Objectives: The objective was to assess the effect of fasting on the intraocular parameters. Materials and Methods: A total of 114 subjects enrolled in this study. The method included was the measurements of the keratometry readings, axial length, anterior chamber depth, lens thickness, vitreous thickness, and calculation of intraocular lens (IOL) power. These measurements were done twice at first while the patient is in the fasting state and second while the patient is in the fed state. Result: No change occurred in keratometry readings, lens thickness or vitreous thickness. The axial length decreased by 0.251 mm in the fasting state while the anterior chamber depth was 0.165 mm shorter. Furthermore, the power of IOL calculated by Sanders, Retzlaff, and Kraft formula was found to be increased by 1 D in the fasting state which was found to be statistically significant. Conclusion: Measuring the intraocular parameters for a patient who is in the fasting state will result in a shorter axial length and higher IOL power so care should be taken when measuring the intraocular parameters for a patient who is in the fasting state.
