The Berghaus/Schrom lid chain is an implant to restore
dynamic closure of the eye in cases of Lagophthalmus,
resulting from facial paralysis. The implants have the design
of a chain to smoothy adapt to the form of the tarsus.
The pre-drilled holes are for easier fixation.
Using platinum and iridium has many advantages
over the commonly used gold implants, particularly
when considering weight distribution and biocompatibility.
The combination of the materials and the chain form
is reflected in the above-average results and lower rate
of complications.
Advantages of the lid chain
- Flexible
- Very good tissue compatibility
- Increased density (volume reduction > 10%)
- Optimal pretarsal placement
- Reduction in post-operative complications
- Excellent cosmetic results, high patient satisfaction and quality of life
- Complete closure of the eyelid
- Completely reversible without complications
- No restriction of the peripheral vision with binocular eyesight
- Can be combined with other surgical eyelid corrective procedures

Different weights are offered from 0.6 g to 2.0 g in 0.2 g increments. The appropriate weight is determined by preoperative fitting. For this purpose, test weights are used, which are glued to the upper lid to determine a sufficient lid closure.
