Those suffering from cataracts experience a clouding of the natural lens inside the eye. The condition is very common and often inevitable as you age, with 60% of the population experiencing the visual complication as they reach their 60s.
Cataracts are a common visual problem. Often developing very gradually, the natural crystalline lens becomes clouded, causing vision to become misty. It the most common cause of vision loss in the world. The word “cataract” comes from the Greek word “Cataracti” which means waterfall. The lens can take on this appearance when the condition is quite advanced.
The clouding of the natural lens of the eye affects us all as we age. Some of us develop this condition earlier than others but with all of us now living longer, unfortunately, this has become one of life’s inevitabilities.
Fortunately, it is treatable, and advances in cataract treatment mean that the problem can be treated very effectively with a simple and safe procedure.
The lens of each eye needs to be clear in order for your eyes to work properly, so cloudy lenses adversely affect your vision. In a normal eye, the clear lens allows light to reach the retina at the back of the eye, which then communicates with the brain via the optic nerve – this is how we see. However, with a cataract, less light can reach the retina, so your vision is affected.
The problem tends to develop slowly over time. Eventually, cataracts result in a gradual loss of the clarity of vision. Often, patients may complain of:
As well as getting older, there are other factors that contribute to the likelihood of developing cataracts.
Age: Because they develop gradually over time, cataracts are much more common in older people
UV damage as a result of exposure to sunlight
Familial factors: cataracts run in families, so if close relatives suffer from the symptoms then there will be an increased risk to yourself
The only way to treat cataracts is through the surgical removal of the cloudy protein within the natural lens. There is no way to reverse or “cure” a cataract.
Cataract surgery is a very successful treatment option and is the most commonly performed procedure in the UK with over 300,000 surgeries being performed every year. The surgery takes around 30 minutes, and is performed as a day case under local anesthetic in most cases.
An ultrasound probe is used to gently break up and remove the cloudy protein from the natural lens, preparing the eye for an artificial lens to be inserted.
Additionally, it is now possible to remove cataracts using Femtosecond Laser Technology combined with ultrasound technology. This new generation of cataract surgery uses a special type of laser to help remove the cataract, reducing the manual element of the surgery. The laser, known as a femtosecond laser, is programmed to make precise incisions in exactly the right places within the cornea and lens. The cataract is then removed using a sophisticated ultrasonic device.
“If Apple did cataract operations, then they would do them like OCL do cataract operations. All the staff are knowledgeable and well organised. Everything went according to plan, the operation, recovery and aftercare. Many thanks for improving my eyesight.”
Cataract treatment risks are very small
Very rarely there is a complication associated with a surgery called posterior capsule opacification (PCO). This causes the vision to become cloudy due to the formation of a membrane over the new lens. However, this can be treated using a special type of laser which removes the membrane.
Other complications can occur but are much rarer. These include:
Despite this, it remains one of the safest surgical procedures in modern surgery and all of these complications will be discussed in detail prior to any treatment.
Cataract surgery is a safe and effective way to restore vision and serious complications are very rare. A national statistic shows that 97% of cataract surgery patients enjoy improved vision with no complications, however at Ophthalmic Consultants of London our success rate is 99.5%.
85% of our patients have better than 20/20 vision one month on from the procedure (the national average is 51%), and 100% of our patients have better than 20/40 vision (the legal driving standard) one month on from the procedure.
In 2018, OCL surgeons, Allon Barsam, Romesh Angunawela and Ali Mearza were voted by their peers as some of the UK’s best cataract surgeons following a National survey of eye surgeons by the Daily Mail. They are regularly consulted by industry and feature on advisory boards for new technologies. It’s a testament to our surgeons that we’re trusted the world over to test and use new technology, and that we’re involved in pushing lens and laser eye surgery to exciting new possibilities.
