Summary
Intraoperative optical coherence tomography (iOCT) provides real-time imaging for eye surgery. This technology enhances corneal transplantation by guiding surgical decisions for better outcomes and reduced complications.
Area of Science:
- Ophthalmology
- Medical Imaging
- Surgical Technology
Background:
- Intraoperative optical coherence tomography (iOCT) offers near-histologic imaging for ocular surgery.
- Its application in corneal transplantation is particularly promising for guiding surgical decisions.
Purpose of the Study:
- To highlight the applications and benefits of iOCT in various corneal transplantation techniques.
- To discuss the potential of iOCT in improving surgical precision and patient outcomes.
Main Methods:
- Review of iOCT applications in Descemetorhectomy Automated Large Keratoplasty (DALK), endothelial keratoplasty (EK), and penetrating keratoplasty (PK).
- Analysis of how iOCT visualization aids in trephination depth, bubble formation, graft placement, and lamellar apposition.
Main Results:
- iOCT facilitates precise trephination in DALK, leading to better bubble formation and reduced Descemet's membrane perforation risk.
- In EK, iOCT optimizes graft orientation and interface assessment, improving adhesion and reducing re-bubbling.
- iOCT assists in lamellar apposition and centration for mushroom penetrating keratoplasty.
Conclusions:
- iOCT is a valuable tool in corneal transplantation, enhancing surgical accuracy and potentially improving outcomes.
- Ongoing technological advancements in iOCT, such as wider fields of view and autofocusing, promise further integration and utility in ophthalmic surgery.
