PSU9 Time Efficiencies Associated with an Innovative Optical Biometer in Cataract Surgery Planning: A Time-and-Motion Study


      Optical biometers offering higher acquisition rates result in greater success when acquiring axial-length data, which is critical when calculating the intraocular lens (IOL) power, thereby avoiding the use of an ultrasound biometer (manual A-scan), which is invasive and time-consuming. This study aimed to assess efficiencies gained by a swept-source optical-coherence-tomography biometer (ARGOS) through its higher acquisition rate and integration with a digital image guidance system (Verion) compared to a standard biometer (LENSTAR) in cataract evaluation.


      This was an observational time-and-motion study with 22 cataract patients undergoing cataract evaluation and surgery at a single US practice. A within-subjects study to collect time data along with published literature was used to develop a time-efficiency model: Scenario one evaluated time difference between ARGOS and LENSTAR in the presence of Verion and ORA (an intraoperative aberrometer). Scenario two evaluated time difference when ARGOS and Verion were adopted at a practice using LENSTAR (without Verion) and quantified time differences from using digital versus manual marking from Verion. The following time data were collected: time difference between optical biometry measurement for ARGOS versus LENSTAR, Manual A-scan measurement when acquisition failed (4% ARGOS, 21% LENSTAR), additional time from LENSTAR’s inability to digitally integrate with Verion and/or ORA, walking time between instruments, and manual and digital marking time.


      The model demonstrated that for 1,000 patients using Advanced Technology IOL (ATIOL), ARGOS can save up to 74-hours and 25-minutes (4.5 mins/patient) in clinics using Verion and ORA, driven by faster biometry measurement, A-scan avoided from higher acquisition rates and integration capabilities compared to LENSTAR. Adopting ARGOS and Verion exhibited 15-hours and 9-minutes of time savings in clinics using LENSTAR.


      Results from this time-and-motion study demonstrate substantial time efficiencies for healthcare providers and patients in cataract evaluation through ARGOS’ superior acquisition rate and integration capabilities with Verion.
