Dear Mr./Ms.________________:

Sincerely thank you for choosing Jiahui International Hospital to provide you with cataract surgery. We provide this manual to help you understand what you need to prepare for this surgery. Proper preparation will help you cope with the surgery easily and facilitate your postoperative recovery. Please read this manual carefully and feel free to ask questions to learn more about surgical announcements.

Pre-operation

1）Instructions for Use of Preoperative Eye Drops:

Antibiotic eye drops should be applied to the operative eye 3 days before surgery, 1 drop/time QID.

2）Please refer to the figure below for the usage of eye drops

3）If you wear contact lenses, please stop wearing them one week before surgery.

4）Please clean your eyes and avoid makeup on the day of surgery.

5）If local anesthesia is applied, normal food intake is allowed before surgery; fasting and water restriction are not required.

6）Attention should be paid to preoperative changes in blood glucose for diabetic patients: for vitreoretinal surgery, 2-hour postprandial blood glucose should be monitored on the day of surgery; if the blood glucose level is above 13mmol/dl, surgery will be rescheduled until it remains below 13mmol/dl.

7）Please inform your doctor or nurse in case of preoperative eye infection or inflammation.

8）Instructions for registration time: on the day of surgery, if you will undergo local anesthesia, please arrive at the front desk (next to the pharmacy) on the first floor of the Clinic one hour before surgery, and an operation room nurse will pick you up to the Operating

Room; if you plan to undergo general anesthesia, please arrive at the front desk of the hospital 2 hours in advance since your surgical team needs to make some preparations for you and take notes for some documents before general anesthesia.

Postoperative Instructions for Cataract Surgery

1.Postoperative use of eye drops: apply eye drops for 2-4 weeks (as instructed), 6 times daily for the first three days and QID thereafter, or as instructed; use of mydriatics: 6 times daily for the first three days and QID thereafter, or as instructed; different eye drops should be applied at an interval of more than 10 minutes, 1 drop/time.

2.Within one month after cataract surgery, the doctor will prescribe hormonic and antibiotic eye drops for the affected eye to prevent adhesions of pupil after mydriasis.
