Randomised trial of multifocal intraocular lens versus monovision

The authors report on a randomised, multicentre clinical trial comparing the outcomes of Tecnis ZM900 diffractive multifocal intraocular lenses (IOL) versus monovision with Akreos AO monofocal IOL (dominant eye targeted for emmetropia and non-dominant eye targeted for -1 to -1.50...

Endothelial keratoplasty (EK) with anterior chamber intraocular lens (ACIOL) versus secondary posterior chamber lens (PCIOL)

This is a retrospective study of 82 eyes (23 ACIOL, 59 PCIOL) with a history of either pseudophakic (PBK) or aphakic (ABK) bullous keratopathy, who had descemet stripping automated endothelial keratoplasty (DSAEK) with retained or secondary ACIOL, or DSAEK with...

Influence of overall intraocular lens diameter on rotational stability

It has been shown that approximately one in three patients undergoing cataract surgery have >1.0D corneal astigmatism and managing this during surgery is important to achieve good refractive outcomes. One of the widely used ways of reducing preoperative astigmatism during...

Outcomes with small aperture IOLs

This study aimed to compare the clinical outcomes following the implantation of an extended depth of focus small-aperture intraocular lens (IOL) (IC-8; AcuFocus, Irvine, CA) for presbyopia correction when implanted monocularly or binocularly. Visual outcomes, defocus curve, patient satisfaction, and...

The results of the last survey Jun21

Thank you so much again for participating in the survey. I have been asked to give several talks at regional teaching sessions about some of the issues I discuss in these articles and I am happy to continue to do...

A comparative evaluation of a new diffractive trifocal and EDOF IOLs

This study aimed to compare the outcomes of two diffractive trifocal intraocular lenses and one extended depth of focus (EDOF) intraocular lens (IOLs). This was a six month, single centred, prospective, randomised, comparative study in which patients who underwent routine...

Jun/Jul 2014 Quiz

History An 80-year-old male had a cataract removed with intraocular lens (IOL) seven years previous. He presented with cloudy vision and it was noted that the IOL was intrinsically opaque. The IOL was replaced and sent for ophthalmic pathology assessment....

Outcomes for congenital vs. developmental cataract surgery

This study retrospectively reviewed follow-up data (minimum one year) to evaluate ocular outcomes and the potential factors affecting visual acuity after foldable intraocular lens (IOL) implantation in preschool childhood (up to six years) with bilateral cataract. The study included 43...

Wrong intraocular lens events – what lessons have we learned?

Data from wrong IOL patient safety incidents (PSIs) submitted to the National Reporting and Learning System (2010–2014) were reviewed and scrutinised by thematic analysis and compared with the historical data collected for groups in 2003-2010, prior to the mandatory checklist...

Surgical treatment of high myopia

Although several excellent modalities are available for correcting high myopia, the surgical treatment of this condition remains one of the biggest challenges for refractive surgeons; this group of patients is often very dependent on contact lenses. If these patients become...

Uveitis‐Glaucoma‐Hyphaemia syndrome retrospective case-control study

The authors present the findings of a case-control study aiming to assess uveitis‐glaucoma‐hyphaemia (UGH) syndrome, focusing on the resolution, glaucoma development and risk factors. The authors compared three groups each containing 71 patients. Each group contained patients with UGH syndrome,...

Risk factors for lens dislocation post cataract surgery

This retrospective cohort study in Korea assessed the risk factors for intraocular lens (IOL) dislocation. They used national data of 2,162,191 patients who had had cataract surgery between 2009 and 2016. They excluded any patient who had an IOL dislocation...
