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

Purpose Objectives To determine whether or not toric intraocular lens implantation and femtosecond laser-assisted arcuate keratomy during phacoemulsification surgery for moderate astigmatism correction. Setting The purpose of a clinical research study is based on a qualitative research study. Patients with age-related cataract and moderate preoperative corneal attigmatism of 1. 25 to 3. 0 diopters were randomized into a TIOL implant group and an FSAK group with matched corneal arcuate keratomies. Findings This study included 75 eyes from 67 patients. According to our charts, -0. 63 0. 00 D in the TIOL group and -0. 90 -0. 10 - 0. 53 D in the FSAK group and -3. 53 D in 32 eyes and 25 eyes respectively, respectively. In the FSAK group, the index of achievement was 0. 32. 33 D in the TIOL group and 0. 48. . 0. 29 D. Conclusions TIOL implants showed promising 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 research is the first glimpse of Alcon's PanOptix trifocal intraocular lens implanted in 55 cataract patients with femtosecond laser-assisted cataract surgery. Methods Forty-five patients with cataract surgery 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 six months after surgery were compared to those before surgery, showing statistical significance. Both patients' surgical eyes underwent a smooth transition from +0D to -2. 5D, with the surgical eyes' visual acuity reaching a level higher than 0. 1 LogMAR. Conclusions Femtosecond laser-assisted cataract surgery with trifocal IOL implantation can remove the lens from the patient's with excellent visual quality and greatly raise the patient's postoperative mood.

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

Aim To investigate the clinical characteristics, causative bacteria, and effects of timely 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 is the onset of endophthalmitis and cataract surgery in the United States. The mean time between cataract surgery and the onset of endophthalmitis was 2. 0d. The visual acuity of nine eyes increased in nine eyes after vitrectomy, but it was unchanged in one eye. In 5 eyes, S. aurora in two eyes, and Enterococcus in one eye, Staphylococcus epidermidis was isolated in 5 eyes, with Staphylococcus epidermidis isolated in 5 eyes, S. audermidis in 2 eyes, and Enterococcus in 1 eye. APCE can be treated with systemic antibiotic therapy and prompt diagnosis, vitrectomy, and silicone oil tamponade without IOL removal is a safe and effective treatment for APCE.

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

Methods The conbecept group and the triamcinolone acetonide group were randomly divided into the conbecept group and the triamcinolone acetonide group in our hospital from January 2017 to July 2021. During IOL surgery, patients in the conbercept group were given an intravitreal injection of conbercept during IOL surgery, and patients in the triamcinolone acetonide group were given a drip of triamcinolone acetonide prior to surgery. Results Three months after treatment, the best-corrected visual acuity of the two groups was significantly higher than that of the triamcinolone acetonide group, and the triamcinolone acetonide group's intraocular pressure was higher than the conbecept group's, according to the authors. Patients with elevated intraocular pressure, headache, and vomiting, orbital swelling pain, eye swelling, and eye pain, and eye pain in the triamcinolone acetonide group were significantly greater than those in the conbercept group.

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

The results of toric intraocular lens implantation for eight years after surgery were determined were not analyzed. Pre-existing astigmatism, decreasing J 0 in eyes with preoperative with-the-rule astigmatism, increasing J 0 in eyes with anti-the-rule astigmatism, and correcting J 45 in eyes with oblique astigmatism were all reduced by implantation. After surgery, the eyes with preoperative ATR astigmatism showed a dramatic ATR increase, and J 0 at 5 and 8 years was much 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, and it was also much worse at 5 and 8 years than at 1 month postoperatively. The effects of toric IOLs on astigmatism and visual acuity were sustained for eight years in eyes with WTR and oblique astigmatism. Toric IOLs reduced in eyes with preoperative ATR astigmatism, astigmatism-correcting results decreased at 5 years and later postoperatively, indicating that overcorrection should be considered at the time of cataract surgery.
