Gelatin implants in scleral buckling procedures.

In 375 scleral buckling procedures, an absorbable gelatin implant (Retina Gelfilm) was used. This series included 192 trapdoor and scleral pouch procedures, and 183 operations in which a gelatin implant was used beneath a silicone rubber implant. Two thicknesses of gelatin implants were used, 0.5 mm and 0.75 mm. Absorption time varied from 2 to 24 months, depending on the thickness of the implant and whether it was used alone or beneath a silicone rubber implant. Gelatin is an excellent absorbable implant when used alone or under a silicone rubber implant in selected patients with retinal detachment to produce a temporary elevation or posterior extension of the buckle, or both.
