Artificial eyes | Scleral lenses | Corneal lenses

Stock artificial eyes
These can be supplied singly from the size chart in any colour from the range of 72.

They are also available in sets of 24, comprising 12 right and 12 left, presented in a carrying case. We usually supply a range of colours to customers' indigenous requirements although any colours are available from the 72-sample range together with a variety of appropriate scleral shades and veining structures.
These sets have the advantage of dual usage: they serve as a very good fitting set and also an excellent colour-matching set.
Stock conformers - We supply these in the same way as the stock artificial eyes but in blank form: usually white with the same sizing and set format.
Loan sets - We operate a loan system of fitting sets and colour matching buttons and impressions.
Goods are charged at full price and then credited less a handling fee on their return.

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

These are used for correction or as a fitting aid for future prosthetics.
There are three types:

• Moulded which is moulded to the cast supplied from an impression or an existing shell lens
• Wide angle which is fitted from our standard 24-lens trial set
• Spherical which is fitted from our standard 8-lens set

The shell-lenses can be of any dimensions and any thickness from 0.80mm upwards. The following can be incorporated onto any lens-shell:

• ptosis
• prop/peg/slot
• tear channel fenestrations
• tinted optic
• build-ups
• cylinders

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 info@cantor-nissel.co.uk. These images are then printed out on a high-quality 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.

Micro-corneal cosmetic lenses in PMMA

Micro-corneal cosmetic lenses in PMMA with clear or black pupil can be manufactured to any prescription

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.
