Cataract Surgery Results of New Lens Implantation “Synthesis”

The cataract surgery visual results and benefits of intraocular lens Synthesis SIPY are reviewed by an author. The lens is introduced in cartridge under factory sterile conditions that exclude the contact between lens and environment, minimize the chance of incorrect inserting of the lens in cartridge following pinching by the cartridge flaps, and eventual tearing away, leading to the haptic tearing off. Position of cartridge centralizes the cartridge tunnel for the Accuject Pro injector plunger, minimizing the likelihood of pinching the rubber tip of the IOL haptic plunger during implantation. The Synthesis SIPY lens's benefits include: factory installation of the lens inside the cartridge and Accuject Pro injector compatibility; Accuject Pro injector compatibility ensures injury to the IOL; Implantation of the Synthesis SIPY lens is also possible through the 1. 6 mm corneal tunnel; maximum photographic results can be obtained with high diopter ranges from -10. 0D to +40. 0D.

Long-term rotationalstability of AcrySof IQ Toric intraocular lens in cataract patients with myopia: a retrospective case series study

Abstract Purpose: The objective of this paper is to investigate the long-term rotational stability of AcrySof IQ Toric intraocular lens in cataract patients with myopia. 120 eyes of 78 cataract patients with axial length 24 mm, corneal astigmatism u2265 1. 50 D, and the introduction of AcrySof IQ Toric IOL by the Version navigation device were all collected. According to the AL, they were referred to two groups: group A, 60 eye with high myopia; and group B, 60 eyes with low to moderate myopia.

TGF-β/Smad Signalling Activation by HTRA1 Regulates the Function of Human Lens Epithelial Cells and Its Mechanism in Posterior Subcapsular Congenital Cataract

Children worldwide, congenital cataract is the most common cause of blindness. Patients with posterior subcapsular cataracts in the central visual axis can have a longer-sighted vision and a stimulus deprivation amblyopia. This research aims to investigate the role and mechanism of HTRA1 in human lens epithelial cells' functional regulation and production. Compared to normal controls, HTRA1 was significantly reduced in the lens capsules of children with PSC. The downregulation of HTRA1 in primary HLECs could promote HLEC formation and migration by stimulating the TGF-u03b2/Smad signalling pathway, which in turn can also influence the TGF-u03b1/Smad downstream target genes FN1 and u03b1-SMA. HTRA1 was significantly downregulated in children with PSC, and the downregulation of HTRA1 by TGF-u03b2/Smad signaling pathway, which resulted in PSC development and migration of HLECs.

Surgical Outcome of Intraocular Lens Implantation in Children with Bilateral Developmental Cataract

Purpose: To investigate the visual effects and long-term effects of intraocular lens transplantation in children with bilateral developmental cataracts, along with primary posterior capsulectomy and anterior vitrectomy. Methods: This retrospective review was conducted on the 48 eyes of 24 children who had undergone cataract surgery under general anesthesia in 48 children. Primary posterior capsule capsulectomy, primary in-bag intraocular lens implantation, irrigation-aspiration of lens debris, and anterior vitrectomy were among the primary patients treated during primary posterior capsulectomy. Visual acuity was measured in 6 months after best corrected visual acuity was established, and intraocular pressure, anterior chamber angle, optical disc, and peripheral retina were evaluated. In 33% eyes, the postoperative best corrected visual acuity were 6/6 in 10. 4% eyes, 6/9-6/18 in 63%, and 6/18 in 33% eyes. In 44 eyes, the anterior chamber angle was normal. In the companion eye, the most common cause of diminished vision was amblyopia in the same eye due to delayed surgery. Conclusion: Amblyopia is the most common cause of decreased visual recovery in children after cataract surgery.

Effects of Binahong (Anredera cordifolia (Tenore) Steenis) Extracts on the Levels of Malondialdehyde (MDA) in Cataract Goat Lenses

The aim of this research was to determine the effects of binahong leaf extract on the amounts of MDA in a goat lens coated with cataract-induced tissue. As many as possible, 40 goat eye lenses were divided into several groups, including group I standard lenses as controls, group III lenses with glucose 55 mM+ binahong leaf extract, group IV lens with glucose 55 mM + binahong leaf extract, and group V lens with glucose 55 mM+ quercetin. The lens group with the addition of binahong extract had greater results transparency than lens groups caused by glucose levels in 55 mM, according to the study's findings.

Tryptophan and Non-Tryptophan Fluorescence of the Eye Lens Proteins Provides Diagnostics of Cataract at the Molecular Level

In accord with the increasing optical density in the lens nucleolus, fluorescence intensity profiles measured along the optical axis of human eye lens age-related nuclear cataract demonstrated an increasing peak of fluorescent PTM towards the lens center. Fluorescence of Trp, its derivatives, and argpyrimidine can be excited at the red edge of the Trp absorption band, which allows normalization of the emission spectra of these PTMs to Trp's fluorescence intensity to determine semi-quantitatively their concentration.
