Toric intraocular lens implantation vs femtosecond laser-assisted arcuate keratotomy for correction of moderate astigmatism in cataract surgery.

Purpose Objectivity Objectives: During phacoemulsification surgery in correction of moderate astigmatism, we could assess toric intraocular lens implantation and femtosecond laser-assisted arcuate keratomy. Setting Theme of a clinical research study. Patients with age-related cataract and moderate preoperative corneal atrestation of 1. 25 to 3. 0 diopters were randomized into a TIOL implant group and an FSAK group with matched corneal arcuate keratomies. Using the Alpins vector method, vector analysis of astigmatic changes was carried out. Findings This review included 75 eyes from 67 patients. In the FSAK group, the mean residual refractive astigmatism at three months was -0. 63 u00b1 0. 55 D in the TIOL group and -0. 90 -0. 63 0. 0 D, respectively, in 32 eyes and 25 eyes. Conclusions: TIOL implantation provided improved results in treating moderate astigmatism. Despite this, FSAK has been shown to be a safe method for reducing astigmatism.

Observation of Visual Quality after Femtosecond Laser-Assisted Cataract Surgery Combined with Trifocal Intraocular Lens Implantation.

The aim of this review is the first report of Alcon's Panoptix trifocal intraocular lens implanted in 55 cataract patients with femtosecond laser-assisted cataract surgery. Methods Fifty-five patients with cataract were treated with femtosecond laser-assisted cataract surgery as part of trifocal IOL implantation. Patients with uncorrected near visual acuity, uncorrected intermediate visual acuity, and uncorrected distance visual acuity of patients at 1, 3, and 6 months after surgery were compared to those before surgery, showing statistical significance. All patients' surgical eyes saw a smooth transition from +0D to -2. 5D, with visual acuity of the surgical eyes at a level higher than 0. 1 LogMAR. Conclusions Femtosecond laser-assisted cataract surgery with trifocal IOL implantation can erase the lens from the patient with high visual quality and greatly raise the patient's postoperative satisfaction.

Intraocular lens removal or not during vitrectomy for acute infectious endophthalmitis after cataract surgery.

In this case, Guo et al wrote a story titled "Timely vitrectomy without intraocular lens removal for acute endophthalmitis after cataract surgery" in order to stimulate further discussion.

Timely vitrectomy without intraocular lens removal for acute endophthalmitis after cataract surgery.

Aim To investigate the clinical characteristics, causative organisms, and effects of prompt vitrectomy and silicone oil tamponade without intraocular lens removal in the treatment of acute-onset endophthalmitis following cataract surgery. Methods We retrospectively reviewed the clinical characteristics and microbiological factors in ten eyes of ten patients with APCE at Tianjin Medical University General Hospital from January 2010 to December 2018. Endophthalmitis was the onset of endophthalmitis, according to the mean time between cataract surgery and the onset of endophthalmitis. In 5 eyes, S. aurania, and Enterococcus in 1 eye, the epidermidis was isolated, and Enterococcus was in 1 eye. In the anterior chamber at the early stages of all eyes and temporary IOP elevation in one eye, the most common operative difficulties were fibrin exudates in the anterior chamber, mainly due to fibrin exudates in the anterior chamber, as well as temporary IOP elevation in one eye. APCE is a safe and effective treatment for APCE, thanks to systemic antibiotic therapy and prompt diagnosis, vitrectomy, and silicone oil tamponade without IOL removal.

Recent Advances of Intraocular Lens Materials and Surface Modification in Cataract Surgery.

Advances in cataract surgery have increased the need for intraocular lens materials, which have raised the demand for intraocular lens materials. The purpose of this report is to summarize the scientific progress of pertinent IOL materials classified according to various scientific goals. The manufacture of IOL products is often based on the common IOL materials on the market, such as silicon and acrylate.

Efficacy and Safety of Intravitreal Injection of Triamcinolone Acetonide and Conbercept for Intraocular Lens after Cataract Surgery.

After cataract intraocular lens surgery, the aim of this study was to investigate the impact of intravitreal injections of triamcinolone acetonide and conbercept on the efficacy and safety of diabetic macular edema. Methods and Results In our hospital from January 2017 to July 2021, we randomly divided into a conbecept group and a triamcinolone acetonide group with a total of 350 patients with cataract edema. Patients in the condens group received intravitreal injection of conbercept during IOL surgery, and patients in the triamcinolone acetonide group received a triamcinolone acetonide regimentoni group were given an injection of triamcinolone acetonide during surgery. The triamcinolone acetonide group's intraocular pressure was much higher than the conbercept group's three months after treatment, with corrected visual acuity of the two groups much higher than the triamcinolone acetonide group significantly higher than the congenital group's.

Long-term outcomes of cataract surgery with toric intraocular lens implantation by the type of preoperative astigmatism.

The surgical outcomes of toric intraocular lens implantation for eight years, despite surgery findings being studied. IOL's implantation reduced pre-existing astigmatism by lowering J 0 in eyes with preoperative with-the-rule astigmatism, increasing J 0 in eyes with anti-rule astigmatism, and correcting J 45 in eyes with oblique astigmatism. After surgery, the eyes with preoperative ATR astigmatism revealed a significant ATR decrease, and J 0 at 5 and 8 years was significantly smaller than that at 1 month postoperatively. Uncorrected distance visual acuity was also significantly worse at 5 and 8 years than at 1 month postoperatively. For eight years, WTR and oblique astigmatism were two of the effects of toric IOLs on astigmatism and visual acuity. SN6AT3-8 : The long-term astigmatism-correcting results did not differ among the toric IOL used in this study, toric IOL.

Risk Factors Associated With Intraocular Lens Decentration After Cataract Surgery.

After uneventful phacoemulsification with IOL implantation, Purpose: To determine risk factors connected with intraocular lens decentration after uneventful phacoemulsification with IOL implantation. The magnitude and direction of IOL increase relative to the visual axis center were determined one month afteroperatively, and vertical and horizontal decentration figures were determined. To determine the relationship between the IOL decentration and ocular biometric variables, multivariate linear regression experiments were used. Conclusions The vertical deviation in patients with a greater horizontal clearance and a wider horizontal angle u03b1 was higher in patients with a larger horizontal resolution and a greater horizontal angle u03b1 than in patients with a higher anterior chamber depth and a wider vertical angle u03b1.

Pediatric Cataract Surgery: Rate of Secondary Visual Axis Opacification Depending on Intraocular Lens Type.

Primary intraocular lens implant in children and children's research findings are needed to determine the time course of secondary visual axis opacification leading to additional surgery. Primary IOL implantation, primary IOL implantation, single-center, retrospective review of children aged 1 to 14 years who underwent cataract surgery from primary IOL implantation. In-bag IOL placement with primary posterior capsulotomy and anterior vitrectomy (IOL) or bag-in-lens IOL placement was chosen. Primary IOL implantation measured The rate of recovery without VAO was low without VAO, but it required clearing of the visual axis after cataract surgery with primary IOL implantation. Of these, 1 eye had a 3-piece in-bag IOL, ten eyes had 1-piece in-bag IOLs, and two eyes had bag-in-lens IOLs. Compared to 3-piece acrylic in-bag IOLs, the adjusted hazard ratio was 32. 8 for 1-piece acrylic IOLs and 19. 6 for bag-in-lens IOLs. Children with secondary VAO who required a surgical procedure to clear the visual axis generally appeared within 15 months.
