title: A retrospective analysis of the first Yemeni experience on Artisan phakic intraocular lens for the treatment of moderate and high myopia.
abstract: OBJECTIVE
  To evaluate the outcome and safety of the iris-fixated Artisan phakic intraocular lens (PIOL) for the correction of moderate and high myopia.
  
  
  METHODS
  A retrospective non-controlled clinical study of the data of patients who underwent Artisan PIOLs between March 2006 and July 2008 was evaluated. Pre-operative examination included age, gender, refraction, uncorrected (UCVA) and best spectacle corrected (BSCVA) visual acuity, predictability and safety were analyzed. Post-operative time course ranged from 12 to 36 months.
  
  
  RESULTS
  An Artisan myopia lens was implanted in 62 eyes of 39 patients. The mean pre-operative spherical equivalent (SE) was -13.17 ± 5.62 D. The pre-operative myopia ranged from -4.5 to -24 D. Mean patient age was 25.44 ± 5.22 years. At last follow-up visit, residual SE was within ±1.00 D in 36 eyes (58.1%) and ±2.00 D in 56 eyes (90.3%). In the last visit UCVA was equal to or better than pre-operative BSCVA in 57 (91.9%) of the eyes. One eye (1.6%) lost one Snellen line, three eyes (4.8%) lost two or more Snellen lines and one eye lost vision (1.6%). Post-operative complications included anterior chamber reaction in one eye, rise in intraocular pressure in two eyes and retinal detachment in one eye.
  
  
  CONCLUSIONS
  When laser keratorefractive surgery is not an option, implantation of Artisan PIOL to correct moderate to high myopia results in a stable and good refractive result with few complications that must be kept in mind.
