Retina, posterior capsule opacification and glaucoma

Laser treatments – precise energy for different tasks.

‘Eye laser treatment’ covers several procedures. Depending on the condition, we stabilise the retina, open a cloudy lens capsule or change fluid drainage to lower eye pressure.

One tool, different treatment areas

What does a medical eye laser do?

A laser focuses light energy precisely. Depending on wavelength, pulse duration and target tissue, it can make a tiny opening, create a controlled scar or stimulate biological responses in the eye’s drainage area.

Treatment is usually outpatient and does not require a skin incision. That does not make it risk-free: preliminary examination, the right indication, precise dosing and follow-up are essential.

Six routes of treatment

Which procedure treats which disease?

The procedures differ fundamentally in where they act, their aims, preparation and follow-up care.

Retinopexia & Photocoagulation

Retinal laser

The laser creates tiny, precisely targeted tissue reactions. Around a retinal tear, it forms a firm scar intended to reduce the risk of retinal detachment. For selected vascular conditions or diabetic retinopathy, treatment targets areas of the retina with poor blood supply or leaking vessels.

YAG-Capsulotomy

YAG laser for posterior capsule opacification

After cataract surgery, the capsule behind the artificial lens may cloud over. A YAG laser makes a central opening without a skin incision, allowing light to reach the retina freely again.

Selective laser trabeculoplasty (SLT)

Laser treatment to lower eye pressure

Short laser pulses act on the eye’s natural drainage tissue. They can lower pressure in open-angle glaucoma or suitable cases of ocular hypertension.

YAG-Iridotomy (YAG-ID)

Laser iridotomy

For a narrow drainage angle or one at risk of closing, a small opening is made in the iris. This balances pressure between the eye’s chambers and can relieve or prevent a pupillary block.

CPC/cyclodiode

Cyclophotocoagulation

Laser energy is applied from outside the eye to the ciliary body, which produces aqueous humour. Reducing fluid production aims to lower pressure in selected glaucoma cases.

Subthreshold retinal treatment

Micropulse laser

A micropulse laser delivers energy in very short bursts, with cooling intervals between them. Treatment stays below the threshold at which visible scarring occurs. It aims to stimulate the retinal pigment epithelium so that fluid beneath the retina can drain more effectively.

Micropulse laser for central serous chorioretinopathy (RCS / CCS)

When fluid accumulates under the centre of the retina.

Central serous retinopathy (RCS), often called central serous chorioretinopathy (CCS) in medical publications, mainly affects the macula and choroid. Fluid collects beneath the retina and may cause blurred vision, distorted lines, a grey patch in the visual field, changes in the perceived size of objects or reduced contrast vision.

Many acute cases resolve on their own within a few months. If fluid persists, returns or threatens lasting damage to the pigment epithelium and photoreceptors, we assess treatment options using OCT and, where needed, fluorescein and ICG angiography.

How the micropulse laser works

Brief pulses alternate with cooling intervals. Unlike conventional visible laser coagulation, no permanent retinal scar is intended. Treatment targets carefully mapped leakage or fluid areas.

Who may benefit

Treatment may help selected persistent or recurrent cases, particularly when the imaging and leakage site fit the procedure. Acute central serous retinopathy is not automatically treated with laser straight away.

What are the alternatives?

Depending on the findings, options include observation, conventional focal laser treatment outside the fovea or photodynamic therapy. In the PLACE study of chronic central serous retinopathy, half-dose photodynamic therapy was more effective overall than the micropulse procedure studied.

What we check afterwards

Visual acuity, symptoms and fluid on OCT guide the assessment. The effect develops over time; persistent fluid may require repeat or alternative treatment.

Before the laser

First the cause, then the treatment.

Similar symptoms can have very different causes. We use laser treatment only when the diagnosis and expected benefit support it.

Accurate diagnosis

Slit-lamp and retinal examinations, pressure readings and disease history determine whether laser treatment is appropriate.

Retina and macula

Before retinal treatment, we dilate the pupil and examine the peripheral retina carefully. OCT or vascular imaging may provide additional information.

Glaucoma diagnostics

Pressure readings, drainage angle, optic nerve, visual field and OCT help establish the type and stage of glaucoma and the target pressure.

Recognising posterior capsule opacification

Before YAG capsulotomy, we confirm that capsule clouding, rather than the retina, cornea or optic nerve, is causing the reduced vision.

Assessing Risks

Planning takes account of previous retinal tears, high myopia, inflammation, medicines and earlier operations.

Agreeing a treatment goal

We explain whether the laser aims to improve vision, lower pressure or prevent deterioration.

Outpatient treatment

What happens on the day of treatment.

The laser application often takes only a few minutes. Please allow additional time for preparation and checks.

Preliminary examination

We check visual acuity, pressure and the area being treated. The pupil may be dilated or constricted depending on the procedure.

Anaesthetic eye drops

The eye’s surface is numbed locally. Many procedures use a contact lens to keep the eye still and focus the laser precisely.

Laser treatment

You usually sit at a device similar to a slit lamp. You see flashes and may hear clicks. The duration depends on the procedure.

A direct check

After laser treatment, we check pressure, the retina or the treated tissue’s response, depending on the procedure.

Aftercare plan

We explain drops, rest, follow-up and warning signs. Change existing glaucoma drops only on medical advice.

What changes afterwards

Follow-up examinations tailored to the procedure.

Follow-up care depends on the tissue treated and your individual risk.

Retinal laser

Scarring takes time

The stabilising effect is not immediate. Follow your personal instructions on activity and warning signs until your check-up. New flashes, many spots or a shadow still require urgent care.

YAG-Capsulotomy

Vision may become clearer quickly

Clouding and small moving spots may be noticeable at first. Pressure and retinal risk determine the checks needed.

SLT

Checking the pressure response

Pressure may not fall immediately. Continue your prescribed glaucoma drops until your treating team advises a change.

YAG-Iridotomy

Check opening and drainage angle

Anti-inflammatory drops and a pressure check may be needed. Ongoing glaucoma monitoring remains important after successful iridotomy.

CPC

Closer follow-up

We monitor inflammation, pressure and visual function. Change drops or tablets only on medical advice.

For all procedures

Your examination results guide the decision

Follow-up intervals and medicines are chosen individually. Feeling well immediately afterwards does not replace your scheduled check-up.

After treatment

What can be temporary – and what is urgent.

These notes are general guidance. Your personal aftercare instructions take priority.

Often temporary
  • Blurred vision caused by examination or dilating eye drops
  • Glare sensitivity and coloured afterimages
  • A mild foreign body sensation after use of the contact lens
  • Occasional moving spots after YAG treatment
  • mild redness or feeling of pressure

Drive again only when your vision has recovered sufficiently. Use prescribed drops as instructed.

Urgent warning signs
  • sudden marked visual deterioration
  • severe or increasing eye pain
  • severe redness, nausea or headache
  • many new black dots or flashes of light
  • a dark curtain or shadow in the visual field

Seek immediate assessment by an ophthalmologist. Do not wait for your next routine appointment.

Guidance for urgent symptoms
Benefits and risks

What will be discussed before the decision.

The types of complications and how often they occur vary with the procedure and the condition of your eye before treatment.

General reactions

  • temporary inflammation or irritation
  • Increase or fluctuation of intraocular pressure
  • Glare, afterimages or temporarily blurred vision
  • Insufficient effect and retreatment
  • Rare bleeding or damage to neighbouring structures

Retinal risks

  • New floaters or an increase in existing floaters
  • Reduced visual field or low-light vision after extensive photocoagulation
  • Swelling of the macula
  • Retinal tears or detachment despite treatment
  • Rarely, unwanted laser effects on the macula

What the procedure cannot achieve

  • Laser treatment cannot restore retinal cells that have died
  • SLT or CPC cannot always avoid additional drops or surgery
  • iridotomy does not resolve every form of angle closure
  • It does not treat other causes of poor vision
  • Long-term follow-up remains necessary

We discuss your individual risks before treatment. These depend on factors including glaucoma stage, retinal health, myopia, previous operations and other conditions.

Frequently asked questions

What patients want to know.

Does laser treatment hurt?

Drops numb the eye’s surface. SLT, YAG capsulotomy and many retinal laser treatments usually involve flashes or mild pressure. CPC may require stronger anaesthesia. Sensations vary between patients.

Can I drive again immediately after that?

No. Please make other travel arrangements. Dilated pupils, glare and temporarily blurred vision can affect your ability to drive. Wait until your vision has recovered sufficiently and you meet the legal requirements before driving again.

Does SLT replace my glaucoma drops?

Some people can reduce drops or start them later; for others, pressure does not fall enough. Change your drops only after the agreed pressure check and medical advice.

Can a posterior capsule opacification re-emerge?

The opening made in the posterior capsule with a YAG laser normally does not cloud over again in the same way. Other eye conditions can still affect vision later.

Does retinal laser treatment reliably prevent detachment?

Laser treatment can substantially reduce the risk, but cannot eliminate it. New flashes, many spots or a shadow need immediate assessment even after treatment.

Why are follow-up checks still needed after laser treatment?

The effect may take days or weeks to develop, may fade or may be incomplete. The underlying retinal disease or glaucoma also remains.
