Purpose
[2]To evaluate the effects of eccentric fixation on keratometry readings and axial length during IOL Master measurements in adults in order to quantify the degree of fixation loss causing a clinically significant amount of incorrectly measured astigmatic error when using the IOL Master.
[3]Methods
[4]Subjects: 29 eyes from 17 volunteers recruited from Kresge Eye Institute residents and faculty. Age range 26 to 65 years, mean 38. Exclusion criteria: visual acuity <20/60, stereopsis >80 seconds of arc, monocular status, strabismus, history of strabismus surgery and/or patching, known corneal or macular disease.Measurements of keratometry and axial length were obtained with the IOL Master. Baseline measurements served as the control for each eye. Testing was performed 45 minutes after instillation of cycloplegic...
