Binocular testing with an adaptive optics-based vision simulator can accurately predict patients’ visual performance under binocular conditions with different monofocal and multifocal intraocular lens (IOL) designs, according to a study presented by Pablo Artal PhD at the XXXII Congress of the ESCRS in London.

The excimer laser has been the reliable workhorse of corneal refractive surgery practices for the past two decades, providing excellent visual outcomes and a high degree of safety for millions of satisfied patients worldwide.

Performing a glued intraocular lens (IOL) is a challenge in patients who have either larger or smaller than normal eyes. The challenge in large eyes is to get a sufficient degree of haptic exteriorised, resulting in insufficient haptic tuck and a potentially unstable IOL.

Abbott Medical Optics think their new Tecnis Symfony intraocular lens (IOL), approved for use in Europe, can do what multifocal IOLs have not – convince more cataract patients to try presbyopia-correcting lenses.


In the six years since the dawn of femtosecond laser-assisted cataract surgery (FLACS), precise capsulotomies have been touted as one of its biggest advantages. Perfectly sized, shaped and centred anterior capsule openings should help position and stabilise intraocular lenses (IOLs), leading to more predictable effective lens position and better visual outcomes, proponents say.

Intraoperative wavefront aberrometry measurements of refraction in the aphakic stage of a cataract procedure show good reproducibility, but good measurements are only possible in about half of attempts and the range of error appears to be too large to be used in a clinical setting, according to the results of a study presented by Jan O Huelle MD at the XXXII Congress of the ESCRS in London.

Secondary intraocular lens (IOL) procedures with modern surgical techniques can provide visual improvements in most patients, although ocular comorbidities double the risk of a poor visual outcome, suggests a long-term retrospective study.
