The perforated tray was checked in patient's eye socket and adjusted accordingly. A syringe without the needle portion was attached to the centre of impression tray to serve as a handle for the tray which also served to inject the impression material into the defect area to record the intra-orbital topography (Fig. 2A). The impression of the right eye was made with thin mix of ophthalmic grade alginate (Opthalmicmoldite, Milton Roy Co. Ltd., Mumbai, India) cast was poured (Fig. 2B, C).
