While refractive errors in the eyes prevent the ability to choose distances, they significantly reduce the quality of life of patients. However, it is possible to treat visual disorders with modern methods. Contoura Vision technology stands out as a technology that allows you to see the colors of life more clearly.
What is Contoura Vision?
Lasik is a surgical procedure in which refractive errors in the eye are corrected using lasers instead of lenses that can be inserted into the eye. Lasik is limited to correcting only the refractive errors corrected by glasses. Contoura Vision application is the latest development in Lasik. In addition to correcting the refractive power of the eye, which can be corrected with glasses, Contoura Vision can also correct the defects of the surface of the cornea.
In which diseases is it applied?
Contoura Vision treatment; It is used in the treatment of refractive errors that cause blurriness in both far and near vision, such as nearsightedness and astigmatism.
What are the advantages?
Contoura Vision is the best LASIK surgery that can offer predictable and accurate treatment for perfect vision. Contoura Vision is an advanced version of Lasik that uses corneal topography to correct refractive error. It not only corrects the refractive error, but also removes surface defects in the cornea to provide sharp vision.
Contoura Vision is a personalized application. In addition to correcting the refractive power of the eye, it also corrects your corneal irregularities and works on the patient’s absolute visual axis. This is not possible in other laser applications.
Lasik laser eye surgery is the most universal and preferred application available in the eye industry. Lasik laser eye surgery is approved by the US FDA; Light deviations caused by irregularities on the eye surface can still be a problem in Lasik surgery. Contoura Vision is an application suitable for obtaining the best vision by removing topographic irregularities in the cornea.
Compared to previous topography-related laser treatments, Contoura Vision has been implemented as the most suitable Lasik application for the patient, with the new mapping technology, by making tissue ablation more precisely, as needed and at the minimum level.
How is Contoura Vision done/applied?
Basically, Contoura Vision is treatment linked to corneal topography. Topography maps are taken to collect data from the cornea. When a topography-related treatment is performed, it may be possible to restore the cornea to an ideal shape.
Lasik can produce good results by measuring 200 points of curvature on the cornea if there is sufficient corneal thickness. Contoura Vision, the latest version of Lasik and an “Advanced Topo Guided” procedure that makes the real difference, evaluates 22 thousand points. The targeted treatment is performed by uploading the personalized treatment profile information created on the computer to the computer of a state-of-the-art laser that applies the treatment to the cornea.
Before the laser surgery starts, special drops are dripped into the eye to prevent any discomfort during the procedure. The patient’s eye is then placed under the laser and an instrument called a lid speculum is used to hold the eyelids open. A vacuum is applied to the eye to prevent loss of contact that may affect eye movements or flap quality. After the corneal flap is created with laser, the surgeon shapes the cornea with Excimer laser under computer control.
While the laser sends a pulse of light to the cornea, the surgeon asks the patient to briefly look at the microscope target light. The shape of the cornea is corrected with a laser. Thus, images reach the retina at the back of the eye homogeneously, providing a clear, sharp vision.
Frequently asked questions about Contoura Vision
How long is the recovery period?
Recovery after the procedure occurs very quickly. In the control examination performed on the next day of the procedure, the patients usually have full vision.
Is the Contoura Vision method safe?
Laser surgery today is safer than it was 20 years ago. Because there has been a great deal of progress, not only in technology and the way it’s performed, but also in identifying patients who are ideal candidates. The Contoura Vision method is a much safer procedure than contact lens insertion.
What should be done before the procedure?
Before applying the Contoura Vision method, ophthalmologists must conduct a thorough examination to ensure that this procedure is healthy enough for the patient. First of all, the shape and thickness of the cornea; pupil size; refractive errors (myopia, hyperopia and astigmatism); The tear film on the surface of your eye is evaluated, as well as other eye conditions.
Preventive treatment may also be recommended to reduce the risk of dry eyes. Usually, a measurement called corneal topography is done to measure the curvature of the front surface of the eye and create a ‘map’ of the cornea. Soft contact lenses should be removed at least one week before the evaluation, and hard lenses three weeks before the evaluation, as they disrupt the natural shape of the cornea.
What are the causes of refractive errors in the eye?
The refractive errors, which are of interest to laser surgery, mainly occur for two reasons. The first is the increase in the axial length of the eye, and the second is the structural changes in the cornea. Refractive errors may develop due to changes in the intraocular lens, but this cannot be corrected by laser surgery.
What are the viewing rates that Contoura Vision brings?
Most Contoura Vision patients have reported vision equal to or better than glasses in clinical studies. The procedure is reported to reduce not only how much patients see, but also the severity of common visual complaints such as light sensitivity, difficulty driving at night, and glare.
In clinical studies, 92 percent of patients treated with Contoura Vision reported that their vision was 20/20 or better 12 months after their procedure. Some patients report better than 20/20 vision. A published study reports that about 65 percent of eyes treated with Contoura Vision were able to see 20/16 or better, with 34.4 percent able to see 20/12 or better.
