title: Central anterior chamber depth changes after prophylactic laser iridotomy.
abstract: OBJECTIVE
  To evaluate the effect of laser peripheral iridotomy (LPI) on biometric parameters including central anterior chamber depth (CACD) in primary angle closure suspect eyes.
  
  
  METHODS
  Eyes classified as primary angle closure suspect were enrolled in this interventional case series. Biometry with Lenstar (Haag-Streit AG, Koeniz, Switzerland) was performed before LPI and 6 weeks afterward. Central anterior chamber depth, lens thickness, axial length, and central corneal thickness were measured before and after the intervention.
  
  
  RESULTS
  Forty eyes of 40 patients with mean age of 56.5 ± 5.5 years were studied. Mean central anterior chamber depth was 2.07 ± 0.21 mm before and 2.08 ± 0.19 mm after LPI (p = 0.8). There was no significant change in lens thickness, axial length, and central corneal thickness after LPI.
  
  
  CONCLUSIONS
  Central anterior chamber depth "measured by Lenstar" does not change after LPI in primary angle closure suspect eyes.
