  1. Visante OCT PIOL simultation study C. BUDO, Ass Prof MD University Clinic of Maastricht Ophthalmology, Site Sint-Truiden camille.budo@skynet.be Medical Mentor OPHTEC BV Consultant OPHTEC BV Consultant CARL ZEISS Ass. Prof. Dr. Camille BUDO

  2. Study 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

  3. Study 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 Ass. Prof. Dr. Camille BUDO

  4. Implantation simulation Ass. Prof. Dr. Camille BUDO

  5. Discussion • 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 Ass. Prof. Dr. Camille BUDO

  6. CONCLUSION • 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. Ass. Prof. Dr. Camille BUDO
