What is Contoura Vision?
Contoura Vision is an advanced laser eye surgery technology designed to correct refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
Unlike traditional LASIK, Contoura Vision goes a step further by mapping up to 22,000 points on the cornea to create a highly personalized treatment plan. This helps to provide sharper vision, reduce visual distortions like halos or glare, and improve night vision.
Different Types of Contoura Vision
Contoura Vision is a topography-guided LASIK procedure that offers personalized vision correction. While Contoura Vision itself is a specific type of LASIK, here are some variations and related procedures:
- Contoura LASIK: The standard procedure using topography-guided technology to map the cornea and correct refractive errors.
- Contoura PRK: A surface ablation procedure that uses topography-guided technology, ideal for patients with thin or irregular corneas.
- Custom Contoura: Some clinics offer customized Contoura procedures tailored to individual patient needs, incorporating advanced diagnostics and treatment planning.
When discussing Contoura Vision, it's often compared to or combined with other LASIK types, such as:
- Wavefront-Guided LASIK: Uses wavefront technology to map the eye's imperfections.
- Wavefront-Optimised LASIK: Maintains the natural corneal shape, reducing side effects.
These procedures aim to provide precise vision correction, but the best option depends on individual factors, such as corneal thickness, refractive errors, and personal preferences. Consult an experienced eye surgeon to determine the most suitable procedure for your needs.
Is Contoura Vision Safe?
Yes, Contoura Vision is considered safe and highly effective when performed by an experienced ophthalmologist. It is FDA-approved and has shown excellent results worldwide. Some safety aspects include:
- Precision Mapping: With detailed corneal mapping, the treatment is highly personalized, reducing risks.
- Better Visual Outcomes: Studies show improved clarity, contrast sensitivity, and reduced dependency on glasses or contact lenses.
- Quick Recovery: Most patients resume normal activities within a few days.
- Minimal Side Effects: Compared to traditional LASIK, side effects such as glare, halos, or dry eyes are significantly reduced.
While it is safe, not everyone is an ideal candidate. A detailed eye examination by a specialist is essential before deciding on the procedure.

Who Needs Contoura Vision?
Contoura Vision is recommended for people who want sharper, clearer vision and reduced dependence on glasses or contact lenses. It is especially suitable for adults with stable vision, healthy corneas, and those seeking a personalized, precise approach to laser vision correction.
What conditions does Contoura Vision treat?
Contoura Vision corrects several types of refractive errors and corneal irregularities, including:
- Myopia (Nearsightedness): Difficulty seeing distant objects clearly
- Hyperopia (Farsightedness): Difficulty seeing close objects clearly
- Astigmatism: Blurred or distorted vision caused by irregular corneal curvature
- Corneal Irregularities: Uneven corneal surface affecting visual sharpness
When would a doctor recommend Contoura Vision?
A doctor may recommend Contoura Vision if you have stable vision that has not changed significantly for at least a year, healthy corneas, and want a safer, more precise alternative to traditional LASIK. It is often suggested for patients seeking faster recovery, reduced glare and halos, and superior night vision.
Why is Contoura Vision Done?
Contoura Vision is performed not just to correct the eye's refractive power, but also to address corneal irregularities for sharper, more natural vision. The procedure is ideal for those looking to improve overall visual quality and reduce reliance on corrective lenses. Many patients choose Contoura Vision to achieve:
- Enhanced clarity and contrast of vision
- Faster visual recovery
- Reduced visual disturbances such as glare and halos
- Improved night vision compared to standard LASIK
It is recommended to get a second opinion from trusted eye specialists before proceeding to ensure the procedure is suitable for your eyes and lifestyle.
How to Prepare for Contoura Vision?
Proper preparation for Contoura Vision ensures the best possible outcome and a smooth recovery. Following your surgeon's guidance is essential for safety and effectiveness.
How should I prepare before Contoura Vision?
To prepare for Contoura Vision surgery:

- Discuss Medications: Inform your surgeon about all prescription drugs, over-the-counter medications, and supplements. Some medicines may need adjustment before the procedure.
- Stop Wearing Contact Lenses: Contact lenses can change the shape of your cornea. Stop using them before the surgery as advised: soft lenses usually one week before, toric lenses for astigmatism a few weeks prior.
- Follow Pre-Operative Instructions: Avoid eye makeup, lotions, and perfumes on surgery day. Follow any other specific instructions your surgeon provides.
- Arrange Transportation: You will not be able to drive immediately after surgery, so plan for someone to take you home.
- Plan for Recovery: Schedule a day or two of rest post-surgery and avoid demanding activities.
- Get a Good Night's Sleep: Being well-rested helps with comfort and recovery.
- Wear Comfortable Clothing: Loose, comfortable clothing makes the procedure more relaxing.
What tests are done before Contoura Vision?
Before the procedure, your surgeon may perform several tests to ensure safety and precision:
- Comprehensive eye examination to assess vision and ocular health
- Corneal topography to map the cornea for a personalized laser treatment plan
- Measurement of pupil size, refractive error, and corneal thickness
- Evaluation for any eye conditions such as dry eyes, glaucoma, or cataracts
Should I stop eating, drinking, or taking medicines before Contoura Vision?
- Follow your surgeon's instructions regarding fasting before the procedure. An empty stomach can prevent nausea during surgery.
- Continue or adjust medications only as advised by your doctor.
- Avoid alcohol or recreational substances for at least 24 hours before surgery to ensure safety.
Steps Involved in Contoura Vision Procedure
Contoura Vision, also called Topography-Guided LASIK, is an advanced laser eye surgery designed to provide highly personalized and precise vision correction. It corrects refractive errors and subtle corneal irregularities to improve overall visual quality.
What Will Happen During Contoura Vision Surgery?
The procedure is carefully structured to ensure safety, comfort, and optimal outcomes:
- Surgery Preparation: You will be positioned comfortably, and numbing eye drops will be applied to prevent discomfort.
- Flap Creation: A thin corneal flap is generated using a microkeratome or femtosecond laser to access the underlying tissue.
- Laser Correction: While focusing on a target light, an excimer laser reshapes the cornea by removing small amounts of tissue to improve vision.
- Corneal Mapping Guidance: The laser follows a detailed corneal topography map to correct both refractive errors and corneal irregularities.
- Flap Replacement: The corneal flap is delicately repositioned and naturally adheres without stitches.
- Post-Operative Check-up: Your surgeon examines your eyes to ensure proper alignment and addresses any concerns.
- Recovery Process: Protective eye shields may be used, and patients follow instructions regarding eye drops and limiting eye strain.
- Follow-up Visits: Regular appointments monitor healing and assess visual improvement.
- Treatment Duration: The laser portion takes only a few minutes per eye; the entire procedure including preparation and observation takes about two hours.
- Comfortable Procedure: The surgery is painless, although slight pressure may be felt during flap creation.
- Visual Enhancement: Many patients notice improved vision immediately, with stabilization occurring over a few days.
How is Contoura Vision Performed?
