title: Photorefractive keratectomy on purely refractive accommodative esotropia.
abstract: BACKGROUND
  Results on refractive keratectomy of the treatment of young patients with purely refractive accommodative esotropia.
  
  
  OBJECTIVE
  Evaluating the results of refractive keratectomy (PRK) on the treatment of young patients with purely refractive accommodative esotropia.
  
  
  METHODS
  This prospective study comprised patients with purely accommodative hyperopic esotropia. Patients underwent a complete ophthalmologic examination that included pre-operative and post-operative best corrected visual acuity (BCVA) and uncorrected visual acuity (UCVA) (at 3, 12, and 24 months), alignment and sensory outcomes; keratometry, pachymetry, and corneal topography.
  
  
  METHODS
  paired T-student.
  
  
  RESULTS
  Twenty eyes of 10 patients (mean age 21.5 years) were treated. The pre-operative mean UCVA was 0.70 logMAR (SD ± 0.177) and 0.02 logMAR (SD ± 0.029) two years later. The pre-operative BCVA was 0.02 logMAR (SD ± 0.037) and 0.01 (SD ± 0.026) two years later. The mean spherical equivalent (SE) in cyclopegia was + 3.92 D (range: +2.75 to +5.00 D; SD = 0.62) pre-operatively, -0.69 D (range -0.5 to -1) at three months and 0 D (range: -0.25 to 0.25) at one and two years later. After surgery, all patients were orthophoric without correction and stereopsis was unaffected by PRK.
  
  
  CONCLUSIONS
  A two-year follow-up showed that photorefractive keratectomy was an effective treatment for esotropia associated with mild to moderate hyperopia in young adults with purely refractive accommodative esotropia.
