The influence of environmental factors on contact lens fitting in Sweden (English)
Abstract [sv]

Syfte: Syftet med studien var att undersöka om omgivande miljöfaktorer samt skillnader i latitud har en påverkan på hur kontaktlinser tillpassas i olika delar av Sverige.

Metod: Enkäter delades ut till optiker i området kring Östersund samt Göteborg där de fick fylla i sina tio nästkommande ny- och retillpassningar av kontaktlinser med information kring linsmaterial samt bytesfrekvens. Historiska meteorologiska miljöfaktorer extraherades från Sveriges Meteorologiska och Hydrologiska Institut (SMHI) gällande medeltemperatur samt luftfuktighet. Sedan sammanställdes och analyserades all data.

Resultat: Totalt deltog 28 optiker, vilket resulterade i 192 tillpassade kontaktlinser. Det fanns ingen statistiskt signifikant skillnad i relativ luftfuktighet mellan de två områdena (U = 687,500, p = 0,281). Det fanns däremot en statistiskt signifikant skillnad i temperatur under årets första fyra månader (t(86) = 7,968, p <0,001), där temperaturen i genomsnitt var högre i Göteborg. En statistiskt signifikant skillnad fanns även när det gällde bytesfrekvens utifrån material på mjuka kontaktlinser mellan de undersökta områdena, X2(4, N = 178) = 13,676, p = 0,008, där optikerna i Östersund tillpassade en högre andel endagslinser.

Slutsats: Det tillpassas mjuka kontaktlinser för dagsbruk i större utsträckning i Östersund som har kallare temperatur och högre latitud än Göteborg.

Abstract [en]

Aim: The aim of this study was to investigate if environmental factors and differences in latitude affect how contact lenses are prescribed in different parts of Sweden.

Methods: Surveys were distributed to optometrists in the areas around Östersund and Gothenburg, where they filled out information about lens material and replacement frequency for their next ten contact lens fits (new or refits). Historical meteorological environmental factors regarding temperature and relative humidity were extracted from SMHI, the Swedish Meteorological and Hydrological Institute. The data was then compiled and analyzed.

Results: A total of 28 optometrists participated in this study, which resulted in 192 contact lens fits. There was no statistically significant difference in relative humidity between the two areas (U = 687,500, p = 0,281). However, there were statistically significant differences regarding the temperature for the first four months of the year (t(86) = 7,968, p <0,001), where the average temperature was higher in Gothenburg. A statistical significant difference was also found regarding the replacement frequency based on lens material on soft contact lenses between the examined areas, X2(4, N = 178) = 13,676, p = 0,008) where optometrists in Östersund prescribed a higher percentage of daily disposable contact lenses.

Conclusion: Daily disposable contact lenses were prescribed to a greater extent in Östersund that has a colder temperature and higher latitude compared to Gothenburg.
