More than 10 years before the founding of today’s SwissLens company, contact lenses were already manufactured using the in-house lathes at the site in Prilly, near Lausanne and sold regionally. It was during this period that the various patents originated which SwissLens still uses today for the production and stabilisation of soft contact lenses.
The courage to expand under the new name of SwissLens 20 years ago and to become established outside of Switzerland has paid off. Over the years, the four-person business became a medium-sized company which exports its products to 18 countries and has more than 3000 customers and distributors.
The courage to expand under the new name of SwissLens 20 years ago and to become established outside of Switzerland paid off. Over the years, the four-person business became a medium-sized company that exports its products to 18 countries and has more than 3000 customers and distributors.
It is essential for sustainable company growth to always remain true to one’s core values but also respond to changes in the market and as such, we were amongst the first manufacturers to move to 3-monthly replacement lenses from lenses which were only replaced annually or even less frequently. Stability and solid growth are important elements of our company’s philosophy, as are the aspiration for technological innovation and an active interest in trends within the contact lens industry.
Today, SwissLens has an impressive portfolio of specialist lenses including soft lenses for keratoconus and post-operative patients, hybrid lenses and a range of prosthetic, cosmetic and contrast-enhancing filter lenses. Soft contact lenses to slow the progression of myopia were introduced in 2010 and more recently, ortho-k contact lenses are now being made.
Customer satisfaction and user friendliness have been at the heart of developing the order and return system, together with an on-line toolbox to aid the practitioner with lens parameter selection.
Many of the employees at the Swiss headquarters and at the various international distributors have been working for SwissLens for many years and a community has developed like a large family which bears the success of the company.
In 2009, the Swiss Opticians Association conducted a survey to find out the state of development in the Swiss Optical market. After a long period of gaining acceptance, contact lenses are experiencing a boom in the Swiss market. A substantial 14% of Swiss are currently wearing contact lenses. This means that around 21% of ametropic people here are using contact lenses. Especially younger people are favoring contact lenses to wearing glasses. The market for custom-made contact lenses is declining year-on-year, however. This means that standard disposable contact lenses are gaining share and are poised to overtake the market. The optician still has a major influence on this market. However, this dominance is coming under pressure from an internet-influenced market.
Under these circumstances, does the promoting of disposable, over-the-counter contact lenses make sense? This publication will attempt to answer this question.
A study conducted in 2009 compares spherical silicon hydrogel contact lenses, which were placed in healthy eyes. This study tested a custom-made silicon hydrogel lens against an over-the-counter disposable SIH. The aim of these tests was to find out which of these two products best adapted themselves to the naked eye and, most importantly, left no indentation effect on the conjunctiva, and that the DK-value of the material was high enough (at least Dk/t 24 according to Holden&Mertz) for daily usage. For the author, the comfort of the soft lenses for the test subjects was also a priority. Among the custom-made SIH lenses, the Orbis Definitive (Swisslens) beat the Air Optik Individual (Ciba Vision), as the Modulus MPa proved to be much lower. Regarding the disposable lenses, Biofinity proved to be clearly superior to Air Optix Aqua (Ciba Vision), Air Optix Night & Day (Ciba Vision) as well as Pure Vision (Bausch & Lomb) in the MPa tests.
As this study was conducted on “spherical eyes”, the subjects were chosen strictly according to this criteria. The average K-reading was 7.63mm in both eyes. The average corneal diameter was 11.4 in the left eye, and 11.5mm in the right. The average age of the test subjects was 29 years old. The BUT-Test found that 14% of the subjects were under 5 seconds, and 79% was 5-10 seconds; 7% of the subjects were under 10 seconds.
Test subjects wore the Orbis Definitive and the Biofinity lenses in their right and left eyes respectively. The test subjects were not aware which lenses they were wearing in which eye. Hence, this was conducted as a “blind study” of contact lenses.
After insertion of the lenses, the first check-up and subjective comfort tests were conducted. After 5 hours, a follow-up was made. Afterwards, the test subjects were given lenses, which they could wear over a period of 3 – 4 weeks. The final follow-up was the most comprehensive conducted. The subjects
were asked to respond to questions regarding comfort, and how many hours of wearing. The specialist
then evaluated the alignment and movement of the contact lens, the moistening of the surface, as well
as any alterations or indentation to the conjunctiva with the help of fluorescein.
The study found that the comfort of the Biofinity lens decreased over the course of testing. Despite the
fact that 86% of test subjects found the Biofinity lens to be “very comfortable” initially, only 64%
reported the lenses to still fit comfortably at the end of the test phase.
The Orbis Definitive fared better overall during the test phase, compared to the Biofinity product – 36%
of the testers found the contact lens to be “very comfortable at the end of testing, and another 36%
reported that the lens sat comfortably in the eye.
The optimal movement of the Biofinity contact lenses was reported to over time to have decreased,
from 93% initially to 86%. The optimal movement of the Orbis Definitive increased from the initial 86%
to nearly 100%.
In follow-up analyses, the Orbis Definitive shows significantly less contact lens-induced indentation, or
staining. None of the custom-made SIH lens left indentation or staining. To be noted: 50% of Biofinity
test subjects were not affected by indentation. The other 50% reported slight-to-strong indentation.
One of the main questions posed as a result of this blind study is why the Biofinity was consistently
superior to the Orbis Definitive in the comfort tests, however the Orbis Definitive was better when it
came to indentation. Despite the fact that the Biofinity lens consistently decreased in comfort, it was
still better liked in general that the Orbis Definitive. The reason for this could be because the centerthickness
of the Biofinity is much thinner (-3dpt: 0.08mm) compared to the custom-made lens (-3dpt:
0.12mm). Also, the approach of fitting the lenses is different. The custom-made contact lenses are fitted
to be more “flatter and more moveable” as opposed to the silicon disposable lens. One of the main
reasons for this superior comfort is the edge profile of the Biofinity lens. The tighter-fitting Biofinity
lenses were initially more comfortable.
The inferior tear exchange is not normally noticed by the contact lens wearer. The modulus was also not
a major factor, however the modulus of the Orbis Definitive (Mpa=0.39) was markedly inferior to the
modulus of the Biofinity product (Mpa=0.75). The “Comfilcon A” material used to produce the Biofinity
lens is also stiffer than the Orbis Definitive.
The results of the indentation speak for themselves. Here, the Orbis Definitive is unbeatable. In the final
checkup, there was absolutely no indentation to be found. A finding which is directly linked to the high
quality of the materials, to the customized parameters, and also to the edge profile of the lens. The
Biofinity lens already showed staining due to indentation among 50% of the subjects during the first day.
As the correlation between the indentation and comfort could not be understood in the test phase, the
profile of the edge needed to be further investigated.
In order to better comprehend the differences in results regarding comfort and indentation, a study was
conducted by Mrs. T. Hübner (FH Jena). She studied the fitting criteria of disposable lenses with regard
to their edge profile. In her conclusion, she wrote that the fitting and comfort will influenced by the
edge profile, depending on the lens material and design. Lenses with sharper edges should avoid high
As can be seen in the microscopic photographs below, the edge profiles of both lenses are clearly
different. It is clear that the edge profile of the Orbis Definitive is much rounder and smoother than that
of the Biofinity, which has a much sharper, thinner profile.
As Mrs. Hübner found in her studies, the sharper lens profile is initially more comfortable, whereas the
rounder edges are physiologically acceptable for the long term.
Contrary to most documentation on Silicon Hydrogel Contact Lenses, this blind study has not only taken
into account the pure “Dk-value” of soft contact lenses, but has also analyzed the fitting performance
and above all the edge profile of these lenses. Generally, custom-made lenses should be favored.
Despite the fact that the Biofinity lenses was clearly superior with regard to comfort, the Orbis Definitive
was unbeatable when it came to preventing the staining of the sclera and for long-term wear.

Carried out by an external laboratory, the DK value measurements of HydroColor and HydroColor Pro colour lens have revealed that the colour did NOT impact the oxygen permeability in any way. The uncoloured material (Contaflex 67%), as well as the coloured lens shows the same DK value. The same applies to the prosthetic HydroColor Pro with its opaque layer.
Thus, the lenses along with a high water content material as well as a thin lens design without sandwich configuration, provides the users a high physiological comfort.
