New laser may widen scope for eye surgery

New techniques in laser eye surgery could eliminate night vision problems and other undesirable side-effects of the treatment, enabling thousands more people to put aside their glasses and contact lenses.

The latest high-speed, high-precision lasers and iris recognition technology can provide customised procedures to replace the previous “one treatment fits all” approach, resulting in an operation that produces 20/20 vision or better, ophthalmologists say.

The innovations improve the popular LASIK (Laser in Situ Keratomileusis) method of eye surgery, which is used to correct sight and astigmatism – problems resulting from an irregular-shaped cornea.
