These two photographs show a spectacle mounted facial prosthesis. Spectacles are dispensed using a frame with a wide enough metal insert in the side to allow pinning of the temporal support. The prosthesis is hand made by the Ocularists in the Ocular Prosthetics department here at Moorfields Eye Hospital. Please click on images for larger view. Sprung sided frames cannot be used.

                       

These shots show a +30.00 dioptre high add (+5.00) lenticular bifocal pair of spectacles.

                       

This patient required +10.50 R & L for near vision plus 24 dioptres of base in prism. She had previously worn spectacles with a fresnel prism attached as was not aware of any other option. Glazed with 1.6 index material with 12.00 BI each eye. Necessary to ensure pads could be splayed suficiently to be comfortable in wear. Patient happy with the results because, although thick and reasonably heavy, clarity of vision was much improved without the need for the fresnel prism. Click for larger view.

                

These images show a left lens of prescription -16.50 +12.00 x 65 produced in a biconcave lenticular in a 1.67 index material. The patient had previously worn biconcave full aperture lenses but had issues with weight and thickness - very happy with this result. Although field of view is compromised somewhat and the lenticulated surface results in an oblique oval - due to axis direction, the result gives a much improved cosmetic appearance. Click to enlarge. Lenses supplied by Lentoid Optical.

                                          

 These are 'Lundi Loop' ptosis props fitted for a patient with an alternating ptosis. Note clips on top rim to allow prop to be 'parked' when not in use. 

               

These are a simplified ptosis props produced with nylon cord with enough resistance to hold eyelids in place. They can be produced on site with a little training. Measurements need to be taken for length, let back and angle of contact with the lids. they can be provided for one eye if a pair not required. These give a more acceptable cosmetic appearance and are generally quite well hidden by the top rim of the frame. As with Lundi Loops the patient needs a little instruction in their use. They can only be fitted to plastic frames with a thick enough rim to allow drilling without reducing the strength of the frame.

                          

Example of a hand made frame for a child with severe facial deformity. This was the first pair of spectacles worn by this child who unfortunately gave little response at the time of taking measurements, however was very responsive to surroundings once spectacles were worn.
