Advanced technologies are created in the healthcare field to make the life of patient more comfortable and healthier. Technological advancements are a must in this field because many patients are not able to get the benefit of the technologies available in the industry. Such patients either suffer from altogether new disease or the disease is gone into an advanced stage and is not being treated with the current system of medications and surgery. Spectacles removal surgery is not isolated from these advancements. Scientists are trying their best to make available surgical treatment with the least complications and desired results. One such advanced surgery is Contoura Vision surgery, which is also known as Topography-guided LASIK surgery. This surgery is an advanced version of LASIK surgery and provides enhanced benefits to the patients who are considering to undergo spectacle removal surgery. Not only this surgery is effective in general patients but is also offer good results in patients who were not eligible for undergoing LASIK surgery due to irregularities in the cornea. The technology has been approved by USFDA for removal of the specs.
The trend of using the spectacles for correcting the vision is dated back in the 13th century. In the 1800s, contact lenses were available in Switzerland by manufacturing from hand-blown glass. These were the non-invasive methods for correcting the vision and improving visual clarity. However, these devices cause discomfort to the patient and require extensive careful handling. This results in the introduction of invasive methods for correcting the vision. A Russian eye specialist developed radial keratotomy, which involves the use of a diamond knife to make an incision on cornea and alter its curvature. The process is still in use to manage astigmatism. Later, in the 1990s, USFDA approved a more powerful procedure for correcting the vision. The process is known as photorefractive keratotomy which has a long-lasting vision correction. LASIK acquires the advantages of both the above techniques and remove their disadvantages leading to much more comfort to the patient. These techniques are highly successful and still considered as Gold standard in vision correction surgery.
In 1999, there emerged a customized procedure done through LASIK through wavefront analysis. The technique was known as Contoura technique and provide 22000 points on the cornea. As compared to Contoura, the conventional LASIK maps only 200 points on the cornea.
Topography-Guided LASIK treatment is not for all the patients suffering from vision problems. The ophthalmologists would conduct a comprehensive evaluation of eye health to determine whether the Contoura vision surgery provide any benefit to the patient in improving visual clarity or correcting refractive error. Following patients are not eligible for undergoing Contoura vision surgery:
The doctor will determine other criteria on a case-to-case basis.
Following are some of the difference between Contoura vision surgery and LASIK:
Better results: The results of Contoura surgery are better as compared to LASIK in terms of visual clarity and correction in refractive error. Some of the patients experience corrections better than 6/6.
Broader scope: The scope of Contoura is not limited to vision correction rather it can treat the abnormality in the corneal curvature.
Advanced technology: The technology used in Contoura surgery is more advanced as compared to conventional LASIK surgery. While the conventional LASIK surgery maps only 200 points on the cornea, the Contoura vision surgery maps 22000 points on cornea.
Fewer complications: Contoura vision surgery has fewer complications as compared to conventional LASIK surgery. The damage to the tissue is relatively less and has faster healing time.
Contoura vision surgery has been approved by USFDA for vision correction. The approval is done after evaluating the comprehensive studies done by the applicant or the innovator. A study concluded that better than 100% vision was achieved in the patients undergoing Contoura vision surgery. It was also found that in the three-month follow-up, the Contoura vision surgery was far more superior as compared to SMILE.
Following are some of the benefits offered by Contoura vision surgery:
High safety standards: The Contoura LASIK follows high safety standards. The complications are minimized and the healing is faster.
USFDA approved: Contoura LASIK has been approved by USFDA for vision correction. This indicates the safety, efficacy, and authenticity of this technology.
Patient’s comfort: Contoura surgery have no stitches, no injections, no pain, no bandages, and the patient may go home the same day of surgery.
Contoura vision surgery is also known as Topography-guided LASIK surgery. The process followed is similar to the LASIK surgery, however, the technology involved is different from conventional LASIK surgery. Detailed eye check-up of the patient is done to exclude the presence of any disease of infection. The surgery is performed under the effect of local anaesthesia. In this advanced technology, the machine used makes almost 22000 points on the cornea through topography. Every point is analyzed for abnormality and is corrected through LASER. The machine that is involved in the Contoura vision includes WaveLight EX500 Excimer Laser Systems and WaveLight TopolyzerVario Diagnostic Device. Post-surgery eye care is an important part of the treatment to achieve the desired result. Various eye drops including anti-inflammatory and antibiotics are prescribed to the patient to prevent inflammation and infection respectively.
Various centres claim to perform the Contoura vision with high success rates. Some of them are genuine while others make false and ambiguous claims. As eyes are vital organs, due diligence should be done in deciding the centre for undergoing Contoura vision surgery. Many centres advertise that they are performing Contoura vision but instead the surgery is done through conventional LASIK. Ask about the experience from friends or family members who have undergone Contoura vision surgery. You may also contact the doctor performing best Contoura vision surgery in India.
