Correlation and Comparison of Anterior and Posterior Corneal Surface Parameters in Healthy Eyes: Doi: 10.36351/pjo.v38i3.1380

Purpose: To correlate and compare anterior and posterior corneal surface parameters like Kflat, Ksteep, Kavg, R1, R2, Ravg and astigmatism in healthy eyes. Study Design: Descriptive correlational study Place and Duration of Study: This study was conducted at Mayo Hospital, Lahore from June 2020 to Dec 2020.. Methods: This study included 176 subjects (86 males and 90 females) with mean age of 28.06±9.68 and 28.13±8.24 respectively. The data was collected through non-random convenient sampling technique by self-made proforma after taking patients’ consent. Anterior and posterior corneal parameters (Kflat, Ksteep, Kavg, R1, R2, Ravg and astigmatism) were measured with GALILEI G4. Pearson correlation test was used for correlation and independent sample t-test / Mann-Whitney U test was used for comparing means of anterior and posterior corneal parameters. Data was entered and analyzed in SPSS-21. Results: Mean of anterior and posterior corneal curvatures was 44.21±1.01 D and -6.22±0.19 D[p
