Compliance and acceptance of cylindrical reduction spectacles in new and old glasses users

Abstract

PURPOSE: To explain the compliance and acceptance of cylindrical reduction spectacles in new and old glasses users.

METHODS: A comparative cross-sectional study was performed in refraction clinic at Mayo Hospital Lahore to determine the compliance and acceptance of cylindrical reduction spectacles in new and old glasses users. The sample comprised of 34 Patients, females 23 (67.6%) and males 11 (32.35%) between 15 to 30 years of age. Astigmatism was classified into mild (up to 1.50D), moderate (1.50-3.00D) and severe (>3.00D). Each patient was singly observed after using cylindrical reduction spectacles for two weeks to find out its acceptance on the basis of asthenopic symptoms.

RESULTS: The acceptance and non-acceptance of cylindrical reduction spectacles were 44.11% and 55.88% respectively. The compliance of spectacles among acceptance was 61.11% and 38.89% among non-acceptance. The compliance of spectacles in the patients already using glasses was 65% and 35% in the patients wearing glasses for the first time. The acceptance in the patients already using glasses was 73% and 27% in the patients wearing glasses for the first time while non-acceptance in the patients already using glasses was 32% and 68% in the patients wearing glasses for the first time. The acceptance of spectacles in males was 53.33% and46.66% in females. Mild asthenopic symptoms at near distance were 81.35% while at far distance were 64.66%. These asthenopic symptoms were more in females, teenage and patients using glasses for the first time. p-value <0.05 was considered as significant.

CONCLUSION: Compliance and acceptance of cylindrical reduction spectacles was significantly higher in old glasses users as compared to the patients using glasses for the first time and was closely associated with gender, age and history of spectacles.
