Company Profile
Company Profile
CANTOR + NISSEL: LEADERS IN THEIR FIELD
David Cantor founded the original company in 1964 and the Cantor & Silver
partnership was created in 1973 when he incorporated his business with that
of Leslie Silver. A limited company was formed in 1975 and relocated in
Brackley, Northamptonshire.
During the 80s and 90s Cantor & Silver Limited acquired several companies:
Focus Contact Lenses Limited, CLM (Contact Lenses) Limited, Speciality
Contact Lenses Limited and Cambridge Precision Limited.
In August 2000, Cantor & Silver Limited acquired Nissel Limited and changed
its name to Cantor + Nissel Limited to reflect the incorporation of the Nissel
range of products.
Cantor + Nissel Limited is the largest independent contact lens manufacturing
company in Europe and it has distributors in most European countries. The
company exports its finished lenses and artificial eyes widely, with Cantor +
Nissel products being prescribed by eyecare practitioners in over 60 countries
worldwide.
The company has a history of innovation and leading edge product
development; its independence enables it to respond promptly to the specific
needs and expectations of its customers.
Cantor + Nissel Limited is renowned for its comprehensive range of high
quality products and its superb standards of service. The company was
awarded the CE mark in 1996.

Single Use Trial lenses
Single Use Trial Lenses
The 'remote theoretical risk' of transmitting vCJD through contact lenses
created something of a dilemma among practitioners used to relying on
diagnostic lenses in order to assess best fit and prescription for a potential
rigid lens patient. It also created a resistance to prescribe a product that
could not first be tried when tolerance and suitability are so critical.
The Cantor & Nissel initiative to supply single-use trial sets in PMMA to a
practitioner's preferred design has ensured consistency - and even an
upsurge - in the RGP market.
Our free trial set policy means that the busy practitioner can continue to
perform trials as before, but with single-use lenses. These can be promoted
as a benefit - presented to the patient in sterile, sealed, condition and
disposed of after use. Each set is accompanied by a supply of re-order forms
for replacement of the single-use lenses as they are disposed of. Our RGP
lenses all carry the right to up to two free exchanges if required and there is a
75% credit if the patient eventually discontinues. The single-use trial set does,
however, largely remove the risk of eventual incompatibility.
Single-use trial sets are supplied principally in our market-leading Oxyflex 4F
and Metr02 designs ex-stock. They can also be produced for you in the
traditional Percon design or in any design of your choice which we will then
be pleased to reproduce for you for your Rx requirements.

Cantor + Nissel have used their unrivalled expertise in hand painted and
prosthetic contact lenses to develop two outstanding cosmetic lens designs
available in plano and powered forms on a quarterly replacement basis.
New Fabula lenses are a two colour composition based on the results of a
specialist design programme to develop a ‘natural’ iris pattern. This iris
pattern is available in six carefully selected colours.
New Bellina lenses include an additional limbal ring to further improve the
appearance of the lens. This advanced three-colour technique provides
enhanced depth and definition offering greater realism and a natural look.

ChromaGenTM
A range of daily wear soft lenses
designed to improve colour
discrimination
ChromaGenTM
Lens design
Colour blindness is a condition affecting 0.5 per cent of women and eight per
cent of men. The ChromaGenTM lens is tinted to allow the brain to perceive
images differently, enabling the patient to discriminate between colours which
they could not normally ‘see’. Most people need only one lens to help their
colour vision.
Product features
 Can make a big difference to those patients who are colour defective
 Full information pack available; please call for details
 Used to assist patients with ASD (Academic Skills Disorder) such as
dyslexia
Diagnostic sets
A product-specific diagnostic set is essential. Please call professional
Services (Option 2 on the phone menu) for details.

Extreme H2O
A premium monthly disposable lens
range
Extreme H2O
Day long comfort from a lens that will not dry on the eye
The monthly disposable Extreme H2O lens, available through Cantor + Nissel,
is the soft lens of choice for patients who work in demanding environments.
Extreme H2O lenses dehydrate 5 times more slowly than Hema lenses and
rehydrate 5 times more quickly. Extreme H2O lenses are therefore ideal for
patients who suffer from dry eye conditions, have a low blink rate or who work
in air-conditioned or other dry environments.
Benefits of Extreme H2O lenses:
 Day-long comfort
 Will not dry out on the eye
 Particularly suited for computer users
 Should be the first-choice daily wear Hydrogel for patients with dry
eyes

Hand Painted Lenses
High water content lenses, hand
painted to produce colour matches
prosthetic or special effects
Hand Painted Lenses
Fitting and parameters
Any combination of parameters and powers can be manufactured, including
Toric lenses. Lenses can be made up to 22.00mm diameter and can be
stabilised if a non-radially symmetrical effect is required.
Colour details
Photographs, iris buttons, prostheses or artwork can be copied.
Clear pupils
Clear pupils are available in any diameter. Because the opaque is throughout
the thickness of the lens, there may be some glare when very small pupils are
requested (particularly with high plus prescriptions). This may be resolved by
adding a black annulus around the pupil. This may also improve cosmesis.
Black pupils
Occlusive black pupils are available in any diameter. Because the black pupil
is added to the front of the lens, a larger than expected pupil may be required
to get good occlusion. If this is not cosmetically acceptable, it is possible to
paint an opaque ‘patch’ matching the iris around a smaller pupil to achieve
occlusion.
Opaquing
The colours that are used are transparent and on most eyes require a white
salt that is precipitated within the lens matrix to be effective. This is slightly
translucent and the apparent colour of the lens will be affected by the colour
of the eye; the same lens will appear darker on an Aniridic eye than when
worn on a light, scarred cornea. Please indicate the condition of the eye on
which the lens is to be worn.
It is sometimes possible to use lenses with no opaque when fitting totally
white corneas.
Fading colours is not usually a problem with these lenses but there is a small
percentage of patients whose tears may remove the opacity from the lens.
If this happens, the lenses can be re-opaqued for a nominal charge but it is
possible that the problem will recur. A thicker lens may reduce the loss of
opaque material.
20
Hand Painted Lenses
Colour adjustments
Although every attempt is made to be accurate, it is not always possible to
exactly reproduce the required colour. If a lens is not acceptable, it may be
returned and we will attempt to adjust the colour.
‘Offset’ lenses
Strabismus can be masked by using a large stabilised lens with the iris
painted eccentrically and the scleral portion opaqued, coloured and veined.
(A separate information sheet is available on this.)
Special effect lenses
Lenses can be produced for special effects for photography, film and
television.
Reproducibility
Each lens is individually produced and we cannot guarantee exact
duplication. It is possible to create a photographic record of the lens and this
can assist when reordering lenses; a digital image is retained in the studio
and a print is despatched with the finished lens. By using the reference
number included in the print when reordering we are able to access all the
details of the lens. A charge is made for this service which also covers any
subsequent photographs of lens adjustments.
Delivery
Lenses are normally despatched 10-21 days from receipt of order. Lenses
that require special designs may take a little longer. It is sometimes possible
to make lenses more quickly, however these ‘rush’ orders attract a surcharge
of 30%.
Additional information
If you require further information on hand painted or special effect lenses or
an iris identification poster please contact our office or studio.

Hydrofit
A high performance contact lens for
daily wear
Hydrofit
Hydrofit lenses are designed to be the ideal lens for Aphakic and High Myopic
prescriptions as well as being suitable for those patients in every practice who
need a lens that allows them freedom of a flexible wearing schedule. Hydrofit
offers the convenience of daily or flexile wear without compromising corneal
health, visual acuity or comfort. With a minimum thickness profile to
maximise oxygen delivery while remaining viable for handling, Hydrofit should
be the first choice lens for practitioners and hospitals where there is a need to
deliver more oxygen to the cornea.
The lenses are manufactured on computer controlled lathes ensuring
excellent reproducibility. Hydrofit has a wide parameter range offering
practitioners a choice of three diameters to ensure the best possible fitting
characteristics for the individual patient.

Hydrolens
A soft contact lens for daily wear,

Hydrolens
Hydrolens is manufactured to ensure a strong, clear lens which resists
discolouration. Sometimes patients will need soft lenses which are outside
the range of stock parameters; high powers, large or small diameters and
steep or flat base curves.
A graduated aspheric lenticular zone ensures minimum overall thickness in
any power. Every prescription is optimised for handling characteristics and
oxygen transmissibility using a computerised lens design facility. Computer
controlled lathes are used for both back and front surface production to
ensure excellent reproducibility

Nissel Keratoconus II
Soft
3-Monthly soft lenses for
keratoconus, post-cxl and post-graft
corneas
Nissel Keratoconus II soft
The Nissel Keratoconus II Soft lens is designed to fit Keratoconus and
irregular corneas. In most cases, it is expected that the prescription lens will
be a toric so the trial lenses are
presented
with
toric
stabilization.
Manufactured from a 58% water
content GMA material, the
Nissel Keratoconus II Soft
provides
excellent
oxygen
permeability and exceptional
wearing comfort for keratoconus
and post-graft patients. The
front surface is aspheric,
calculated to provide the
clearest possible vision for each
patient.
The fitting system has been
designed so that the on eye
characteristics of the trial lenses
match the prescription lenses as closely as possible.
The Nissel Keratoconus II Soft trial lenses are designed with dynamic
stabilization and have a range of powers to allow diagnostic evaluation with a
power as close as possible to the final prescription. Orientation marks are at
12 and 6 o’clock.
The location of the trial lens mark is important and must be noted when a toric
is ordered, as it affects the axis direction of the final lens.
When ordering, please provide Cantor + Nissel with the following information:
 Base curve (BOZR) and power of trial lens used
 Location of the orientation mark(s)
 Over refraction and back vertex distance
 Horizontal visible iris diameter (HVID)

Nissel Keratoconus II Soft Trial Set
All trial lenses are stabilised using the same design as the likely prescription
lens.
All trial lenses have orientation marks to enable the practitioner to evaluate
the orientation of the lens when it has been stabilised on the eye.
Ideal fitting characteristics
After the lens has been in the eye for a period of 5 to 10 minutes, the
following should be observed in an ideally fitting lens:
 If bubbles form under the lens on insertion, these should settle within 2
to 3 minutes
 There should be vertical movement of approximately 1.00mm after a
blink
 The lens should have fast positive return to the central position after
manual displacement
 The orientation mark should be vertical for an ideal fit
A full fitting guide is available from Cantor + Nissel; for help in individual
cases please contact out Professional Services team.

Pastel Tints
Prescription or stock lenses in 38, 55
and 67 materials available in a range
of eye-flattering cosmetic tints
Pastel Tints
Cosmetic enhancement or colour change
Pastel tints will enhance the colour of light eyes but will have no effect on a
dark coloured iris. They are particularly popular in countries where light
coloured eyes can be made a stunning shade of blue, aquamarine, violet,
green or brown.
Pastel tints can be applied to both iris and pupil areas. It is recommended
that the pupil area is tinted as well as the iris because on occasion a ghost
image may be noticed by the patient when the clear central zone is smaller
than the pupil size. Clear pupils can be supplied if required.
Pastel tints can be combined with an opaque backing in 67% water content
material only to provide cosmetic lenses which will change the colour of an
eye.
A black pupil is also available in 67 material.

Apex Rigid Lenses
Apex rigid gas permeable lenses are
designed to mask trauma to the
cornea
Apex Lenses
Design and material
In cases where a patient may have a scarred or disfigured cornea. Either as
the result of trauma or surgery, an apex lens may be used to bridge the
scarring.
An apex lens is a rigid lens made in a Bicurve design with a very large total
diameter, typically 12.00mm or 12.50mm. Apex lenses will normally have a
back optic zone diameter of 10.00mm.
It has been traditional to produce lenses in clear material although nowadays
many practitioners find that neutral handling tint is beneficial for the patient.
The apex design can be produced in any material. The powers of these
lenses is frequently high plus and it is therefore possible to choose any level
of permeability with confidence.

Aqualine MF Series
The Cantor + Nissel Aqualine MF is a centre-distance simultaneous
Vision rigid lens multifocal.
Progressive power profile
Aqualine MF back surface is a spherical multicurve design with a large optic
zone.
Aqualine MF achieves the right balance between distance,
intermediate and near vision because of its unique aspheric front surface
which generates a progressive power profile that is customised for individual
patient prescription requirements.
Stable vision at distance and near
Aqualine MF provides high quality, stable vision at distance, intermediate and
near. For Presbyopic rigid lens wearers, Aqualine MF is the natural first
choice for clear vision with no compromise.

Bifocal RGP Lenses
A variety of bifocal RGP lenses for
daily wear are made to order
Bifocal RGP Lenses
Segmented bifocal
In this design, a segment is cut using a high precision offset lathe. The result
is a D-shaped segment of reading power which is orientated by means of a
prism to sit inferiorly when worn. Solid segment bifocals are fitted similarly to
a standard lens. A total diameter of 9.40mm is recommended as a first
choice.
Concentric bifocal
Concentric bifocal can be manufactured in any RGP material. The central
zone, typically 3.50mm in diameter, is powered for distance vision. This is
surrounded by an annulus of reading power. The lens-cornea relationship
must be designed to provide on-eye dynamics such that the lens will translate
on downgaze. The lens must be well-centred on forward gaze to make sure
that the patient is looking through the distance zone. Pupil diameters may be
varied to suit individual patient needs.
46
Evolution RGP
Aberration controlled RGP lenses
Evolution RGP
The Cantor + Nissel Evolution RGP employs an advanced aspheric front
surface design to create a lens that can deliver superior quality of vision to all
wearers.
Clearer, sharper vision
Evolution RGP is designed to control both the inherent spherical aberrations
of the lens and the lens-tears-cornea system. As a result, more light is
brought to a retinal focus to give higher contrast sensitivity and improved
image perception especially in low ambient light levels.
Masks astigmatism
The enhanced depth of focus provided by Evolution RGP masks low to
moderate levels of Astigmatism.
Aids the early Presbyope
Similarly, the reduction in blur circle acts as an aid for the early Presbyope.

Keratoconus RGP Lenses
A comprehensive range of rigid
lenses which has been developed
specifically for keratoconus
Keratoconus RGP Lenses
Keratoconus is a corneal ectasia that results in irregular astigmatism.
Although keratometry can provide useful fitting information in the early to
moderate stages, corneal mapping devices are better for interpreting the
corneal topography, especially in the intermediate to later stages of this
disease.
Contact lens fitting in cases of keratoconus can test the skills of the
practitioner. Diagnostic lens evaluation is mandatory. Cantor + Nissel
provide a comprehensive diagnostic set of rigid lenses which have been
developed specifically for this condition
Product features
 Available in any rigid lens material
 Tricurve construction specifically designed for the condition
Diagnostic lenses
Standard sets are available. Please call for details. Currently, the most widely
accepted rigid corneal lens fitting philosophy is one in which the intention is to
distribute the weight of the lens between the cone and the more normal
peripheral cornea. In cases where the cone is well established, this results in
a lens showing an apical contact area of 2-3 mm, an intermediate clearance
zone and a mid-peripheral contact annulus with standard edge clearance at
the periphery. With the exception of very early cases, it is essential to use
lenses such as the set supplied by Cantor + Nissel to achieve this type of fit.

Planned Replacement Programmes
Cantor + Nissel offer a comprehensive range of planned replacement
programmes for soft contact lenses which allow for the frequent, programmed
replacement of lenses at reduced cost. Simplicity and flexibility are the
keynotes; any lens may be covered.
For hospital patients who may damage or spoil their lenses the frequent
programmed replacement of lenses at reduced cost is considered a
particularly attractive financial proposition.
Hospital Plan, Focus Plan and Flexicare in action
 When ordering by post, fax or telephone, confirm that planned
replacement is required and state the frequency of replacement.
Typically lenses may be replaced at monthly or 3-monthly intervals but
any replacement interval can be specified
 When a patient is registered on any of the Planned Replacement
Programmes – Hospital Plan, Focus Plan or Flexicare. A computerised
record is set up
 Cantor+Nissel will confirm the details of the scheme for each patient
along with the first delivery of lenses
 Lenses will then be despatched as required by the frequency of
replacement. Monthly planned replacement lenses are sent in 3 month
packs. For other replacement periods, a new pair is despatched 2
weeks prior to the replacement date
Tinted lenses can be included
Lenses covered by replacement plans can be tinted. A standard additional
charge will be applied for this process.
Cancellation
To cancel or amend the Replacement Plan at any time please quote the
patient’s record number.
Further Information

Scleral lenses
The unique benefits that scleral lenses offer ensure that they maintain a
specialised role in most contact lens practices. Many practitioners opt for
scleral lenses because of their therapeutic and protective benefits. Indications
for scleral lenses include patients who have undergone corneal surgery or
transplants, ocular surface disorders, abnormal corneal topography, tear
retention in severe dry eye as well as protection from abnormal lids and
lashes. Scleral lenses can also be used to manage ptosis by use of ptosis
props.
Haptic cosmetic lenses - shells
These are shells: lenses which cover the whole of the front of the eye and sit
just inside the lids. They can be made in any size, either taken from an
impression or from a fitting shell. Any colouring, diameters and prescriptions
are available with either a clear or a black pupil. The scleral portion can also
be painted or left clear. Any thickness is available from 1.00mm to 3.50mm
(an artificial eye would be made with greater overall substance).
The following can be incorporated into any haptic shell-lens:
 Ptosis
 Shelf/peg/slot
 Black coating on back surface for albinism
 Decentration
 Arcus senilis
 Tinted powered optic
 Fenestrations
 Cylinders
 Oval iris

Hand-painted contact lenses
The highly skilled team of artists assembled at Cantor & Nissel Limited
produce a large range of hand painted scleral and micro-corneal lenses.
Increasingly Cantor & Nissel Limited work from photographs and digital
images. Digital images can be e-mailed directly to the company at
[email protected]. These images are then printed out on a highquality colour balanced printer for the artists to work from. We do recommend
that the JPG format is used whenever possible as this offers the best colour
depth and resolution. Parameters should include base curve, iris diameter,
pupil diameter, whether the pupil should be black or clear, and the power (if
required) in dioptres.
Alternatively, iris matching sets and scleral matching sets can also be used
for colour copying.
In the absence of an image or as supplementary information Cantor & Nissel
Limited also requests the following details:

Colour matching
We offer an exclusive one-to-one colour matching service with our artist.
If a patient wants a perfect colour match we can hand-paint a match of the
‘good’ eye during a visit to our studio at Hemel Hempstead. This takes about
two hours. Once this is completed there is then a permanent record should
the patient ever need a replacement.

Helpful tips
 Always ascertain the patient’s ocular dominance
 Never occlude, as this is a binocular system and the brain needs to
identify the ocular dominance.
 Maximum over-refraction possible for aspheric lenses is 0.50D. Use
hand-held lenses and not a phoropter. The aspheric optical system
used by these contact lenses will not respond to more than 0.50D of
spherical over-refraction. Select another lens if more than 0.50D is
needed.
 For final power selection PV, see tables.
82
The Early Presbyope: EV Lenses
The plus effect inherent in the aspheric optics of the EV38 product will enable
most marginal presbyopes to read at normal reading distances. Simply fitting
the patient for distance with either the EV38 lenses in both eyes will usually
provide the desired amount of addition for near vision and delay the
requirement for a spectacle over-correction. If there is still a slight deficiency
in near vision, the addition of +0.25/+0.50D to the lens in the non-dominant
eye will usually correct the situation without detracting from binocular distance
vision or upsetting distance stereopsis.
Step 1 Use spectacle Rx with usual allowance for BVD where applicable.
Step 2 Transpose cylinder to minus form by adding 25% of the cylinder to
base sphere only to cylinders in excess of
- 0.75D.
Step 3 Allow lenses to settle for about 10 minutes.
Step 4 Check binocular acuity for near without occluding either eye. If
satisfactory, proceed to check distance and correct, if necessary.
 Near additions of up to + I .50D may be corrected by adding +0.50D to
+0.75D to the non- dominant eye without affecting distance stereopsis.
 The addition of +0.25D to the dominant eye will not affect the distance
stereopsis but will provide satisfactory binocular near vision.
83
The Advanced Presbyope
Presbyopic Correction Requiring +1 .25D to +2.75D Addition
The PV Series progressive multifocal contact lenses are ideal for today’s
demanding patients.
Step 1 During the refraction, identify the dominant eye.
Step 2 Select the appropriate lens for the dominant (distance) eye and the
correct lens for the non-dominant (near) eye from the chart, and select the
appropriate lens base curve.
Step 3 After insertion, allow the lenses to 'settle' for 10 minutes.
Step 4 Check binocular acuity for near first, then intermediate and distance in
normal light without occluding either eye.
Step 5 If distance and near binocular acuities are within a line or two of
patient's potential, leave the lenses in for another 45 to 50 minutes to
equilibrate the eyes.
Step 6 If correction is needed, binocularly over-refract the reading (near) eye
first, then the distance eye, without occluding either eye or using a phoropter.
Change lenses if necessary.
 Use spherical equivalent correction, i.e. transpose cylinders into minus
form then add half of the cylinder to the spherical distance correction
before checking the chart.
 Because of the 2.OOD power spread, 0.25D can have unusually positive
effects on acuity.
 When it is difficult to reach a satisfactory balance between distance and
near, try a flatter lens.
 The Emmetropic Patient. If no distance correction is required, all that
may be necessary is to fit the patient with one Cantor + Nissel presbyopic
lens in the non-dominant eye as in Step 2.
84
Optimal Modified Monovision
Front Surface Aberration Controlled Lenses
Standard spherical monovision rarely gives acceptable distance stereopsis
and the need to suppress the non-dominant eye in distance vision is
frequently unacceptable to the patient.
Cantor + Nissel lenses revolutionise the approach to monovision fitting and
optimise the potential for success by exploiting the special characteristics of
aspheric lenses. Simply fit a Cantor + Nissel multifocal lens in the nondominant (near) eye and a single vision aberration controlled lens in the
dominant (distance) eye. The result provides positive stereopsis for both
distance and intermediate vision, leaving the patient monocular only at near,
which is well-accepted by most patients.
Step 1 During refraction, identify the dominant eye.
Step 2 Select appropriate EV38 lens, using spherical equivalent Rx, then
select appropriate lens base curve.
Step 3 From the non-dominant near chart, select a PV Series lens having the
appropriate base curve.
Step 4 Allow lenses to settle for about 10 minutes. Check binocular acuity for
near first, then intermediate and distance in normal room light without
occluding either eye.
Step 5 If correction is required, over-refract, and change lenses if necessary.
 Use spherical equivalent correction by transposing cylinders to minus
form. Add half of the cylinder for the PV lenses. For the EV38, ignore
cylinders up to and including 0.75D, and add 25% to the spherical distance
correction before checking the charts.
 As little as 0.25D can have unusually positive effects on acuity.
 Use flatter lenses if VIDs are large.

Progressive Soft Multifocals
Power Selection and Final Power Form
Nissel PV Lenses
The original centre-near design is specified and labelled with the combined
power form (i.e. Distance Power + Reading Addition). Furthermore the
product name denotes the reading addition, a PV150 having a +1.50D
reading addition, a PV200 having a +2.00D reading addition and so on.
For example, a -1.75D lens with a +2.00D add is specified as a PV200
+0.25D.
Please refer to the detailed fitting charts that follow which provide an easy
reference for the final power forms for both dominant and non-dominant eyes.
