[Application of wavefront aberration technique in the study of phakic and pseudophakic eyes]

Modern cataract surgery is routinely combined with the implantation of an intraocular lens (IOL). Although surgical technique as well as IOL materials and designs have been improved dramatically, the problems related postoperative visual acuity still occur, such as glare disability, low visual acuity at night, and so on. Wavefront aberration technique can be used to help us revealing the real reasons of such postoperative visual problems. We reviewed the relative study outcome of the application of wavefront aberration technique in phakic eyes, and summarized the current opinions on the study of pseudophakic eyes.
