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

Aims: To evaluate toric intraocular lens implantation and a second laser-assisted arcuate keratomy during phacoemulsification surgery in correction of moderate astigmatism. Setting The setting is a medical research study. Patients with age-related cataract and moderate preoperative corneal attmatism 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 system, a vector analysis of astigmatic changes was performed. Study findings This analysis included 75 eyes from 67 patients. In the FSAK group, mean residual refractive astigmatism at 3 months was -0. 63 u00b1 - 0. 55 D, and -0. 80 -0. 10 % D in 32 eyes and 25 eyes, respectively, and was u22641. 00 D in 32 eyes and 25 eyes. 0. 33 D in the TIOL group and 0. 48 u00b1 0. 29 D in the FSAK group, respectively, on the success index. Conclusions TIOL implantation provided better results in treating moderate astigmatism in moderate astigmatism.

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

The primary aim of this review is to investigate how Alcon's PanOptix trifocal intraocular lens was implanted in 55 cataract patients with femtosecond laser-assisted cataract surgery. Methods Fifty-five patients with cataract surgery were treated with femtosecond laser-assisted cataract surgery as well as trifocal IOL implantation. Patients at 1, 3, and 6 months after surgery were compared to those prior to surgery, showing statistical significance. All patients' surgical eyes saw a smooth transition from +0D to -2. 5D, with visual acuity of the surgical eyes reaching a higher degree than 0. 1 LogMAR, six months after the operation. Conclusions Femtosecond laser-assisted cataract surgery with trifocal IOL implantation can remove the lens from the patient with excellent visual quality and greatly raise the patient's postoperative satisfaction.

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

After cataract surgery, Aim To investigate the clinical features, causative organisms, and effects of timely vitrectomy and silicone oil tamponade without intraocular lens removal in the treatment of acute-onset endophthalmitis after cataract surgery. Methods We retrospectively reviewed the medical characteristics and microbiological factors in ten patients with APCE at Tianjin Medical University General Hospital from January 2010 to December 2018. Endophthalmitis was the onset of endophthalmitis at 2. 0 hrs. In 5 eyes, S. auus, and Enterococcus in 1 eye, Staphylococcus epidermidis was isolated in 5 eyes, S. aureus in 2 eyes, and enterococcus in one eye. Both eyes and temporary IOP elevation in one eye were common in the anterior chamber at the early stages of all eyes and temporary IOP elevation in one eye. Conclusion Under 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.

Target To determine the effect of intravitreal injection of triamcinolone acetonide and conbercept on diabetic macular edema following cataract intraocular lens surgery, we need to investigate the effectiveness and safety of diabetic macular edema. During IOL surgery, patients in the conbercept group received intravitreal injection of conbercept, and patients in the triamcinolone acetonide group were given triamcinolone acetonide during surgery. The triamcinolone acetonide group's intraocular pressure was higher than the conbercept group three months after surgery, with the corrected visual acuity of the two groups much higher than the triamcinolone acetonide group being more significant than the triamcinolone acetonide group significantly higher than the contiguous group's before. In the triamcinolone acetonide group, patients with elevated intraocular pressure, headache and vomiting, orbital swelling pain, eye swelling, and eye pain were all significantly greater than those in the conbercept group.

Accuracy of Intraocular Lens Power Calculation Formulas in Patients With Multifocal Intraocular Lens Implantation With Optic Capture in Berger Space for Pediatric Cataract.

Objective In pediatric patients with multifocal IOL implantation with optic capture in Berger, the aim of this study is to determine the validity of intraocular lens calculation formulas. Methods This prospective observational research followed 68 children aged 3 to 14 years in Berger, who received multifocal IOL implantation with optic capture from June 2019 to June 2020 in Qingdao Eye Hospital, completing the series. However, the Hoffer Q, Barrett Universal II, Holladay, Holladay2, and SRK/T formulas all had a similar success in predicting refractive error within u00b10. 50 D. For eyes with a shorter axial length or a steeper cornea, for which the Hoffer Q and Holladay2 formulas were more accurate, there was a trend toward a greater prediction error. Conclusions For patients with pediatric cataract surgery undergoing multifocal IOL implantation with optical capture in Berger space, the Hoffer Q, Barrett Universal II, Holladay, 2, and SRK/T formulas were more effective than other formulas.

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

The effects of toric intraocular lens implantation for eight years were studied after surgery. With a decrease in J 0 in eyes with pre-operative with-the-rule astigmatism, increasing J 0 in eyes with anti-rule astigmatism, raising J 0 in eyes, and correcting J 45 in eyes with oblique astigmatism, Toric IOL implantation significantly reduced pre-existing astigmatism. The eyes with preoperative ATR astigmatism improved, ATR astigmatism increased by a substantial ATR change, and J 0 at 5 and 8 years was significantly smaller than that at 1 month postoperatively. Uncorrected distance visual acuity was also significantly higher at 5 and 8 years than at 1 month postoperatively. The effects of toric IOLs on astigmatism and visual acuity were sustained for 8 years in eyes of WTR and oblique astigmatism. With preoperative ATR astigmatism, the astigmatism-correcting effects of toric IOLs decreased at 5 years and then postoperatively, indicating that overcorrection should be considered at the time of cataract surgery.

Risk Factors Associated With Intraocular Lens Decentration After Cataract Surgery.

After uneventful phacoemulsification with IOL implantation, Purpose: To determine risk factors associated with intraocular lens decentration after uneventful phacoemulsification. The vertical decentration was positively associated with the white-to-white distance and the magnitude of angle u03b1 were positively correlated with the decentration magnitude, the horizontal angle u03ba and horizontal angle u03b1 were positively related with the horizontal advancement, according to a multivariate regression report, and the anterior chamber depth and vertical angle u03ba were positively associated with the horizontal decentration. Conclusions The horizontal deposition was higher in patients with a larger horizontal distance and a wider horizontal angle u03b1, u03b1-u03b1, and a wider vertical range, although not greater in patients with a deeper anterior chamber depth and a wider vertical angle —u03ba.
