Posterior Capsular Opacification
Posterior Capsular Opacification (PCO) is a common complication after cataract surgery. PCO occurs as cells remaining after cataract surgery grow over the back of the bag that houses the new artificial lens. It’s essentially the healing process of the eye building up scar tissue. The effects of PCO are very similar to symptoms of cataract with blurred/cloudy vision or glare. Patients often state their vision is ‘milky’.
Treating PCO is common and straightforward and happens in the outpatient department using a state of the art class 4 laser. The procedure takes about 1 minute, is pain free and minimally invasive. Its not like having your cataract operation but more like an outpatient examination.
This is a one-off laser treatment and allows your vision to return to normal within a day or so.

What are the risks of laser treatment?
- Retinal detachment – the retina, which is the inner lining of the eye, can become detached. If untreated, this can lead to reduced or complete loss of eyesight, but if detected early it can usually be successfully treated. This happens in 1 to 2 in 100 patients
- Macular oedema – the retina can become swollen causing blurring of vision. This can be treated medically but may take several weeks to improve. The chance of macular oedema after laser capsulotomy is 1-2%, but may be higher in diabetic patients.
- Worsening of glaucoma or causing glaucoma (raised pressure) in the eye. This usually can be medically treated and has an incidence of 1.5% after capsulotomy.
- Rarely the lens may be damaged by the laser causing visual problems. In exceptional circumstances, the lens may subsequently need to be changed.
- Very rarely, additional medical or laser treatment may be needed after the procedure to obtain the best vision.
How is the procedure carried out?
- Your vision will be checked, so please bring your glasses with you.
- Drops to dilate your pupil will be put into one or both eyes, which will blur your vision for several hours.
- You will not be able to drive home after the drops, so please bring a companion or make suitable transport arrangements
- The procedure is performed with the laser machine connected to a normal slitlamp (microscope).
- A contact lens is placed on the eye to focus the laser beam and keep the eye open.
- The procedure lasts approximately 5-10 minutes, during which time you will hear beeping noises and experience bright lights.
- There is minimal discomfort, if any.
What happens after the YAG laser and when can I drive again?
- Your vision will be blurred after the treatment, but should improve over the following few hours.
- If you experience a sudden shower of floaters, flashes of light in the eye, or the feeling of a curtain coming over your vision, you should contact the Community Eyecare on the number provided as this may indicate a retinal detachment
- You should also contact the eye unit if you experience severe pain or loss of vision after the laser treatment.
- Certain patients will require follow-up appointments in the outpatient clinic. Before you leave, the laser operator will advise you whether another appointment is needed.
- You may resume driving the following day
- You may visit the optician a week after the treatment to check if your glasses need changing.
