title: Lens Extraction for Management of Coexisting Cataract and Post-filtering Surgery Ocular Hypotony.
abstract: OBJECTIVE
  To evaluate the safety and efficacy of phacoemulsification for management of post-filtering ocular hypotony.
  
  
  METHODS
  This prospective interventional case series study recruited 21 consecutive patients with an established diagnosis of ocular hypotony with or without maculopathy. Clear corneal incision phacoemulsification was done for all patients. Nineteen cases that completed a follow-up of at least 6 months were considered for final analysis.
  
  
  RESULTS
  Mean baseline intraocular pressure (IOP) was 2.95 ± 1.43 mm Hg, which increased to 8.84 ± 4.67 mm Hg at 6 months (P < 0.001). Hypotony was resolved in 13 cases (68%) at 6 months while 6 cases (32%) showed persistent hypotony at this time point. Postoperative IOP change at all follow-up time points was not correlated with patient age, time interval between filtering surgery and phacoemulsification, baseline IOP, baseline anterior chamber depth and IOP on the first postoperative day. Three cases (16%) showed filtering bleb failure with dramatic IOP rise around the first postoperative month and required glaucoma medication for IOP control. No significant intra- or postoperative complications were noted.
  
  
  CONCLUSIONS
  Cataract surgery alone seems promising in resolving hypotony in patients with post-filtering ocular hypotony, and can be considered as an effective treatment modality before proceeding to more complicated procedures.
