16. Prediction of Refractive Stabilization after Cataract Surgery…Is it Possible?

The goals of modern cataract surgery include restoration of vision as completely and rapidly as possible while minimizing complications. At the same time, postoperative refractive errors should be negligible. Although the refractive outcome is not the unique measure to determine the success, low refractive errors with rapid stabilization improve patient satisfaction and quality of life. However, a pronounced, transient postoperative corneal swelling lasting approximately two weeks is sometimes noted after phacoemulsification surgery. Evaluation of postoperative corneal swelling is easily done with ultrasonic or optical pachymetry and is important because swelling can cause refractive changes that limit fast visual rehabilitation. There are few studies evaluating stabilization of refraction after cataract surgery with minimal changes after two weeks. Most of those studies were retrospective and evaluated the spherical equivalent, but it is more accurate to distinguish between spherical and cylindrical refraction. In a prospective study, we found that refraction (spherical and cylindrical component) was stabilized one week after surgery.
