Purpose
To comprehensively characterize the quality of vision (QV) in an otherwise healthy population undergoing bilateral consecutive cataract surgery with the implantation of a pure monofocal intraocular lens (IOL), and to graphically illustrate distance QV.
Setting
This study was held at Ophthalmology Department of University Hospital of Coimbra, Unidade Local de Saúde de Coimbra, EPE, Portugal.
Methods
An observational cross-sectional study was designed, involving otherwise healthy patients aged between 50 to 79 years undergoing consecutive bilateral cataract surgery with the implantation of a pure monofocal acrylic foldable single-piece IOL (Acrysof SN60AT®) in the capsular bag. All patients were assessed at the 3rd postoperative month for distance and near visual acuity (VA) with and without correction; sphero-cylindrical refraction; reading speed; contrast sensitivity function (CSF) with and without glare; negative dysphotopsia questionnaire; corneal topography/tomography; aberrometry; and pupillometry. Catquest 9SF and Quality of Vision (QoV) questionnaires were also carried out.
Results
Fifty-two eyes (n=52) from 26 patients with mean age of 68 years (+/- 6.68) were included. Mean uncorrected distance VA was 0.01 (+/- 0.04) logMAR and best corrected VA was 0.00 (+/- 0.04). The mean sphere value was -0.140 (+/- 0.35) diopters (D), while the cylinder was -0.364 (+/- 0.55) D. The average reading speed was 110.42 words/minute. The CSF showed a descendent curve for higher spatial frequencies and was lower with glare. Persistent negative dysphotopsia was present in 1.92 % of the patients. Catquest-9SF mean was 95.46% (± 7.24) and QoV mean score was 4.48 (± 5.65) points. A radar graph showing average scores with 95 % confidence intervals across the multiple variables assessed was produced demonstrating a wide panorama of QV.
Conclusions
This study characterizes the overall outcomes of QV in standard bilateral cataract surgery, demonstrating very high patient satisfaction and low levels of dysphotopsia with a monofocal lens. Objective characterization of the QV is achievable through a comprehensive evaluation, aiding in the interpretation of patient satisfaction and prediction of future results. Graphic plotting of QV facilitates the interpretation of overall visual function, the comparisons between various types of IOLs and different stages in patients' conditions.
