Laser therapy is an out-patient procedure used to treat a variety of disorders. It is classified into 2 types: hot laser and cold laser (photodynamic therapy).
However, because a photosensitive dye is injected into the body, exposure to bright lights (including sunlight and halogen lamps) should be avoided for a few days following the laser eye surgery treatment.
Hot Laser Therapy
In the treatment of diabetic retinopathy and some kinds of wet age-related macular degeneration/polypoidal choroidal vasculopathy, heat is utilised to burn and eliminate aberrant regions of the retina. Hot laser therapy is also used to intentionally cause scarring in certain parts of the retina in order to close retinal tears and avoid retinal detachments.
The Pascal system is an automated laser delivery system that is significantly faster than traditional lasers while causing less pain and negative effects.
Cold Laser Therapy
Cold laser therapy is also known as photodynamic therapy. It is utilised when hot laser therapy is not appropriate, such as when the condition is located at the macula and using the hot laser might compromise vision.
Photodynamic therapy employs a photosensitive dye to treat macula diseases while sparing normal tissue using cold laser therapy.. This technique is performed as an out-patient procedure. However, because a photosensitive dye is injected into the body, exposure to bright lights (including sunlight and halogen lamps) should be avoided for a few days following the treatment.
