The laser used in Contoura
Contoura Vision is a technology that uses a topography-guided laser to correct refractive error, lowering or even eliminating the need for corrective eyewear such as glasses or contact lenses.
Why is this laser more effective?
Utilizing Contoura Vision technology reduces the related risks of LASIK and SMILE. It was approved by the US Food and Drug Administration in 2016. Contrasted with the 200 points provided by the wavefront-guided LASIK technique, the Contoura Vision technology provides a significantly more precise image of the eye’s surface. Before utilizing a laser to correct corneal defects, they are mapped out.
The new Contoura Vision TopoGuided LASIK technology is intended to improve the outcomes of LASIK surgery. Instead of basing vision correction on the patient’s requirement for corrective lenses such as glasses or contacts, as in traditional LASIK, corneal topography (maps of corneal curvature) is used. Contoura Vision uses the WaveLight Refractive Suite to accomplish Femto LASIK. The Bladeless Femtosecond technology of the FS 200 laser is originally utilized to create a narrow corneal flap. In a topographically guided laser ablation process for repairing refractive defects, the EX500 laser is utilized.
How does it work?
Vision Contouring with Contoura To do TopoGuided LASIK, a secondary diagnostic tool known as a topolyser, is used to measure 22,000 points on the cornea, noting imperfections’ curvature and optics. After merging the patient’s topographical data with their eyeglass prescription, a customized treatment profile is created and uploaded to the state-of-the-art laser.
The WaveLight EX 500 Excimer laser device eliminates any remaining tissue after all other laser ablation techniques have failed. Due to this approach, the corneal surface is optimized during the LASIK procedure. The Topolyser can identify and document even the slightest corneal curvature abnormalities, making it an indispensable diagnostic tool.
Compared to the current wave front-guided LASIK technique, which measures at approximately 200 points, it provides a staggering 22,000 points of measurement. Due to the precision with which topography is measured, all treatments may differ. This innovative technology corrects refractive errors with unmatched precision. Patients experience significantly improved visual acuity due to Contoura Vision’s integration of refractive prescription and corneal topography maps.
The Food and Drug Administration (FDA) found that patients who opted for this technology experienced a significant improvement in their eyesight and were able to see even more clearly without corrective eyewear. According to clinical trial statistics, over ninety percent of patients report seeing as well or better without glasses after surgery than before.
Improvement in vision
Several participants in US FDA clinical studies to validate Contoura Eyesight claimed vision improvements to levels exceeding 6/6 (or 20/20, the benchmark for normal vision). Only with the assistance of Contoura Vision has vision beyond 20/20 been consistently acquired. Over forty percent of individuals examined had vision superior to 20/20, meaning they could read at least one line further down the chart than a person with perfect vision. Additionally, 13.5% could read an additional two lines on the visual acuity chart.
The night vision of many individuals improved, with fewer incidences of glare, halos, ghost images, and reading and driving difficulties in the dark. Contrasted with LASIK and SMILE, Contoura demonstrated significantly superior visual outcomes.
Told, Contoura Vision is an extremely innovative, precise, and patient-specific LASIK treatment. The accurate corneal mapping given by cutting-edge technology enables eye doctors to provide individualized care for the eyes of their patients. These data are transmitted to the surgical planning computer, where they are assessed and used to accurately guide the laser beam in correcting the minute curvature variations at each end of the cornea.
Patients report seeing more clearly than ever before with conventional corrective lenses due to the revolutionary and individualized design of Contoura Vision. In addition to addressing refractive errors by modifying the basic shape of the cornea, topography-guided LASIK treats surface texture abnormalities. According to some studies, topography-guided LASIK can improve contrast sensitivity. Immediately following a Contoura Vision LASIK procedure (Visual Aids Centre), the patient’s vision will improve significantly.
However, the time required to get back on your feet varies significantly. For instance, a patient with a greater prescription may experience a slower return to health than one with a lower prescription. In addition to sleeping for about an hour in a postoperative room with protective eye shields, your laser eye surgeon will advise you to perform the following after surgery:
- You should plan for someone to drive you home from the hospital and pick up any necessary prescriptions after surgery.
- Please avoid touching your eyes and remember to clean them regularly.
- Put on eye protection and spend at least an hour at home unwinding.
- Adhere to any further postoperative instructions provided by your ophthalmologist.
Patients frequently report experiencing eye discomfort during the initial days following surgery. There may be some moderate side effects, such as red or watery eyes, for a few days after treatment. Still, most patients can return to their normal activities, including work, the day after.
