The various investigations we offer at our hospital
mage Guided System is designed to offer improved precision, consistency and control in cataract refractive surgery.It ensures better post surgical outcome by enabling precise pre operative workup which helps in deciding placement of incisions during surgery. Post operative glass prescription is minimized as a result.
The VERION™ Image Guided System Can help:
- Minimize data transcription errors
- Improve clinical efficiency
- Increase toric and multifocal IOL confidence
- Ensure surgical consistency
- Optimize visual outcomes
It allows fast, accurate measurements of eye length and surface curvature, necessary for cataract surgery.It helps in reducing refractive error post operatively by appropriate selection of lens. Calibrated against the ultra-high resolution 40-MHz Grieshaber Biometric System, an internal algorithm approximates the distance to the vitreoretinal interface, for the equivalent of an immersion A-scan ultrasonic axial length.
It is a diagnostic test used in ophthalmology to produce a two-dimensional, cross-sectional view of the eye and the orbit. It is otherwise called brightness scan. it is commonly used to see inside the eye when media is hazy due to cataract or any corneal opacity is there
4) Optical coherence tomography (OCT)
It is an established medical imaging technique that uses light to capture micrometer-resolution, three-dimensional images from within optical scattering media (e.g., biological tissue). it can be used to obtain detailed images from within the retina. This investigation is used to detect swelling in central part of retina called macula which is responsible for central vision. It is used to decide line of management for macular edema(swelling) .
5) Fundus photography
It 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. These tests can be used to detect and monitor progression of diabetic retinopathy and response to treatment.
H V Desai eye hospital is one of the first institutes in Pune to have pentacam. Itimages the anterior segment of the eye by a rotating Scheimpflug camera measurement. This rotating process supplies pictures in three dimensions. The center of the cornea is measured very precisely because of this rotational imaging process. The Pentacam provides 3-dimensional chamber analysis of the complete anterior segment of the eye, measurement of curvature of both the front and the back of the cornea, thickness measurements across the entire diameter of cornea. It also can provide cataract analysis and clearly detect corneal disorders such as Keratoconus, where laser vision correction is sometimes not appropriate.
It is the procedure eye care professionals perform to determine the intraocular pressure (IOP), the fluid pressure inside the eye. It is an important test in the evaluation of patients at risk from glaucoma.At our institute we offer non contact tonometry as well as applanation tonometry.
8) Automated refractor
It is a computer-controlled machine used during an eye examination to provide an objective measurement of a person's refractive error and prescription for glasses or contact lenses.
9) keratometry and ascan
- They are used to calculate corneal curvature and axial length respectively and intraocular lens power calculation before cataract surgery.
-It is a visual field test that can detect dysfunction in central and peripheral vision which may be caused by various medical conditions such as glaucoma, stroke, pituitary disease, brain tumours or other neurological deficits.
It is an instrument used to capture retinal images. In our institute we use it to screen preterm or term infants who were on oxygen therapy in their early neonatal period, for retinopathy of prematurity. Retinopathy of prematurity (ROP) is a disease that occurs in premature babies. It causes abnormal blood vessels to grow in the retina, the layer of nerve tissue in the eye that enables us to see. This growth can cause the retina to detach from the back of the eye, leading to blindness. By early detection by using this device we can prevent potential blindness in infants by early intervention and treatment.
We do blood investigations like Hemogram, serology for HIV, HCV, HbsAg, gram stain for bacteria, KOH stain for fungal infections, blood culture and tissue culture for microbial pathogen detection.
