Contoura Vision Surgery In Dhaka - Advanced Affordable Lasik Technique

Diagnosis Before Contoura Vision Surgery

Your ophthalmologist will perform the following tests to determine your suitability for the surgery:

• Visual Acuity Test: This measures the ability to distinguish letters, shapes, and details at a given distance to assess how sharp your vision is at a distance.
• Refraction Test: It is used to determine what prescription of lens or glasses you need to have normal 20/20 vision.
• Pentacam: This test produces a detailed image of the shape and the power of the cornea, much like creating a contour map of land. This is a painless test. If any retinal defects are discovered, these may be treated with a barrage laser first, followed by Contoura vision therapy 1-4 weeks later.
• Contrast Sensitivity Test: This measures your ability to distinguish between finer increments of light versus dark. Contrast vision is an important measure of visual function, especially in low-light conditions. Even if someone has 20/20 vision, certain medical problems can reduce contrast sensitivity.
• Pachymetry: Measuring the thickness of the cornea is important for assessing suitability for Countoura vision surgery.
• Wavefront analysis: A detailed description of the corneal irregularities is important for the ophthalmologist to create a customized treatment plan for each patient.

Treatment Of Contoura Vision Surgery In Dhaka

How To Prepare For Contoura Vision Surgery?

If you wear contact lenses, you would likely be advised by your ophthalmologists to stop using them. This is because these change the curvature and structure of the cornea, and those changes remain for a few weeks after you stop using them. The extent to which the cornea changes depends on the type of lenses being worn. Therefore, your eye surgeon will advise you on when to stop their use depending on the type you wear. If you do not stop using contact lenses prior to the surgery, it can lead to an inaccurate treatment plan and, therefore, a faulty treatment outcome.

What Happens During Contoura Vision Surgery?

The surgery takes 30 minutes to complete and will take place in the operating theatre. To numb your eye for this surgery, eye drops are used. A lid speculum keeps your eyes open during the following procedure:

• First, a femtosecond laser is used to produce a flap on the cornea.
• Next, an Ex500 excimer laser is used to ablate the corneal tissue to reshape it according to your customized treatment plan that was created using the Pentacam diagnosis test. This corrects refractive errors, resulting in improved vision.
• After the cornea is reshaped, the corneal flap is placed back onto the treated area. No sutures are applied as the cornea will heal on its own.
• Both eyes can be treated on the same day, and generally, most patients can recover within a day or two.

After Contoura Vision Surgery

After the surgery, you may experience itchiness or a burning sensation, and your ophthalmologist will discuss the medications and precautions you should take for your recovery. Eye drops may also be prescribed to prevent infections and facilitate healing. If you experience pain or discomfort, do not rub your eyes as this can cause the corneal flap to rupture. It is advised that you attend all post-operative check-ups recommended by your surgeon to ensure a smooth recovery.

Recovery After Contoura Vision Surgery

The following are some general tips to follow after surgery:

• Use Eye Drops As Prescribed: Strictly follow the recommended eye drops and medication advice from your doctor. Remember to wash your hands before putting the eye drops and shake the bottle well before use.
• Use lubricating eye drops: You may use lubricating eye drops to prevent dry eyes, but do so as prescribed by your doctor.
• Practise Good Hand And Eye Hygiene: Clean your eyes with sterile lid wipes to prevent any chance of infection.
• Avoid Straining Eyes On The Day Of Surgery: Avoid reading, watching TV, or driving after your surgery. Also, limit the use of computers or smartphones and preferably sleep after your surgery to give your eyes much-needed rest.
• Wear Protective Sunglasses: When outdoors, wear sunglasses to protect your eyes from glare and dust. This can also discourage you from rubbing your eyes and any accidental trauma. An eye shield is recommended to prevent inadvertent rubbing and injury to the eyes during sleep.
• Avoid Swimming For The Next Few Days: Ensure no water enters your eyes for the first few days. This may mean using a bucket to shower and avoiding swimming.
• Attend All Follow-Up Appointments: Postoperative appointments are crucial to review your healing, so make sure not to miss any of these.
• Contact Doctor For Any Concerns: In case of pain, watering or any redness beyond the first day, contact your doctor immediately for advice.

Risks And Complications Of Contoura Vision Surgery

You may experience minor complications following your surgery. These could include:

• Dry Eyes: This is usually temporary and is due to the eye not producing enough tears.
• Blurry vision: This is a common occurrence immediately after the surgery but is resolved within a few days.
• Double vision: Pupils can dilate during the surgery, leading to this temporary phenomenon.
• Glare or halo: This is a common occurrence post-surgery, especially at night, but decreases with time.
• Sensitivity to light: Glasses can help reduce any sensitivity to light.
• Eye pain: Artificial tears can help relieve eye pain.
• Corneal Ectasia: In rare cases, there may be a removal of extra corneal tissue during the surgery. This can weaken the cornea and cause it to bulge forward. This can occur in cases where a high amount of nearsightedness needs correction.
