HANS HEISS SLIT LAMPS -ACCESSORIES.

Slit-lamp beam splitter- MAG LENSES - Applanation tonometry 

One of the first individuals to apply microscopy to the living eye was Purkinje, who in the 1820s studied the iris with an adjustable microscope by illuminating the field of view. The uniocular slit lamp was born years later when Louis de Wecker would combine an eyepiece, objective and adjustable condensing lens within a tube. Wecker’s invention was improved upon by Siegfried Czapski, who added binocularity to the microscope. Today, the two main components of the modern slit lamp microscope are the illumination system and observation system. Modern slit lamp microscopes can magnify images between 5X and 25X, with some microscopes allowing magnification to 40X and even 100X. Magnification up to this need to be done by lenses. Usually the ones use with a slit lamp ARE: 20D, 30D, 78D and 90D from HANS HEISS.

TEACHING, OBSERVED AND SHARE

Slit-lamp beam splitter A double binocular beam splitter, compatible with SLIT LAMPS optics, splits the light from each optical train of a slip-lamp microscope to provide an observer the exact stereoscopic view of the examiner. It has advantages in teaching slit-lamp examination techniques. Further, in surgery at the slit lamp, it allows the observer to function as an assistant and the surgeon to have both hands free. Adding slit lamp photography to a practice can offer several advantages in addition to increased practice revenue. The fine detail can allow detection of slight changes of corneal findings, such as resolving corneal infections or edema. For today’s practicing ophthalmologist desiring to add digital photography to their slit lamp examinations, two options are available: custom built in cameras or beam-splitter adapters capable of attaching generic digital cameras or video. The SL9DH | DL-LED ELECTRIC - FOCUS DIGITAL MODULE SLIT LAMP MICROSCOPE – from HANS HEISS-are on the best range ( quality and price) on the market . HANS HEISS have a video box, easy to adapt to any Slit Lamp. Only remove the eyepiece, and put the box on place. No technicians or help to adapt the systems. HANS HEISS sell the beam splitters, separates too, so don’t worry if you only need that part. But remember, if you looking for a dependable, reliable Slit Lamp, come take a look on the http://www.HANSHEISS.com/ Applanation tonometry
A tonometry test measures the pressure inside your eye, which is called intraocular pressure (IOP). This test is used to check for glaucoma, an eye disease that can cause blindness by damaging the nerve in the back of the eye (optic nerve). Tonometry measures IOP by recording the resistance of your cornea to pressure (indentation). Eyedrops to numb the surface of your eye are used with most of the following methods.

Goldman tonometry Goldman tonometry is considered to be the gold standard test and is the most widely accepted method. A special disinfected prism is mounted on the tonometer head and then placed against the cornea. The examiner then uses a cobalt blue filter to view two green semi circles. The force applied to the tonometer head is then adjusted using a dial connected to a variable tension spring until the inner edges of the green semicircles in the viewfinder meet. When an area of 3.06mm has been flattened, the opposing forces of corneal rigidity and the tear film are roughly approximate and cancel each other out allowing the pressure in the eye to be determined from the force applied. Like all non-invasive methods, it is inherently imprecise. The Applanation Tonometer Hans Heiss HAT001, can be mounted on any HANS HEISS slit lamp or any other brands also.
