Vision-Specific Quality of Life: Laser-Assisted in situ Keratomileusis Versus Overnight Contact Lens Wear.

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.

Conclusions: Myopic subjects analyzed in this study reported better vision-related quality of life when they were corrected with continuous wear silicone-hydrogel lenses. The average score reached by CRT was similar to emmetropes, which showed the main disadvantage in worry subscale. The patients who underwent LASIK had the lowest valuation, highlighting the decreases in scores of diurnal fluctuations, glare, and especially in expectations and worry subscales, due to the first and second subscales, but especially to the false expectations created about treatment.
