Corneal Endothelial Cell Changes After Femtosecond Laser-Assisted Cataract Surgery in Diabetic and Nondiabetic Patients.

Objective: To compare corneal endothelial cell changes after femtosecond laser-assisted cataract surgery (FLACS) in diabetic and nondiabetic patients.

Methods: This retrospective study included patients with cataract who underwent FLACS performed by a single surgeon between August 2018 and November 2020. Changes in corneal endothelial cell density (ECD), hexagonality, coefficient of variation in cell size (CV), and central corneal thickness (CCT) at baseline and at the 1-month and 3-month postoperative follow-ups were investigated by dividing the patients into diabetic and nondiabetic groups.

Visual Performance and Optical Quality after Implantation of a New Generation Monofocal Intraocular Lens.

Purpose: To evaluate the performance of two intraocular lenses (IOLs). The new monofocal IOL using a higher-order aspheric optic (Tecnis Eyhance ICB00) was compared to a standard monofocal IOL (Tecnis monofocal ZCB00) of the identical platform and material.

Methods: The medical records of the patients who had undergone cataract surgery with implantation of either the ZCB00 or the ICB00 in the dominant eye from March 2020 to August 2020 and with available data from the 3-month visit were reviewed.

Relationship between the partial blink rate and ocular surface parameters.

Purpose: To elucidate the relationship between partial blink rate (PBR) and ocular surface parameters.

Methods: We conducted a retrospective cross-sectional study of the patients who visited the Kim's Eye Hospital between March 2020 and July 2020. Blinking dynamics, tear film lipid layer thickness (LLT), non-invasive tear film break- up time (NITBUT), tear meniscus height (TMH), and meibomian gland (MG) dropout rate were assessed using the IDRA Ocular surface analyzer (SBM SISTEMI, Inc.

Ocular surface analysis: A comparison between the LipiView II and IDRA.

Purpose: To compare the lipid layer thickness (LLT), meibomian gland (MG) dropouts, and blinking pattern determined by the analysis of images acquired from the LipiView II (LVII) and the IDRA Ocular surface analyzer.

Methods: A cross-sectional single-visit observational study was conducted. The LLT (minimum, maximum, and average), percentages of MG dropouts, and partial blink rates (PBR) were taken from both eyes of 47 participants using LVII and IDRA.

Combined Phototherapeutic Keratectomy and Peripheral Anterior Stromal Puncture for the Treatment of Recurrent Corneal Erosion Syndrome.

Purpose: To investigate the efficacy of the combined phototherapeutic keratectomy (PTK) and peripheral anterior stromal puncture (ASP) compared with that of PTK alone in patients with recurrent corneal erosion syndrome (RCES).

Methods: The medical records of 25 patients (25 eyes) who underwent combined treatment of PTK and peripheral ASP for RCES from March 2016 to May 2017 were retrospectively reviewed. Twenty-three patients (23 eyes) treated with PTK alone from March 2015 to February 2016 served as a control group.

Background: To report a case of enucleation caused by Streptococcus dysgalactiae endophthalmitis after traumatic corneal laceration.

Case Presentation: A 69-year-old man with history of retinal detachment treated with vitrectomy and subsequent cataract surgery presented with traumatic corneal laceration while cutting grass. Appropriate repair of corneal laceration and intravitreal antibiotics (vancomycin, ceftazidime) injection was performed.

Lenticular fungal infection caused by Aspergillus in a patient with traumatic corneal laceration: a case report.

Background: To report a case of lenticular infection caused by Aspergillus, which was diagnosed 13 weeks after traumatic corneal laceration.

Case Presentation: A 60-year-old woman presented with traumatic corneal laceration including anterior lens capsule rupture and traumatic cataract after being hit with a chestnut in the right eye. There were multiple injuries due to tiny thorns of the chestnut, including the conjunctiva, sclera, cornea, and anterior lens capsule.

Changes of tear film lipid layer thickness by 3% diquafosol ophthalmic solutions in patients with dry eye syndrome.

Aim: To evaluate the quantitatively changes in lipid layer thickness (LLT) when 3% diquafosol eye drop is used for dry eye patients using the tear film interferometer.

Methods: A total 124 participants (32 males, 92 females; mean age, 28.9y) diagnosed with dry eye disease (DED) received topical instillation of 4 ophthalmic solutions in one eye: diquafosol, normal saline, 0.

Changes in Tear Volume after 3% Diquafosol Treatment in Patients with Dry Eye Syndrome: An Anterior Segment Spectral-domain Optical Coherence Tomography Study.

Purpose: To evaluate changes in the tear meniscus area and tear meniscus height over time in patients with dry eye syndrome, using anterior segment spectral-domain optical coherence tomography after the instillation of 3% diquafosol ophthalmic solution.

Methods: Sixty eyes from 30 patients with mild to moderate dry eye syndrome were included. Tear meniscus images acquired by anterior segment spectral-domain optical coherence tomography were analyzed using National Institutes of Health's image-analysis software (ImageJ 1.

Adding enzymes to improve the properties of the Korean barley Gwangmaek wort during mashing.

This study investigated the properties of the Korean barley Gwangmaek wort and compared them to those of the imported Pilsner. The reducing sugar content of Gwangmaek (52.13 mg/mL) was 13% lower than that of Pilsner.

Expression of microRNAs in fibroblast of pterygium.

Aim: To screen microRNAs (miRNAs) and set up target miRNAs in pterygium.

Methods: Primary fibroblasts were isolated from pterygium and Tenon's capsule and cultured. Immunocytochemical analysis and Western blotting were performed to confirm the culture of fibroblasts.

Development of EKC after eximer laser photorefractive surgery and subsequent recurrence of EKC-like keratitis.

This research focuses on four cases of patients having undergone eximer laser photorefractive surgery who were diagnosed with adenoviral keratoconjunctivitis during the postoperative period and who later developed epidemic keratoconjunctivitis (EKC)-like keratitis. Two of the patients had undergone laser-assisted subepithelial keratectomy (LASEK), one had undergone laser in situ keratomileusis and one had photorefractive keratectomy. After the surgery adenoviral keratoconjunctivitis and recurrent late-developing EKC-like keratitis were observed in the patients.

Epidermophyton fungal keratitis following laser-assisted subepithelial keratectomy.

A 40-year-old man developed pain, decreased vision, and a corneal infiltrate 10 days after laser-assisted subepithelial keratectomy. Treatment with conventional topical and systemic antibiotic agents did not improve the symptoms. Approximately 2 weeks after surgery, the patient was referred to Kim's Eye Hospital, presenting with counting fingers visual acuity, moderate anterior chamber reaction, and multifocal stromal infiltrates in the left eye.

No association of prion protein gene polymorphisms with Alzheimer's disease in Korean population.

The polymorphism at codon 129 (M129V) of the human prion protein gene (PRNP) is a known risk factor for Creutzfeldt-Jakob disease (CJD) in Caucasians. There are few reports of this polymorphism's effect on memory and on the risk of Alzheimer's disease (AD). The M129V genotype distributions among Asians are very different from Caucasians.
