The Innovation in Retina Research Award is being offered by the Canadian Ophthalmological Society (COS) with the support of Bayer Inc. for clinical trainees (residents or fellows) for a research project proposal related to retinal disease, with preference being given to research that has the potential to advance knowledge about or improve the care of patients. To determine final standing, the top three selected submissions will present their research proposal during this virtual symposium and respond to questioning by our judging Lions.  The symposium audience will also be able to vote for its choice of the top pitch.

CANMEDS Roles: Medical expert, Scholar

This symposium was co-developed by the Canadian Ophthalmological Society and Bayer Inc. and was planned to achieve scientific integrity, objectivity and balance.

AstigMATIC is a free standalone application for automated standardized astigmatism vector analyses in corneal and intraocular refractive surgeries. AstigMATIC allows the simultaneous display and analysis of astigmatism magnitude and axis.

The software produces the four following graphs according to current journal standards: 1-Target-Induced Astigmatism Vector, 2-Surgically-Induced Astigmatism Vector, 3-Difference Vector and 4-Correction Index. Vector means with standard deviations are automatically calculated and displayed on the corresponding single-angle vector plots (0 to 180°). The standard graphs can be easily exported as high-resolution TIFF images for figures to use in production and presentations.

The software can be downloaded at:
https://www.lasikmd.com/media/astigmatic/index.php.

The software was thoroughly tested, peer-reviewed and published in BMC Ophthalmology, the paper about the software is available at: https://bmcophthalmol.biomedcentral.com/articles/10.1186/s12886-018-0920-1

mEYEstro is a user-friendly software that automatically generates standardized graphs for refractive surgery outcomes – as prescribed by JRS, JCRS, and Cornea Journals.

The software produces the following 11 standard graphs; Efficacy: 1. Cumulative uncorrected (UDVA) and corrected visual acuity (CDVA), 2. Difference between UDVA and CDVA, Safety: 3. Change in line of CDVA, Accuracy: 4. Spherical equivalent (SEQ) to intended target, 5. Attempted vs. achieved SEQ, 6. Defocus equivalent (DEQ) accuracy, 7. Refractive astigmatism accuracy, 8. Target-induced astigmatism vs. Surgically-induced astigmatism, 9. Correction index histogram, 10. Angle of error histogram, Stability: 11. SEQ stability over time. Percent proportions, means, standard deviations, Cohen’s d effect sizes, and p-values are calculated and displayed on each graph. All graphs can be easily exported as high-resolution TIFF images for figures to use in scientific manuscripts and presentations.

The software can be downloaded at https://www.lasikmd.com/media/meyestro/index.php, and a tutorial is available at https://www.youtube.com/watch?v=NFlRRHx6ZaI.
