Abstract

The amplitude of accommodation (AA) reflects the eye’s ability to adjust its refractive power to focus on near objects and is influenced by age, sex, and refractive status. This descriptive observational study aimed to evaluate the amplitude of accommodation among patients with refractive errors at Makassar Eye Hospital in 2024. A total of 100 participants aged 20–68 years were selected using purposive sampling, resulting in 200 eyes examined. AA was measured monocularly using the push-up method with a Royal Air Force (RAF) Rule, and calculated using the formula AA = 100/NPA (in cm). The overall mean AA was 7.0 ± 0.01 diopters (D). Higher mean AA values were found in the 28–36 age group (9.3 ± 0.06 D) and in female patients (7.4 ± 0.00 D), while the lowest AA was observed in hyperopic individuals (5.7 ± 0.39 D). These findings indicate that AA varies across age groups, sexes, and refractive types, and underscore the need for accommodative function evaluation as part of routine refractive assessments in optometric practice.

Abstract

This study aims to determine the relationship between laptop use and the degree of Near Point Convergence (NPC) among employees at the Makassar Eye Hospital in 2024 using the Royal Air Force Rule (RAF Rule) tool. The research uses a descriptive method with a cross-sectional approach involving 36 participants selected through purposive sampling. Data were analyzed using univariate and bivariate statistical tests. Results showed no significant relationship between NPC and age (p = 0.149) or gender (p = 0.480). However, a significant relationship was found between screen time and NPC (p = 0.035), suggesting that prolonged laptop use can negatively affect convergence ability. These findings underscore the need for awareness and preventive strategies among individuals with extended screen exposure to minimize risks of convergence insufficiency.
