AB  - PURPOSE: To study the biometric modifications of the eyeball during suction in 
      Laser assisted in Situ Keratomileusis (LASIK). METHODS: Observational and 
      cross-sectional study. We studied 43 patients who underwent surgery for myopia 
      and myopic astigmatism. Mean age was 38.3 +/- 11.5 years, and 19 were female 
      (44.2%). Conventional LASIK surgery with a manual microkeratome was performed. 
      Before and during the suction maneuvre the following parameters were measured 
      using an 11 Mhz biometric probe: aqueous depth (AQD), lens thickness (LT), 
      vitreous cavity length (VCL) and axial length (AXL). Paired t-test was used to 
      compare the biometric measurements before and during suction. RESULTS: The mean 
      spherical equivalent refractive error was -4.5 +/- 2.3 diopters. During suction, 
      the AQD did not change significantly (p = 0.231). However, AXL and VCL increased 
      by 0.12 mm and 0.22 mm respectively (p = 0.039 and <0.01) and LT decreased by 
      0.20 mm (p < 0.01). AXL increased in 42% of the eyes and decreased in 16%, VCL 
      increased in 70% of the eyes and decreased in 9%, and the LT was reduced in 67% 
      of the eyes. CONCLUSIONS: Suction maneuvres during LASIK surgery produce changes 
      of little magnitude in the eye globe, mainly a decrease in LT and an increase in 
      VCL and AXL. Therefore, these modifications are expected to produce minimal 
      anatomic alterations.
