| Title | Functional visual outcomes of cataract surgery in patients with 20/20 or better preoperative visual acuity. | | Author(s) | Amesbury EC, Grossberg AL, Hong DM, Miller KM | | Institution | Department of Ophthalmology, David Geffen School of Medicine at UCLA and the Jules Stein Eye Institute, Los Angeles, California 90095-7002, USA. | | Source | J Cataract Refract Surg 2009 Sep; 35(9):1505-8. | | Abstract | PURPOSE: To measure the visual outcomes after cataract surgery in patients with 20/20 or better preoperative visual acuity.
SETTING: University-based cataract referral practice.
METHODS: In this retrospective case review, 2 groups of patients with a corrected distance visual acuity (CDVA) of 20/20 or better in both eyes before cataract surgery were identified. Patients in the first group had a cataract in 1 eye and an intraocular lens (IOL) in the other eye. Patients in the second group had cataracts in both eyes. Each patient completed a Visual Function 14 (VF-14) questionnaire before and after cataract surgery. Changes in VF-14 scores were analyzed.
RESULTS: The VF-14 scores improved significantly after cataract surgery in both groups. Patients with cataract in 1 eye and an IOL in the other eye before surgery (n = 28) had a mean improvement of 12.2 in the VF-14 score (P = .029). Patients with cataract in both eyes (n = 31) had a mean improvement of 14.5 in the VF-14 score (P<.0001).
CONCLUSIONS: The functional vision of patients with 20/20 or better preoperative CDVA improved significantly after cataract surgery. This finding shows that arbitrary CDVA thresholds of worse than 20/20 cannot always be used to determine who will benefit from cataract surgery. | | Language | eng | | Pub Type(s) | Journal Article
