Optical coherence tomography (OCT) is an established technique that uses light to capture micrometre-resolution, three-dimensional images from within optical scattering media (e.g., biological tissue). It is a non-invasive imaging technique that provides high-resolution, cross-sectional images of the retina, retinal nerve fiber layer and the optic nerve head. This review discusses the diagnosis and management of retinal diseases, with particular emphasis on choroidal imaging.

YAG (neodymium-doped yttrium aluminium garnet; Nd:Y3Al5O12) lasers is a crystal that is used as a lasing medium for solid-state lasers. The dopant, triply ionized neodymium, Nd(III), typically replaces a small fraction (1%) of the yttrium ions in the host crystal structure of the yttrium aluminium garnet (YAG), since the two ions are of similar size. It is the neodymium ion which provides the lasing activity in the crystal, in the same fashion as red chromium ion in ruby lasers.They are most commonly used to treat posterior capsular opacification after cataract surgery and to create a peripheral iridotomy in patients with narrow angles or angle-closure glaucoma.
The slit lamp is an instrument consisting of a high-intensity light source that can be focused to shine a thin sheet of light into the eye. It is used in conjunction with a biomicroscope. The slit lamp exam usually forms part of a comprehensive eye exam.
A pachymeter is a medical device used to measure the thickness of the eye’s cornea. It is used to perform corneal pachymetry prior to refractive surgery, for Keratoconus screening, LRI surgery and is useful in screening for patients suspected of developing glaucoma among other uses.
The Humphrey Visual Field Analyser (HVFA), is a tool for measuring the human visual field, it is used by optometrists, orthoptists and ophthalmologists, particularly for detecting monocular visual field.It provides information regarding the location of any disease processes or lesion throughout the visual pathway. This guides and contributes to the diagnosis of the condition affecting the patient's vision. These results are stored and used for monitoring the progression of vision loss and the patient's condition.
Corneal topography is a computer assisted diagnostic tool that creates a three-dimensional map of the surface curvature of the cornea. The cornea (the front window of the eye) is responsible for about 70 percent of the eye’s focusing power. An eye with normal vision has an evenly rounded cornea, but if the cornea is too flat, too steep, or unevenly curved, less than perfect vision results. The greatest advantage of corneal topography is its ability to detect irregular conditions invisible to most conventional testing. Corneal topography produces a detailed, visual description of the shape and power of the cornea. This type of analysis provides your doctor with very fine details regarding the condition of the corneal surface. These details are used to diagnose, monitor, and treat various eye conditions. They are also used in fitting contact lenses and for planning surgery, including laser vision correction. For laser vision correction the corneal topography map is used in conjunction with other tests to determine exactly how much corneal tissue will be removed to correct vision and with what ablation pattern.
TMicrosurgery is a general term for surgery requiring an operating microscope. Microsurgical techniques are utilized by several specialties today, such as: general surgery, ophthalmology, orthopedicsurgery, gynecologicalsurgery, otolaryngology,neurosurgery, oral and maxillofacial surgery, plastic surgery, podiatric surgery andpediatric surgery etc
Retinal Photocoagulation Lasers are used to treat a variety of eye diseases including the two leading causes of blindness: Diabetic Retinopathy and Age-related Macular Degeneration. This precision laser can lower the risk of vision loss by cauterizing ocular blood vessels. Two types of Photocoagulation Lasers are used – the first is Focal Photocoagulation, which treats specific leaking blood vessels in the retina. The second is Scatter or Pan-retinal Photocoagulation; – used for more widespread damage over the retina. The risk of using a Retinal Photocoagulation Laser is low and side effects are rarely severe.
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 flashed 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.
Optical coherence tomography angiography (OCTA) is a new, non-invasive imaging technique that generates volumetric angiography images in a matter of seconds. This is a nascent technology with a potential wide applicability for retinal vascular disease.
Phacoemulsification is a modern cataract surgery in which the eye’s internal lens is emulsified with an ultrasonic hand piece and aspirated from the eye. Aspirated fluids are replaced with irrigation of balanced salt solution, thus maintaining the anterior chamber, as well as cooling the hand piece.
An exclusive optical shop with many reputed brands for frames, contact lenses, etc within the hospital. It offers a range of sunglasses, fancy frames for children and adults. A complete quality check is performed by well experienced staff on all the products to ensure compliance to the standards.
contact lenses are medical devices placed on the eyes, they require expert fitting and careful instruction, as well as conscientious care and compliance with recommended follow-up examinations to maintain the healthy functioning of your eyes. Contact lenses not only enhance visual acuity and appearance, but also improve performance in different visual tasks; helps avoid fogging of glasses in different environments, and also improve performance of other fast activities like sports.
The Clinic aims to provide the best possible management for persons with low vision. People who are unable to see objects (say a person’s face) beyond maximum of 3m i.e., 10 feet distance (with their spectacle correction) and / or people those who have side vision difficulty are said to have low vision. When ordinary eye glasses, contact lenses or intraocular lens implants cannot provide sharp sight, an individual is said to have low vision. Although reduced central or reading vision is common, low vision may also result from decreased side (peripheral) vision, a reduction or loss of clarity of vision, or the eye's inability to properly adjust to light or glare. The Clinic helps in enhancing the existing potential vision of the patients
Ocular prosthesis is an artificial eye, which is implanted in patients who have lost their eye due to various causes such as trauma, surgery, cancer, or in patients with shrunken damaged eyes (phthisical eyes), congenital absence (anophthalmos) or abnormally small sized eyes (microphthalmos) with no visual potential. Cosmetic rehabilitation for these patients through the implantation of ocular prosthesis helps in restoring the patients’ confidence by improving their external appearance. The Ocular prostheses are fitted behind the eyelids over a shrunken eyeball or an orbital implant placed following surgical removal of the eye.
