Introduction

It has been noted that you have got thickening and cloudiness of the posterior capsule of the lens in your eye (posterior capsular opacification) which may be contributing to dimness of vision.

During Cataract surgery, when we remove your cloudy lens, we leave behind part of the bag (posterior capsule) of the lens to support the new intra ocular lens implant in place.

Following the operation

In the post-operative period, this capsule can become opaque and reduce vision. This opacity can start within a few months after cataract surgery and occurs in many people. Yag laser capsulotomy is the only non-surgical procedure
available anywhere to make an opening in the cloudy capsule. This allows more light to enter your eye, increasing the vision.

Procedure

  • It is done in the Eye Clinic outpatients department at Yeovil Hospital.
  • You come on the day of laser surgery, and you may eat and drink as usual. Take all your normal medication.
  • First nurses put in drops to dilate your pupil. Once the pupil is dilated, you are taken to the laser room where local anaesthetic drops are put into the eye.
  • The doctor will explain the treatment to you and ask you to sign a consent form.
  • The doctor will position you comfortably on the laser machine. You have to sit still with your forehead against a
    bar and your chin on the rest.
  • You will see bright lights and hear clicking noises.
  • You should not feel any pain.
  • The lasering takes about ten minutes.
  • After the procedure, you may be given eye drops and medication, for the pressure in the eye. You may be asked to wait for an hour after treatment for a pressure check.

Recovery

Because of the dilating drops and dazzle from the laser, your vision will be blurred initially. Visual recovery starts in a few hours. As your vision may be blurred for a period of time after the procedure you should arrange transport home and not drive yourself. In the days following laser surgery you may see floaters, which should progressively disappear.

Real expectations

The posterior capsule opening made with laser aims to improve the vision lost as a result of capsule opacification only. If the vision is already lost due to retinal problems or optic nerve damage, you may not appreciate any improvement.

Risk

It is a safe procedure, done routinely in the hospital. Although rare, complications may include the following:

  • Brief rise in intra-ocular pressure (pressure in the eye).
  • Increased risk of retinal detachment if the retina is weak.
  • Retinal swelling.
  • Dislocation of the implant.
  • Pitting on the implant.
  • Flare up of existing inflammation.

Consent

If you have read this information sheet and are happy to
proceed with the laser procedure, please sign the consent form
on the day.

After care

You must telephone the eye clinic if any of the following occur:

  • Severe eye pain which is not controlled after taking pain relief
  • Flashing lights when you move the eye
  • A dark curtain coming across and blocking your vision
  • Sudden blurring in vision
