Key Takeaways
- The number of individuals who will require cataract surgery after undergoing refractive surgery for correction of myopia or hyperopia (ie, post-refractive patients) is expected to increase.
- Accurate calculation of intraocular lens (IOL) power using conventional preoperative methods can be challenging in the post-refractive population because refractive surgery alters the shape of the central cornea as well as the posterior/anterior curvature ratio. Additionally, post-refractive patients may have higher expectations of spectacle independence and may find residual refractive errors after cataract surgery unacceptable.
- Optiwave Refractive Analysis (ORA) measures the refractive state of the eye during cataract surgery and can provide greater accuracy in IOL power calculation in the post-refractive population compared with preoperative calculation methods.
- Better accuracy of IOL power calculation using ORA can lead to the selection of the appropriate IOL and result in a greater percentage of patients achieving target refraction and can lead to freedom from spectacles.
