title: Laser in situ keratomileusis and diode thermal keratoplasty for correction of hyperopia from +5.00 to +10.00 diopters.
abstract: OBJECTIVE
  To evaluate the effects and safety of laser in situ keratomileusis (LASIK) and diode thermal keratoplasty (DTK) for correction of moderate to high hyperopia (+5.00 to +10.00 D).
  
  
  METHODS
  This prospective study included 30 eyes of 15 patients who had LASIK-DTK bioptics. The median age of the patients was 50.5 years. LASIK was performed using a Nidek EC-5000 excimer laser system and DTK by a Prolaser DTK laser, 2 months after LASIK. Follow-up ranged from 9 to 12 months (mean, 10.5 mo).
  
  
  RESULTS
  The mean preoperative spherical equivalent refraction was +8.25 +/- 0.25 D and mean postoperative was +1.00 +/- 0.50 D. The preoperative best spectacle-corrected visual acuity (BSCVA) was < or = 20/40 in 10 eyes and > or = 20/25 in 20 eyes. Postoperatively, BSCVA was < or = 20/40 in 8 eyes and > or = 20/25 in 22 eyes. No significant intra- or postoperative complications occurred.
  
  
  CONCLUSIONS
  LASIK-DTK bioptics for correction of moderate to high hyperopia (+5.00 to +10.00 D) was safe and effective. In this method, two different ablative and non-ablative laser systems were used to compensate for regression, which is the most important concern in the correction of hyperopia.
