Paper Abstract

Until recently, surgical correction of hyperopia was subject to nearly total regression regardless of the method used. Laser thermokeratoplasty (LTK) with the holmium:YAG laser (Sunrise Technologies' Corneal Shaping System) is able to correct hyperopia in the range of + 1.0 to + 3.0 diopters. Up to eight spots with a spot size of 650 micrometers can be delivered simultaneously. According to the amount of hyperopia to be corrected, eight or sixteen spots are administered with respective pattern diameters of six or six and seven mm. The energy density used is 8.5 J/cm2 per spot. Most of the regression occurs within the first month. In the 30 eyes with a follow-up of 6 months patient satisfaction rate is high and complications are minimal.
