Abstract

Astigmatismus Myopicus merupakan suatu keadaan dimana sinar-sinar sejajar yang memasuki bola mata dibiaskan oleh media refrakta pada dua titik yang terpisah. Koreksi visus monokuler dengan metode fogging merupakan salah satu fase dalam pemeriksaan refraksi subyektif. Penelitian ini bertujuan untuk mengetahui bagaimana cara melakukan pemeriksaan refraksi subyektif pada penderita Astigmatismus Myopicus dengan metode fogging. Jenis penelitian yang digunakan adalah deskriptif dan pendekatan yang digunakan dalam penelitian bersifat cross sectional. Hasil penelitian di Optik Pro Ungaran menunjukkan bahwa pada periode 01-30 April 2023 ada total sebanyak 45 orang pasien Astigmatismus Myopicus Compositus dan Astigmatismus Myopicus Simplex, yang terdiri dari 18 orang (40%) pasien laki-laki dan 27 orang (60%) pasien perempuan yang diperiksa. Dari 45 pasien tersebut, pasien Astigmatismus Myopicus Compositus sebanyak 34 orang (75,56%), yang terdiri dari 12 (26,67%) pasien laki-laki dan 22 (48,89%) pasien perempuan, sedangkan pasien Astigmatismus Myopicus Simplex sebanyak 11 orang (24,44%), yang terdiri dari 6 (13,33%) pasien laki-laki dan 5 (11,11%) pasien perempuan.

Abstract

Gadget use among school-aged children has become a common phenomenon, both to support academic activities and as a means of entertainment. However, excessive use has the potential to negatively impact eye health, particularly in the development of refractive errors such as myopia and astigmatism. The aim was to analyze the relationship between the duration of gadget use and the emergence of refractive errors in students. The research approach used was quantitative with a survey method. Data were analyzed using a Chi-Square test to identify the relationship between the duration of gadget use (<4 hours and >4 hours per day) and the type of refractive error in 30 respondents. The test results showed a p-value of 0.063, which exceeds the 0.05 significance limit. This indicates no significant relationship between the duration of gadget use and refractive errors in students. However, a trend was found to increase cases of refractive errors in students who used gadgets for more than four hours per day. Therefore, further research with a larger sample size and consideration of environmental variables and other visual habits is strongly recommended. Overall, the results of this study confirm that short-duration gadget use has not shown a significant effect on refractive errors in elementary school students.
