Senescence is a leading cause of age-related cataract (ARC). The current study indicated that the senescence-associated protein, p53, total laminin (LM), LMα4, and transforming growth factor-beta1 (TGF-β1) in the cataractous anterior lens capsules (ALCs) increase with the grades of ARC. In cataractous ALCs, patient age, total LM, LMα4, TGF-β1, were all positively correlated with p53. In lens epithelial cell (HLE B-3) senescence models, matrix metalloproteinase-9 (MMP-9) alleviated senescence by decreasing the expression of total LM and LMα4; TGF-β1 induced senescence by increasing the expression of total LM and LMα4. Furthermore, MMP-9 silencing increased p-p38 and LMα4 expression; anti-LMα4 globular domain antibody alleviated senescence by decreasing the expression of p-p38 and LMα4; pharmacological inhibition of p38 MAPK signaling alleviated senescence by decreasing the expression of LMα4. Finally, in cataractous ALCs, positive correlations were found between LMα4 and total LM, as well as

Normotensive candidates for cataract surgery with (study group) and without (control group) PXS were enrolled in the study. CCT ...
YAG capsulotomies are routine procedures used to restore vision after the formation of a secondary cataract, also called posterior capsular opacification.
Posterior capsule opacification (PCO) is a fairly common complication of cataract surgery. Sometimes you can develop a thickening of the back (posterior) of the lens capsule which holds your artificial lens in place.This thickening of the capsule causes your vision to become cloudy. If this happens you may need to have laser treatment to make vision clear again. Once you have had the laser treatment for PCO it doesnt normally cause any long term problem with your sight.

Purpose : Many drugs have been loaded onto IOLs by different methods to achieve a sustained and controlled release of drugs to treat posterior capsular opacification (PCO). This study tested the hypothesis that the sustained release of genistein (GEN) from negative charged nanoparticles surface modified IOL by ester bond can prevent the PCO in rabbit eyes effectively and safely.. Methods : Nanostructured lipid carriers (NLCs) loaded with GEN (GEN-NLC) were made by melt emulsification method. GEN-NLCs were attached on IOLs by ester bond formed by the dehydration between the carboxyl group offered by the sodium deoxycholate on the NLC surface and the hydroxy group of hydrophilic acrylic IOLs. The morphology and release of the GEN-NLC on the surface of IOLs and was measured. Sixty New Zealand albino rabbits undergoing phacoemulsification in left eye were randomly and equally divided into three groups. Group A: original IOL; group B: anterior chamber (AC) injection GEN-NLC and original IOL; group C: ...
Aslam and colleagues6 have presented, in the BJO, a systematic analysis of strategies to evaluate posterior capsule opacity and have pointed out that at present there is no entirely satisfactory method of comprehensively quantifying capsule opacity in vivo. In addition to regional quantitation of the optical density of capsule opacity, typically scored subjectively or by analysis of digitised photographs, capsule opacity has fibrotic and lens epithelial proliferative components that require three dimensional measurement. In order to assess the extent of opacification, researchers such as Sacu and colleagues have resorted to multiple modes of evaluation including a subjective score that ranks subtypes of fibrotic opacity, automated analysis of digitised photographs, and need for Nd:YAG laser capsulotomy.4 Hayashi and Hayashi7 have argued that multiple methods are indeed required to adequately describe these various features, and have suggested that retroillumination photography is helpful in ...
Purpose: To determine the qualitative change in stress on the lens capsule during in vivo human accommodation. Methods: Nine subjects [mean age: 30 years, range: 25-38 years] were studied, each of whom had undergone a phakic refractive intraocular lens (PRL) surgical procedure. The change, during accommodation, of stress on the surface of the anterior lens capsule (ALS) was determined by employing high-resolution anterior segment optical coherence tomography (OCT). This was done by comparing the ratio of the intensity of the image from the anterior surface of the natural lens (ALS) to the images of the anterior corneal surface (ACS), posterior corneal surface (PCS), and the posterior surface of the phakic refractive intraocular lens (PPRLS) before and during accommodation. Results: The intensities of the OCT images of the ACS and PPRLS did not significantly change during accommodation when compared to their respective baselines, while the intensity ratios: ALS/ACS, ALS/PCS and ALS/PPRLS all ...
The StabilEyes® Capsular Tension Ring provides exceptional intraoperative stability for cataract patients with zonular weakness.
A synthetic polymer (24) is provided for endocapsular lens (18) replacement in an eye (10). The polymer, whch is injected into the lens capsule (16) after removal of the lens, comprises an oxygen-stabilized photosensitive prepolymer. An example of such a prepolymer comprises polyether with urethane linkages with one or both ends capped with a functional group containing at least one double bond, such as an acrylate, a methacrylate, or a styrene. The polymerization reaction is initiated with a photoinitiator such as dimethoxyphenylacetophenone and is quenched in the presence of oxygen. Contrary to the prior art polymers, the time of curing is on the order of only a minute or so. The viscosity and thickness of the polymer formed may be tailored to achieve a desired index of refraction of between about 1.3 and 1.6.
Abstract: : Purpose: Our aim is to covalently modify intraocular lens implants (IOLs) with death receptor ligands to induce apoptosis in contacting lens epithelial cells (LECs). The clinical goals are prevention of posterior capsular opacification (PCO) and preservation of normal capsule tissue compliance for accommodating IOLs. We have previously demonstrated that primary LECs on lens capsule are resistant to Fas stimulated apoptosis; whereas HLE-B3 LECs are sensitive to Fas ligation when cultured on tissue culture plastic but become Fas resistant when cultured on lens capsule or collagen IV. Here we determine whether Fas ligand modified surfaces can induce apoptosis in LECs using conditions under which they are Fas sensitive. We also initiate exploration of the mechanism of Fas resistance for primary LECs adherent to capsule. Methods: Prototype surfaces were constructed by coupling Fas ligand (FasL) via heterobifunctional polyethylene glycol (PEG) chains to hydroxyethyl methacrylate (HEMA). ...
A common cataract surgery complications is a posterior capsule opacity in the lens implant. A procedure called a YAG laser capsulotomy can quickly and effectively restore vision following posterior capsular opacification.
The scleral pigment, best seen temporal, is found in all affected individual in this bilateral disease. The dark iris is not visible due to the dilated pupil. Pigment can be seen on the anterior lens capsule (black arrows). The pigment and scar on the axial cornea is due to exposure keratitis secondary to buphthalmia. Intraocular pressure at this time was 22mmHg.. ...
We will demonstrate several exercises to stretch out the tight posterior capsule after covering causes of a tight posterior capsule.
Discussion. In the rat lens explant model used in the present study explants cultured with TGFβ then FGF without addition of DEX exhibited many features of PCO development over the 30 day culture period, as reported previously [10]. Cells became multilayered and tended to gather up into plaques, leaving the surrounding lens capsule denuded. These plaques, which arose quite abruptly from the lens capsule, were covered with a thick web of ECM-like material. In addition, cells underwent epithelial-mesenchymal transition, as evidenced by expression of α-smooth muscle actin and fibronectin, non-lens proteins that are typically associated with human PCO.. In this model, significant changes in lens cell behavior occurred when DEX was included throughout the culture period. These included rapid formation of long, needle-like cells early in the culture period and a reduction in the overall extent of thickening of the explant over time, which was associated with a decreased tendency for the lens capsule ...
The pathological development of lens epithelial cells (LECs) leads to posterior capsular opacification (PCO). This studywas undertaken to investigate the effects of microRNA-486-5p (miR-486-5p) on TGF-b2-induced proliferation, invasionand epithelial-mesenchymal transition (EMT) in the lens epithelial cell line SRA01/04, and to explore the underlyingmolecular mechanisms. The expression of miR-486-5p in TGF-b2-induced SRA01/04 cells was down-regulated, and theexpression of Smad2, p-Smad2 and p-Smad3 was up-regulated. A dual-luciferase reporter assay revealed that miR-486-5pdirectly targets the 30-UTR of Smad2. MiR-486-5p mimic transfection markedly down-regulated the expression levels ofSmad2, thus inhibiting the expression of p-Smad2 and p-Smad3. MiR-486-5p overexpression in SRA01/04 cells markedlysuppressed TGF-b2-induced proliferation and invasion, inhibited protein expression of CDK2 and CDK4, down-regulatedfibronectin, a-SMA and vimentin and up-regulated E-cadherin; these effects were partly ...

0081] Mirror M2 serves to direct the light onto the target, and may be used in a variety of ways. Mirror M2 could be a dichroic element that the user looks through in order to visualize the target directly or using a camera, or may be made as small as possible to provide an opportunity for the user to view around it, perhaps with a binocular microscope. If a dichroic element is used, it may be made to be photopically neutral to avoid hindering the users view. An apparatus for visualizing the target tissue is shown schematically as element V, and is preferably a camera with an optional light source for creating an image of the target tissue. The optional aiming beam AIM may then provide the user with a view of the disposition of the treatment beam, or the location of the identified targets. To display the target only, AIM may be pulsed on when the scanner has positioned it over an area deemed to be a target. The output of visualization apparatus V may be brought back to the system via the ...

The purpose of this study is to examine the efficacy of a capsular tension ring (CTR) in preventing anterior capsule shrinkage after cataract surgery in exfoliation syndrome (XFS) with no zonular weakness. The eyes with XFS undergo phacoemulsification and aspiration (PEA) with an intraocular lens (IOL) implantation. All operations are performed by a single surgeon. No eyes with either ectopia lentis or phacodonesis are included. There are three groups; CTR is not used in group A, CTR is simply implanted in group B, and CTR is implanted and closed by tying both eyelets in group C. The areas of continuous curvilinear capsulorhexis (CCC) are calculated, and both the time-course change and the comparison among the 3 groups are tested ...
Posterior capsular opacification (PCO) caused by proliferation of residual epithelial cells over the lens equator and onto the posterior lens capsule [1] is the leading cause of visual impairment and blindness after cataract surgery [2-4]. There are currently no effective means by which to eradicate the residual lens epithelial cells during the operation [5,6]. In spite of improvements in the basic research on development of cataracts, surgical techniques, and the material or the design of the intraocular lens, the incidence of PCO is still 8~34.3% in adults, and nearly 100% in children [7-10]. One new promising approach for treatment of PCO is a gene therapy system uses a so-called suicide gene, the herpes simplex virus type 1 thymidine kinase (HSV-tk) gene, and the anti-herpes nucleoside analog drug, ganciclovir (GCV) [11-13]. In this system, GCV is phosphorylated by HSV-tk into a deoxynucleotide analog that becomes incorporated into DNA during strand replacement in proliferating cells, where ...
0024]Typically the human lens capsule of the present invention may be supported on a solid substrate such as a plastics or glass surface, e.g. the surface of a petri dish. Sigma ligands may be first identified as such by conducting, for example, a radioligand binding assay, such as described in WO 00/00599 to ascertain that the test agent is a sigma ligand, before carrying out the method as described above. Importantly, sigma radioligand binding assays determine only that an agent binds to sigma sites and not whether it acts as an agonist or antagonist in functional terms (whether it acts to stimulate or inhibit the receptor). In WO 00/00599 it was disclosed that different sigma receptor subtypes--or even binding pockets on the same receptor molecule--can act in opposite ways to either promote or suppress apoptosis (cell death). Given that a number of sigma ligands bind to both sigma-1 and sigma-2 sites (that act in opposition to regulate cell death), the balance of their functional activities ...
Ocular lens tissue mechanics: Understanding the mechanics of lens accommodation (ability of the eye dynamically to focus near to far, or far to near) can assist in the diagnosis of early presbyopia as well as in the development of new potential clinical treatments and intraocular lens (IOL) design and implantation strategies. Related to the mechanism of focusing, presbyopia is an ocular disease that stems from age-related loss of lens accommodation leading to loss of focusing range and near vision. This is attributed to changes in ciliary muscle function, as well as changes in the elastic and deformable properties of the lens substance and the lens capsule. The precise relationship of these changes, however, is not well described. During cataract surgery, the process of removing a circular portion latitudinally of the anterior lens capsule can lead to tearing of the capsule longitudinally, propagating to the posterior capsule and loss of the full lens and zonules. A fundamental understanding of ...
Cataracts are a degenerative change of the lens, resulting in an opacity and interference with optical clarity and vision. Cataracts are the most common cause of blindness in dogs. Surgical removal of the cataract and replacement with an artificial intraocular lens implant (IOL) restores vision. The leading complication of cataract surgery in dogs and humans is posterior capsular opacification (PCO), a hazy opacity of the lens capsule developing post-operatively that results in diminished vision. This is treated with laser surgery in humans which cannot be performed in dogs. Therefore, an alternative method for preventing or decreasing PCO must be found. A capsular tension ring (CTR) is a device that can be placed within the lens capsule, with the IOL, at the time of cataract surgery. Previous studies in humans have shown that CTRs significantly decrease PCO formation. We hypothesize that CTRs will significantly diminish PCO formation in canine lenses using an ex vivo model and in clinical canine

Cataract surgery is a very common procedure with low risks involved. Less than a single percent of patients will suffer from any serious complications that will necessitate further surgeries. If complications do arise, these are, more often than not, successfully treated through additional procedures.. While it is possible that your vision may get worse or that permanent damage may occur after the cataract surgery, these cases are extremely rare. Still, a comprehensive consultation with your eye doctor should be done so that you will be fully informed of all the possible risks.. Posterior Capsule Opacification. The most common risk that a cataract patient may encounter after surgery is the development of a condition called posterior capsule opacification, or PCO. In this condition, a portion of the capsule of your lens may thicken and lead to a cloudy vision. While some may mistake this as a sign of the cataract returning, it is actually cells growing at the back of the artificial lens.. This is ...
The present invention relates to an intraocular lens, including a flexible capsule adapted to be inserted into the natural lens capsular bag. A polymerized portion is positioned within the flexible capsule, and an unpolymerized material is located within the flexible capsule, and has loose monomers and a polymerization initiator so that the unpolymerized material changes its volume when exposed to an energy source.
Three variants on the human in vitro capsular bag model were employed. The first was used to assess an open bag IOL (Anew Zephyr™); this involved using the bag-zonular-ciliary body complex isolated from human donor eyes and attached to a silicone ring. A capsulorhexis and lens extraction were performed, and an Alcon Acrysof IOL or Anew Zephyr™ IOL implanted in to the suspended capsular bags. To assess cell growth in different medium volumes (1.5 versus 6mL) we employed a non-suspended human capsular bag model in which the bag is isolated from the ciliary body and secured to a culture dish with pins. We further adapted the capsular bag system, such that radial incisions were made in the anterior capsule, which was then folded back and secured to a dish (a fully open bag model). Cell growth was observed by phase-contrast microscopy and quantified using ImageJ software. Growth factor levels were detected by ELISA ...

Is your vision blurry, especially at night or in very bright light? It could be an early symptom of cataracts. A cataract is a clouding of the lens of the eye that interferes with clear vision. Unlike a healthy, transparent lens, which focuses light rays precisely onto the retina, a lens clouded by a cataract loses its ability to focus light rays. The light that reaches the retina is scattered and diffuse, causing blurry vision. The amount of vision impairment depends on the size and density of the cataract and where it is located in the lens: the nucleus, cortex, or posterior lens capsule. A cataract in the periphery of the cortex, for example, has little effect on vision because it does not impede the passage of light through the center of the lens. On the other hand, a dense nuclear cataract causes severe blurring, interfering primarily with distant vision (at first). A cataract that develops in the posterior capsule has a greater effect on near vision and also causes sensitivity to glare. ...
Posterior Capsule Opacity is NOT a result of a complication during or from your cataract surgery. It is however an unavoidable after effect of cataract surgery. It is easily treated and the vision in most cases is restored; as long as there is no other associated ophthalmic pathology.. The natural lens in the eye that forms a cloudy image known as a cataract sits inside what is called a capsule . The capsule is elastic in form and shrinks tightly around the lens. During cataract surgery the lens is removed through a small incision in the front of the lens capsule and vacuumed out and the new intraocular lens is put in its place. The capsule then wraps around it neatly, avoiding the need for sutures. Inside the lens are epithelial cells that continue to grow at a minute rate from the time our eyes form as a foetus. During cataract surgery these cells are removed with the cloudy lens, however it is unavoidable that some of the microscopic cells may remain. It is these epithelial cells that form ...
Six rabbits underwent phacoemulsification with bilater implantation of an IOL. Postoperative power adjustment was performed using the femtosecond laser 2 weeks following implantation, in one eye. The animals were then followed clinically with slit lamp examination for an additional 4 weeks. The rabbits were then euthanized and the globes were enucleated. The globes were bisected coronally and gross examination and photographs from the posterior aspect were performed to assess anterior capsular opacification and fibrosis as well as posterior capsular opacification. After IOL explantation for power measurements, the globes were sectioned and processed for light microscopy following H&E staining ...

Cataract surgery is one of the most common surgical procedures performed in the United States, and it has one of the highest success rates of any surgery. However, there are cases after cataract surgery where the patient is still experiencing cloudy vision. This may develop weeks or even months after successful surgery.. This cloudiness is not uncommon, and it can be corrected using a procedure called Posterior Capsulotomy.. The lens of your eye has a cellophane-like outer lining called the capsule. During cataract surgery, the natural lens in the eye is removed, but great care is taken to keep the capsule in place to hold the replacement artificial (intraocular) lens.. Sometimes after surgery, the posterior capsule (located behind the implanted intraocular lens) can become cloudy, causing some loss of vision. When this happens, your ophthalmologist performs a Posterior Capsulotomy to reduce the obstruction.. The procedure is often called a YAG Laser Treatment, after the name of the instrument ...

The developing lens is a powerful system for the study of tissue interactions and also the target of the medically important ocular disease cataract, a lens opacity that affects over 25 million individuals and is the leading cause of blindness worldwide (Asbell et al., 2005; Hejtmancik, 2008). The mature lens consists of two polarized cell types: a monolayer of lens epithelial (LE) cells and a mass of elongated and aligned lens fiber (LF) cells. The entire structure is covered by a lens capsule, a thick basement membrane secreted by LE and early LF cells in a polarized manner (Wederell and de longh, 2006). During development, the lens originates from a thickening of the head ectoderm that invaginates to form the lens pit, and then detaches to form the lens vesicle. Cells from the anterior lens vesicle differentiate into epithelial cells, while cells from the posterior lens vesicle elongate to form primary fiber cells. In later embryogenesis, LE cells continuously proliferate and differentiate ...

Ideally, the capsulorhexis diameter should be slightly smaller than the optic diameter so that we can achieve 360° overlap. But what if it doesnt? Well, it turns out that it is not that big of an issue because the capsule shrink-wraps in the post-op period and it makes the capsulorhexis diameter about 10% smaller --…
Researchers began by looking at the properties of lens epithelial stem cells (LECs). These are cells that regenerate replacement lens cells as a person ages, but this process slows as a person gets older. They wanted to see which genes controlled how they developed into fully formed lens cells. After establishing that LECs had the potential to regenerate lenses, they started developing their surgical technique on young animals - firstly using rabbits, then macaque monkeys. When they had shown that both animals could regenerate complete, working lenses from the LECs that remained in a largely intact lens capsule, the researchers carried out the surgery on 12 children (24 eyes). They then compared the results to 25 children (50 eyes) treated with the conventional method. The surgery was carried out as a randomised controlled trial, with children randomly allocated to either the new operation or the standard method. The new operation involved making much smaller cuts in the lens capsule (about 1 to ...

The lens capsule is a component of the globe of the eye. It is a clear, membrane-like structure that is quite elastic, a quality that keeps it under constant tension. As a result, the lens naturally tends towards a rounder or more globular configuration, a shape it must assume for the eye to focus at a near distance.. ...
Cataract surgery is performed under a full general anaesthetic and a muscle relaxant is given so that the eye comes into the correct position for the operation. This means that a ventilator needs to be used to inflate the chest during the procedure. We monitor your dog very carefully throughout the surgery using very modern sensitive equipment and the staff involved are specially trained in the procedure. This helps to reduce the risks of the anaesthetic to a very low level.. The operation is very delicate and involves the use of an operating microscope and tiny instruments. Two small cuts are made in the window of the eye (the cornea), near where the coloured part (the iris) joins the white part.. The lens is just behind the iris and lies in a delicate bag of tissue called the capsule. After the eye has been filled with a special gel called a viscoelastic, some of the lens capsule is taken out. The gel which is used helps to inflate the eye and protect the structures inside it from the effects ...

A remotely operable ocular surgical cutting instrument (10), useful, for instance as a knife for a capsulotomy procedure, has a two portion main body (12) with one portion (16) oriented at an angle with respect to the other (14). A turning unit (20) extends through the main instrument body (12), and, to constitute a capsulotomy knife, a cutting blade (22) is mounted on the turning unit (20) at one end of the body (12). During operation, the orientation of cutting edge of the blade (22) with respect to the instrument body (12) is determined by manipulation of the opposite end of the turning unit at the other end of the instrument body (12).
