The lasers presently used in ophthalmology are listed in the table.. We can distinguish among five different kinds of tissue change caused by lasers: photocoagulation, photovaporization, photodisruption, photodynamic effect, and photo-ablation.. Photocoagulation therapy is used in vascular diseases of the retina, particularly diabetic retinopathy ..

Lasers (surgery) by Christina Y.. Weng, MD, MBA on May 31, 2022.. Laser is an abbreviation for (Light Amplification by Stimulated Emission of Radiation).. The concept of ocular therapy using light was published first by Meyer-Schwickerath, who used the sunlight to treat patients with ocular melanoma in 1949..
Lasers in ophthalmology – this image was taken of a human retina was taken using optical coherence tomography (OCT).. OCT takes advantage of the coherent light produced by lasers in order to image and help diagnose a variety of conditions.. Picture courtesy of the American Academy of Ophthalmology.. The imaging techniques behind OCT is very ..
Photocoagulation treatment uses a laser to shrink and eliminate the ends of any damaged blood vessels, preventing further damage and vision loss.. These are just three of the most common uses of lasers in ophthalmology.. We often employ laser technology to treat glaucoma, posterior capsule opacification, diabetic macular edema, and more..
