1. Normal life and living should be maintained to avoid complications due to agitation. For example, patients with diabetes should stabilize fasting blood sugar below 8 mmol/L, patients with hypertension should stabilize blood pressure at normal level, and patients with chronic bronchitis should have no coughing and wheezing symptoms. This will ensure the safety of the surgery and prevent postoperative complications.
2, preoperative training, preoperative nurses should repeatedly train patients to gaze at the microscope light and maintain good fixation. Because intraoperative eyelid spasm and eye rotation are not conducive to smooth surgery, the patient should be encouraged to establish self-confidence and obtain good cooperation.
3. Use antimicrobial eye drops for 3 days before surgery to control local infected lesions in the eye. Patients with lacrimal tract infection should be treated and bacterial culture of the conjunctival sac should be performed, suggesting sterile growth before surgery.
4. Keep the bowels open. Some elderly patients suffer from constipation, which can easily cause serious postoperative complications such as postoperative anterior chamber bleeding and wound disintegration, thus affecting the surgical effect.
5.Sedatives, the use of appropriate sedatives before surgery is conducive to the elimination of patient tension and anxiety.
6, IOP-lowering drugs, for patients with combined glaucoma or orbital pressure tendency to be high, appropriate hypertonic dehydrating agents (such as 20% mannitol 30 min preoperative rapid intravenous drip) can be used before surgery to reduce intraocular pressure, reduce the possibility of intraoperative shallow anterior chamber, vitreous detachment and expulsion choroidal hemorrhage.
7, conjunctival sac rinsing, preoperative rinsing of the conjunctival sac with antiseptic solution and saline can reduce the possibility of infection.
8, eyelash treatment, internal eye surgery to cut the eyelashes, can facilitate the surgical operation and reduce the chance of infection.
