LABARATORY


A supportive service at Lions Eye Hospital, this department provides the necessary laboratory investigations required for patient care to ensure physical health status before eye surgery. The Laboratory dedicates its self to providing comprehensive and high-quality laboratory services to the communities, physicians and patients. The services include:

  • Blood Sugars
  • Blood Pressure
  • Full Haemogram Testing
  • Lipid Profile Test
  • Kidney Function Tests
  • Liver Function Tests
  • Thyroid Function Tests
  • STIs Tests – HIV Testing and Counseling
  • Vitamin B12 & Vitamin D3 Tests
  • Hepatitis Screening Tests
  • H. Pylori Test
  • Uric Acid for Arthritis

OCCULAR


A Scan Ultrasound Biometry

Commonly known as A-scan. It 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.

B Scan Ocular Ultrasound

Is a simple, non-invasive tool for diagnosing lesions of the posterior segment of the eyeball. Common conditions such as cataract, vitreous degeneration and retinoblastoma can be accurately evaluated with this modality.

Auto Refraction

A computer-controlled measurement used during an eye examination to provide an objective measurement of a person's refractive error and prescription for glasses or contact lenses.

Keratometry

Also known as ophthalmometry, this is a diagnostic technique used to measure the curvature of the anterior surface of the cornea, particularly for assessing the extent and axis of astigmatism.

Pachymetry

Measuring the thickness of the cornea using a pachymeter prior to refractive surgery, for keratoconus screening, LRI surgery.

Ocular Coherence Tomography (OCT)

A non-invasive imaging test that uses light waves to take cross-section pictures of your retina, the light-sensitive tissue lining the back of the eye.

Tonometry

This 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.

Visual Field Test

Is an eye examination that can detect dysfunction in central and peripheral vision which may be caused by various medical conditions such as glaucoma, stroke, brain tumors or other neurological deficits.

Ocular Topography

Also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye. Since the cornea is normally responsible for some 70% of the eye's refractive power, its topography is of critical importance in determining the quality of vision and corneal health.

Angiography

Flourescein angiography is a technique for examining the circulation of the retina and choroid using a fluorescent dye and a specialized camera. It involves injection of sodium fluorescein into the systemic circulation, an angiogram is then obtained by photographing the fluorescence emitted after illumination of the retina with blue light at a wavelength of 490 nanometers.
