The popularity of corneal refractive therapy (CRT) as a means of vision correction is continuing to increase, one source has observed.
Rather than wearing glasses or other means of vision correction, people are turning to CRT and seeing almost immediate effects, according to optometrist Russel Lazarus, speaking to the Wentworth Courier.
He noted that CRT involves lenses smaller than contacts being worn overnight to correct the shape of the cornea, with patients generally noticing a difference within 24 hours.
"With the majority of patients, the next day they have clearer vision. In the small percentage where the prescription is very high, it takes two to three days," the expert told the newspaper.
As the treatment changes the cornea, Mr Lazarus said conditions such as astigmatism and short-sightedness can be targeted, which are often difficult to treat with lasers.
Specialists at Moorfields Eye Hospital NHS Foundation Trust in London pointed out that the preferred corrective procedure for people wanting to avoid wearing glasses has been excimer laser refractive surgery, but a new alternative is the insertion of phakic intraocular lenses.
