Scientists claim that the synthetic lens might be a safer way of correcting myopia than correcting it with laser…
Allon Bars, a doctor from the British public eye hospital Moorfields Eye Hospital in London conducted a Cochrane systematic analysis of published papers that deal with testing the accuracy and safety of both therapeutic methods.
Cochrane Collaboration is an international nonprofit organization working to promote evidence-based medicine, and members of the organization on the basis of unifying previously conducted tests provide the answer to a medical issue.
Laser surgery is often used to correct vision in nearsighted people, but an increasing number of ophthalmologists recognize possible advantages of using facic intraocular lenses.
While laser surgery moves parts of the cornea in order to change the way that light enters the eye, with the new method the same effect is achieved thanks to the insertion of synthetic lens in front of our own lens.
The researchers analyzed data collected in three studies that have sought differences between these two therapeutic procedures, in which a total of 228 eyes was treated.
One year after surgery both procedures resulted in approximately the same number of people with perfect eyesight. However, patients who underwent the implementation of synthetic lenses had a clearer vision and better contrast, and were more satisfied with the performed therapeutic procedure.
“Our discovery shows that the incorporation facic intraocular lenses in patients with moderate myopia is a safer way of correcting vision than laser correction,” explained the author of this analysis.
Intraocular lenses are commonly used to treat cataracts, a disease in which the lens of the eye becomes blurred, and vision is reduced.
