Abstract Wearable contact lenses which can monitor physiological parameters have attracted substantial interests due to the capability of direct detection biomarkers contained in body fluids. However, previously reported lens sensors only a single analyte at time. Furthermore, such ocular generally obstruct field vision subject. Here, we developed multifunctional sensor that alleviates some these limitations since it was on an actual lens. It also designed glucose within tears, as well...
Abstract The microenvironments of tissues or organs are complex architectures comprised structural proteins including collagen. Particularly, the cornea is organized in a lattice pattern collagen fibrils which play significant role its transparency. This paper introduces transparent bioengineered corneal structure for transplantation. fabricated by inducing shear stress to stroma-derived decellularized extracellular matrix bioink based on 3D cell printing technique. printed recapitulates...
Significance Multimodal imaging based on optics and ultrasound can provide guide images complementary structural functional information, thus improving the accuracy of medical diagnosis treatment monitoring. However, because conventional transducers are opaque, in multimodal with optics, optical devices must be placed off-axis from transducer. This arrangement is prone to misalignment, adds complexity bulk system, result a low signal-to-noise-ratio. Here, we present transparent transducer at...
Integration of a smart contact lens and heat patch realizes personal management ocular surface diseases wirelessly.
Abstract Tears have emerged as a promising alternative to blood for diagnosing diabetes. Despite increasing attempts measure tear glucose using smart contact lenses, the controversy surrounding correlation between and still limits clinical usage of tears. Herein, we present an in-depth investigation wireless soft lens continuous monitoring glucose. This is capable quantitatively levels in basal tears excluding effect reflex which might weaken relationship with Furthermore, this can provide...
Corneal transplantation is a typical surgical procedure for severe corneal diseases. However, the waiting time donor cornea has gradually increased due to decrease in supply caused by an aging population and cases of laser-based surgeries. Artificial corneas were developed meet increase demand; however, these approaches have suffered from material deterioration resulted limited tissue integration. Here, we introduce cornea-derived decellularized extracellular matrix (Co-dECM) as bioink...
Abstract Herein, a wireless and soft smart contact lens that enables real‐time quantitative recording of cholesterol in tear fluids for the monitoring patients with hyperlipidemia using smartphone is reported. This incorporates an electrochemical biosensor continuous detection concentrations, stretchable antenna, integrated circuits communication, which makes only device required to operate this remotely without obstructing wearer's vision. The rabbit model utilized confirm correlation...
Glaucoma causes irreversible vision loss due to optic nerve damage and retinal cell degeneration. Since high intraocular pressure (IOP) is a major risk factor for glaucoma development, accurate IOP measurement crucial, especially intravitreal affecting the optical cells. However, conventional methods have limits in selectively directly detecting local retina pressure. Here, we present continuous measurements of values anterior chamber vitreous living animals using minimally invasive probes...
To study the incidence of and risk factors for postoperative capsular block syndrome (CBS) propose a new classification based on etiology.Department Ophthalmology, Kyungpook National University Hospital, Daegu, Republic Korea.Charts 1100 eyes 990 patients who had phacoemulsification posterior chamber intraocular lens (PC IOL) implantation between January 2003 June 2006 were retrospectively reviewed. Demographic data, axial length (AL), type PC IOL implanted, intraoperative ophthalmic...
Purpose:To evaluate the effect of platelet-rich plasma (PRP) eye drops in treatment recurrent corneal erosions (RCE).Methods: A total 47 eyes were included this retrospective study.Clinical records 20 consecutive patients with RCE who had been treated conventional lubricant (conventional group) from June 2006 to December 2008 and 27 autologous PRP addition (PRP January 2009 September 2014 reviewed.Major minor recurrences recorded compared between two groups.Results: This study 31 men 16...
Nanofiber (NF) membranes have demonstrated considerable potential in cellular transmigration studies due to their resemblance the biophysical properties of basement membranes, enabling behaviors that closely mimic those observed vivo. Despite advantages, conventional NF often encounter issues assays transparency, which leads overlapping fluorescent signals from transmigrated and nontransmigrated cells. This overlap complicates clear differentiation between these cell populations, making...
This study aimed to develop a novel multi-stage self-supervised learning model tailored for the accurate classification of optical coherence tomography (OCT) images in ophthalmology reducing reliance on costly labeled datasets while maintaining high diagnostic accuracy. A private dataset 2719 OCT from 493 patients was employed, along with 3 public comprising 84 484 4686 patients, 3231 45 and 572 images. Extensive internal, external, clinical validation were performed assess performance....
To evaluate and report the efficacy of fibrin glue (FG)-assisted augmented amniotic membrane transplantation (AMT) in patients with large corneal perforations.In a retrospective case series, 10 perforations more than 2 mm diameter were treated "FG-assisted AMT." A 5- or 7-ply "augmented membrane" (AM) was constructed by applying FG to each sheet AM repair perforation. The designed 0.5 larger transplanted onto perforation site 10-0 nylon suture. If needed, additional overlay sutured on...
Age-related macular degeneration (AMD) is the main cause of irreversible blindness among elderly and require early diagnosis to prevent vision loss, careful treatment essential. Optical coherence tomography (OCT), most commonly used imaging method in retinal area for AMD, usually interpreted by a clinician, OCT can help diagnose disease on basis relevant diagnostic criteria, but these judgments be somewhat subjective. We propose an algorithm detection AMD based weakly supervised...
<b><i>Purpose:</i></b> To compare surgical outcomes of sutureless flanged intraocular lens (IOL) fixation and conventional sutured scleral (SF) for secondary IOL implantation in patients with dislocation. <b><i>Methods:</i></b> This is a prospective, comparative cohort study on 103 consecutive (103 eyes) dislocation who underwent vitrectomy removal SF (53 or (50 eyes). Operating time, best-corrected visual acuity (BCVA), refractive difference,...
Purpose . To establish an optimized and standardized protocol for the development of optimal scaffold bioengineering corneal substitutes, we used femtosecond laser to process human tissue into stromal lenticules studied find most efficient decellularization method among various reagents with different tonicities. Methods The efficacy several agents (0.1%, 0.25%, 0.5% Triton X-100, SDS, trypsin-EDTA (TE), resp.) tonicities was evaluated. Of all protocols, methods, which efficiently removed...
To describe current cataract surgery practice patterns and changing trends among Korean ophthalmologists.A survey of members the Society Cataract Refractive Surgery was performed in July 2018. One hundred two (12.7%) 801 questionnaires were returned for analysis. The data analyzed using descriptive statistics compared with previous surveys.Most respondents (75%) had been 6 or more years an average 31 surgeries per month. preferred method phacoemulsification (95%); 5% used a femtosecond...
The aim of this article is to evaluate and classify pathogenetic origins based on morphologic reproliferative patterns in patients who underwent pterygium excision with a conjunctival autograft. In retrospective, observational case series, total 116 eyes autograft between February 2009 May 2011 were reviewed.
