Resumen:
OBJECTIVES:
To compare the visual-related quality of life in myopic subjects with different refractive treatments such as continuous wear of silicone-hydrogel contact lenses (CL), corneal refractive therapy (CRT), and laser-assisted in situ keratomileusis (LASIK).
METHODS:
The National Eye Institute Refractive Error Quality of Life Instrument (NEI RQL-42) questionnaire was administered to 96 subjects with a mean age of 30.0±7.9 years. There were 72 myopic subjects with a mean spherical equivalent of -2.74±0.98 D (-5.50 to -1.25 D). Subjects were corrected with LASIK (n=24), Paragon CRT orthokeratology lenses (n=24), and lotrafilcon A silicone-hydrogel CL under continuous wear (n=24). The NEI RQL-42 survey was used to compare differences between groups as well as with an emmetropic group (n=24).
RESULTS:
After 1 year of treatment, significant differences were found among all groups in the subscales glare (P=0.017), symptoms (P=0.016), dependence on correction (P<0.001), and worry (P<0.001). The mean difference compared with emmetropes were -5.5% (P=0.063) for LASIK patients, -2.0% (P=0.212) for orthokeratology subjects, and +1.6% (P=0.934) for the silicone-hydrogel CL group.
