On World Sight Day (Oct 10th), medical professionals at Moorfields explain how care, support and treatment can help visually impaired or blind people lead full and independent lives
9 October 2019, Dubai: Visually impaired or blind people can live full, active and, most importantly, independent lives if they have access to the right treatment, care and support.
This is the vital message experts at Moorfields Eye Hospital Dubai are hoping to spread throughout the UAE community ahead of World Sight Day on 10 October.
The days of individuals with poor or impaired eyesight being housebound or even dependent on others for help are long gone said Dr. Luisa M. Sastre, Specialist Ophthalmologist in Medical Retina.
“No matter the seriousness of their vision condition, nowadays there is definitely a solution available be it in the form of a smartphone app or more basic assistance such as braille training,” said Dr. Luisa. “There are many optical and non-optical devices that can be catered to their daily lives.
“If a person’s condition is assessed thoroughly and they are dispensed the right devices or given the right training and support, they can lead an independent life very easily.”
Dr. Luisa said the UAE Government has rolled out Smart Technologies that actively assist blind and visually impaired in getting around Dubai using public transport.
“This technology helps People of Determination by converting written information into voice information including schedules and triggers directional signals and alerts for metro gates, stairs, escalators and station gates.
“The technology is compatible with tactile marks on the ground that mark out an area for walking cane users. A lot can be done with software and special apps, like walking canes with GPS tracker, voice to text mode for phones, dedicated walking lanes for visually challenged people in malls, parks, beaches or roads.”
Ophthalmologists at Moorfields regularly treat patients suffering from deteriorating vision or loss of eyesight. While this can be a hugely traumatic experience, Dr. Luisa said Moorfields offers a wide range of support and care services available at the hospital.
These include everything from basic braille training [a form of written language in which characters are represented by patterns of raised dots felt with the fingertips] to comprehensive rehabilitation work where appropriate.
“Support services in things like braille are essential as they enable patients to use a computer or telephone once the keyboard has been adjusted to feature braille,” said Dr. Lusia. “There has also been talk of introducing braille labels to medications in the UAE, which would be a huge benefit.
“Training is available via Moorfields teams of experts for blind and visually impaired patients. This can be very useful to help people overcome problems in their daily routines, particularly with things they took for granted like dressing, putting on make-up, cooking and glare controls for TVs or electronic equipment etc.”
Moorfields prides itself on making its range services available to patients after their condition has been fully assessed by a team eye care specialists, said Dr. Luisa
“Assessment does not stop in the hospital. It needs a team of professionals to deliver good services to the patient in order to help them cope with what can be a very stressful time in their lives.
“Moorfields expert team consists of an ophthalmologist and a low-vision specialist who can determine the cause or a patient’s vision problems and the best course of action for treatment.
“The next step for those with deteriorating vision is to see an occupational therapist or a rehabilitation teacher,” said Dr. Luisa.
“This can also feature a social worker, counselor and assistive technology professional. The combined efforts of these professionals will help to ensure that the loss or vision, or loss of quality of eyesight, is no barrier to leading an active life and that with some adjustments patients can live constructively and independently in their own homes or with family.”

Can Astigmatism be Cured?
This week’s blog on ‘Can astigmatism be cured?’ has been contributed Dr. Osama Giledi, Consultant Ophthalmologist, Specialist in Cataract, Cornea and Refractive Vision Correction Surgery.
What is astigmatism?
Astigmatism is a common kind of refractive error. It is not an eye disease, it means the surface of the cornea is not spherical, or not completely round “the eye is shaped like a Rugby ball, not a football ball.” With astigmatism, the eye does not focus light evenly onto the retina causing blurring of the image formed at the back of the eye.
Causes of astigmatism?
The specific cause is normally unknown although genetics can play a part. Sometimes astigmatism can develop after an eye injury, surgery or because of an eye disease Astigmatism is not caused by reading in bad light, using a PC or watching a lot of TV.
Astigmatism can affect both children and adults, it is usually non progressive and associated with myopia or hyperopia. If the astigmatism is getting worse, then it is very important to see a corneal specialist to a have corneal scan in order to rule out the weaker cornea (Keratoconus) as it is a progressive disease and there is treatment to stop it, especially if detected early, to save the vision.
What are symptoms of astigmatism?
Patients with astigmatism notice a blurred/distorted vision especially at night driving or have frequent headaches, increased eye fatigue, eye strain and squinting.
How is astigmatism diagnosed?
Astigmatism is usually found during eye glasses examination. Most of astigmatism are regular, however some astigmatism are irregular and caused by diseases affecting the cornea such as Keratoconus or corneal scar. Eye examination and a corneal scan is needed to rule out disease causing the astigmatism
Can you have astigmatism and not know it?
It is possible to have mild astigmatism and not know about it. This is especially true for children, who are not aware of their vision being other than normal. Some adults may also have mild astigmatism without any symptoms. Also many people wear glasses for myopia or hypermetropia and have mild astigmatism but were not informed about it.
Treatment: How is astigmatism corrected?
Astigmatism can be rectified with eyeglasses, contact lenses, or surgery.
Multiple ways of correcting astigmatism are:
- Eyeglasses are the simplest and safest way to correct astigmatism.
- Contact Lenses; need special Toric soft contact lens or hard contact lens.
- Refractive Surgery aims to correct astigmatism permanently in association usually with myopia or hypermetropia. There are various types of refractive surgeries to treat astigmatism using:
- Femto LASIK to change the shape of the cornea permanently
- Toric intraocular implant which we use in severe cases who is not suitable for laser vision correction or patient with weak cornea such as Keratoconus eye.
Astigmatism can also be corrected during cataract surgery by using toric intraocular implant so patient does not need to wear glasses after the procedure.
For astigmatism caused by corneal diseases, the treatment can be by different options depending on the disease and level of astigmatism. Options can be surgical cuts in the cornea (now by using femtosecond laser instead of knive), Eximer laser removal of irregular corneal surface and scar, insertion of specific intracorneal rings and lastly by replacing the diseased cornea with corneal graft
