First, second, and third prizes for the best cataract and refractive posters were awarded on Sunday afternoon during the Video Awards Session.  The posters are judged based on originality, scientific quality, relevance to clinical practice and presentation.


First prize in the refractive category was given to Emilio Torres-Netto MD, Switzerland, for his poster “Stromal bed smoothness after excimer laser surface ablation as a key element for the expression of inflammatory genes”.

The poster presented findings from a study conducted in animal eyes that identified expression of inflammatory genes following PRK performed with a standard versus low fluence ablation. Ablations were done using technology based on a three-dimensional fullerene model to smooth the stromal bed.

The results showed that the optimisation of new algorithms or energy settings allowed for reduction of the inflammatory response after refractive laser surgery. In addition, Dr Torres-Netto concluded that postoperative corneal smoothness appears to be the key factor in regulating the inflammatory response.

Yuka Horigome MD, Japan, received the second prize for refractive posters for his presentation of a “Novel technique of intrascleral IOL fixation with intraoperative adjustment of refraction”.

Third prize went to Zhou Jihong, MD, China, for the poster “Clinical outcomes of a large sample after small-incision lenticule extraction and femtosecond laser-assisted in situ keratomileusis for myopia by generalised linear mixed models (GLMM) analysis”.


First prize for cataract posters was awarded to Daniel Chang MD, USA, for his poster “Visual outcomes and defocus curve profile of a next-generation diffractive presbyopia-correcting intraocular lens”.

The poster presented defocus curve and visual acuity outcomes from a multi-centre randomised study that included 148 patients bilaterally implanted with the TECNIS Synergy IOL or the +3.25D TECNIS Multifocal IOL. The surgeries were performed at 12 centres across the United States.

The study found that the TECNIS Synergy IOL maintained excellent continuous vision up to 33cm with distance vision better than 1.0 (20/20). Compared with the multifocal IOL, the TECNIS Synergy provided both better DCIVA and had a better range of vision.

Second prize for cataract posters went to Grzegorz Labuz, MD, Germany, for his poster describing “Laboratory assessment of the effect of spectral filters on the optical performance in an extended-depth-of-focus intraocular lens”.

Arthur Cummings, Ireland, received the third prize for his work addressing the question “Does an objective evaluation of patients’ daily life influence surgeon selection of presbyopia-correcting IOLs?”
