Study ObjectiveStudy Objective
To compare safety and vault measurements in
pre-operative Visante OCT images using the
PIOL template with post-operative Visante
OCT images of the same eyes using the
prescribed PIOL.
Ass. Prof. Dr. Camille BUDO
Study MethodsStudy Methods
• Records of patients who had Phakic IOL implantation and had both pre and post-operative Visante scans were reviewed.
• Scans of 56 eyes from 33 patients were qualified for inclusion.
• For each eye, one pre-operative scan had the template placed by the Principal Investigator (CB).
• The following measurements were made for both pre and post-operative eyes:
– Safety measurements at 0 degrees, center and 180 degrees
– Central vault measurements

DiscussionDiscussion
• Safety measurements pre-op are smaller than post-op – conservative approach; template placed higher compared to actual PIOL position
• Vault measurements pre-op are larger than post-op – confirms high placement position of template
• Medium correlation between predicted and actual vault may be due to natural physiological changes of the crystalline lens

CONCLUSIONCONCLUSION
• First experience with the Visante™ OCT phakic IOL simulation tool is promising.
• The results have shown high correlation between predicted clearance of the PIOL to the endothelium and the actual outcome.
• There is a learning curve in placing the template. In this study the templates have been placed higher than the actual implant position.
• The Visante™ OCT software enables the surgeon to optimise the template placement.
