[Current limitations of radial keratotomy].
The so-called R.K. classic technique gives good results for myopias under 5 diopters. We have performed different modifications of the technique for the 8 incisions--optical zone 3 mm R.K. 8 incisions--O.Z. 3 mm. Downhill incision direction or "American technique" incisions (from the O.Z. towards the limbus). 8 incisions--O.Z. 3 mm + a deepening of 20 microns from a 6 mm O.Z. Repeat operations (Stan Franks Backcutting technique or addition of incisions). 8 incisions--O.Z. 3 mm. Uphill incision direction or "Russian technique" (from the limbus towards the optical zone). This study was carried out with 134 R.K. and shows that we get best results for myopias between 5 to 7 diopters, with the last technique (Uphill incision direction).
