If you have a refractive error and want to eliminate it, then laser eye surgery is perfect for you! Laser treatment eliminates the need for glasses or contact lenses throughout your life.
An imperfect cornea or eyeball shape can cause refractive errors. The cornea is the transparent, transparent front part of the eye, responsible for bending and focusing light.
Vision correction surgery such as laser surgery can work by reshaping the cornea so that the light is focused on the retina.
Types of Refractive Errors
There are four main types of refractive errors:
Myopia (nearsightedness): A person with myopia can clearly see things close to him / her, but distant objects appear blurry.
Farsightedness (Farsightedness): People with distance vision can see distant objects clearly, but it is difficult to see close objects clearly.
Astigmatism: In astigmatism, objects appear blurry at any distance. This happens when the cornea becomes flat or unevenly curved, distorting vision far and near.
Presbyopia: Presbyopia is also called “aging eye”. This is a refractive error, where the eyes lose their ability to focus due to the natural aging of the person.
Risk factors and qualifications of laser surgery
Laser eye treatment is not for everyone. You may not be suitable for the following factors:
The cornea is too thin or irregular in shape
Eye disorders such as severe dry eyes
Age restriction (minimum age must be 18 years)
Factors such as pregnancy
Taking certain medications
If you have diabetes, rheumatoid arthritis and other health problems.
If your facial prescription is undergoing major changes
Why perform Lasik eye surgery?
Lasik stands for laser in situ keratomileusis; this is the most popular and recommended laser eye treatment.
Lasik eye surgery has been around for 25 years. Most people achieve their vision goals after surgery.
This is a painless operation and both eyes can be completed in 20 minutes.
Lasik does not include stitches or bandages.
No glasses or contact lenses
Complications that can occur after laser eye surgery
While laser surgery is usually a successful operation, some potential complications and side effects have been reported, such as:
Problems wearing contact lenses for other corrections
Loss of sight
Laser eye surgery: what to expect
For Lasik laser eye surgery
Before performing Lasik laser eye surgery, your eyes should be carefully evaluated. During the full evaluation, your doctor will perform a series of eye exams. He / she will measure your cornea to check if the shape, color and thickness are irregular.
Your eye doctor will watch for the following symptoms:
Inflammation of the eyes
Intraocular pressure (IOP)
It is also recommended that you usually stop wearing contact lenses two weeks before surgery. This is important because contact changes the natural shape of the cornea, which can affect the effectiveness of Lasik laser surgery.
Preoperative guidance for Lasik eye surgery
You will be asked to instill eye drops as directed by your doctor.
You may also be asked to take combylamine an hour before surgery to prevent allergies to the drug.
Two hours before Lasik eye surgery, you will be asked to eat light foods.
On the day of surgery, wash your hair and scrub your face with soap and water.
Do not use perfume, deodorant, or spray on the day of surgery.
Be sure to wear sunglasses on the day of surgery.
Stop contact lenses a few days before surgery.
Tell the doctor about your eye disease, history of allergies, or medical treatment.
During Lasik laser eye surgery
Before surgery, apply numb eye drops to the eyes to avoid pain or discomfort.
Then your eyes are under the laser. During the procedure, an instrument called an eyelid speculum is used to hold the eyelids open.
Before the corneal flap is cut, a suction cup is also placed in front of the eye to prevent eye movement and pressure.
The surgeon will then use a cutting laser to create a flap on the front of the eye. The flap of the cornea is slightly folded so that the surgeon can access your cornea to reshape it.
Then use an excimer laser according to your needs. You need to focus on the light spot in a short time. The laser then reshapes the cornea. During this process you may feel some pressure and hear a clicking sound.
After Lasik laser eye surgery
You should take a break just after you have completed Lasik’s laser eye surgery. You may experience ti after surgery
xamines your eyes the following day.
You will experience blurriness immediately after the surgery. However, this haziness goes away on its own and vision gets stabilized within a few days.
Take all necessary precautions as advised by your doctor, and you can get back to your routine in a week or two post laser eye surgery.
