Cataract is a cloudiness of the natural lens in the eye. It may cause impaired vision, glare, and/or letters that appear double.
The lens lies in a lens capsule. During cataract surgery, the unclear lens is removed by ultrasound keeping the lens capsule intact. A new clear lens is placed in the lens capsule which is fitted to your eye based on pre-examination measurements.
The surgery is usually done under local anesthesia on an outpatient basis.
Most people will experience a better vision after surgery unless there are other visual disturbing conditions in the eye.
Pre-examination before surgery
- Bring your glasses
- Bring your health card (Sundhedskort)
- Do not use soft contact lenses 24 hours prior to the examination
- Do not use hard contact lenses 72 hours prior to the examination.
An examination of your eye will be made.
Note: Eye drops will be used to widen/dilate your pupils. This will cause blurred vision and increased sensitivity to light for approximately 4 hours. Therefore, we advise you to bring a pair of sunglasses. Furthermore, we strongly recommend that you do not drive yourself.
The decision for surgery will be made based on
- Your vision
- The amount of cataract
- If you drive a car: How close are you to the needed visual acuity limit.
If both eyes need surgery, you will be given an appointment for the procedure where both eyes will be done on the same day. In some cases though, two separate appointments are given on two separate days.
If you are used to read without reading glasses, you should consider if you
