Radial corneal sutures for the correction of myopia: a laboratory experiment.

Radial interrupted nylon sutures were placed in the corneas of fourteen human donor eyes, in a laboratory setting, to produce a reversible surgical correction of myopia. Significant corneal flattening was achieved when a small optical zone (4-5 mm) was left free but not with a larger optical zone. It may be possible that radial sutures have a permanent flattening effect when the sutures are left in place and keep their tensile strength.
