SNU Eye Clinic outlines when cataract surgery makes sense for patients over 50

SNU Eye Clinic in Seoul says patients over 50 should base cataract surgery timing on symptoms, cataract progression and daily life impact — not age alone. The clinic also says intraocular lens choice and communication support matter for overseas patients traveling to Korea for treatment.

Why it matters: - Cataracts and presbyopia often appear together after age 50, which can make symptoms harder to sort out and delay the right treatment decision. - The timing of surgery can affect both difficulty of the procedure and the risk of complications if a cataract becomes advanced. - Lens choice can shape visual quality, convenience and satisfaction after surgery. - Overseas patients traveling to Korea also need clear communication to understand exam results, surgical options and aftercare.

What happened: - SNU Eye Clinic in Gangnam, Seoul, explained when patients over 50 should consider cataract surgery and what factors should guide intraocular lens selection. - Dr. Chung Eui Sang, chief director of SNU Eye Clinic, said cataracts do not always require immediate surgery and that regular eye exams help determine the right timing. - Dr. Chung also said lens selection should reflect the patient’s eye condition, lifestyle and visual needs.

The details: - Cataracts occur when the eye’s natural lens becomes cloudy, causing blurred or hazy vision. - Common symptoms include reduced visual acuity, glare, halos around lights and double vision. - Presbyopia can develop at the same time, making the conditions hard to distinguish from symptoms alone. - Some patients may think near vision has improved without reading glasses, but that can be “index myopia” tied to cataract-related lens changes. - Regular eye exams are especially important for people with high myopia, diabetes, uveitis, previous eye trauma, excessive ultraviolet exposure or long-term steroid use. - Cataract diagnosis does not automatically mean surgery is needed right away. - In early stages, doctors can monitor cataract progression through regular examinations and use medication when appropriate. - Medication cannot restore transparency to a lens that has already become cloudy. - Surgery should be considered when vision loss interferes with driving, reading or work. - Surgery may also be needed when lens displacement, inflammation or increased intraocular pressure is present. - Delaying surgery too long can make the natural lens harder and the operation more technically difficult. - A swollen lens can block aqueous humor flow, raise intraocular pressure and increase complication risk. - Intraocular lenses used for cataract and presbyopia surgery include monofocal and multifocal options with different optical characteristics. - Lens choice should take into account high myopia, astigmatism, retinal health, dry eye, occupation, lifestyle, viewing distances and night driving frequency. - SNU Eye Clinic says interpretation support is available during examinations, consultations and medical appointments for overseas patients. - The clinic says that support helps patients understand their eye condition, treatment options, lens selection criteria and postoperative care. - SNU Eye Clinic provides ophthalmic care for domestic and overseas patients, including vision correction procedures and treatments for presbyopia and cataracts.

Between the lines: - The clinic is positioning cataract care as a decision that depends on function, not just diagnosis or age. - The message also reflects a broader medical tourism pitch: patients are expected to compare not only surgical expertise but also communication support and care coordination. - The focus on lens choice suggests that cataract surgery is being presented as both a medical treatment and a lifestyle decision. - Dr. Chung’s background at Seoul National University College of Medicine, Samsung Medical Center and Harvard Medical School’s Schepens Eye Research Institute adds institutional credibility to the clinic’s message. - Dr. Chung was named to The Ophthalmologist’s 2026 Power List Top 50, which the clinic cites as evidence of his international academic profile.

What's next: - Patients over 50 considering cataract surgery are being advised to continue regular eye exams and discuss timing with an ophthalmologist. - Overseas patients planning treatment in Korea are expected to review lens options, surgical precautions and follow-up care before making a decision. - SNU Eye Clinic says its interpretation support system is in place to guide overseas patients from examination through surgery and recovery.

The bottom line: - Cataract surgery should be timed to the patient’s symptoms and lifestyle, not just the calendar age or the moment of diagnosis.
