Eye Investigation - Dubai Eye Clinic

IOL Calculation (Biometry):

The aim of accurate intraocular lens power calculation is to provide an intraocular lens (IOL) that fits the specific needs and desires of each patient

The development of better instrumentation for measuring the axial length of the eye and the usage of precise mathematical formulas to perform the appropriate calculations have significantly improved the accuracy with which our surgeons determine the intraocular lens power.

In order to determine the power of IOL we measure the following factors:

• The eye’s axial length
• Corneal power (K readings)
• Anterior chamber depth
• Lens thickness
• Corneal topography

Corneal Topography:

Corneal topography is a non-invasive medical imaging technique for mapping the surface curvature of the cornea (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

It is very important to be done for diagnosis and follow-up of some corneal diseases such as keratoconus, and before refractive surgery.

Optical Coherence Tomography (OCT):

Optical coherence tomography (OCT) is a non-invasive imaging test. OCT uses light waves to take cross-section pictures of your retina (macula) and optic disc.

With OCT, your ophthalmologist can see each of the retina’s distinctive layers. This allows your ophthalmologist to map and measure their thickness. These measurements help with the diagnosis of retinal diseases including age-related macular degeneration (AMD) and diabetic eye disease. They also provide treatment guidance for glaucoma and optic nerve diseases.

Anterior segment OCT(AOCT):

It is a minimally invasive painless test with no contact with the eye. It detects very subtle morphological changes to the eye structures, providing extremely valuable information beyond examinations using a slit lamp.
This test provides an objective assessment of aspects such as the thickness of the cornea in patients with keratoconus or candidates for refractive surgery, the dimensions of the anterior chamber for intraocular lens implantation, or the iridocorneal angle (forming the cornea with the iris) in cases of closed-angle glaucoma.

Optical Coherence Tomography Angiography (OCTA):

It is an imaging modality that can be applied to provide a detailed perfusion view of the vascular network of the eye.
Compared to fluorescein angiography, OCTA is non-invasive and time-efficient. Moreover, it allows full examination of retinal vasculature in 3D

Visual Field Test:

A visual field test can determine if you have blind spots (called scotoma) in your vision and where they are. A scotoma’s size and shape can show how eye disease or a brain disorder is affecting your vision.

Visual field testing is an important part of regular eye care for people who are at risk of vision loss from disease and other problems.

People with the following conditions should be monitored regularly by their ophthalmologist, who will determine how often visual field testing is needed:

• Glaucoma
• Multiple sclerosis
• Thyroid eye disease
• Pituitary gland disorders
• Central nervous system problems (such as a tumor that may be pressing on visual parts of the brain)
• Stroke
• Long-term use of certain medications (such as Plaquenil, or hydroxychloroquine, which requires yearly visual field checkups)

People with diabetes and hypertension have a greater risk of developing blocked blood vessels in the optic nerve and retina. They may need visual field testing to monitor any effects of these conditions on their vision.
