Abstract

prospective study of 32 eyes, undergoing laser refractive surgery, was performed. Routine complete pre-operative evaluation was done. A new device (Ocular Cyclotorsion Measurement Device, OCMD® has been used to evaluate the rotation of the eye from the sitting to the supine position. 68.75 % (n = 22) of the eyes had no rotation with the position changes. 15 % (n = 5) had inward rotation and 15% (n = 5) had outward rotation. The range of rotation varied from 5 degrees to 10 degrees. There was no correlation between the degree of nearsightedness or astigmatism with the degree of rotation (R2 =0.037). The rotation of the eye from the sitting to supine position can cause misalignment of the axis of treatment especially cases with astigmatism. Care should be taken when treating cases with high astigmatism.
