title: Photorefractive keratectomy in megalophthalmos anterior.
abstract: OBJECTIVE
  To evaluate the results of photorefractive keratectomy (PRK) for the correction of myopia and myopic astigmatism in megalophthalmos anterior.
  
  
  METHODS
  Four eyes of two brothers with megalophthalmos anterior were treated with PRK. In patient 1, best spectacle-corrected visual acuity (BSCVA) was 20/20 in both eyes with a refraction of -4.50 -4.50 x 180 degrees in the right eye and -3.75 -3.00 x 175 degrees in the left eye. In patient 2, BSCVA was 20/25 in both eyes with a refraction of -4.25 x 166 degrees in the right eye and +0.50 -4.00 x 175 degrees in the left eye.
  
  
  RESULTS
  Topographic map, slit-lamp, ultrasound biomicroscopy, and postoperative course (no progression), supported with vectorial analysis, demonstrated megalophthalmos anterior. During 24-month follow-up, mild haze was observed and BSCVA was maintained.
  
  
  CONCLUSIONS
  Myopia and astigmatism are often observed in this type of nonprogressive corneal dysgenesis. Based on this fact and our results, we recommend PRK in cases of megalophthalmos anterior.
