title: Same-day versus first-day review of intraocular pressure after uneventful phacoemulsification.
abstract: OBJECTIVE
  To compare the incidence and the spectrum of postoperative complications detected when the intraocular pressure (IOP) is reviewed 4 to 6 hours or the day after uneventful phacoemulsification cataract extraction and intraocular lens (IOL) implantation.
  
  
  METHODS
  Royal Free Hospital, London, United Kingdom.
  
  
  METHODS
  The study cohort consisted of 141 patients who had uneventful phacoemulsification and IOL implantation under regional (peribulbar/topical) or general anesthesia. Postoperative evaluation of the patients was performed by an ophthalmologist using a standard form at 4 to 6 hours or 24 hours.
  
  
  RESULTS
  The mean IOP at 4 to 6 hours and 24 hours was 22.85 mm Hg +/- 9.56 (SD) and 19.44 +/- 7.04 mm Hg, respectively. The IOP was more likely to be greater than 30 mm Hg when measured on the same day, resulting in a significantly higher intervention rate than on the first day (P =.037). The best corrected visual acuity was significantly better at 24 hours than at the same-day review (P <.001). There was no significant difference in the extent of anterior chamber activity, patient comfort, or state of the wound between the same- or next-day follow-up. All patients attended a follow-up appointment 3 weeks after surgery, had an IOP of 21 mm Hg or less, and were subsequently discharged.
  
  
  CONCLUSIONS
  The results indicate that moderate IOP spikes (<40 mm Hg) can be left untreated if they are not associated with corneal edema or patient discomfort as they decline spontaneously. Before they are discharged, patients with compromised optic discs or predisposed to retinal or optic nerve pathology should be carefully evaluated the day after surgery to treat IOP elevations.
