Summary This study was undertaken to confirm that Panasil light body is a suitable replacement impression material for Panasil ‘C’, used for ocular impression procedures, which was withdrawn by the manufacturers in 1993. The damaging effects to the corneal and conjunctival tissues of alginate materials used in the past during impression‐taking procedures for artificial eye and cosmetic shell prostheses, is recognized by ocularists and optometrists. Modern silicone impression materials demonstrate: 1. Minimal disruption to tissues. 2. High accuracy. 3. High strength in relation to thin section. 4. Good flow characteristics prior to curing. Panasil light body impression material is polyvinyl siloxane based, low viscosity, addition curing silicone. Our trial investigated the effects of obtaining impressions from five groups of patients presenting with: 1. Anophthalmia with hydroxyapatite implants. 2. Phthisical eyes. 3. Unsighted vascularized eyes. 4. Clear corneas. 5. Exenterated orbits with osseointegrated implants. Total number of patients examined was 30. In all cases where an eye was present, post‐procedural examination by Burton/slit‐lamp with fluorescein was carried out to determine the level of tissue damage/abrasion. A table of results is presented. We have shown that Panasil light body silicone impression material is accurate and stable when used for the purposes investigated. We would emphasize the minimal adverse effects to the corneal and conjunctival tissues observed during the course of this study.
