A slit lamp is one of the most effective ophthalmological instruments, a high-intensity source of light used for eye treatment. The doctors focus it on a thin, light sheet and then into the eyes. The eye specialist will use it to examine the interior of the eyes, including the cornea. You can purchase this equipment from reputable medical equipment stores for the best quality slit lamp in India.
The Slit Lamp: An Ophthalmic Equipment
The ophthalmologist will use this tool to determine eye health and detect eye diseases, if there are any. It helps with accurate eye diagnosis after careful examination. Recent developments have led to its extensive usage by optical physicists. Therefore, it has become a staple object of need for contact lens opticians.
The Goldmann or Volk lenses are suitable for inspecting the eye interiors like the posterior section, the retina and the vitreous. With the slit lamp, you can closely examine the front portion of the eyes, also the an6terior segment, especially known as the cornea.
Therefore, the slit lamp aids with the medical examination of the following eye parts –
- The sclera
- The cornea
- Back of the eye like optic nerve and retina
Essential Features of a High-Quality Slit Lamp
The slit lamps have two types of illumination – “Zeiss” or the integrated illumination type and the tower type illumination, also called “Haag Streit”. In the Haag Streit style, you get the light source from the top portion of the instrument. In the Zeiss style, the light source supply is from the base. The practitioner and ophthalmologist will prefer the instrument type as per their preference. The illumination techniques vary, like diffuse/direct, retro, focal slit illumination, focal broad beam, specular reflection, sclerotic scatter, etc. This is to view the eye structure and the tissues.
2. Width/ Length
It deals with the adjustment feature of the slit lamp. Similar to the power of magnification, you can adjust the slit length and width for different stages of eye observation. In Van Herick’s technique, you require a 60° slit to measure the anterior chamber angle and 6x-10x magnification into the limbus.
3. Magnification Power
A slit lamp with high magnifying power is highly essential. You require at least 20X magnification for a brilliant performance of the equipment. The ophthalmologists like to begin the eye examination with a larger view and then adjust it at special interest areas.
4. Light source
Modern varieties of the slit lamp come with LED light bulbs and other halogen source options for illumination. LED lights offer a cool view of the retina, making it easy for the doctor to observe. The slit lamps do not come with a heated light, or else the patient will feel uncomfortable.
