Abstract
Still widely used in RD surgery (SB), the proper cryo technique requires much more attention and expertise than is commonly understood. A useful weapon when appropriately employed, cryopexy can be dangerous when it is applied at the wrong location or at too high a power. Conversely, its destructive force can be utilized in eyes with high IOP, peripheral retinal neovascularization or ischemia, or vasoproliferative conditions.

Notes
- 1.
Most of what is discussed here relates to RD surgery.
- 2.
Unlike with laser, which typically involves only the external retinal layers (see Chap. 30).
- 3.
Some older models have a freezing effect along the shaft, not only at their tip (see the comment about the scleral depressor under Sect. 28.6): the area affected by the freezing is larger than intended.
- 4.
Significant and potentially painful lid swelling develops postoperatively if the lid has been caught.
- 5.
That is, PVR risk.
- 6.
The duration indicated below is therefore only a rough estimate.
