IN THIS VIDEO I PROVIDE A BRIEF EXPLANATION OF CATARACTS

Everything you need to know about cataracts

FIND OUT MORE ABOUT CATARACTS AND WHAT YOU ARE DEALING WITH

Cataracts are responsible for 51% of world blindness, which represents about 20 million people per year (WHO, 2010).

A cataract is the cloudiness of the natural crystalline lens inside your eye. It can feel as though you are looking through fog or a dirty camera lens.

Initially, your eye prescription starts to change. Later, your vision becomes misty and cloudy. At this stage, you cannot correct your vision with glasses.

When a cataract starts to impair your vision significantly, the only treatment is the surgical removal of the lens affected and the insertion of a new artificial lens.

  • Difficulty seeing in dim lighting or darker conditions like night time driving
  • Colours appear dim and faded
  • Vision becomes progressively worse, and you may find your glasses are no longer useful
  • Bright lights may be dazzling, and halos or rings may appear around them
  • You may feel as if you are looking through a misty window with a yellow or brown tinge

The back of the eye is called the retina; this works like the film in a camera. Both the cornea (the transparent front window of the eye) and natural crystalline lens act like the lens in the camera. When light is focused and hits the retina, an image is taken and sent to the brain.

When you are young, the lens in the eye is so elastic it moves very well. This movement is called accommodation and is comparable to the autofocus function in a camera. Accommodation enables you to read the small print as well as see distant objects comfortably. As you age, the lens loses its elasticity and is no longer able to see small print. You will typically notice this at around the age of 40 and above. 

Most people, when faced with this challenge, begin to use reading glasses. The power of reading glasses must increase with increasing age. However, there is a limit. Eventually, when the lens loses its elasticity, it begins to opacify (cloud over) and lose its clarity. This typically occurs when you are around 50. At this stage, you might start to lose some contrast sensitivity and the ability to see vivid colours. Cataracts can develop in both eyes and can vary in their developing between the two eyes.

Types of Cataracts:

Age-related cataracts

Age-related cataracts are the most common cause of blindness. Cataract formations occur when the natural crystalline lens inside your eye becomes cloudy, misty and it feels as though you are looking through a dirty camera. Developing a cataract is a part of the natural ageing process along with presbyopia (the loss of close-up vision). Age-related cataracts usually occur in those over the age of around 60, it can happen in one eye or both your eyes and tends to get progressively worse with time.

A traumatic cataract

Traumatic cataract can appear when there is damage that affects the natural crystalline lens. Damage is usually a result of an eye injury. This kind of cataract can impede the vision in the same way. We can remove it with surgery.

Congenital cataracts

Congenital cataract has the potential to lead to blindness and irreversible damage to the visual system if not addressed within 6-8 weeks of birth. Cataracts in new-borns are rare and affect 3-4 per 100,000 children in the UK. It accounts for 5% to 20% of blindness in children worldwide.

A developmental cataract

A developmental cataract starts at a young age and can progress to become visually significant enough to require surgery. Any cataract or lens opacity that is present in a child less than 12 years of age could lead to permanent loss of visual potential in the affected eyes unless treated. Sometimes, occlusion therapy by patching the unaffected eye to sufficiently stimulate the affected (cataract) eye. Surgery ultimately becomes necessary.

A secondary cataract

A secondary cataract develops at any age and is usually the consequence of a disease, irradiation or medications. Glaucoma and diabetes are known conditions that contribute to cataract development. Steroids are one of the medicines that are known to cause cataracts, mainly posterior subcapsular cataracts (a type of cataract where the opacity lies along the back surface of the lens). Diabetes control can slow down the progression of cataract, but unfortunately, we cannot reverse cataract development. At this stage, surgery becomes the only option.

How to prepare for cataract surgery

Before cataract surgery, it is essential to have a thorough consultation.

At the consultation, we will:

  • Perform a comprehensive eye exam to check the overall health of your eyes
  • Identify any risk factors or reasons why you should not undergo surgery
  • Discuss aspects of your occupation, hobbies and lifestyle to ensure your expectations of the treatment are attainable
  • Perform several tests and scans to accurately determine the amount of short-sightedness, long-sightedness and astigmatism you have before surgery.
    We will also take additional measurements so that we can select the best implant for you.

The first step in cataract surgery is to ‘wash out’ the cataract using a technique called phacoemulsification. This method involves using a tiny device that vibrates at ultrasound speed to break the lens into small particles. I then remove the particles through a tiny slit no larger than 2.40 mm using a little vacuum.

I use the best available microscopes and the most advanced phacoemulsification devices to ensure the best and safest outcomes.

After I remove the cataract, I implant an intraocular lens inside the eye’s capsule bag (that is the capsule or shell left after I removed the cataract). I determine the type and power of the lens implant in advance.

During the pre-operative consultation, I will discuss with you your intraocular lens implant options. Depending on your needs and goals, I might use a monofocal lens implant, a multifocal lens implant, or another type of implant.

Can you prevent the incidence of cataracts?

  • Certain nutrients and nutritional supplements may reduce the risk of cataract development like consuming vitamin E found in almonds, spinach and other green leafy vegetables, sunflower seeds, carotenoids lutein and zeaxanthin from food and nutritional supplements.
  • Antioxidants like vitamin C and omega-3 fatty acids may also lower the risk or delay cataract formation.
  • UV light is known to accelerate the development of cataract and therefore, wearing protective sunglasses can be useful.

Tareq Kass Hout, Keratoconus
“I am glad to be with Mr Hamada. I am glad to be examined by Mr Hamada who acts responsibly and professionally. I never had this experience before from a previous ophthalmologist. I am thankful to Mr Hamada for the successful diagnosis and treatment of my case.”
Ghiath Sumainah

“What a Consultant. Dr. Hamada is a man who was born for this profession. As soon as we walked into the room you felt that you had met a man who was gentle and kind. His demeanour was of a man who knew his trade. He speaks in a way that you will understand. He explains exactly what is wrong and the way he will help fix it for you.”

Sam Brock

“My eyes got really sore, tired and gritty feeling this year. It kept getting worse for about 6 months and every time I thought about it, I kept thinking it would eventually go away, but it just didn’t budge. So I want to say a big thank you to eye doctor Mr Samer Hamada who finally sorted me out! Apart from the eye tests I expected, he also took a really personal approach. I appreciate that he asked questions about my whole diet and lifestyle which helped him to quickly figure out why my eye surface was inflamed. I now have simple steps I can take to reduce the inflammation through diet and lifestyle changes which I’ve now been doing for 2 weeks. I also have been using the special non-preservative eye drops and gels that Mr Hamada provided. My eyes are already feeling so much better and I’m so relieved to have had help to sort this out. If you’ve been noticing your eyes getting dry – don’t wait to sort it out as it keeps getting continually worse and you can find relief very quickly with the right help.”

Laura Livesey, Dry eye

“Mr Hamada’s London Eye Care and his team are a delight. Nothing was too much trouble and the help, support, advice and guidance before during and after the surgery was all world class. I have worn glasses since the age of 13 years and had the onset of cataracts for the last five so it has all been very much a life changing experience to be free from glasses once more.”

Timothy Thompson

“We saw Mr Hamada after our 14-year-old son was diagnosed with keratoconus by another specialist. Mr Hamada talked us through the pros and cons of the cxl epi off and epi on procedures, he answered all our many and detailed questions without rushing us and as openly and honestly as possible. We opted to go ahead with cxl epi off with Mr Hamada. Our experience with Mr Hamada and his team, from his incredibly informative and supportive Secretary Joanna, nurse Mimi and Mr Hamada himself who was incredibly reassuring and put us and our son at ease both before, during and after the procedure, and at each follow-on appointment, has been the best possible. I would go so far as to say that he and his team are by far the best medical team I have ever experienced. I recommend him highly and would be happy to speak to anyone considering an expert in this field.”

Lisa & George, Keratoconus

“I would not hesitate to recommend Dr Hamada and his team. From the first call to inquire about booking an appointment to booking it, I was so impressed with his wonderful secretary Joanna- she really is worth her weight in gold, her lovely manner and care made me decide to go for this clinic. Dr Hamada was a lovely man with a very kind and thorougher way about him – he put my 4-year-old daughter at ease. The appointment was lengthy but at no point were we rushed and able to ask as many questions- things were explained so well. I would have no hesitation at all to recommend anyone to use Dr Hamada and his team- I have already recommended to some other parents.”

Amy

“Mr Hamada, his assistant Joanna and his ophthalmic technicians provide a caring, efficient and high quality service. From the admin through to the surgical aftercare we were very well looked after and we had a high degree of confidence in Mr Hamada’s abilities. Our daughter’s cataracts have been corrected (under general anaesthetic) and her quality of life has improved substantially. You also feel well cared for throughout – the human touch is vital in healthcare, but not always delivered, so well done and thanks to all of the team.”

Nat & Rich
“We were referred to Dr.Hamada by one of the UK experts. The expert himself admitted that Dr.Hamada was better than him!! We were not disappointed at all. Dr. Hamada was excellent with my child. His communication skills and knowledge were exemplary. He gave us clear management plan and would not hesitate to recommend him.”
V Nama
“Dr Hamada is an excellent, highly competent doctor with a very kind and sympathetic manner. His reputation for successfully treating dry eye patients seems unparalleled. His team are all extremely friendly and helpful, especially Dr Hamada’s PA Joanna, making the overall experience better than anywhere else I’ve been!”
Isla Cully, Dry eye
“Appointment setting and follow-up were very efficient and well managed. Mr Hamada was kind, reassuring, knowledgeable and had a very warm manner with my young son, making him instantly feel at ease. I feel that we can trust him and that he will finally be able to solve my son’s long-term eye problems that have stumped other eye doctors.”
Kathryn
“A real care provider – true in letter and spirit. After having seen few other consultants we were lucky to see Mr. Hamada. He treated my mother’s eyes and the prolonged inflammation finally went away. My mother went on to receive a corneal graft. Mr. Hamada and his clinic are simply wonderful. Their response is immediate every time even if it’s the weekend. Mr. Hamada puts a lot of personal attention answering every question very patiently and alleviating any fears. His manner is so kind that puts his patients completely at ease. This caring trait continues in the rest of his staff especially his assistant Joanna. I really can’t thank them enough. I thoroughly recommend anyone with eye problems to go to Mr. Hamada. You couldn’t be in better hands. He has treated my mother who is a long sufferer of eye problems. I am grateful always to Mr. Hamada and Joanna for all the support they have provided throughout.”
