Sorted out the pre- and post-operative.

What to know before cataract surgery.

Cataract patients need to check their general condition before surgery: blood routine, urine routine, blood glucose, liver function, kidney function, blood pressure, electrocardiogram and eye examination: visual acuity, corneal flexion or corneal topography, corneal endothelial count, ultrasound, intraocular pressure measurement, tear duct irrigation, etc., and preoperative antimicrobial eye drops are used to spot the eyes.

What to know after cataract surgery.

1. On the day of surgery and within 1 month after surgery, you should rest as much as possible, avoid bowing your head, coughing violently, doing heavy physical work, lifting heavy objects, and holding children; When washing the face and bathing, avoid splashing dirty water or soapy water into the surgical eye, causing wound infection; Do not apply any pressure to the eye (including rubbing, blinking, etc.) and prevent eye trauma.

2. On the day of surgery and within 1 week after surgery, you should sleep in a semi-recumbent position as much as possible, and avoid sleeping on the side of the eye side of the operation, so as not to cause the wound to dehiscence.

3. Come to the hospital for re-examination on the morning of the first day after surgery and the next week after discharge, and determine the medication situation and the date of the next follow-up according to the doctor's instructions.

4. The visual acuity on the first day after surgery may not be significantly improved due to the impact of surgical inflammation and corneal edema, but the visual acuity will be improved after 3 days of medication (except for those with other eye diseases).

5. Try to eat less spicy food within two weeks after cataract surgery, do not smoke and drink, and those with dry stools should take intestinal moisturizers to avoid excessive stool force, which will lead to wound dehiscence or intraocular lens displacement, and even lead to intraocular lens prolapse.

6. Go home after surgery and get some anti-inflammatory eye drops, Dianbishu eye solution: 6 times a day in the first week after surgery, and 4 times a day in the second week; Topicamide ophthalmic: 2 times a day for the first week after surgery (some patients will have dizziness and unclear vision after applying the drug, which is a normal reaction), 1 time per night for the second week, and the above two drugs will be discontinued after two weeks!

After traumatic or concurrent cataracts, drugs should be administered according to the condition of the surgical eye**.

7. After surgery, eye flowering, mild foreign body sensation, subconjunctival spotted patchy hemorrhage, and conjunctival hyperemia are all normal phenomena, if there is obvious eye swelling and pain, headache, nausea, vomiting or sudden loss of vision, please go to the hospital immediately!

8. If the vision is unstable within 3 months after surgery, refractive examination should be done after 3 months, and a pair of low-power glasses should be used if necessary, and the vision of seeing far or near should be adjusted to achieve the best effect.

9. If the child does not have an intraocular lens implanted after cataract surgery, he or she needs to be fitted with glasses and amblyopia training in time, and rechecked regularly.

1. Before surgery, the doctor should conduct a detailed physical examination of cataract patients, including heart, lungs, liver, blood pressure, electrocardiogram, and if necessary, blood glucose and blood calcium examinations should be done to ensure that the blood pressure of hypertensive patients and the blood sugar level of diabetics are within the normal range, and then surgery is appropriate.

2. The doctor should check the patient's visual function, visual acuity, light positioning, color discrimination (or traffic light discrimination), A, B ultrasound, and electrovisual physiological examination; inflammation of the back of the eye, conjunctiva, and urethra; anterior chamber depth, with or without retrocorneal deposition; whether the aqueous humor is cloudy; whether the pupils are dilated and whether the iris is adhesion or atrophy; the nature of neovascularization and crystal turbidity, and the presence or absence of dislocation; vitreous and fundus conditions. Surgery should not be performed if the surgical indicators are not met.

3. For cataract patients, start taking antibiotics or washing their eyes three days before surgery according to the doctor's instructions to prevent eye infection.
