Mechanical methods in refractive corneal surgery

Curr Opin Ophthalmol. 1996 Aug;7(4):41-6. doi: 10.1097/00055735-199608000-00008.

Abstract

The past year has seen considerable advances and debate with regard to several new and some established mechanical means of refractive surgery. Lamellar in situ keratomileusis is gaining increased interest, especially for the treatment of moderate and high myopia, although considerable questions still exist with regard to its safety, predictability, and the possibility of loss of lines of best corrected visual acuity. Mini-radial keratotomy may be of benefit in reducing the risk of traumatic rupture of radial keratotomy incisions, and a refinement of the nomograms for astigmatic keratotomy in the treatment of congenital astigmatism has been proposed. Another report on the use of hexagonal keratotomy for the treatment of hyperopia again raised concerns of its predictability. A blind eye study of intrastromal corneal rings has provided some reassurance with regard to its safety but has also raised doubts over its predictability. Meanwhile, several more reports of the use of both anterior and posterior chamber phakic intraocular lenses for the treatment of myopia have been presented.
