In this study, an in situ forming corneal stromal substitute based on collagen type I crosslinked by bio-orthogonal strain-promoted azide-alkyne cycloaddition (SPAAC) is presented. The gel has greater transparency compared to non-crosslinked gels. mechanical properties of the gels are controlled changing functional group ratios and conjugated concentrations. Higher concentrations yield enhances properties, where storage modulus increases from 42.39 ± 8.95 112.03 3.94 Pa after SPAAC...

Abstract Background This study aimed to determine the relationship between dyslipidemia and dry eye disease (DED) in a Korean population. Methods population-based enrolled 5,627 adults (aged >19 years) who were participating first year of fifth annual Korea National Health Nutrition Examination Survey from 2010 2011. Clinically diagnosed DED its symptoms surveyed, biochemical blood analysis data collected. Dyslipidemia was defined as any following: hypercholesterolemia (total cholesterol...

Purpose To elucidate the prevalence of cataract, glaucoma, pterygia, and diabetic retinopathy among Korean postmenopausal women with or without estrogen replacement therapy (ERT). Methods A cross-sectional, nationally representative sample from 4th Korea National Health Nutrition Examination Survey (KNHANES IV) (2007–2009) was used. Participants were interviewed for determination socioeconomic gynecologic factors. Each woman also underwent an ophthalmologic examination provided a blood risk...

To assess corneal inflammation from alkali chemical burns, we examined the therapeutic effects of in situ-forming hyaluronic acid (HA) hydrogels crosslinked via blue light-induced thiol-ene reaction on a rat burn model. Animals were divided into three groups (n = 7 rats per group): untreated, treated with 0.1% HA eye drops, and hydrogels. Crosslinking hydrogel followed by administration drops carried out once day days 0-4. Corneal re-epithelialization, opacity, neovascularization, thickness,...

The purpose of this study was to investigate the dysfunction autonomic control that may be a contributing factor in normal tension glaucoma (NTG) by showing short-term heart rate variability NTG patients.Newly diagnosed patients and an age-matched group were enrolled prospective study. Blood pressure obtained electrocardiogram monitored for 5 minutes after 30-minute rest supine position. Electrocardiographic signals transferred analyzer. time frequency domain parameters analyzed between two...

Dry eye disease (DED) is a common disorder characterized by unstable tear film homeostasis. Its symptoms range from foreign body sensations to pain and fluctuations in visual function. Current diagnostics include physical examination ocular surface imaging. Matrix metalloproteinase-9 (MMP-9) tears correlates with clinical signs of DED; however, because the limited sample volume, quantitative real-time detection MMP-9 significant need, complicated biochemical complexity tears. We developed an...

We compared the 3-year outcomes with regard to efficacy, stability, and safety of LASIK surface ablation performed at multiple centers in Korea.The charts 5109 eyes that underwent or ablation, including LASEK, epi-LASIK, photorefractive keratectomy (PRK), between 2002 2005 were reviewed. Of these, 577 LASIK-treated propensity score-matched surface-ablated included this cohort study. A standardized case report form (CRF) was completed based on a review follow-up chart. The CRF preoperative,...

Abstract The available treatment options include corneal transplantation for significant defects and opacity. However, shortage of donor corneas safety issues in performing are the main limitations. Accordingly, we adopted injectable situ-forming hydrogels collagen type I crosslinked via multifunctional polyethylene glycol (PEG)-N-hydroxysuccinimide (NHS) evaluated vivo biocompatibility. New Zealand White rabbits (N = 20) were randomly grouped into keratectomy-only keratectomy with...
