FAQ
Yes. If tests show surgery isn’t appropriate, we say so. If dry eye or eye disease is the cause, we treat that first, and if vision is still changing, we advise waiting.
A dedicated ophthalmic technician performs detailed examinations, and Dr. Gye Hyeon Pung, Medical Director, personally reviews the results. If needed, we recalculate values with a second exam.
We reduce unnecessary tests, and repeat the decisive ones several times. Rather than increasing the number of items, we choose to narrow the error range of key values.
We check your progress at scheduled intervals, beginning either the evening of surgery or one week after surgery. We continue regular follow-up thereafter.
So we don’t decide based on a single measurement. We recalculate with a second exam to narrow the error range, then discuss the approach.
The medical team, including the dedicated doctor, reviews together and decides the method suited to that eye. It is not determined by one person’s judgment.
Because we have chosen to state only facts about our own clinic. We do not name or compare other clinics, and we do not publish anything unconfirmed by examinations or any figure without a source.
We look at the measurements with you and decide together what we can do and what is better left undone. The eye is optics and data, and we base what we tell you on that data.
Because outcomes vary from person to person, we do not promise specific numbers. On this website we state only what examinations confirm, and we publish no figures without a source.
We have chosen not to publish patient cases. Instead, we explain our decision criteria—which test results lead us to recommend which method.
Dr. Gye Hyeon Pung, Medical Director, reviews the results personally and then consults with you. We decide on the spot whether further tests are needed, and after recalculating values with a second exam, we discuss the method.
We consider your occupation, nighttime activities, how much you read, and even the time you spend on your phone. Just as we do not recommend multifocal lenses for those who drive a lot at night, we decide on an approach by considering test values together with your lifestyle.
Without testing, we cannot tell which approach is right. We recommend having an examination first; please call +82-2-555-1369 to find out which tests are needed.
Presbyopia and cataract revision surgery is part of the care we provide. Because a revision is more demanding than the first operation, we first confirm through examinations whether it is feasible before discussing it. Outcomes vary from person to person.
For presbyopia and cataract surgery, we use a machine-learning–based prognosis support program (June 2023) alongside the examination results. Surgical planning is based on each patient’s examination data.
