Clinical Experience With the First Commercially Available Intraoperative Optical Coherence Tomography System

Area of Science:

• Ophthalmology
• Surgical Technology
• Medical Imaging

Background:

• The first commercial intraoperative optical coherence tomography (iOCT) system was evaluated.
• This retrospective case-series assessed initial clinical experiences with iOCT.

Purpose of the Study:

• To evaluate the initial clinical experience with a novel intraoperative optical coherence tomography (iOCT) system.
• To determine if iOCT imaging provides additional information and alters decision-making in ophthalmic surgery.

Main Methods:

• A retrospective, single-center case-series of 40 consecutive cases utilizing the Rescan 700 iOCT system.
• Standardized review to assess iOCT's impact on information gain and surgical decision-making.

Main Results:

• iOCT imaging provided additional information in 74.1% of posterior/combined surgeries, altering decisions in 41.9%.
• Anterior segment procedures showed information gain in 22.2% with no altered decisions.
• Average iOCT imaging times were 167 seconds (posterior) and 117 seconds (anterior).

Conclusions:

• Intraoperative optical coherence tomography (iOCT) shows potential to enhance both posterior and anterior segment ophthalmic surgeries.
• The system is compatible with common surgical adjuncts like chromovitrectomy dyes and tamponades.
