STAGES OF SUBJECTIVE REFRACTION EXAMINATION OF MYOPIA PRESBYOPIA PATIENTS AT OPTIK PRO SEMARANG

mochammad Kholil

Abstract


A person's inability to see distant objects clearly can occur for several reasons, including myopia. Based on the static concept, myopia is a disorder where the rays entering the eyeball are refracted by the refractive medium in front of the retina. One rehabilitation for myopia sufferers is using glasses as a vision aid. The aim of this study is to find out how the subjective refraction examination procedure is in Presbyopia sufferers with Myopia refraction status. This knowledge is very important to understand, because it is through subjective refraction examination that the size of the glasses is determined so that they can be used as a vision aid. This research was carried out using descriptive methods through a case study approach. The population in this study was subjective refraction examinations recorded in the period 2 - 31 December 2023 at optic pro Semarang. The sample from this study was one of the sufferers who was quite communicative and could represent the entire sample.
The research results showed that in the period 2 - 31 December 2023, there were 16 presbyopia sufferers with myopic refraction status or 17.5% of the total sufferers who received refraction services at optic pro Semarang. In this case, the patient must wear bifocal glasses so that the patient can see far and near clearly.
When determining the size of reading glasses, patients should pay attention to a comfortable reading distance. If the sufferer wants to correct far and near vision with one pair of glasses, it is recommended to use bifocal glasses, kryptok, flattop, or progressive lenses.
