Volk and Ocular lenses

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 
  • Lens 
  • The cornea 
  • Back of the eye like optic nerve and retina

Essential Features of a High-Quality Slit Lamp

   1. Illumination  

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.

As it comes to buying ophthalmic instruments, price is not the only thing to consider. Reliability, quality, warranty, services, after-sales support, reputation are the other things you need to look for. Such equipment is a valuable investment for eye specialists and optometrists. Unless the devices work properly, the health of the practice of the professionals will be affected. However, getting the right equipment need a bit of research. You need to check some important factors to ensure buying the right thing. 

Things to Consider before Choosing Ophthalmic Instruments

Before you buy any ophthalmic instrument, have a look at the following factors. 

1. New or used product

New products are available with a warranty. Also, the company manufacturing the products will be there to help you with any difficulties faced while operating the equipment. On the other hand, used Ophthalmic instruments in Kolkata don’t have such supports. But they ensure high monetary rewards. While buying new items, shop around not only for the price but also for the company’s reputation. You may ask your peers for references. In the case of used products, the seller should have a well-documented history of service regarding proper maintenance of the product all through his/her ownership. Many online portals sell used ophthalmic equipment with standard documentation, proper return policy, and limited warranty. Look for such items and reduce the burden of risky buying.

 2. Service and warranty

In case of a large purchase, a warranty is the most important thing to consider. Maintaining the health of the devices is vital. This is the key to make the investments last. Warranties from upstanding companies are more valued than ones from relatively less-known suppliers. Ask yourself a few questions before making a buying decision.

  • Is the seller reputable?
  • Does the company have an exclusive service department?
  • Do they accept on-site calls?
  • What warranty does the company provide?
  • Which items are covered under the warranty?
  • What is the duration of the warranty?
  • Does the company have its own repair cell or depend on a third party?
  • What is its return policy?

3. Pricing

Buying Ophthalmic instruments in Kolkata is a serious and expensive decision. You should have a clear idea about the return on investment over time. If a dated model of the equipment can perform essential functions, you can save a lot by buying that used item. However, the safety and security of the new items under warranty are worth the additional costs. Price definitely matters. Nevertheless, this shouldn’t be the only factor to consider while making such an important decision of buying ophthalmic equipment.

There are many factors that you must consider while making a large purchase for your practice. And ophthalmic instruments are one of the most important of them.
