Journal of cataract and refractive surgery
PURPOSE: To compare patient satisfaction, visual function, and spectacle independence in patients with crossed or conventional pseudophakic monovision.
SETTING: Department of Ophthalmology, Henry Ford Health System, Taylor, Michigan, USA.
DESIGN: Retrospective comparative cohort study.
METHODS: Cataract surgery patient records from June 1999 to December 2013 were reviewed. Crossed monovision patients were identified. Control conventional monovision cases were matched for age, sex, general health, personal lifestyle/main hobbies, preoperative refractive status, postoperative refractive status, uncorrected distance visual acuity, uncorrected near visual acuity, astigmatism level, and anisometropia level. A survey was mailed to participants, and results were independently analyzed.
RESULTS: The review comprised 7311 patient records. Forty-four crossed monovision patients were identified, and 30 of them were enrolled. Thirty matched pairs were surveyed. The mean anisometropia was 1.19 diopters (D) in the conventional and 1.12 D in the crossed monovision groups. No significant difference was identified for eye-hand coordination, eye-foot coordination, or sport-related depth perception, but satisfaction was slightly better in the crossed monovision group (P = .028). No significant difference was identified for 6 of 8 spectacle independence measures, but nighttime driving was a little easier for the crossed monovision group (P = .025). Seventy-seven percent of crossed and 50% of conventional monovision patients did not use glasses for intermediate distance activities (P = .037).
CONCLUSION: Crossed pseudophakic monovision appears to work as well as conventional pseudophakic monovision in terms of patient satisfaction and spectacle independence in patients with a mild degree of anisometropic pseudophakia.
