Before you have cataract surgery, you need to know this!

Many cataract patients have such questions before surgery.

What tests will be done before cataract surgery?

01. What should you pay attention to before cataract surgery?

First of all, you need to maintain a good physical condition and avoid colds, chills, etc. At the same time, you must control your blood pressure and blood sugar within the standard range.

During the period before the operation, remember to use antibacterial eye drops as prescribed by the doctor; get enough sleep and eat a healthy diet, especially the night before the operation. Eat a healthy diet on the day of the operation and avoid overeating or eating irritating foods.

In addition, on the day of the operation, try not to wear makeup, keep your face and hair clean, wear light and comfortable clothes, and avoid wearing high collars, pullovers, etc.

Wang Yong, deputy director of the Cataract Subcommittee of the China Association of Non-public Medical Institutions, said: Paying attention to these matters before cataract surgery and doing a good job of preoperative protection can effectively avoid adverse factors, help yourself perform the surgery better, and restore clear visual quality after surgery.

02. What examinations will be done before cataract surgery?

Before cataract surgery, we need a complete set of professional and standardized preoperative examinations to determine your eye condition and customize your surgical plan.

There are more than ten routine preoperative examinations for cataract surgery, which are mainly divided into three categories:

1. Examinations to clarify the diagnosis and surgical indications, such as visual acuity measurement, intraocular pressure measurement, comprehensive optometry, slit lamp microscopy, and fundus examination;

2. Examinations to exclude surgical contraindications, such as electrocardiogram, blood routine, urine routine, lacrimal duct irrigation, corneal endothelial cell counting, eye B-ultrasound, etc.

3. Clarify the surgical plan and the selected artificial lens examination, such as: eye biometry, eye AB ultrasound, etc., to understand the patient's eyeball length, corneal curvature, astigmatism, etc., so as to select the appropriate artificial lens.

If you choose femtosecond laser cataract surgery or refractive intraocular lens implantation, there are some other examination items, such as optical coherence tomography, ocular surface comprehensive analyzer, and visual quality analysis. Zhou Li, deputy director of the Cataract and Presbyopia Department of Aier Eye Hospital Affiliated to Wuhan University, said: Through the above comprehensive examinations, we can understand the patient's eye and body conditions, so as to customize a personalized surgical plan. The night before the examination, we should let our eyes get enough rest, keep our eyes clean on the day of the examination, and do not wear eye makeup or spray volatile items such as perfume.
