Rigid Gas Permeable Contact Lens Can Reduce the Progression of Myopia?

Introduction: Myopia is a global issue though prevalence varies from country to country but a huge number of people suffer from complications of myopia. It is a multifactorial disorder and there is no know way to prevent the development of myopia, but lots of research is ongoing to prevent the progression of myopia and RGP contact lens is one the debatable issue to halt the progression. Methods: It was a prospective analytic study done at Green Eye Hospital, Dhanmondi, Dhaka, Bangladesh. The study was conducted from January 2018 to December 2019 total two-year period. There were 160 patient enroll in the study, they were divided into two groups. In Group: A, 80 patients those who were using RGP contact lens and the patient were selected by non-random purposive sampling method, on the other hand, group: B had 80 patients those were selected by quota sampling to match with the group: A patient by demographically. Data were collected thrice, first at entry point, second after one-year and third after two-year. Results: Data was normally distributed so we did Independent “t” test, chi-squared and ANOVA with the help of Statistical Package for the Social Sciences (SPSS) version 22. All the demographic variable was non-significant. Mean and SD of refractive error at entry point was 3.6813 ± 1.9172 and 3.7281 ± 1.9658 respectively (P: 0.8788 95% CI -0.6532 to 0.5595). After two-year it was 3.9031 ± 2.3076 and 5.0031 ± 2.4673 respectively (P: 0.0041 CI -1.845992 to -0.354008). Conclusion: RGP contact lens can reduce the progression of myopia. And it is the time to increase optometric service in country-wide.
