title: [Preliminary results of Artisan phakic intraocular lens implantation to correct myopia].
abstract: OBJECTIVE
  To observe the preliminary results based on the efficacy, stability and safety of Artisan anterior chamber intra-ocular lens for the correction of myopia in the first 6 months.
  
  
  METHODS
  A retrospective study of 18 patients (34 eyes) that received the implantation of Artisan anterior chamber intraocular lens for the correction of myopia was conducted. Best visual preoperative acuity, best visual postoperative acuity, dynamic preoperative and postoperative refraction, loss and improvement of lines of vision and complications were evaluated.
  
  
  RESULTS
  Eighteen patients (34 eyes) were included in this study. Fourteen patients were females (77.8%) and 4 were males. The mean age was 30 years (SD +/- 7.3), range from 21 to 46 years. They were followed up for an average of 8.5 months (SD +/- 3.6). The mean endothelial cell loss was 4.75% at 6 months follow-up. The average preoperative uncorrected visual acuity was 0.02 (20/800) range from 0.01 to 0.13. The average preoperative spherical equivalent was -13.25 D, range from -5.75 D to -19,75 D. On the last follow-up, uncorrected visual acuity was 0.64 (20/32), range from 0.33 to 1.00; the average spherical equivalent was -1.18 D (DP +/- 0.92) range from +0.25 to -3.0. Complications were observed in 1 case (3.4%) of our study, in one patient who had a dislocation of the lens after an ocular trauma.
  
  
  CONCLUSIONS
  The use of Artisan anterior chamber intraocular lens in phakic eyes for the correction of myopia was safe, effective and predictable. However, a larger prospective study with a higher number of cases and longer follow-up is necessary to determine long-term safety of the lens.
