Cataract Eye Surgery in Londoon

Cataract surgery or lens replacement surgery is the removing of the natural lens of your eyes when there is opacification (a cataract). These days, cataracts are a common and age related problem that affect nearly half of people over the age of 65 which makes the surgery a frequently performed operation in the UK. If your eyesight is affecting your life, job, hobbies, or well-being, then the ophthalmologists at Optimal Vision will be able to replace the cloudy lens and help to restore clear vision within a few days.


At our clinic, our eye surgeons conduct cataract surgery as a day case. The surgery will be done under local anaesthetic in around 25 to 30 minutes per eye.

Your surgeon will create a small cut in the eye (usually 2.5mm) and remove the lens with advanced equipment including ultrasound. The replaced artificial lens is made of a non-reactive substance such as acrylic or silicone which will be placed carefully where your natural lens used to be.

When your vision is affected by cataracts, you may feel slow and uncertain when you undertake some tasks.

If your eyes are not functioning properly, cataracts may be blocking incoming rays of light from entering your eyes. Even when you wear new glasses, your vision won’t improve.

Our team will also have a look at your medical history, any medical conditions you may be suffering from and any other issues you have related to your vision. These tests and measurements will help us to decide the options when it comes to your cataract surgery.

You’ll be under the effect of local anaesthesia during the operation and no pain or discomfort is expected. The surgical procedure will take about 25 minutes per eye, after which you can go home when you feel comfortable, however we would recommend you be accompanied by a friend or family member for safety.

During the cataract surgery procedure, with the help of a laser and modern technology including ultrasound, the surgeon removes the cataract and replaces it with an artificial lens. This procedure is performed through a small incision of 2-3mm and it is painless.


Modern cataract surgery is an advanced method by replacing the lens of the eye using a microscope. The eye surgeon uses 2 to 3 micro-incisions which are 1.5 to 2.7mm in size. The surgeon can dismantle and combine the cataract through a specific method called phacoemulsification. After this, they will remove the cataract, leaving your lens capsule undamaged. An artificial lens will be placed within this capsule and the new lens is now replaced.


You will be given anti-inflammatory drops to use for at least two weeks as well as antibiotic drops. Use them as suggested by your eye surgeon.

You may continue driving once you are able to read a number plate at the required distance, our specialist will inform you when you are legal to drive. This is usually after a few days.

Daily bathing and washing your hair are OK after the first 24 hours but you should not get soap near your eyes for at least 1 week after the surgery. This is because it may cause irritation to your eye and rubbing it will disturb the wounds.

It is suggested you wear a clear eye shield during the night for at least two weeks which we will provide for you. This can prevent unconscious rubbing of your eyes while you sleep.

Your eyesight will begin to improve within a few days after the surgery. You will have blurred vision immediately after the procedure and most likely during the first few days.

If you are wearing strong correction in your other eye, then you might feel that the eyes seem to be 'unbalanced' during the time immediately after the procedure. Make sure you take extra care pouring hot drinks or using the stairs.


  • Bloodshot eye- Your eye may appear slightly red after surgery. It will become fully white and healthy typically within two weeks.
  • Allergy to post-operative drops - Most patients can tolerate the post-operative drops but some patients may be sensitive to preservative ingredients. If this is the case, then your eye surgeon can suggest preservative free drops.
  • Raised eye pressure- This will need temporary eyedrop treatment if your eye pressure is raised more than expected. It is quite common among patients who suffer from diabetes. Your eye surgeon may suggest additional eye drops for few weeks to lessen the chance of it recurring.
  • Cystoid macular oedema- This occurs when some inflammatory fluid collects within your retina, this condition is common amongst patients who suffer from diabetes. This fluid is usually temporary and will resolve with some extra eye drops after a few weeks.
  • Refractive surprise- Proper measurements called biometry scans are usually done as a part of the pre-operative evaluation. Your eyes curvature and measurements of the length are extremely important to selecting the right kind of lens. Even with the most accurate measurements, however the prescription may be different to what is expected. In this case correction with glasses will be needed. The implanted lens might need to be exchanged.
  • Posterior capsule rupture- The capsule holding your lens is a delicate structure and it can potentially be disrupted during the procedure. This may make surgery more complex and your surgeon may need to use a different type of lens. In rare occasions the surgery may be conducted in 2 parts rather than in a single sitting. It might be a good idea for the eye surgeon to remove the cataract in the first part itself enabling your eye to settle down in the 4 to 6 weeks before the new lens is implanted. It will require a longer time for the eye to recover although a positive result can be expected.
  • Corneal decompensation- Your cornea is the window at the front of your eye. With age, the function of your cornea begins to decline. Cataract surgery may cause further deterioration of this age related change which can result in a cloudy cornea. Mostly, this will be temporary and settle in time or with extra drops. There are certain cases when further surgery will be required to replace a part of your cornea.
  • Retinal detachment- This is extremely rare and uncommon after a cataract surgery however it is a known complication which will need further surgery with a retinal surgeon to be corrected. High short-sightedness usually carries higher risk of this complication.

Frequently Asked Questions About The Cataract Surgery

Cataracts occur when there is a cloudiness of the eyes natural lens which is normally known to lie inbetween the front and back areas of the eye.

Although most cataracts are known to develop over time slowly among people who are above 50 years of age, infants and younger patients may also have an uncommon condition called congenital cataracts, and this is only known to occur in rare cases.

Cataract surgery simply involves removing your cloudy natural lens and replacing it with a premium synthetic lens. This lens is specifically designed to improve your vision so that you rely less on glasses and contact lenses.

No - Since the synthetic lens sits within the eye, rather than on the surface as it is with contact lenses, you won't feel the synthetic lens in the eye whatsoever.

You should only go for your cataract surgery when your cataracts start affecting your everyday vision. In other words, if you have trouble driving, reading, and watching TV, then it is high time you spoke to an eye doctor.

There are no clear or concise ways to prevent cataract, as they are simply part of the ageing process and are caused by the natural build-up of protein in your eye's lens. Thanks to cataract surgery, they can be treated with little or no risk and can be controlled if done with the right eye care provider.

Just like it is with every other surgery, cataract surgery does usually come with some level of risk. However, it is the most commonly performed surgical procedure in London and the United States. Choosing an experienced surgeon with many years of practice will help to reduce this risk to the barest minimum.

Some of the risks of cataract surgeries may include infection of the eye, inflammation, glaucoma, swelling and redness of the eyes, secondary cataract, or loss of vision.

The short answer is no. However, you can manage the early symptoms of cataract with the help of your doctor’s recommendations and prescription until it is time to have your surgery.

In most cases, patients should be able to return to their usual activities after 3 days. Nevertheless, since every patient is unique and different, we make use of how severe our patient’s condition may be in making recommendations. Hence, your surgeon should be able to provide you with the best recommendation suitable for you.

Like earlier stated, you can expect your vision to start improving within a few days of your surgery.

Nevertheless, it may take a longer time for your vision to absolutely return to normal. However, if you wear glasses as a result of astigmatism, and don’t choose a lens that generally corrects cataracts and astigmatism; you will still need to wear glasses after your surgical procedure. The same applies to other vision problems or conditions. Make sure you speak to your surgeon on what you should expect after your surgery.

The cost of a cataract lens surgery will strictly depend on some factors: your choice of doctor, your prescription and your choice of lens. You should have a clear overview of your surgical cost after an initial consultation with your doctor.

Depending on your needs and what you want to achieve, you can talk to your eye doctor about advanced technology lenses that can be used to correct cataracts and other vision issues like astigmatism and presbyopia.

Your choice of lens can make a lot of difference to your vision after surgery. If you have astigmatism for example, then advanced-technology lenses that are effective in correcting both your astigmatism and cataract may be your best shot. For some other cases where the patient may have difficulty seeing things close due to presbyopia, there are also lenses available to help you ease this eye condition, without having to depend on reading glasses.

Very simple! Complete our short form or call us, and we will take it from there.
