Topography-guided Lasik is known as Contoura Vision Surgery

Topography-guided LASIK, also known as Contoura Vision or Topoguided contour or Wavefront-guided LASIK, is a type of laser eye surgery that utilizes detailed corneal topography measurements to guide the laser treatment. Contoura Vision Surgery is used to correct the refractive errors like farsightedness, nearsightedness and astigmatism.

It is a more advanced and personalized form of LASIK surgery compared to traditional LASIK.

During a topography-guided LASIK procedure, we first obtains a precise map of the cornea's surface using Pentacam and sirius topographer. These scans provide us with a detailed information about the shape, curvature, and irregularities of the cornea. The data from these scans are then optimized inb creating a personalized treatment plan for each eye of each patient.

The laser used in topography-guided LASIK is programmed to treat the specific irregularities identified in the cornea. The laser ablation pattern is based on the patient's unique corneal topography, allowing for a more customized and precise treatment. This personalized approach aims to correct not only common vision problems like nearsightedness, farsightedness, and astigmatism but also subtle corneal irregularities that can affect visual quality.

Topography-guided LASIK has several potential advantages over traditional LASIK:

• Advanced and Enhanced Visual Outcomes: The personalized treatment based on corneal topography can potentially result in better visual acuity and quality of vision compared to conventional LASIK.
• Treatment of Irregularities: Topography-guided LASIK can address corneal irregularities, such as higher-order aberrations, which are not typically corrected by traditional LASIK. This can be beneficial for patients with irregular astigmatism, corneal ectasia, or previous corneal surgeries.
• Reduced Risk of Induced Irregularities: The precise and individualized nature of this surgery reduces the risk of post-operative complications such as glare, halos, and compromised night vision.
• Customized Treatment: Each patient's corneal topography is unique, and topography-guided LASIK allows for a more individualized treatment plan tailored to the specific characteristics of the patient's eyes.
• Enhanced Quality of Life: Patients who undergo this eye surgery, often experience a significant improvement in their quality of life, enjoying greater freedom and convenience in their daily activities without the constant reliance on glasses or contact lenses.

Topography-guided LASIK Procedure

• Pre-operative Examinations: Before the surgery, a comprehensive eye test is conducted to see the patient's eye health, determine their eligibility for the procedure, and collect the necessary data for the surgery.
• Corneal Topography: It is an advanced technology, used to create a detailed map of the cornea, identifying its irregularities and deviations.
• Customized Treatment Plan: Based on the corneal topography results, a personalized treatment plan is developed to address the specific refractive errors and irregularities present in the patient's eyes.
• Laser Reshaping: During the surgery, an excimer laser is used to precisely reshape the cornea according to the customized treatment plan. The laser removes microscopic amounts of tissue, correcting the refractive errors and improving visual acuity.
• Recovery and Follow-up: Following the procedure, patients are provided with post-operative care instructions and scheduled for follow-up visits to monitor the healing process and ensure optimal visual outcomes.

This topography-guided LASIK may not be suitable for every eye, and a thorough evaluation by an experienced ophthalmologist is needful to determine the most appropriate treatment for an individual's specific vision needs.

FAQs: Everything You Need to Know

• Is Contour Vision suitable for everyone?
  No but Contour Vision is suitable for many individuals with refractive errors such as nearsightedness, farsightedness, and astigmatism. However, each patient's eligibility will be determined through a thorough evaluation and consultation with an eye care specialist.
• How long does this procedure take?
  The actual procedure itself typically takes around 10-15 minutes per eye, but you should expect to spend a few hours at the eye care center for pre-operative preparations and post-operative evaluations.
• Does this surgery hurt?
  During the procedure, you will receive numbing eye drops to ensure your comfort. While you may feel some pressure or mild discomfort, it is generally not painful. After the surgery, you may experience some temporary dryness or slight irritation, which can be managed with prescribed eye drops.
• Are there any risks or complications associated with this eye surgery?
  As with any surgical procedure, there are potential risks and complications, although they are rare. These may include dry eyes, glare, halos, infection, or overcorrection/undercorrection. Your eye care specialist will discuss these risks and provide you with detailed information to make an informed decision.
• Am I a suitable candidate for Topo Guided Contour surgery?
  Candidates should have stable vision prescription, good overall eye health, and realistic expectations. An eye evaluation by our specialist will determine your eligibility.
• What Vision Problems Does this surgery correct?
  Contour Vision is effective in correcting nearsightedness (myopia) and astigmatism, as well as improving overall visual acuity and contrast sensitivity.
• Will I still need glasses or contacts after the Surgery?
  Many patients achieve excellent vision without glasses or contacts after this eye surgery. However, some may still need them for certain tasks or activities.
