The winning videos in the 2018 Video Competition highlighted innovative independent research offering potential solutions to many of the unresolved issues in cataract and refractive surgery.
The overall winner for this year’s video competition was Jiri Cendelin, Czech Republic, for “Iris reconstructive surgery”. The presentation described the design of a large model of the anterior eye for strategising and practising iris surgery. Ten times larger than a typical human eye, the model can be used to practise a range of surgical manoeuvres, including incisions and suture techniques, using similarly scaled tools. The model also includes scale models of capsular tension rings and aniridic IOLs for placement in the sulcus and capsule.

DIFFICULT AND SPECIAL CASES
Athiya Agarwal, India, took first prize in the Difficult and Special Cases category for “Contiguous corneal delamination for giant OSSN”. She presents a case-study in which she performed a corneal-surface-preserving technique for excising a giant ocular surface squamous neoplasia (OSSN). The neoplastic lesion measured approximately 20mm x 18mm and wrapped the entire 12 clock hours of the cornea. Postoperatively, there were no sequelae and at the most recent evaluation the eye had a clear cornea without a residual scar and a best-corrected visual acuity of 20/20.

EDUCATIONAL
First prize in the Educational category went to Graham Barrett, Australia, for “Plotting the right course for toric IOLs”. In it he presents his research showing that IOL calculations based on keratometry readings using the LenStar biometer would result in a higher proportion of eyes within 0.5D of emmetropia than IOL calculations using the IOLMaster 500 or the Pentacam, the greatest number achieving that refraction could be obtained using a calculation using K values 
obtained by all three machines. He also describes how he has integrated that potential functionality into the online Barrett Toric IOL Calculator.

HISTORICAL
The winning video in the Historical category was Masara Laginaf, UK, for “The secret society of the oculists: enlightened pioneers or covert freemasons?” Dr Laginaf presents an analysis of the only recently decoded manifesto of the 18th-Century secret Highly enlightened society of oculists. The Cipher depicts the society’s arcane initiation ceremony and contrasts its members to inferior surgeons performing ocular surgery at the time. It also describes masonic rituals in great detail, suggesting a secondary motivation for the book.

INNOVATIVE

In the Innovative category, Ritika Dalal, India, took first prize for “Sailing through post photorefractive keratectomy pain”, which showed how the use of a preservative-free ketorolac-soaked bandage contact lens can reduce the early post-operative Wong-Baker pain scale from 8 to 2 in patients after undergoing the surface ablation procedure.

SCIENTIFIC CATEGORY

Gerd Uwe Auffarth, Germany, took first prize in the Scientific category for “CSI Heidelberg: focusing on multifocal and EDOF technology”. The video presents a comparison of the peaks and ranges in focal power of three multifocal lenses and four extended depth of field lenses, using a green laser shone first through the lens and then through water stained with a fluorescent buffer to visualise the optical pathways.

RESIDENT IN TRAINING

First prize in the Resident in Training category went to Akshay Kothari, India, for “Hunting the Great Whites”. The video outlines the modifications necessary in the phacoemulsification of intumescent cortically mature cataracts with a hard brown nucleus and soft cataracts with a gelatinous cortex, and how to deal with common problems of shallow anterior chambers, fragile capsules and weak zonules.
