Abstract:
PURPOSE: In the present study, the dependence of intraocular pressure (IOP) on body position was compared between pseudophakic and phakic eyes after cataract surgery performed at least 3 months prior. METHODS: IOP was measured in 214 patients over 40 years of age who received cataract surgery at least 3 months prior. The present study included 104 patients who did not have any other ocular disease which could influence visual acuity or IOP. The IOP was measured in 4 different positions, sitting, supine, right decubitus, and left decubitus by a single skilled researcher using Icare tonometer. In addition, IOP was compared between the phakic and pseudophakic eyes, specifically, the dependent eye in the decubitus position. RESULTS: The comparison between the phakic and pseudophakic eyes in patients after cataract surgery in a single eye showed IOP was not different between the sitting and supine positions; however, in the decubitus position, IOP in the dependent eye was significantly higher than the non-dependent eye (p = 0.001). Additionally, regardless of lens status, IOP was significantly higher in the dependent eye than non-dependent eye. CONCLUSIONS: Both body position and lens status can affect IOP. After cataract surgery, regardless of lens status, IOP was higher in the dependent eye than non-dependent eye of patients in the decubitus position.
