Overview

Posterior Capsular Opacification (PCO) at The London Eye Clinic

Following cataract surgery, nearly 1 in 10 patients have thickening of the back of the posterior part of the lens capsule which holds the artificial lens implant in place. This is called posterior capsule opacification or PCO. PCO decreases the amount of light travelling through to the retina.

About Posterior Capsular Opacification (PCO)

What is posterior capsular opacification (PCO)?

Following cataract surgery, nearly 1 in 10 patients have thickening of the back of the posterior part of the lens capsule which holds the artificial lens implant in place. This is called posterior capsule opacification or PCO. PCO decreases the amount of light travelling through to the retina. This results in the vision becoming blurred and can cause difficulty seeing in bright light. If you have PCO that is affecting your vision, Mr Sherafat may recommend laser treatment to help clear your vision.

Treatment

Information on the procedure

The treatment involves using a type of laser, called YAG laser. YAG laser is a beam of focused light that can be targeted very accurately. In patients with PCO, the laser is directed at the thickened capsule behind the lens implant. The YAG laser delicately cuts a hole through the capsule (called a capsulotomy) without affecting the other parts of the eye behind or in front of the capsule. Making the hole in the capsule improves vision by allowing more light to pass directly to the retina.

 

What does YAG laser capsulotomy treatment involve?

Eye drops are used to dilate (widen) your pupil before the treatment. This can make your vision blurry for a few hours. An anaesthetic drop may also be used to numb the front of your eye so that you do not feel any discomfort. You will then be asked to place your head on the headrest of the laser machine. Mr Sherafat may use a contact lens to help keep your eye in the right position and to help focus the laser. Mr Sherafat will then activate the laser and use a series of laser pulses to make the hole in the centre of the capsule. Each laser pulse lasts a fraction of a second.

The treatment only usually takes a few minutes and during that time, you may see flashing lights or hear some clicks from the machine. You should not feel any pain from the laser itself.

Clearer, Brighter and the Colours are Wonderful

I just don’t know how to thank you for my improved eye sight. Everything is clearer, brighter and the colours are wonderful! Of course, I was a little fearful of the operation, but I had great confidence in you. The actual procedure was totally painless. The right eye could not have been more comfortable; in the left eye I had some very slight discomfort. Two days later the right eye was perfect and there was some ‘grittiness’ in the left; after one week both eyes are excellent.

About

About Cataracts

What is a cataract?

The best way to understand a cataract is to have an understanding of the structure of the eye.

The front of the eye is covered by clear structures i.e. the cornea and the crystalline lens, which together bring the image to a sharp focus on the retina, which lines the inside of the back of the eye.

The best way is to think of the eye is as a cinema, where the cornea and the lens are the projectors and the flat retina on which the image is focused is the cinema screen.

Whilst the cornea has a fixed curvature and shape, the lens is able to change its shape to bring objects of different distances to a sharp focus on the retina. A cataract is a condition where the lens of the eye loses its clarity and thus either prohibits light from passing through or misdirects light rays, thereby interfering with the projection of a bright and sharp image on the retina.

What is the treatment for cataracts?

The only definitive treatment for cataract is exchanging the lens of the eye with an artificial lens implant. This is what is referred to as cataract surgery or cataract extraction. Occasionally when symptoms are very mild you may find that spectacles temporarily resolve the symptoms.

Treatment

Information on the procedure

Cataract surgery involves removal of the crystalline lens (cataract) and replacing it with a clear artificial lens implant. It is normally carried out under a local anaesthetic as a daycase procedure with the patient being awake during the surgery.

After the pupil is dilated with eye drops and the eye is anaesthetised, a small (2-2.5 mm) self-sealing incision (opening) is made on the periphery of the cornea. A section of the thin capsular bag enclosing the lens is opened and peeled off. A fine ultrasonic probe is inserted into the eye, through the incision and used to fragment the lens into fine particles, which are simultaneously washed out of the eye. Once all the lens matter is removed an artificial lens is implanted into the empty capsular bag. Normally there is no need to use stitches. The artificial lens can stay in place indefinitely.

What happens in consultation?

You will undergo a full ophthalmic history and assessment to ensure your cataract is the main caue for your visual deterioration and to rule out or identify other co-existing causes for your symptoms. This includes measurements called biometry, which enable selection of the appropriate lens power, by Mr Sherafat. There are different types of lenses (monofocal, toric, multifocal) designed to meet patients different lifestyles and needs and during the consultation these options and pros and cons of all are discussed.
