Changes of the effective optical zone after small-incision lenticule extraction and a correlation analysis
The objective of the study is to observe the changes in the effective optical zone (EOZ) after small incision lenticule extraction (SMILE) and explore possible correlations with some influencing factors. In total, 133 eyes after SMILE were divided into the mild to moderate myopia group (− 1.75 D to ...

| description | The objective of the study is to observe the changes in the effective optical zone (EOZ) after small incision lenticule extraction (SMILE) and explore possible correlations with some influencing factors. In total, 133 eyes after SMILE were divided into the mild to moderate myopia group (− 1.75 D to − 5.75 D, 70 eyes) and the high myopia group (− 6.00 D to − 9.50 D, 63 eyes). The postoperative EOZ was calculated by utilizing the corneal tangential curvature map. Changes in EOZ (△-OZ) were monitored and compared between the two groups. Pearson correlation analysis was conducted to determine the correlation between △-OZ and corneal high-order wavefront aberrations. Multicollinearity analysis and ridge regression analysis were performed to assess the correlation between △-OZ and some corneal parameters. After SMILE, the horizontal EOZ (H-EOZ), vertical EOZ (V-EOZ), and average EOZ (A-EOZ) were significantly smaller than the programmed optical zone (POZ) in both groups (

Consideration of the refractive diopter and corneal topography is advised for the design of POZ, the latter of which has greater reference significance.</abstract><cop>London</cop><pub>Springer London</pub><pmid>36547739</pmid><doi>10.1007/s10103-022-03666-1</doi><tpages>1</tpages><orcidid>https://orcid.org/0000-0001-7813-949X</orcidid></addata></record> |
