Optical Coherence Tomography, or OCT, is a non-invasive diagnostic technique that gives cross-sectional view of the retinal layers. It is useful in the diagnosis of many retinal diseases especially when the media is clear.
A-Scan / Biometry provide data on the length of eye. The most common use of A-Scan is to determine eye length for calculation of Intra-Ocular lens power, even in the presence of opacity / cataract.
A visual field test is an eye examination that can detect dysfunction in central and peripheral vision. Assessment of these functions may be missed on routine eye checkup. Assessment of these functions is especially important in diseases where central vision may remain normal till advance stages. In this test, visual field testing is performed by keeping the subject’s gaze fixed while presenting objects at various places within their visual field.
Fundus Flourescein Angiography (FFA) is the creation of a photograph of the interior surface of the eye including the retina, optic disk, macula and posterior pole i.e. the fundus. It is used by ophthalmologists for monitoring progression and diagnosis of the disease.
HRT is a diagnostic procedure used for precise observation of the optic nerve head essential for the diagnosis of glaucoma.
Pachymetry is the process of measuring the thickness of the cornea. The instrument used is called pachymeter. Corneal thickness indicates the health of the cornea. It is usually done prior to refractive surgery, collagen cross linkage and management of glaucoma.
Corneal topography provides colour coded map of the corneal surface. The colours and powers show us the corneal shape before and after refractive surgery, corneal grafting or cataract extraction.
Specular microscopy helps to visualize and analyze the corneal endothelium. It tells about the number, size and shape of endothelial cells. It helps in diagnosis of different pathologies which can affect eye especially post operatively.
Corneal confocal microscopy is a non-invasive technique to study corneal cellular structure as well as all the layers of cornea. It has been used in the detection and management of corneal pathologies like infections, dystrophies, ectasias and pre and post evaluation of corneal surgeries.
Galilei is a high precision optical system for corneal topography and 3D (three dimensional) analysis of the anterior eye segment. Galilei helps to determine the suitability of eyes for corrective surgery.
RetCam is used by ophthalmologists for capturing photographs of fundus. These pictures are used for diagnosis of the diseases of retina, especially in children and infants as it is done in a non-stressful manner.
IOL Master is the based on the most modern technology. Unlike traditional A-Scan / Biometry, it is a non-invasive method for calculation of IOL (intra-ocular lens) for cataract patients.
