For this procedure, the doctor will first give anesthetic eye drops. The person will sit with their head resting on the microscope with a slit lamp and the doctor will place a special contact lens directly on the eyeball. The test should reveal any signs of increased eye pressure that may indicate glaucoma. For this purpose, many doctors use a “slit lamp”.
It is a special microscope and light that allow the doctor to see the eyes in 3D, both inside and out. They will use it together with an ophthalmoscope to look at the back of the eye. A slit lamp is a microscope with a bright light that is used during an eye exam. It allows the ophthalmologist to take a closer look at the different structures in the front and inside of the eye.
It is a key tool for determining eye health and detecting eye diseases. The eye doctor may use a microscope called a slit lamp to examine the front of the eye. The microscope focuses a narrow, intense line of light on the eye. The slit lamp provides an enlarged 3D view of the eye and allows the doctor to detect any minor abnormalities.
Used with special lenses placed close to the eye, the slit lamp also provides detailed views of the back of the eye. The slit lamp exam examines structures in the front of the eye. During the exam, the doctor will look through the microscope and adjust the light of the slit lamp to see certain parts of the eyes. In addition, when the slit lamp is attached to a special magnifying lens, the doctor will be able to see the retina and optic nerve located at the back of the eye.
It will then turn on the slit lamp and focus a narrow, high-intensity beam of light toward the eye. The slit lamp is the central instrument of ophthalmology and you'll want to be able to quickly master its use during the first month of your residence.
