研究目的
To compare the various Pentacam-measured K-readings with the clinical history method (CHM) in eyes that have undergone myopic laser in situ keratomileusis (LASIK).
研究成果
The EKR4.0mm demonstrated the closest agreement with the KCHM when compared with the EKR4.5mm, TNP4mm, and TCRP4mm obtained from the same scan, suggesting its potential utility in IOL power calculations post-myopic LASIK.
研究不足
The study did not perform back-calculation of corneal power from the actual IOL outcomes due to the clear lens status of LASIK cases. The reliance on CHM as the benchmark for comparison is increasingly challenged with newer generations of IOL formulae.
1：Experimental Design and Method Selection:
Prospective study comparing Pentacam-measured K-readings (TNP4mm, TCRP4mm, EKR
2：0mm, EKR5mm) with K derived from CHM in post-myopic LASIK eyes. Sample Selection and Data Sources:
71 eyes from 36 consecutive patients who underwent myopic LASIK, with Pentacam examination performed 1 month post-surgery.
3：List of Experimental Equipment and Materials:
Pentacam AXL (software version 1.20r101; Oculus), iFS femtosecond laser platform (AMO), excimer laser stroma ablation (Allegretto, wavelight).
4：20r101; Oculus), iFS femtosecond laser platform (AMO), excimer laser stroma ablation (Allegretto, wavelight). Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: Data collection included refraction, keratometry readings, and Pentacam AXL before and 1 month after LASIK.
5：Data Analysis Methods:
Comparison of K-readings with KCHM using t-test, Bland-Altman plots for agreement analysis, and Pearson correlation analysis.
