Irisotomy

Particularly suitable for cases with a tendency to iris bleeding. Iridotomy considerations: 1. Apply viscoelastic agent to maintain the depth of the anterior chamber and limit bleeding. 2. When there is a transparent lens, first inject viscoelastic agent into the posterior chamber and deepen the posterior chamber before operation, so as not to damage the lens. 3. Radial total iris resections will expose the suspensory ligament below. Cataract surgery should be avoided from here. So as not to damage the ligament. 4. For non-phakic eye surgery, a second peripheral iris resection should be performed to prevent vitreous pupil block, and anterior vitrectomy should be performed if possible. 5. Those who have adhesions should be separated first, and then cut in order to ensure the integrity of the iris. 6. Postoperative treatment is the same as iris resection.
