Endoscopic cyclophotocoagulation using iris hooks versus viscoelastic devices.

Endoscopic cyclophotocoagulation utilizes a diode laser to ablate ciliary body epithelium, resulting in decreased intraocular pressure. Viscoelastic devices are often used to elevate the iris for improved exposure and efficient treatment of targeted tissue. Occasionally, early postoperative intraocular pressure spikes may occur due to retained viscoelastic material. Iris hooks may provide a safe alternative for elevation of the iris during endoscopic cyclophotocoagulation treatment and may be particularly advantageous in cases of aphakia or posterior capsule compromise in which viscoelastic removal is made more difficult.
