title: [Long term results of phakic 6 refractive implantation for myopia correction].
abstract: OBJECTIVE
  To evaluate the safety and the long term results of anterior chamber phakic lens, Phakic 6 Refractive, for myopia correction.
  
  
  METHODS
  In this retrospective study we reviewed the charts of 35 myopic patients (62 eyes) who had implantation of anterior chamber phakic lenses (Phakic 6 Refractive, Ophthalmic Innovations International, California, USA) for correction of myopia. The mean age of patients was 26 years (18 to 45 years). The mean spherical refraction was -9.9 (-4 to -18 D). The best corrected distant visual acuity (BCDVA) was 0.92 (1.2 to 0.3) before surgery. The mean follow-up was 8 years (4 to 10). The mean endothelial cell count was 2481 cells/mm2 and the mean pachymetry was 540 μm before surgery. In those patients who needed a second surgical intervention (explantation or lens reposition) the last follow-up visit is the visit before the lens explantation or reposition. The same surgeon (P. R.) performed all surgeries and used the same technique in each surgery.
  
  
  RESULTS
  On the final follow up visit the BCDVA was in the mean 1.02 (1.5 to 0.5). The spherical refraction was in the mean - 0.53 D (-3.0 to +1.0). We noticed a 16% decrease in the mean number of corneal endothelial cells, and no change in the pachymetry values. We had to explant the lenses in 7 eyes (12 %) because of the decreased endothelial cells count. 2 eyes (3.0 %, 1 patient) had to receive treatment for glaucoma, 4 eyes (6.5 %) had to have the artificial lens repositioned, 1 patient had to have photocoagulation therapy for a retinal tear. 93 % of the study eyes had stable refraction during the study period. There was a 10 % increase in the average BCDVA, and there was a 95 % improvement of the original refractive error.
  
  
  CONCLUSIONS
  In selected cases, the implantation of Phakic 6 Refractive anterior chamber lens is a viable option despite it is currently largely abandoned. Key words: Phakic 6 Refractive implantation, myopia correction.
