Your treatment depends on the accuracy of the Diagnosis. We have the best Diagnostic equipment in the industry and skilled health care professionals to calibrate with accuracy and provide excellent results to understand the degree and nature of treatment that the eye surgeon would prescribe. An eye diagnostic is a series of examinations performed by an ophthalmologist (medical doctor), optometrist assessing vision and ability to focus on and discern objects, as well as other tests and examinations pertaining to the eyes. We recommend that all people including children should have periodic and thorough eye examinations as part of routine primary care, especially since many eye diseases are asymptomatic.
Eye examinations may detect potentially treatable blinding eye diseases, ocular manifestations of systemic disease, or signs of tumors or other anomalies of the brain. An eye examination consists of a general external examination, followed by
specific tests as prescribed by our Doctor for visual acuity, pupil function, extraocular muscle motility, visual fields, intraocular pressure and ophthalmoscopy through a dilated pupil.
Keratometer is a fundamental diagnostic instrument to understand the Intra-Ocular Lens (IOL) power which is placed inside your eye lens capsule after the Cataract removal surgery through the measurement of the curvature of the anterior surface
of the cornea particularly for assessing the extent and axis of astigmatism.
A Slit Lamp Examination is a routine Eye exam it helps the Doctor to look at structures in the back of the eye, such as the optic nerve or retina to diagnose problems in the structures in the front of the eye. For example, it can help find problems such as cataracts, conjunctivitis, iritis, or an infection or injury to the cornea. It is also helpful in locating glaucoma or macular degeneration.
Specular microscopy is used to determine the number of cells per square millimeter of the corneal endothelium. Because cataract surgery causes some loss of endothelial cells, the risk of postoperative corneal decompensation is increased if preoperative endothelial cell counts are low. Abnormal endothelial cell morphology, including enlargement (polymegethism) and irregularity (pleomorphism), may limit the cornea’s ability to withstand stress.
Fundus photography involves capturing a photograph of the back of the eye i.e. fundus. Specialized fundus cameras that consist of an intricate microscope attached to a flash-enabled camera are used in fundus photography. The main structures that can be visualized on a fundus photo are the central and peripheral retina, optic disc and macula. Fundus photography can be performed with colored filters, or with specialized dyes including fluorescein and indocyanine green angiography.
Optical Coherence Tomography
Optical coherence tomography (OCT) is an imaging technique that uses coherent light to capture micrometer-resolution, two- and three-dimensional images from within optical scattering media (e.g., biological tissue). It is used for medical imaging and industrial nondestructive testing (NDT). Optical coherence tomography is based on low-coherence interferometry, typically employing near-infrared light. The use of relatively long wavelength light allows it to penetrate into the scattering medium. Confocal microscopy, another optical technique, typically penetrates less deeply into the sample but with higher resolution.
A-scan ultrasound biometry commonly referred to as an A-scan (short for Amplitude scan), is routine type of diagnostic test used in optometry or ophthalmology. The A-scan provides data on the length of the eye, which is a major determinant in common sight disorders. The most common use of the A-scan is to determine eye length for calculation of intraocular lens power. Briefly, the total refractive power of the emmetropic eye is approximately 60. Of this power, the cornea provides roughly 40 diopters and the crystalline lens 20 diopters.
B – Scan Ultrasonography
B-scan ultrasonography helps clinical assessment of various ocular and orbital diseases. With understanding of the indications for ultrasonography and proper examination technique, one can gather a vast amount of information not possible with clinical examination alone. B-scan ultrasonograms of the anterior segment were performed on selected patients. The difficulties in imaging the anterior segment are discussed and the value of this technique is demonstrated by illustration of B-scans in different pathological conditions. This technique can often provide important information and allow an early and accurate prognosis.
