Abstract Details


Photorefractive keratectomy (PRK) has high demands from patients to give them best visual outcome (6/6). This study aims to explore preoperative factors that correlate to visual outcome of the patients after PRK.


Jogja Lasik Center at Yap Eye Hospital, Yogyakarta, Indonesia.


A one-year retrospective study in 2015 was conducted to explore factors that might give influences to visual outcome of PRK patients (n=976). The factors were age, gender, retinometry, Schirmer’s test results, central corneal thickness (CCT), operators, uncorrected visual acuity (UCVA), visual corrections, and best visual acuity (BCVA). Spearman correlation test was used for statistical analyses.


There were 96% of patients who were able to reach their best visual acuity (6/6) after PRK. Preoperative factors that have correlation with visual outcome after PRK are age, BCVA and visual corrections before PRK (degree of spheric and cylinder lens), as well as the operator who performs PRK (p< 0.05). Others factors are not correlated to patients’ visual outcome, such as gender, UCVA, retinometry, Schirmer’s test results, and CCT.


The age of the patients, best visual acuity before PRK, the degree of myopia and astigmatism can predict patients’ visual outcome after PRK. This study also found that the operator who performs PRK also have a role to influence the outcome, which might be interesting to investigate in the future.
