title: What Factors Affect Intraocular Lens Power Calculation?
abstract: Obtaining precise postoperative target refraction is of utmost importance in today's modern cataract and refractive surgery. Emerging literature has linked postoperative surprises to corneal curvature, axial length, and estimation of the effective IOL position. As demonstrated in this case presentation, an inaccuracy in the axial length measurement can lead to a myopic surprise. A review of the literature has demonstrated that prevention of postoperative refractive surprises requires highly experienced nurses, technicians, and/ or biometrists to take meticulous measurements using biometry devices, and surgeons to re-evaluate these calculations prior to the surgery.
