title: [Phacoemulsification with silicone foldable intraocular lens implantation through a small incision in glaucomatous eyes after filtering surgery].
abstract: OBJECTIVE
  To investigate the method of cataract extraction in eyes that had undergone glaucoma filtering surgery and its effects on filtering bleb.
  
  
  METHODS
  Phacoemulsification with posterior chamber intraocular lens implantation was performed on 262 eyes with a preexisting filtration bleb, in which at the temporal clear cornea a lateral or inferior lateral limbal incision was selected, the pupil sphincter was cut and the iris was sewed for the small and fixed pupil.
  
  
  RESULTS
  The postoperative visual acuity of all patients improved in different degrees, with >or= 0.5 in 74.0% in the first month. The postoperative IOP increased by 3.08 mmHg. The functional filtering bleb was not apparently cicatrized.
  
  
  CONCLUSIONS
  Glaucomatous eyes with cataract after filtering operation can rehabilitate their visual acuity and maintain the functional filtering bleb by phacoemulsification with foldable intraocular lens implantation through a temporal clear corneal incision or lateral scleral pocket incision. Theoretically, the effect of a transparent corneal incision on filtering bleb is less than that of a scleral pocket incision.
