Retinal laser
Retinal laser treatment is used to specifically treat pathological changes in the retina—such as retinal holes, retinal tears, or vascular changes associated with diabetes.
The goal is to stabilize the retina, prevent further damage, and preserve vision as much as possible. In cases of retinal holes or tears, the laser can “seal” the affected area, thereby reducing the risk of retinal detachment.
Common causes and risk factors
Retinal laser treatment may be necessary for various retinal conditions, particularly:
- Retinal holes or retinal tears
- increased risk of retinal detachment
- diabetic retinopathy
- Vascular occlusions or leaky blood vessels
- Changes in the peripheral retina
- Consequences of a vitreous detachment
- severe nearsightedness
Retinal holes or tears are often caused by age-related changes in the vitreous humor, disease, or injury. If fluid enters the space beneath the retina through a tear, it can lead to retinal detachment.

Diagnosis
The diagnosis is made through an eye exam. Depending on the findings, visual acuity, the back of the eye, and the retina are examined in detail after the pupil has been dilated.
In addition, retinal photography, OCT, fluorescein angiography, or ultrasound may be used. It is particularly important to carefully examine the peripheral retina, as retinal holes or tears often develop there without being noticed.
Retinal laser treatment
During laser treatment, targeted laser pulses are applied to the affected areas of the retina. This creates small scar points that stabilize the retina or treat abnormal blood vessels.
Retinal laser treatment can be used to seal retinal holes or tears, prevent retinal detachment, treat leaking blood vessels, or slow the progression of diabetic retinopathy.
The procedure is usually performed on an outpatient basis. The eye is prepared with eye drops, and the pupil is dilated. Afterward, vision may be temporarily blurred.
When is a laser not enough?
Retinal laser treatment is particularly effective for retinal holes, retinal tears, or certain vascular changes. If the retina has already partially or completely detached, laser treatment is usually no longer sufficient. In such cases, surgery is often necessary.
Follow-up and post-treatment care
After retinal laser treatment, follow-up appointments are important to check the treated area. You may experience temporary glare, blurred vision, or mild discomfort.
If you experience new flashes of light, numerous black spots, shadows, a sensation of a curtain falling over your vision, or a noticeable decline in vision, you should see an ophthalmologist immediately.

Common Eye Problems and Conditions
Our eyes are put under a lot of strain every day. Symptoms such as dry, red, or tired eyes, blurred vision, pain, or a sudden decline in vision should be taken seriously and evaluated by an ophthalmologist. Many eye conditions can now be detected early and treated effectively—timely diagnosis is key.
Preventive Care & Eye Exams – Regular Checkups and Early Detection
Regular eye exams help detect changes in the eye at an early stage—often before symptoms become noticeable. Conditions such as glaucoma, age-related macular degeneration, diabetic retinopathy, and cataracts, in particular, often develop gradually.
Poor eyesight
Refractive errors are among the most common reasons for visiting an ophthalmologist. They occur when light is not focused precisely on the retina. Depending on the type of refractive error, vision may be blurry up close, far away, or in both ranges. The most common types include:
- Nearsightedness / Myopia: Clear up close, blurry at a distance
- Farsightedness / Hyperopia: Distance vision is usually better, while near vision is blurry
- Astigmatism: distorted or blurry vision
- Presbyopia: difficulty reading and seeing up close starting around age 40
Refractive errors can usually be corrected effectively with glasses, contact lenses, or other methods.
Dry eyes
Dry eye syndrome is one of the most common eye conditions and is caused by insufficient lubrication of the eye’s surface. Thanks to simple and effective treatment approaches, most patients can find relief quickly. Treating dry eye is an important part of our work, and we always tailor our care to the individual needs of each patient.
Vision problems & sudden vision loss
Vision problems can have many causes—ranging from harmless, temporary issues to serious eye conditions. In particular, a sudden decline in vision should always be evaluated by an ophthalmologist as soon as possible, as prompt treatment is crucial in some cases.
Cataracts
Cataracts, medically known as cataracts, are a natural ageing process that causes the natural lens of the eye to become cloudy. This clouding can impair vision and requires expert assessment and surgical treatment.
Glaucoma
Glaucoma is a serious eye disease that affects the optic nerve. It is often caused by increased intraocular pressure, which can damage the optic nerve over time and lead to loss of vision if left untreated. Early detection and treatment are crucial to prevent potential blindness.
Macular degeneration
Macular degeneration refers to a group of diseases that affect the macula - a crucial area of the retina that is responsible for central vision.
This region allows us to see fine details such as letters when reading, faces, colors and more. The most common form is age-related macular degeneration (AMD), which can occur in dry and wet forms.
In addition, certain factors such as diabetes, circulatory disorders of the retina or severe short-sightedness can increase the risk of macular diseases.
Corneal diseases
Corneal diseases affect the clear front layer of the eye and can significantly impair vision.
Common forms include:
- Keratitis: inflammation of the cornea, often accompanied by redness, pain, and blurred vision
- Keratoconus: Thinning and deformation of the cornea
- Corneal dystrophies: mostly genetically caused opacities
- Changes associated with dry eye: superficial damage caused by insufficient lubrication
- Age-related changes: for example, corneal guttata or Fuchs' endothelial dystrophy
An accurate diagnosis is important for determining the appropriate treatment and preserving vision as much as possible.
Eyelid Disorders
Eyelid disorders include various types of inflammation, deformities, and changes in the eyelids. These include styes, chalazia, blepharitis, contact allergies, drooping eyelids, ptosis, eyelid deformities, and benign or malignant changes in the eyelids.

YAG capsulotomy for posterior capsule opacification
After cataract surgery, vision may gradually deteriorate again. A common cause is what is known as a secondary cataract. This occurs when the posterior lens capsule—which remains in the eye after surgery and helps stabilize the artificial lens—becomes cloudy.
