If you try to check over the internet and even in local brick and mortar shops, you will notice that there are a wide range of surgical loupes options to choose from. Each of the available brands and models is unique from each other. Given your unique needs, we can safely say that not all of these brands and models will fit you perfectly.
There are a few important factors to consider when choosing a new pair of dental surgical loupes. One of these critical factors is the magnification power. Below is a guide on how to correctly choose the right magnification level for your new loupes.
How do you choose magnification power?
Dental loupes are available in different magnification powers- ranging from 2.0x to 6.0x. Each of these magnification powers or levels has its own uses and applications.
Choosing the magnification power is based on personal preference. However, you must not think only of your preferences but also try to consider the general guideline as this will guide you towards picking the right magnification level that will perfectly fit your needs.
For dental applications:
Those who intend to use the loupes for dental applications like implantology, general dentistry, routine surgical procedures on bone or soft tissue, tooth preparations on typical, normal-sized teeth and evaluating dental hygiene patient, you can choose a pair with a 2.5x, 3.0x, or 3.5x magnification power.
For dental procedures that require better precision like when doing bridge and endo/crown works, you may need to get a loupe with higher magnification power, preferably 3.5x, 4.0x, or 4.5x.
These magnification levels are also ideal for procedures involving very small teeth and very small scope. Higher magnification power is also required for extremely delicate procedures like evaluating fixed prosthesis, apicoectomy, and other procedures that require more precise hand movements.
The best magnification levels for dental lab work are between 4.0x and 6.0x. This range is also ideal for dental technicians.
For students and dental hygienists:
For dental students and dental hygienists, a 2.5x magnification power is sufficient enough.
For surgical applications:
Surgeons who are going to use the surgical loupes in procedures like minor plastic surgery, vascular, and cardiac operations, shall choose a magnification power between 2.5x and 3.5x. This range is also applicable for most microsurgical procedures.
If you are planning to use the loupes for more detailed surgical operations like nerve, tendon and digital vessel repair, you may need to opt for a pair of surgical loupes with higher magnification levels. In most cases, 4.5x, 5.0x, and 5.5x are enough to provide you with a larger, more precise image of the operating field.
6+ Magnification power
This level is typically used in more complicated operations that require higher levels of precision. Most of the users looking for loupes with 6.0x or more magnification power are those who have been used to using higher magnification optical instruments like a microscope.
Please note, though, that this is only a general guideline and may also be applicable only to individuals with an average-sized person.
If you are taller than an average-size person, you may need to opt for at least a level higher than recommended. Whether you are sitting or standing, you will naturally be staying farther from the operating site than the average-sized person. This means that your visual access to the operating site is reduced. Opting for higher magnification is usually enough to fix this small difference in distance.
* If you are new to surgical loupes, it is recommended that you start with the lowest available magnification powers (preferably 2.5x) as they are easier to adjust to and use. This is because lower magnification loupes offer a larger field of view.
* Once you have already got used to working with loupes, you can then opt to upgrade to higher magnification power. That is if your work requires higher magnification and better precision. However, if not, you can get well with just the minimum power.
* Please note that the higher the magnification power is, the more the field of view is reduced. So this goes without saying that, lower magnification loupes have a wider field of view than those with higher magnification powers.
* Upgrade to higher magnification loupes only if you have been working with loupes for a long time and your eyes are already used to working with larger images and smaller field of view.
* Some surgeons and dental clinician say that the higher magnification, the better as it provides greater detail of the viewing field. However, this is not always true. The process of learning to work with a magnified image can be rough and lengthy when you jump into higher levels directly. If you really have to get higher magnification loupes like for instance 5.5x, at least, try to start with a level lower than 5.5x. This will not only make it easier for you to adjust to working with a magnified image, but it will also save you from health problems like eyestrain or fatigue and headache.
Why is it important to pick the right magnification?
The magnification loupes can either break or make you. If you have picked and used the right magnification for the procedure you are doing, you can be able to gain the many benefits loupes offer.
On the other end, using the wrong magnification can negatively affect your work. For instance, if you are using a 5.0x loupes for general dentistry which requires only a minimal magnification, then you may experience image distortion or you may miss some areas because your field of view is quite limited. It would take a lot of time and effort to evaluate the oral cavity as you can only one small area at a time.
Unlike the surgical operating microscopes, the surgical optical loupes come only with a single magnification power. It does not have a couple of different magnification options available within one instrument. Once you decide on a certain magnification level, you will need to stick to it unless you buy a new pair of loupes. You can’t adjust the level anytime you want or need by your own as you do with surgical operating microscopes. Not to mention, the cost of a new loupe is significant. That is why you need to make sure that the one that you choose best fit both your preferences and needs.
