Orthokeratology (also known as corneal reshaping therapy) contact lenses are worn overnight to change the shape of the cornea and correct refractive errors for the following day. Slowly, more and more patients decide to give them a go, encouraged by eye care experts, one of whom has recently compared them to corrective braces.
According to the former president of the College of Optometrists, Dr Kevin Lewis, orthokeratology contact lenses are constantly improved by their manufacturers. As a result, an increasing number of patients can take advantage of their benefits.
Usually, the expert added, eye care practitioners fit orthokeratology contact lenses in myopic children, in whom such lenses act similarly to corrective dental braces, reducing the progression of the condition.
The effectiveness of using corneal reshaping therapy contact lenses to slow down the progression of short-sightedness has already been confirmed by several studies. However, more long-term clinical trials are necessary to ensure that this form of treatment can start to be routinely used by eye care professionals.
