Micropulse is a laser that is designed to treat glaucoma. It uses a concentrated beam to target the area of the eye that produces fluid (ciliary body). Micropulse is a gentle laser than uses less energy when compared to another type of laser, cyclodiode, which is normally used when other treatments have failed.
Glaucoma can be caused by a high pressure in the eye that is either due to poor drainage of the fluid out of the eye or too much fluid being produced in the eye. Micropulse targets the fluid production of the eye and uses short pulses of energy with periods to allow the tissue to recover. By targeting this area of the eye, the aim of the laser procedure is to reduce the overall eye pressure.
The procedure takes 4-6 weeks to work fully.
Micropulse can help to prevent or slow further glaucoma damage.
Micropulse has been found to reduce eye pressure by 33% in at least 70% of individuals. This may mean that you don’t need to use as many glaucoma drops.
Effects of the treatment are not thought to be permanent and may wear off slowly over months to years. If desired, Micropulse can be repeated.
On arrival, Mr Agarwal will speak with you about Micropulse again and if you agree to go ahead with the procedure, will ask you to sign a consent form. He may check the pressure in the eye to ensure no other changes he has tried with you have brought your pressure within its target range.
It may be helpful to bring a friend or family member with you to help get you home at the end of the procedure. Usually, you can go home on the same day as this procedure and will have a follow-up appointment arranged to ensure the treatment was effective.
Normally, Micropulse is performed under local anaesthetic, where the eye is numbed with drops and then a small injection is made to further numb the eye. The anaesthetic may temporarily affect your vision.
If you’re very nervous about the procedure, sedation or general anaesthetic are options you can discuss with Mr Agarwal.
The procedure takes 10-15 minutes and during this, a small probe is used to apply the laser treatment and is placed against your eye. A protective eye covering may be placed over your treated eye at the end of the procedure.
After the procedure, you should continue with any glaucoma medications you have been previously prescribed, unless directed to stop by Mr Agarwal. If you are uncertain when you get home please get in touch with the clinic.
Mr Agarwal may recommend some anti-inflammatory medications or eye drops to help the eye settle.
As the eye recovers from the laser, you may find it red and uncomfortable and your vision may be slightly blurry for up to a few weeks after; however, this should improve with each day and over the next 1-2 weeks your eye should return to normal.
Most people take some time off work to recover after the procedure, this is often 1-2 weeks, but depends on what you do for work and how your eye responds to the treatment.
It is safe to resume your normal activities after the procedure and you are able to fly after the procedure.
Mr Agarwal may book in a series of appointments with you following the procedure to ensure the eye is settling as expected.
Serious complications following Micropulse are very rare.
Commonly, patients report having blurred vision which slowly improves. This normally occurs in 1 in 5 patients.
For some individuals, the treatment may need to be repeated or may not lower the eye pressure to the target range.
The laser may cause your pupil to become dilated (bigger), and this typically improves over the next 2 months.
Although very rare inflammation can occur in the treated eye or in the untreated eye.
If you experience any other symptoms including sudden loss of vision, pain or worsening of the blurring of vision in either eye please do not delay in contacting the clinic or seeking assistance immediately.
Alternatives to Micropulse are available, including surgical options. If Mr Agarwal thinks Micropulse is an option in your treatment, he will discuss this with you as well as any alternatives, including no further treatments. If you chose not to have treatments you may find your eye is further affected by glaucoma.
