Evaluation of intraoperative aphakic eye axial length measurements using swept-source OCT.

Purpose: To evaluate intraoperative aphakic eye axial length (AL) measurements using swept-source optical coherence tomography (SS-OCT).

Setting: Hanusch Hospital, Vienna, Austria.

Design: Prospective single-center study.

Intraoperative optical coherence tomography measurements of aphakic eyes to predict postoperative position of 2 intraocular lens designs.

Purpose: To evaluate intraoperative anterior chamber depth (ACD) measurements of the aphakic eye to predict the postoperative ACD and compare 2 intraocular lens (IOL) designs.

Setting: Hanusch Hospital, Vienna, Austria.

Design: Prospective study.

Using continuous intraoperative optical coherence tomography to classify swirling lens fragments during cataract surgery and to predict their impact on corneal endothelial cell damage.

Purpose: To quantify and classify swirling lens fragments during cataract surgery and record their impact on the corneal endothelium using continuous intraoperative optical coherence tomography (OCT).

Setting: Vienna Institute for Ocular Surgery, Hanusch Hospital, Vienna, Austria.

Design: Prospective case series.

Using continuous intraoperative optical coherence tomography measurements of the aphakic eye for intraocular lens power calculation.

Background/aims: To include intraoperative measurements of the anterior lens capsule of the aphakic eye into the intraocular lens power calculation (IPC) process and to compare the refractive outcome with conventional IPC formulae.

Methods: In this prospective study, a prototype operating microscope with an integrated continuous optical coherence tomography (OCT) device (Visante attached to OPMI VISU 200, Carl Zeiss Meditec AG, Germany) was used to measure the anterior lens capsule position after implanting a capsular tension ring (CTR). Optical biometry (intraocular lens (IOL) Master 500) and ACMaster measurements (Carl Zeiss Meditec AG, Germany) were performed before surgery.

Predicting the postoperative intraocular lens position using continuous intraoperative optical coherence tomography measurements.

Purpose: The aim of this study was to assess, if measuring the position of the lens capsule intraoperatively with a continuous intraoperative optical coherence tomography (OCT) device could be useful to improve the prediction of the intraocular lens (IOL) position.

Methods: This prospective study included patients who were scheduled for cataract surgery. A prototype operating microscope with an integrated continuous OCT device was used to measure the anterior and posterior lens capsule position at different time points during cataract surgery.
