Advanced Technology in Ophthalmology: Essential Devices for Modern Eye Care

Role of Ophthalmologists

Ophthalmologists are medically trained to provide eye care. When we have a vision problem, we approach them, and they should be the first person to advise us on our eye condition. There is a saying that 'a good woodcutter must keep his axe sharp always.' The same applies to eye care, with the axe substituted by advanced high-end technology-equipped devices. These devices are used to perform in-depth analysis of our eyes in case of any eye problem.

Types of Eye Care Devices

The devices are generally divided into two types: basic and advanced. They allow ophthalmologists to track minute changes in the eyes and monitor eye health regularly.

Basic Ophthalmology Instruments

Some examples of basic instruments are the refractor head and biomicroscope.

• Refractor Head: This device measures vision blur in the eyes and provides information on spectacle prescriptions to the ophthalmologist. Nowadays, the refractor head is fully automated, making it very easy for the ophthalmologist to handle. It is also used to compare old prescriptions with new ones. Finally, a computerized record is made with the help of the measurements.
• Biomicroscope: This device magnifies the eyes and is used to detect types of conjunctivitis and cataracts. Sometimes, it is also coupled with advanced lenses to examine the retina, the back part of the eye.

Advanced Instruments

Nowadays, more and more latest technologies are introduced in the market within a short span of time. Some of the advanced instruments are:

• Matrix visual field analyzer
• Visante OCT
• Cirrus OCT
• Corneal topographer
• Rodenstock impressionist
