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.
