[Spherical covering foil--silicone implant forming conjunctival fornices].
METHODS
The authors refer about primary development of elastic and sufficiently strong device, which due to its spherical shape bandages the conjunctival space of the palpebral fissure and is used to form the inferior and superior cul-de-sac. It is made from a silicone mixture for medical use - Silastic Medical Grade Elastomer. Its layer in the shape of spherical cap of outer diameter 24.4 mm, height 8.5 mm; the layer thickness is 0.5 mm. Its advantage is the oxygen permeability.


RESULTS
The spherical covering foil was applied as an arrangement before keratoplasty in four adult men to form fornices after relieving of symblephara reaching the cornea caused by alkali (lime) burn (in three of them) and after liquid aluminium burn (thermal injury). In five years old boy, the spherical covering foil helped to form the palpebral fissure and to improve the eye motility; the symblepharon was related to the inborn coloboma of the upper eyelid. To prevent the symblepharon appearance, the spherical covering foil was used in an adult man after molten polypropylene burn and in an eight years old boy with Stevens - Johnson syndrome.


CONCLUSIONS
The spherical covering foil is used for cul-de-sac forming after relieving of the symblepharon or to prevent its appearance after the eye burn.
