Topcon Triton Swept Source OCT Angiography

We are proud to introduce for the first time swept source OCT angio machine outside institutional setup in the city of Hyderabad and the states of Telangana and AP. It detects motion contrast and identifies blood flow in vessels by detecting difference in signals in multiple successive scans.

Scan rates have increased from 7000 A scans per second in time domain OCT to about 1,00,000 A scans per second in the current generation of Swept source OCT thereby providing higher resolution of OCT.

Advantage of SSOCTA over FFA:

  • Non invasive
  • Quick
  • No need for fasting before procedure
  • No need to monitor for nausea or allergic reaction after the procedure

Advantage of SS OCTA over Spectral domain OCT (SD OCT):
SS OCT works at a wavelength of 1050 nm while SD OCT works at a wavelength of 840 nm. Due to higher wavelength, SS OCT can

  • Image better even through media opacity like cataract
  • Image deeper into choroid with minimal loss of strength providing better choroidal visualisation

It is comprehensive too.
SSOCTA report provides comprehensive picture showing angiography report of different layers (Superficial capillary network, deep capillary network, outer retina and capillary network of choroid), a high quality SS OCT image and a fundus image. This helps in comparing the various aspects of the OCT simultaneously thereby making better interpretations

This machine can also be used to image anterior segment as well as in glaucoma for measurements of angles and disc angiogram and nerve fibre layer analysis


Zeiss Visucam 524

We are equipped with the latest generation Carl Zeiss Visucam 524 machine which has a simple design and is easy to handle and provides ultra high resolution(24 megapixels) fundus imaging in multiple modalities including FFA, ICG and fundus autofluorescence.


Marvel B scan with Ultrasound Biomicroscopy (UBM)

We are equipped with both Ultrasound B scan and UBM. B scan helps in imaging the posterior segment of the eye while UBM helps to image the pars plana, ciliary body and the anterior chamber of the eye. This helps in identifying both posterior segment disorders as well as anterior segment pathologies.

    B-scan:
  • Posterior segment pathologies through opaque media
  • Lens dislocation
  • Retinal detachment
  • Tumours

  • UBM:
  • Anterior chamber angle analysis
  • Ciliary body pathology
  • Integrity of posterior capsule of lens
  • Position of IOL implant
  • Management of uveitis/scleritis

Zeiss Humphrey Field Analyzer 3

The new Zeiss HFA3 comes with the latest Liquid Lens Technology which enables faster examination by automatically loading the patient’s refractive correction from their previous exam. This also reduces chance of error when selecting a lens during test setup.
It has an improved gaze tracking initialization and easy to use kinetic graphical user interface with full 180° testing range.

It measures progression simply and easily with Guided Progression Analysis (GPA). RelEYE helps to preserve an image of the patient’s eye at every stimulus presentation during a SITA Standard test.

It checks for ptosis or trial lens rim artifacts as well as assess patient's compliance with RelEYE in both GPA and single-field analysis modes.


Nidek AL Scan

  • 3D auto-tracking and auto-shot
  • Measures axial length, anterior chamber depth, white to white diameter, corneal curvature radius, central corneal thickness, pupil size
  • Scheimpflug camera for anterior segment imaging
  • Sectional lens image for density of cataract
  • Mire rings for irregular corneal surface
  • Multiple IOL power calculation formulae
  • Suitable for dense cataracts and silicon oil filled eyes as well

NIDEK Multispot & multi wavelength (Green and yellow) LASER:

Envision has one of the most advanced LASER delivery system for posterior segment disorders. The LASER delivery system has multiple wavelengths thereby catering to varying indications. While green LASER is traditionally the first choice of treatment, yellow LASER has some inherent advantages like

  • Less energy scatter in hazy media like cataract thereby ensuring better tissue reach
  • Better treatment of retinal vascular structures
  • Less absorption by foveal xanthophylls, thereby enabling better management of foveal pathologies

Similarly, the advantages of multisport LASER over the conventional single spot LASER include

  • It causes less pain
  • It is quicker
  • It results in lesser macular oedema due to lesser energy used

The entire 3 sittings of PRP can be concluded in a single session if required in certain deserving situations


VISULAS YAG III laser from Zeiss:

We are equipped with the best YAG delivery system and is suitable for indications like YAG capsulotomy and YAG iridotomy. It ensures optimum amount of energy being delivered to the target tissue resulting in minimal amount of energy being needed for photodisruption and high precision treatment.
