THE EFFECTS OF FULL CORRECTION VERSUS UNDER-CORRECTION ON THE PROGRESSION OF EARLY ONSET OF MYOPIA

Abstract

BACKGROUND

One of the most common eye conditions in the world today is myopia, with an especially sharp rise in early-onset instances in youngsters. Because early-onset myopia is firmly linked to faster axial elongation and a higher likelihood of developing high myopia and accompanying sight-threatening problems later in life, it is particularly concerning. Therefore, one of the top priorities in ophthalmic research is figuring out how to effectively limit its advancement. The role of refractive correction, specifically whether full correction or under-correction of myopia has a greater influence on delaying the progression of the disease, is one of the most contentious parts of managing myopia. It is crucial to critically assess the consequences of full vs. under-correction on myopia progression given the growing prevalence of early-onset myopia and the lack of agreement over the best corrective techniques. In order to inform evidence-based therapeutic management, this study intends to add to the body of knowledge by investigating how various correction strategies affect the rate of progression in children with early-onset myopia.

OBJECTIVE: To compare the effect of under-correction vs full correction on the progression of early-onset of myopia

METHODOLOGY: The study involved 40 myopic youngsters between the ages of 6-12. A completely corrected group (n = 20) and an under-corrected group (n = 20) were formed from the participants. Lenses with +0.50 D under-correction were recommended for the under-corrected group in order to provide a slight residual blur. At the start of the study and after a six-month follow up period, optometric exams were performed. Refractive error variations were measured to evaluate the progression of myopia.
