Professor Youngsub Eom's research lab specializes in anterior segment diseases and cataract surgery outcomes, with a strong focus on meibomian gland dysfunction (MGD), dry eye disease, and the impact of systemic and environmental factors on ocular surface health. The lab investigates biomechanical and biometric predictors for refractive error accuracy in cataract surgery, as well as the role of patient-specific factors—such as sleep patterns, hypertension, and medicinal plant use—in conditions like central serous chorioretinopathy (CSC). Additionally, the lab explores the ocular effects of environmental exposures, including airborne titanium dioxide (TiO2), and the immunological mechanisms underlying ocular surface inflammation. Their work integrates clinical trials, advanced biometry, and immunological analysis to improve postoperative outcomes and patient-centered care in ophthalmology.

In patients with obstructive MGD, MGL and meibum grade in the lower eyelids were significantly greater than those of the upper eyelids. Although MGL and meibum quality showed a positive correlation with each other, TBUT and corneal staining score were significantly correlated with only meibum grade, and not with MGL.
Hypertension, sleep disturbance, snoring, and medicinal plant use were identified as factors associated with CSC. Expanded history taking, including systemic factors and culture-specific behavior related to stress or fatigue such as use of medicinal plants, will be helpful in identifying Korean patients at an increased risk for CSC.
Hole ICL-evoked ring-shaped dysphotopsia was related to light refraction at the central hole structure. Surgeons are advised to explain to patients the possibility of ring-shaped dysphotopsia after hole ICL implantation.
The IOL power calculation formula selection method by biometry subgroup combined with biometric parameters K, ACD and AL may offer a more superior postoperative refractive error prediction in cataract surgery.
The purpose of this randomized clinical trial is to evaluate the effect of eyelid hygiene on subjective symptoms, anterior blepharitis, and meibomian gland dysfunction (MGD) after cataract surgery. Subjects with obstructive MGD who underwent cataract surgery were randomly divided into two groups. In the eyelid hygiene group, eyelid hygiene was performed twice a day for 10 days from 3 days before to 1 week after cataract surgery. The control group did not perform eyelid hygiene. A subjective symp
Exposure to airborne TiO2 induced ocular surface damage. The Type 2 helper T-cell pathway seems to play a dominant role in the ocular immune response following airborne TiO2 exposure.
IOL power calculation using adjusted corneal power according to the posterior/anterior corneal curvature radii ratio provided more accurate refractive outcomes than calculation using conventional K.
The majority of subjects were classified as having the obvious obstructive subtype of MGD, and 19.4% had upper and lower eyelids that were different subtypes. Eyelid hygiene was the most prescribed treatment for MGD patients, and treatment patterns were mostly determined based on the subtype of the upper eyelids.
