Application of lasers in ophthalmology

Performing laser photocoagulation on a biomicroscope

Laser photocoagulation is one of the basic forms of therapy when it comes to diseases of the posterior segment of the eye, whether they are vascular or degenerative diseases.

In vascular diseases, we most often use laser photocoagulation in the treatment of diabetic retinopathy.

In diabetic macular edema, focal-grid laser photocoagulation is applied, which is usually performed in one act, the application of the laser seal is painless, very good cooperation between the patient and the ophthalmologist is necessary, because the question is a very precise intervention.

In proliferative diabetic retinopathy, panretinal laser photocoagulation is used when it is necessary to cover all four quadrants of the retina with laser seals, so that the patient is usually scheduled to intervene in 4 sequels with intervals of 1-2 weeks. In this way, we destroy the ischemic zones of the retina that have remained without circulation and sample, through VEGF factor, the growth of pathological blood vessels. Pathological blood vessels are the basis for numerous bleedings that endanger the patient’s vision and represent a major problem for further course and treatment. Panretinal – PRP treatment is applied after central retinal venous thrombosis, which also belongs to the group of ischemic retinal diseases.

Vitra 2: Quantel Medical 532 nm green photocoagulator

Recently, these laser treatments have been used in combination with the application of antibodies to VEGF growth factor in the form of intravitreal injections. This achieves stabilization in a shorter time, and provides patients with better visual acuity.

Peripheral changes on the retina in the form of ruptures and degenerations are also treated with laser photocoagulation, thus preventing retinal detachment.

Dr. Sandra Jovanović’s office is proud to present the Vitra 2 Quantel Medical device for retinal laser photocoagulation 532 nm – green spectrum. It can be applied in the form of single laser spots – single spot or multisport mode. It belongs to a new generation of lasers with increased power levels. It can be adapted for work on a biomicroscope, through indirect ophthalmoscopy in the form of indirect laser treatment, as well as for work in the operating room with special accessories.
