Symfony and vivity: comparing two EDOF IOLs
This prospective, randomised, double-masked, single-surgeon study compared the visual outcome between two commonly used extended depth of focus (EDOF) lenses, the Tecnis Symfony IOL (Johnson & Johnson Vision) and the Acrysof IQ Vivity IOL (Alcon Laboratories, Inc.). Sixty-nine patients underwent...
Surgically induced astigmatism after cataract surgery
In this study, the authors analysed a dataset of 122 eyes of 122 patients with pre- and postoperative measurements of corneal astigmatism with IOL Master 700. A standardised 2.5mm superior corneal incision was utilised. The corneal power vector component in...
The rate of realignment of two toric monofocal intraocular lenses (IOL)
This retrospective study used the American Academy of Ophthalmology Registry data to analyse the need of reoperation for realignment within the first year after cataract surgery with a TECNIS or AcrySof monofocal toric IOL implanted during 2016 and 2017. They...
Are any precautions needed when performing cataract surgery in thrombocytopenic patients?
In this retrospective multi-centre study, charts for 196 eyes of 150 thrombocytopenic patients were reviewed. The mean preoperative platelet level was 73.0 ± 20.5 × 103/μL (median of 76.0 × 103/μL), with a range of 17 to 100 × 103/μL...
Comparing tensile strengths of two scleral fixated intraocular lenses: CT-Lucia and MA60
The authors designed a benchtop model to measure the tensile strengths and resistance to breakage of the haptics and haptic-optic junctions of the CT Lucia 602 (Carl Zeiss, California) and AcrySof MA60 (Alcon Laboratories, Texas) IOLs. For the haptic breakage...
IOL power in short eyes
Prospective analysis of 269 eyes of 269 patients between 2017 and 2020, with axial length (AL) of 22mm or less. New principles for calculating IOL power were recently developed, including formulas based on paraxial ray-tracing (Barrett and Olsen) and based...
Corectopia grading
The authors present a novel corectopia classification system using 28 eyes of 28 patients with or without corectopia. The grading and classification system for corectopia was as follows: (i) Direction of decentration: superior (DecS), superonasal (DecSN), nasal (DecN), inferonasal (DecIN),...
Complications after cataract surgery in high myopes: a systematic review and meta-analysis
The authors review all the modern literature on complications after phacoemulsification in high myopes with axial lengths (AL) greater than 25.0mm. Twenty-eight studies reporting on 19,586 eyes were included. The corrected distance visual acuity (CDVA) improved from 0.96 ± 0.53...
Posterior capsular rupture risk factors as reported in the European registry
In this cross-sectional review of the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO) including 2,853,376 patients and 31,749 cases with posterior capsular rupture (PCR), the authors observed a trend of reduction in PCR rate from 1.44%...
Dead bag syndrome: a new and rare cause of late IOL dislocation
The dead bag syndrome has recently been described as a cause of late spontaneous intraocular lens (IOL) subluxation and / or dislocation. The capsular bag remains clear years after surgery and then becomes diaphanous and floppy. The authors explanted seven...
The posterior capsular rupture rate post COVID-19 pandemic
In this retrospective single centre consecutive case series, the authors investigate the effect of suspending elective cataract surgery during the COVID-19 pandemic for a period of 19 weeks. They divided the study period, September 2019 to January 2021, into three...
Clinical outcomes of a supplementary sulcus IOL
In this retrospective study, the authors examined 31 eyes of 20 patients who had received a supplementary trifocal sulcus IOL in addition to a ‘bag-in-the-lens’ IOL. Implantation of a ‘bag-in-the-lens’ IOL requires the creation of anterior and posterior capsulotomies, followed...
