SMI Surgery Guidance Solution SG3000
SensoMotoric Instruments GmbH (SMI; Berlin) launched the SG3000 surgery-guidance solution for IOLs at the annual meeting of the European Society of Cataract and Refractive Surgeons (ESCRS) in Paris. According to company literature, SMI's surgery-guidance technology allows surgeons to position premium IOLs based on objective data of the eye without using manual markers. Based on a preoperative reference image, the SG3000 provides automated visual guidance for the surgeon by allowing automatic registration and control of the eye position under the surgical microscope. The system guides the surgeon throughout the cataract procedure, including the steps of patient eye confirmation, incisions, capsulorrhexis, multifocal lens centration, and toric lens orientation. It also provides visual guidance with real-time tracking and precise overlays under the microscope.

EyeSuite (Haag-Streit AG, Koeniz, Switzerland) biometry software for the Lenstar LS 900 provides the user with complete biometry of the eye and enables automatic population of the data fields in advanced IOL calculation formulas such as Holladay IOL Consultant (Holladay Consulting, Inc., Bellaire, Texas), PhacoOptics (PhacoOptics, Aarhus, Denmark), or Okulix (Ingenieurbüro der Leu, Hillerse, Germany), according to company literature. With the EyeSuite, biometric data from the Lenstar LS 900 including pachymetry, anatomic anterior chamber depth, and lens thickness can be directly imported into these IOL calculation formula software tools to improve the accuracy of IOL power prediction, specifically in hyperopic, myopic, and post-LASIK eyes. Due to the open architecture of the Lenstar/EyeSuite system, third- party IOL calculation software can be directly installed on the biometer. According to Haag-Streit, this software upgrade is free for all Lenstar LS 900 users. Additionally, script technology introduced with EyeSuite connects the Lenstar optical biometer to electronic medical record systems. Data can be transferred automatically in user-definable text, xml format, or as a PDF to improve workflow.
