At Eye Consultants Center, we employ cutting-edge technology to conduct a comprehensive array of investigations to ensure the utmost precision and accuracy in our diagnoses and treatments.
Our commitment to excellence is exemplified by our use of state-of-the-art equipment, which enables us to perform a wide range of diagnostic procedures.
The aim of an accurate intraocular lens power calculation is to provide an intraocular lens (IOL) that fits the specific needs and desires of the individual patient. The development of better instrumentation for measuring the eye’s axial length (AL) and the use of more precise mathematical formulas to perform the appropriate calculations have significantly improved the accuracy with which the surgeon determines the IOL power.
In order to determine the power of intraocular lens several values need to be known:
Of these parameters the first two are measured before the implantation, the third parameter, the ELP, need to be estimated mathematically before the implantation and the last parameter is provided by the manufacturer of the intraocular lens.
Optical coherence tomography (OCT) is a non-invasive imaging test. OCT uses light waves to take cross-section pictures of your retina.
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 diagnosis. They also provide treatment guidance for glaucoma and diseases of the retina. These retinal diseases include age-related macular degeneration (AMD) and diabetic eye disease.
Optical coherence tomography angiography (OCTA) is an imaging modality which can be applied in ophthalmology to provide detailed visualization of the perfusion of vascular networks in the eye. Compared to previous state of the art dye-based imaging, such as fluorescein angiography, OCTA is non-invasive, time-efficient, and it allows for the examination of retinal vasculature in 3D
(FA) is a diagnostic procedure that uses a special camera to record the blood flow in the RETINA – the light sensitive tissue at the back of the eye.
The test does not involve any direct contact with the eyes. Your eyes will be dilated before the procedure.
Fluorescein dye is injected into a vein in the arm/hand. As dye passes through the blood vessels of your eye, photographs are taken to record the blood flow in your retina. The photographs can reveal abnormal blood vessels or damage to the lining underneath the retina.
Color Fundus Retinal Photography uses a fundus camera to record color images of the condition of the interior surface of the eye, in order to document the presence of disorders and monitor their change over time.
A fundus camera or retinal camera is a specialized low power microscope with an attached camera designed to photograph the interior surface of the eye, including the retina, retinal vasculature, optic disc, macula, and posterior pole (i.e. the fundus).
The retina is imaged to document conditions such as diabetic retinopathy, age related macular degeneration, macular edema and retinal detachment.
Fundus photography is also used to help interpret fluorescein angiography as certain retinal landmarks visible in fundus photography are not visible on a fluorescein angiogram.
Your eyes will be dilated before the procedure. Widening (dilating) a patients pupil increases the angle of observation. This allows the technicians to image a much greater area and have a clearer view of the back of the eye.
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 for 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), and Stroke.
Long-term use of certain medications (such as Plaquenil, or hydroxychloroquine, which requires yearly visual field checkups)
People with diabetes and high blood pressure 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.
If your visual field is limited, your ability to drive may be in jeopardy. If you are concerned about vision loss or your ability to continue driving, talk with your ophthalmologist.
What is an A-Scan?
An A-scan is short for amplitude scan. It is a type of ultrasound biometry that is provides data on the eye’s length. Determining eye length is crucial regarding many common sight disorders, including near-sightedness and far-sightedness. However, for these common conditions, traditional clinician exams are sufficient and far less invasive.
The A-scan 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.
What is a B-Scan?
Similar to the A-scan, a B-scan (or brightness scan) is used in ophthalmology to produce a two-dimensional cross section of the eye and its orbit. It is most commonly used when a basic clinical examination isn’t revealing enough information.

I had my cataract surgery and lens implantation with Eye Consultants Clinic. What a beautiful experience! All the staff were very kind, helpful, and competent. Special thanks to the clinic manager for being so accommodating and caring in all of my inquiries. Thank you, Dr. Mohamed Awadalla for your dedication and for being best at what you do. Overall, I highly recommend Eye Consultants, they made sure that I get the best treatment possible.
I was a patient of Dr Ahmed El Khashab’s between 2018 and 2021, and had a retinal detachment surgery, a silicone oil removal surgery and a cataract surgery, as well as glaucoma surgery in another clinic but followed up with him. With no doubt in my mind, he is by far the best doctor I’ve ever come across. He is very patient, very informative and an absolute gem of a doctor. - Menna Aly
I had a cataract surgery in both eyes last week and now my vision is perfect. Thank you to the entire team at Eye Consultants Center and most especially to Dr. Ahmed El Khashab who performed my cataract surgery. It was an amazing experience and he is the best!
We are delighted to have an opportunity to express our gratitude and appreciation to Dr. Ahmed El Khashab and his staff for diligently caring for my mother's eye problems and her cataract surgery. They are not only most professional but always attentive to our needs and concerns. Dr. and his staff are eager to care for us as a hive of "busy bees". Thank you doctor.
I was diagnosed as having cataract in both my eyes and advised surgery.This was my very first experience and I was really nervous, but Dr Ahmed Al Khasheb assured me it will go well. I must say he is not only an expert in his field but also very kind and understanding. The surgery went well and now I have a perfect vision. I’m also thankful to the receptionists and the nurses at Eye Contact Center for being respectful and professional. I would definitely recommend this hospital and especially Dr Ahmed.
The whole team at Eye Consultants is very professional and Dr. Ahmed is special and recently performed cataract removal from both my eyes successfully. He has previously performed surgery on one eye to address a retinal detachment case. HIGHLY recommend him and his wonderful team.
