What is a Cataract?

What is a Cataract?
LaserVision Consultant Ophthalmologists Professor Harminder Dua and Mrs Dalia Said discuss the causes and treatments of this common condition.

The eye has a crystalline transparent lens more or less similar to the lens of a camera which focuses one third of the light on the retina. This is the sensitive film of the eye which transmits the image for the brain to process so that we can see it.

cataract is a clouding of this crystalline lens most commonly due to age, however it can be caused by trauma, prolonged use of steroids (as topical eye drops or systemically), some systemic diseases such as diabetes or even as a congenital birth defect.

In the early stages of developing a cataract, patients often complain of reduced vision (especially at night), some glare while driving or inability to read.

Cataract is usually very slowly progressive and can take a long time to affect vision.

When the cataract is severe enough to interfere with vision, surgery can be performed to improve vision. The opaque natural lens is removed through a small incision in the eye and the lens is fragmented by a specialised ultrasound machine and aspirated. A plastic lens is then implanted inside the eye to replace the original crystalline lens.

The power of the plastic lens can be tailored to focus the light for distance or near vision, or in some cases a multifocal lens – a lens that can focus light for both distant and near vision can be inserted to help patients see at variable distance without the need for glasses.

Cataract surgery is the most established operation performed in the body and has a short recovery time with a 95 percent gratifying result.

Dr Tappin and the team at LaserVision were amazing. I underwent Lasik corrective surgery and the process could not have been smoother. I was guided through the process with care and professionalism throughout. My results have been outstanding. I could not have asked for more from the team at LaserVision and I am truly grateful for my new vision.

Utterly professional and caring from start to finish. I was quite nervous about having laser but am so pleased with the results. There has always been someone to advise and support every step of the way and patient care and well being really is the priority here. Thank you for looking after me and my eyes so well.

Dr Jayaswal has been amazing and changed my life. He made me feel so comfortable and relaxed in his care at the first meet, to remembering me with a personalised greeting, calmly explaining the procedure and reassuring me all the way through the surgery. I couldn’t recommend him enough for Lasik eye surgery - I now have perfect vision, a real dream come true! Thank you so much!

I had lens replacement surgery. After being both short sighted and long sighted for decades I can now see near and far without glasses or contact lens. It really is amazing. The care was great and so far the recovery has been easy.

Amazing service from start to finish, I had LASIK surgery in August this year after years of consideration I finally took the plunge and went for the surgery with Mr Tappin. Mr Mike Tappin and his team were brilliant from the consultation right through to the surgery and aftercare. Mr Tappin and his team were very reassuring throughout the surgery and put me at ease every step of the way. If you are thinking about having laser eye treatment or at the start of your journey with it, I would highly recommend seeing Mr Tappin and his team!
