Derajat Miopia Berhubungan dengan Ketebalan Kornea Sentral pada Usia 18-40 Tahun

Abstract

Background
The central corneal thickness (CCT) is important in assessing the cornea’s condition and correlates
with refractive errors in which myopic eyes have the thinnest central cornea. Based on the 2018
Riskesdas, 2,133,017 people suffer from severe low vision, of which 42% were connected to refractive
errors. One of the treatments for myopia is to perform LASIK surgery, but complications may occur
during its process. One of the risk factors for post-LASIK complications is a CCT of less than 500
microns. This study aimed to assess the association between the degree of myopia and CCT at 18-40
years old.

Methods
This study was a cross-sectional design with data taken from 124 medical records from the Gading
Laser Eye Center with subjects aged 18-40 years consisting of 88 males and 36 females. Variables
collected were initials, age, gender, CCT, and degree of myopia. Data analysis was carried out using
the Chi-Square test with a significance level of p<0.05.

Results
The age category was 18-28 (87.9%), dominated by males (71.0%). Most degrees of myopia were mild
(48.4%), and CCT was dominated by thinning corneas (63.7%). Data analysis based on the Chi-Square
test regarding the degree of myopia and CCT showed a significant association (p=0.001).

Conclusions
This study showed an association between the degree of myopia and CCT at the age of 18-40 years.
