Diagnose any refractive error you have and measure both the curvature of your cornea and the length of your eye to help determine the type and power of lens you will need. Examine the external parts of the eye, such as the eyelids, cornea, pupil and lens. Place drops in your eye to dilate your pupils, so the doctor can look closely at the back of your eye. If you have had laser vision correction before, the doctor may conduct additional tests and may ask you to obtain your pre- and post-operative LASIK data for reference, if possible.
Your ophthalmologist will also ask for a full health history, including what medications you are currently taking and what medications you have taken in the past. Certain health conditions, including diabetes, diabetic retinopathy, autoimmune diseases, glaucoma, corneal disease and age-related macular degeneration may need special discussion. Some of these may hasten or delay when you’ll need to have cataract surgery and may make you more prone to some complications.
The preoperative examination includes
- If you are a contact lens wearer, they should be removed at least 3 days for soft contact lens and at least 7 days for
- hard, semi hard or rigid gas permeable lens prior to the appointment date.
- Due to the blurry vision that results after the dilatation of the pupil, it is recommended that the patient be accompanied by a relative or close friend. Dilation causes the eyes to become extremely light sensitive and the patient might not be able to drive a vehicle after dilating the pupil.
- Bring all your current medications on the appointment. The doctor may recommend that you stop taking certain medications at least a few days prior to the operation. But it may be fine to continue other important medications.
- Bring sunglasses is recommended.
- It will take 2-3 hours for the complete eye examination.
