Vision helps us to admire the beauties, to watch how close people change with age. Without it, it would be difficult to comprehend the basics of science and read your favorite books. A person receives a lot from the visual organ, but forgets that vision also requires attention, at least sometimes. You can conduct an examination of the visual organ using Goldman lenses.
What it is
Before going through any procedure, you should at least learn a little about it and the equipment on which it will be carried out. In this article, you will learn what Goldman lenses are . This apparatus is used to study the fundus, the angle of the anterior chamber, also for stereoscopic observation of them and laser coagulation of their structures.
The apparatus consists of three mirrors, which are rotated at angles of 59, 66 and 73 degrees. This arrangement of mirrors makes it possible to simultaneously examine different areas of the eye, since light is refracted in a special way. Based on this, it can be said that Goldman’s lenses will help to check those corners of the eye that cannot be investigated with other methods.
It is advisable to conduct such examinations:
- people who engage in extreme sports;
- expectant mothers;
- To old people;
- those who have received eye injuries.
What is the procedure for?
Most often, examination of the fundus with a Goldman lens is carried out in combination with other methods of ophthalmology. Only in this case, the doctor will be able to get a complete picture of eye health. During the examination, special drops are used that dilate the pupil. After the examination procedure, you must not drive and engage in work that puts strain on the eyes. When a Goldman lens is used, the examination will be complete. The doctor, using this device, diagnoses the patient’s retina state without any problems, and this must be done before an ophthalmic surgery.
The advantage of this method is the ability to examine in detail the peripheral areas of the fundus and diagnose dystrophic changes and retinal detachment at the initial stage. This is very important for eye health. As soon as you notice a deterioration in vision, constant goosebumps before your eyes, or if after a load on your eyes your head starts to hurt badly, consult a doctor immediately. At the initial stage, many diseases can be cured.
Lens care
Goldman's lenses should be sterilized. For this, a six percent hydrogen peroxide solution is used. The outer surface of the lens is chemically disinfected. To a three percent solution of hydrogen peroxide is added a 0.5% solution of detergent.
The optics are cleaned with a mixture of 85% alcohol and 15% ether. From the surface of the lenses, dust is removed with a fat-free brush. Be sure to ensure that the lenses are not exposed to mechanical and thermal stress.
During operation, the lens must be held by the frame, it is impossible to touch the optical surfaces.
Forbidden:
- Wash lenses with alcohol.
- Rinse with water with a temperature of less than 5 and above 30 ° C.
- Store near heat.
Conclusion
Do not forget that your eyes also require attention. And let them not let you down at the moment, but it’s worth examining them. After all, a disease can hide somewhere inside and manifest unexpectedly.
