Sample interview questions: Can you explain the concept of laser-induced thermal therapy and its significance in ophthalmology?
Sample answer:
Laser-induced thermal therapy (LITT) is a minimally invasive technique that utilizes laser energy to precisely and selectively target and destroy diseased tissue, while minimizing damage to surrounding healthy tissue. LITT has gained significant importance in ophthalmology, offering a less invasive and more precise alternative to traditional surgical approaches for treating a variety of conditions. Here are the fundamental concepts and significance of LITT in ophthalmology:
Principle of LITT:
LITT involves the use of a laser system to deliver a highly focused beam of light energy onto the targeted tissue. The laser energy is absorbed by the tissue, leading to a rapid temperature increase and localized tissue destruction due to thermal damage. This thermal effect is precisely controlled to achieve the desired therapeutic outcome, while avoiding collateral damage to surrounding healthy structures.
Applications in Ophthalmology:
LITT has been successfully employed in ophthalmology for the treatment of various conditions, including:
-
Glaucoma: LITT can be used to create precise and controlled drainage pathways in the eye, reducing intraocular pressure and alleviating symptoms of glaucoma.
-
Retinal Disorders: LITT enables the targeted treatment of retinal diseases, such as diabetic retinopathy and age-related macular degeneration, by selectively ablating abnormal blood vessels or damaged tissue.
-
Cataracts: LITT offers a non-invasive approach for cataract removal, employing short pulses of laser energy to vaporize and emulsify the cataractous lens, which can then be removed through aspirati… Read full answer
