Surgical insertion of lens in the eye might be a safer method in vision correction than laser surgery
Lasik is not new to us. The use of laser in correcting vision problems in people has been there for quite sometime. The latest news on vision correction suggests that inserting a plastic lens by surgical methods inside the eye [ "either behind the pupil or in front of the iris"] yields a better result as compared to laser surgery. The procedure is called Phakic IOL Treatment and uses Intra-ocular Lenses (IOLs).
This method has been considered a safer approach than laser surgery by researchers at Moorfields Eye Hospital in London.”Two of the studies involved lenses which are “clipped” on to the eye, while another looked at a different type which are naturally suspended in the eye.” Although this operation was carried out for patients who were extremely short sighted, the doctors think that this method could be a potential replacement of laser surgery in the future. The next thing in consideration by the researchers is the long term effect of the IOLs in patients, which is yet to be clarified.
