relieved, encouraged and very grateful. Thank you, Dr. Then, for combining your medical expertise with genuine care and compassion. And thank you to the ISEC team for your professionalism and care. Malaysia is truly fortunate to have doctors of this calibre. 🙏

      I had a corneal transplant and cateract surgery done by Dr Then Kong Yong recently. Dr Then KY is an experienced corneal specialist, he explained my eye conditions and politely answered all my questions about the treatment. Overall I felt Dr Then KY was professional, kind and approachable, and I appreciate the clarity I did get. The downside is the consultations felt rushed because of the queue. Maybe offering slightly longer appointments or a nurse for basic questions would help. Thank you to the team for managing so many patients.

      I took my parents to consult Dr Then on their eyes. They were very happy with his meticulous explanation and assurance on their eyes condition and how the treatment plan was being suggested to my dad. Dr Then was awesome. Front desk was welcoming and the payment counter was absolutely helpful. Well done and keep it up Isec!
