What potential complication can arise from poorly measured IOL calculations?

Inaccurate visual outcomes post-surgery is a significant potential complication that can arise from poorly measured intraocular lens (IOL) calculations. Precise IOL power calculations are crucial for achieving the intended refractive target after cataract surgery or lens replacement. If these measurements are incorrect, it can lead to the wrong lens being implanted, which may result in refractive surprises such as residual myopia or hyperopia. This unexpected outcome may cause the patient to require glasses for distance or near vision after surgery, defeating the purpose of the procedure and leading to dissatisfaction with the overall surgical result.

Correct IOL calculations take into account factors like the length of the eye (axial length), curvature of the cornea, and other individual anatomical characteristics. Any errors in this data can directly influence the refractive outcome. As such, achieving accurate preoperative measurements and calculations is vital to ensure optimal visual results and overall patient satisfaction post-surgery.
