Abstract
PURPOSE: 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.
