Abstract
CONTEXT
Evaluation of visual quality in soft and rigid gas-permeable contact lens wearers, with an emphasis on twilight vision.
PURPOSE
To assess the visual acuity and visual performance at dusk before and after soft and rigid gas-permeable contact lens (CL) correction in healthy subjects.
SETTINGS AND DESIGN
This prospective study was conducted in a tertiary eye-care center.
METHODS
Sixty eyes corrected with soft contact lenses (SCLs) and 30 eyes with rigid gas-permeable contact lenses (RGPCLs) were enrolled in this study. Patients underwent corrected distance visual acuity with spectacles (CDVAs), corrected distance visual acuity with contact lenses (CDVAcl), and twilight vision (TV) testing (Vista Vision Far-Pola, DMD MedTech charts). Parameters were evaluated before and after the CL fitting and repeated 3 months after the baseline visit.
STATISTICAL ANALYSIS USED
MedCalc for Windows, version 11.4 (MedCalc Software, Ostend, Belgium).
RESULTS
Rigid gas-permeable CL wear showed significant improvement in CDVAcl compared to wearing spectacles on both visits ( P = 0.0039 and P = 0.0003, respectively). TV with CLs was significantly better in both groups compared to the TV with spectacles at the baseline visit ( P = 0.0011 in SCL group; P = 0.0001 in RGPCL group), and at the follow-up visit, this significance was proven for the RGPCL group ( P = 0.001). Also, spectacle TV showed a significant improvement on the follow-up visit ( P = 0.0022 in SCL group; P = 0.0269 in RGPCL group).
CONCLUSION
Contact lens wear improves visual performance compared to spectacles. TV results showed superiority of CLs compared to the spectacles, without a statistical difference regarding the CL type.
