Microscopes And The Most Common Ophthalmic Tools
Microscopes have long invaded the fields of medicine and health care. In fact, microscopes are essential tools in certain surgical operations nowadays. There are a lot of operations that have become possible over the years because of the development of operating microscopes. Without them, some diseases would have remained untreatable.
This case is especially true in the field of ophthalmology. By nature, the veins and other components of the eyes are very fine and very small. As a result, it is rather difficult for doctors to carry out certain surgical operations in the eye area. The ophthalmologists of before tend to cure their patients through the usual, indirect way of treatment. Medicines, ointments, and drugs providing relief and cure for patients are given. Surgery of the eyes is unthinkable during the olden times.
But all the reservations and doubts about eye surgery became history when operating microscopes and advanced ophthalmic tools are introduced. These two devices had transformed the then impossible feat of performing surgery on the eyes. Soon enough, eye surgery is not only achieved but is widely used these days.
All modern eye surgical operations are carried out with a power ophthalmic microscope. These microscopes provide images of very high resolution suitable for all types of eye surgery, from a simple operation to a very complicated surgery. The most advanced ophthalmic microscopes today are equipped with features that allow for connectivity to a display monitor, the integration of motorized instruments, and the use of protective eye filters and slit lamps.
Ophthalmic microscopes are essential in cataract surgery, where doctors make small incisions in the eye. Some ophthalmic microscopes especially created for cataract operations are even equipped with a sound wave-producing unit that is used to dissolve the cataract. But aside from cataracts, ophthalmic microscopes are also employed in corneal transplant procedures. This procedure is commonly performed on patients that have scarred corneas. The role of ophthalmic microscope in this particular procedure is to magnify the part that doctors will be treating so that they would have better view of the subject ensuring higher accuracy towards exceptional results.
But the role of ophthalmic microscopes isn’t entirely focused on the treatment of eye diseases. These microscopes are also involved in the diagnosis of diseases. Deeper eye examinations require the use of ophthalmic microscopes. And this is the main reason why these microscopes are indispensable in almost all ophthalmologic functions.
An ophthalmic microscope is a low power microscope that is combined with a slit lamp, which serves as the microscope’s main source of illumination. The light produced by the lamp is rectangular in form. The features and structures of ophthalmic microscopes accommodate the straightforward examination of the cornea of the eyes, its aqueous humor, the retina, and all other essential parts. An ophthalmic microscope is also called a bio-microscope. And inside its system, a keratoscope may be included.
What make ophthalmic microscope unique from all other type of microscope is the presence of lines and circles in the microscope’s field view. These marks are there to examine the curvature of the cornea meridian of the eye. Most ophthalmic microscopes are stereomicroscopes. This indicates that is equipped with either stereoscopic observers or inventers, which main role is to provide a 3D image of the eye’s cornea. The three-dimensional image is achieved by producing the image through high-resolution prisms obtained at varied angles.
Ophthalmic microscopes are created with a binocular eyepiece, as this is the setting perfect for diagnosing eye diseases. The eyepieces can also be tilted or bent for more comfortable viewing. Generally speaking, ophthalmic microscopes are low power microscopes. This means that the magnification power it has is somewhere between 4x to 25x. Ophthalmic microscopes with higher magnification levels are very rare, because the image produced becomes blurred and unrecognizable at higher magnifications. Also, the device itself would obstruct the view of the sample if higher magnification were used. Ophthalmic microscopes commonly use halogen bulbs to produce the necessary illumination. And it is usually mounted very close to the optics so that near-perfect images are produced. The main optical device, however, is commonly mounted to an articulating arm, a boom stand, or any customized system composed of a base stand. The more movable joints the microscope has, the better performance it can provide. There are also ophthalmic microscopes that are fixed to a ceiling or a wall. For such cases, the examination and surgical bed is built in precise position under the microscope.
