 | | The increased retention of the device fitted in the upper fornix means the device can be used to deliver drugs to the eyes to treat ailments requiring long term continuous treatment, ie one application for the treatment or prevention of infection or allergy or application every 1 to 3 months or longer for chronic diseases. |
 | | By locating the device within the fornix, the device is imperceptible to the patient, through restriction of the device to a specific size range and shape, with the upper limit not being governed by the geometric space limitation of the whole eye, and by placement specifically within the fornix, not simply within the conjunctival cul-de-sac. |
 | | The insert device of the present invention must be positioned precisely and remain anchored in the upper or lower fornix, known also as the superior conjunctival fornix or the inferior conjunctival fornix, as distinct from the positioning of other kinds of devices anywhere in the conjunctival cul-de-sac. |
