Intraoperative optical coherence tomography in anterior segment surgeries

Area of Science:

• Ophthalmology
• Surgical Imaging
• Medical Technology

Background:

• Intraoperative optical coherence tomography (iOCT) is a noninvasive imaging technique.
• It offers real-time dynamic feedback during surgical procedures.
• Its utility is increasingly recognized in various ophthalmic surgeries.

Purpose of the Study:

• To review the applications of iOCT in ophthalmic surgery.
• To highlight iOCT's role in decision-making and surgical guidance.
• To discuss current and potential future uses of iOCT.

Main Methods:

• A comprehensive literature search was conducted in MEDLINE.
• Keywords used included "intraoperative optical coherence tomography" and "iOCT."
• The review focused on studies reporting iOCT use in ophthalmic surgeries.

Main Results:

• iOCT aids decision-making in keratoplasty, cataract surgery, and implantable Collamer lens (ICL) implantation.
• It assists in graft assessment, bubble detection, and stromal dissection during keratoplasty.
• iOCT evaluates posterior capsule status, corneal incisions, and ICL vault, and has potential in ocular surface disorder management.

Conclusions:

• iOCT is a valuable tool for real-time guidance and assessment in various ophthalmic surgeries.
• It improves precision in procedures like keratoplasty and cataract surgery.
• Technological advancements are expected to further expand iOCT's capabilities and overcome current limitations.
