Eye Shape Using Partial Coherence Interferometry, Autorefraction, and SD-OCT

Optical biometry using partial coherence interferometry prior to cataract surgery

Partial coherence interferometry in a teaching hospital.

Partial coherence interferometry (PCI) has an 8% to 22% failure rate for a variety of reasons such as mature cataract, inability to fixate secondary to macular degeneration, tremor, keratopathy, nystagmus, and vitreous hemorrhage. The new composite IOLMaster version 5 software has demonstrated a failure rate of 7.4%, primarily because of posterior subcapsular cataracts. Few studies of the effic...

Optical Coherence Tomography (OCT) of the Anterior Eye Segment

Description of Procedure or Service Optical coherence tomography (OCT) is a high resolution method of imaging the ocular structures. OCT for the anterior eye segment is being evaluated as a non-invasive diagnostic and screening tool for the detection of angle closure glaucoma, to assess corneal thickness and opacity, evaluate pre-surgical and postsurgical anterior chamber anatomy, calculate int...

Simultaneous SD-OCT and Confocal SLO-Imaging

optical coherence tomography (OCT) can be correlated with findings on confocal scanning laser ophthalmoscopy (cSLO) imaging, including fluoresceinand ICGangiography, fundus autofluorescence (FAF) – or reflectance images, in exact topographic correspondance. Simultaneous acquisition is time-efficient and facilitates correlation of findings in the different imaging modalities. Eye tracking allows...
