Abstract:

Decorin (DCN) is involved in a variety of physiological and pathological processes. Epithelial-mesenchymal transition (EMT) of lens epithelial cells (LECs) has been proposed as a major cause for the development of posterior capsule opacification (PCO) after cataract surgery. We investigated the plausible target gene(s) that suppress PCO. The expression of Dcn was significantly upregulated in rat PCO tissues compared to that observed in the control using a microarray-based approach. LECs treated with fibroblast growth factor (FGF) 2 displayed an enhanced level of DCN expression, while LECs trea

MONITORING OF EYE LENS DOSE HP(3) CATHLAB STAFF USING SOCA DOSIMETER. The International Commission on Radiological Protection (ICRP) reduced the cataract threshold dose from 2‒5 Gy to 0.5 Gy, followed by a decrease in the dose limit value (NBD) of the radiation worker's eye lens to 20 mSv/year. Cathlab staff is one of the workers vulnerable to receiving high doses of eye lenses because they work near radiation sources, so staff's eye lens doses need to be monitored. Monitoring is carried out to analyze the dose of eye lenses received by workers and ensure workers are well protected. Eye lens m

Abstract:

Abstract The International Commission on Radiological Protection recommended a significant reduction of the equivalent dose limit for the eye lens. Reportedly, medical staff in charge of diagnostic imaging procedures may exceed the new dose limits for the eye lens. The use of dosimeters dedicated to the eye lens remains low, and dosimeters for the neck region were often used to assess eye lens doses. However, measurements by neck badges may overestimate or underestimate the recommended eye lens doses because the height of the neck differs from that of the eye. This study aimed to evaluate the

Bending, membrane and transverse shear loads within the lens are also computed. Commercial soft contact lenses and a representative eye shape are used for the examples.

Contact lenses decrease the production of the tear film reflex due to decreased sensitivity of the ocular surface. The tear film becomes unstable due to friction between the contact lens and the surface of the eye. Decreased tear film production and increased evaporation due to contact lens wear increase the occurrence of dry eye syndrome. Case Report : Based on this study, 26 out of 41 respondents wh

Abstract:

A 52-year-old man presented with left eye blurring of vision for 4 days. He had undergone right phacoemulsification with capsular tension ring (CTR) and an extended depth-of-focus (EDOF) intraocular lens (IOL) 7 years prior. He denied trauma. The uncorrected vision in the right eye was 20/20, N5 for near, and left 20/60, N26 for near. The left eye had a phacodonetic mild nuclear sclerotic cataract with vitreous in the pupil inferior temporally (Figure 1 JOURNAL/jcrsoc/04.03/02158035-202501000-00034/figure1/v/2025-06-04T195034Z/r/image-tiff ).

Abstract:

We present a case of scleral lens surface crazing in a patient with keratoconus (KC) and chronic giant papillary conjunctivitis (GPC). A 45-year-old Asian male with known keratoconus (KC) and allergic eye disease in both eyes, who is an experienced scleral lens user, presented with a 3-month history of lens intolerance in the right eye. On examination, the right eye scleral lens showed extensive lens surface crazing with poor surface wettability. The upper tarsal conjunctiva showed conjunctival hypertrophy – active GPC. After allergy treatment and symptomatic improvement, the scleral lens was

Abstract:

Background In some situations it is necessary to use biometry from the fellow eye for lens power calculation prior to cataract surgery. The purpose of this study was to analyse the lateral differences in biometric measurements and their impact on the lens power calculation. Methods The analysis was based on a large dataset of 19,472 measurements of 9736 patients prior to cataract surgery with complete biometric data of both left and right eyes extracted from the IOLMaster 700. After randomly indexing the left or right eye as primary (P) and secondary (S), the differences between S and P eye we

Introduction: Medical professionals performing fluoroscopy guided interventional procedures in cardiology are exposed to a risk of radiation induced cataract, especially if the eye lens dose exceeds the annual dose limit of 20 mSv. Aim: The aim of the current study is to measure the eye lens exposure in three interventional cardiology departments, to analyze the relationship between patient dose and eye lens dose and to study the effectiveness of lead goggles without side protection. Material and methods: Measurements were performed in three departments with participation of 4 interventional c

Abstract:

Introduction. The causes leading to dislocation of the natural lenses are different involving injuries, hereditary diseases and spontaneous dislocation. Spontaneous dislocation of a transparent natural lens is extremely rare, especially dislocation of the anterior eye chamber. We report a case of spontaneous dislocation of the transparent natural lens to the anterior eye chamber in a patient who had no history of eye injuries. Case Outline. The patient was a 17-year old boy. Lens dislocation was spontaneous, and the patient presented for ophthalmological consultation due to a sudden vision imp

Abstract:

A 41-year-old man underwent surgery in both eyes due to diagnosed lens subluxation with significant decrease in visual acuity. In the left eye, an acute attack of angle-closure glaucoma caused by lens subluxation into the anterior chamber resulted in a combined procedure of lensectomy with posterior vitrectomy and silicone oil endotamponade due to iatrogenic retinal detachment. In the right eye, a procedure was performed to remove the subluxated natural lens with simultaneous intrascleral fixation of an artificial lens. During this procedure, the author’s “Vampire” technique was used to facili

Abstract:

Cataract iz one of the most common eye diseases among elderly people. The crystalline lens of the human eye is like a “natural lens which skips and refractors light rays. The crystalline lens is located inside the eyeball between the iris and vitreous parts of the eye. In youth the eye’s lens is transparent, elastic, can change its shape, almost instantly directing and managing its focus, this is why an eye sees the far and near objects equally good. In case of the cataract there is partial or absolute clouding of the lens, which may lead to the loss of its transparency and the eye gets only t

Previous work revealed that this mutant has a shortened body axis and eye defects including a defective hyaloid vasculature, focal corneal dysplasia, and loss of the crystalline lens. While these studies highlight the importance of lamininα1 in lens development, a detailed analysis of the lens defects seen in these mutants was not reported.
