title: [The choice of intraocular lens before cataract extraction for cases with high myopia].
abstract: OBJECTIVE
  To study the choice of diopter and size of optical portion of intraocular lens (IOL) before cataract extraction for cases with high myopia.
  
  
  METHODS
  Extracapsular cataract extraction (ECCE) or phacoemulsification with IOL implantation was performed on 60 cases (94 eyes) with high myopia (axial length > 26mm). The posterior chamber IOL selected and inserted was the one with the diopter and size of the optical portion suitable for the recipient to have a postoperative low myopia and easy to be examined with an ophthalmoscope.
  
  
  RESULTS
  The postoperative eyes were of low myopia, -2.07 +/- 1.95 D. The larger size of optical portion was more suitable for ocular fundus examination. Great care was taken for phacoemulsification for cataractous nucleus below III grade.
  
  
  CONCLUSIONS
  For patients with axial myopia, the IOL implanted should create low myopia postoperatively. Larger optic size is better for fundus examination. Phacoemulsification can produce less astigmatism and damage, but the indication must be controlled strictly.
