Objective functional visual outcomes of cataract surgery in patients with good preoperative visual acuity.

ABSTRACT: PurposeTo explore the objective functional visual outcomes of cataract surgery in patients with good preoperative visual acuity.MethodsWe enrolled 130 cataract patients whose best-corrected visual acuity (BCVA) was 20/40 or better preoperatively. Objective visual functions were evaluated with a KR-1W analyzer before and at 1 month after cataract surgery.ResultsThe nuclear (N), cortical (C), and N+C groups had very high preoperative ocular and internal total high-order aberrations (HOAs), coma, and abnormal spherical aberrations. At 1 month after cataract surgery, in addition to the remarkable increase of both uncorrected visual acuity and BCVA, both ocular and internal HOAs in the three groups decreased significantly after cataract surgery (all P<0.05).
