Summary

No single type of laser or set of laser parameters is appropriate for all type of irides. Pure Nd:YAG laser iridotomy is very effective in the light color irides. It was considered as the gold standard for iridotomy. It, however, is less effective and causes some complication such as iris hemorrhage especially in patients with dark iris.

Conditions

  • Angle Closure Glaucoma

Interventions

DEVICE

The sequential technique

By using 'the double frequency YAG laser' to make the initial bore and 'the Nd:YAG laser' to complete the perforation on iris.

DEVICE

The pure Nd:YAG laser technique

By using 'the pure Nd:YAG laser' to make a complete perforation on iris.
