Lasik eye surgery or laser vision correction

Lasik eye surgery is commonly referred to as laser eye surgery or laser vision correction. It is a type of refractive surgery done to correct common eye defects like nearsightedness, farsightedness, and/or astigmatism.

How it works?
In nearsighted people, surgery is done s to flatten the too-steep cornea; with farsighted people, a steeper cornea is desired. It can also correct astigmatism by smoothing an irregular cornea into a more normal shape.

What are the advantages of Lasik surgery
○ It corrects vision.
○ Lasik surgery is less painful due to the numbing drops that are used.
○ Faster healing.
○ No surgical dressings or stitches are required after surgery.
○ Surgery can be repeated after years to further correct vision if vision changes.
○ Most patients have a dramatic reduction in eyeglass or contact lens dependence and many patients no longer need them at all.

Possible risks of Lasik eye surgery
○ Lasik surgery is technically complex. Rare problems may occur when the doctor creates the flap, which can permanently affect vision.This risk can be decreased by choosing a experienced surgeon. – Lasik can rarely cause a loss of “best” vision. Best vision is the highest degree of vision that achieved while wearing contact lenses or eyeglasses. Potential side effects of Lasik eye surgery?
○ Some patients experience discomfort in the first 24 to 48 hours after the surgery. Other side effects, although rare, may include:
■ Glare ■ Seeing halos around images ■ Difficulty driving at night ■ Fluctuating vision ■ Dry eyes

What are the preparation for surgery?
○ Get enough information from the surgeon regarding what is expected during and after surgery
○ Undergo the pre surgery examinations as explained by the doctor
○ If you wear rigid gas permeable contact lenses, you should not wear them for at least three weeks before your evaluation. Other types of contact lenses shouldn’t be worn for at least three days prior to the evaluation. Be sure to bring your eyeglasses to the surgeon so your prescription can be reviewed.
○ On the day of your surgery, eat a light meal before going to the doctor and take all of your prescribed medications.
○ Do not wear eye makeup or have any bulky accessories in your hair that will interfere with positioning your head under the laser machine .
○ If you are not feeling well that morning, call the doctor’s office to determine whether the procedure needs to be postponed.

What happens during the surgery?
Lasik is performed while the patient is under local anesthesia in the form of eye drops and usually takes about 10 minutes to complete. Patients may also request mild sedation. Plan to have someone drive you home after surgery.

What is expected after the surgery?
○ Eyes will temporarily be dry even though they do not feel that way. Your doctor will give you prescription eye drops to prevent infection and inflammation and eyedrops to keep your eyes moist. These drops may cause a momentary slight burn or blurring of your vision when you use them.
○ Do not use any eye drops not approved by your eye doctor.
○ Healing after Lasik eye surgery usually occurs very rapidly. Vision may be blurry and hazy for the first day, but most patients notice improved vision within a few days of surgery.
○ Specific follow-up after the surgery varies from one surgeon to another. You will revisit the doctor for an evaluation 24 to 48 hours after Lasik eye surgery, as well as at regular intervals within the first six months.
