Why have your retina treated at GS?
Three reasons patients choose GS for retinal care: a dedicated retina clinic led by university hospital-trained retina doctors; a nine-device diagnostic and surgical lineup that finds disease early; and sutureless 25-gauge vitrectomy, which means admission, surgery and discharge on the same day. Here is what stands behind each claim.
What makes retinal care at GS different?
A dedicated retina clinic
Retinal care at GS runs as its own clinic, in the hands of Dr. Park Sungwook and Dr. Lee Jiyoung - both trained in retina at university hospitals - with its own floor, inpatient room and equipment lineup.
A full diagnostic lineup
Six diagnostic systems - angiography, wide-field imaging without dilation, ultrasound, dual OCT platforms and visual field analysis - catch disease that is still silent.
See the equipmentSame-day surgery, no sutures
Vitrectomy through 25-gauge (0.5 mm) incisions needs no stitches, so admission, surgery and discharge happen on the same day - no overnight stay.
How treatment worksEvery treatment path in-house
Injections, laser and micro-incision surgery on the Alcon Constellation platform under the ZEISS Lumera 700 microscope - the answer to your diagnosis does not require a referral elsewhere.
Who will be looking after your retina?
Retina care at GS is in the hands of Dr. Park Sungwook and Dr. Lee Jiyoung, both trained in retina at university hospitals before joining GS.


Two surgeons on the vision correction team, Dr. Lim Sunghyup and Dr. Lee Sungwoo, also hold retina fellowship training from university hospitals. All seven doctors, including the wider vision correction and cataract team, are on the doctors page.

Questions about the retina clinic
The retina clinic is in the hands of Dr. Park Sungwook and Dr. Lee Jiyoung, both trained in retina at university hospitals. Injections, laser and vitrectomy are all carried out in-house rather than referred elsewhere.
No. Vitrectomy at GS is sutureless, through 25-gauge (0.5 mm) incisions, so admission, surgery and discharge happen on the same day. Gas-fill cases (macular hole, retinal detachment) have positioning instructions and about 2-3 weeks of reduced vision afterward, which your surgeon explains in advance.
Because the retina is the film every other procedure depends on. If the retina is not healthy, no surgery can deliver clear vision - so GS screens for and treats retinal disease with the same team and equipment lineup that supports its vision correction and cataract practice.
Nine conditions, including macular degeneration, diabetic retinopathy, retinal vein occlusion, epiretinal membrane, macular hole, retinal detachment, dislocated intraocular lens, myopic choroidal neovascularization and central serous chorioretinopathy. Each is described on the conditions page.
