Using a smartphone app in the measurement of posture-related pupil center shift on centration during corneal refractive surgery by Wenbo Cheng, Li Li, Gang Luo, Yan Wang

“…Moreover, pupil constriction was observed when the body position changed from seated to supine position (p < 0.001, OD 0.64 ± 0.57 mm, OS 0.63 ± 0.58 mm).Conclusion: Posture-related pupil center shift may be larger than the error tolerance of centration in corneal refractive surgery, which might be difficult to measure by the existing instruments. An accessible application is necessary for evaluating the shift of pupil center and guiding centration during the surgery.…”
