title: Super vision: dream or reality.
abstract: OBJECTIVE
  To present and evaluate the early clinical experience of laser in situ keratomileusis (LASIK) using the custom guided corneal ablation system by NIDEK, which includes an OPD-Scan, Final Fit program, and Nidek Multipoint EC-5000 excimer laser.
  
  
  METHODS
  The OPD-Scan diagnostic system containing a scanning slit refractometer using skiascopic technology with simultaneous Placido disc corneal topography is described. The Final Fit program that converts the refractive error and topography data into custom algorithms to couple with the Nidek EC-5000 Multipoint excimer laser is explained. Thirty-eight cases of LASIK using the Nidek MK-2000 microkeratome and the Nidek Multipoint excimer laser with custom and conventional treatments are presented. Eyes were divided into two groups: LASIK custom group and LASIK conventional group.
  
  
  RESULTS
  Predictability and attempted correction were similar in both groups. One month after surgery, all eyes were between +/-1 line of visual acuity. In the custom LASIK group there was a gain of one line in 50% and two lines of visual acuity in 25% of patients at 1 month after surgery. In the conventional LASIK group there was no gain of lines of visual acuity at 1 month. In the comparative group (one eye custom LASIK and the other eye conventional LASIK) there was data available for six patients (75%). At one month, all patients preferred the vision in their custom LASIK-treated eye.
  
  
  CONCLUSIONS
  The Nidek LASIK custom and conventional treatments were safe and predictable. There was more accuracy, better visual acuity, and more subjective satisfaction in the custom LASIK custom treatment group.
