title: [Comparison between one-site and two-site incision in phacotrabeculectomy].
abstract: OBJECTIVE
  To compare the effect of one-site and two-site incision in phacotrabeculectomy in terms of intraocular pressure control.
  
  
  METHODS
  Forty-five cases (47 eyes) of phacotrabeculectomy were retrospectively reviewed. The nuclei of all the cases were not harder than Grade III. One-site approach was performed on 29 eyes, and two-site approach, on 18 eyes. The effects of intraocular pressure control were compared between the two groups.
  
  
  RESULTS
  Follow-up was 13-30 months (mean 18.9 months). The postoperative intraocular pressure in the one-site group was (16.81 +/- 4.56) mm Hg (1 mm Hg = 0.133 kPa), (15.32 +/- 6.67) mm Hg lower than that before surgery. And the postoperative intraocular pressure in the two-site group was (17.63 +/- 4.60) mm Hg, (16.42 +/- 6.98) mm Hg lower than that before surgery. There was no significant difference between the two groups relative to the effect of intraocular pressure control (t = 1.44, P > 0.05).
  
  
  CONCLUSIONS
  Phacotrabeculectomy, either with one-site approach or with two-site approach, can provide good intraocular pressure control. The effects are similar between the two approaches in soft cataract patients.
