Anterior Segment Optical Coherence Tomography–Guided Big-Bubble Technique
Purpose:
To evaluate the feasibility of intraoperative anterior segment (AS) optical coherence tomography (OCT) for quantification of the corneal depth reached with the dissecting cannula used for deep anterior lamellar keratoplasty, as well as its correlation with the success rate of big-bubble formation.
Design:
Retrospective, noncomparative, interventional case series.
Participants:
One hundred consecutive keratoconus patients.
Intervention:
Deep anterior lamellar keratoplasty was performed using the big-bubble technique. During surgery, the cannula used for pneumatic dissection was inserted into the peripheral stroma and advanced as deep and far toward the center as (Read more...)
