Objective To analysis anterior corneal surface shape changes in pediatric myopic overnight or-thokeratology. Methods Retrospective observational case series were observed. Tomey TMS -4 was used to receive corneal topographic data before and after overnight orthokeratology lens wear. Seventy-five pediatric myopic patients (150 eyes, age range: 9~17 years) were included. The myopia was -4.23±1.82 (range:-8.75~-0.75) D, the astigmatism was -0.3±0.47 (range: -2~0) D, and spherical equivalent refraction was -4.34±1.88 (range: -9.13~-0.75) D. Topog-raphy data was collected and analyzed when uncorrected visual acuity (UCVA) was 1.0. Results After normative or-thokeratology lens correction, UCVAs of one hundred and fifty eyes reached 1.0, and no severe complications were ob-served. The topography parameters showed that mean Ks:41.19±1.73D,Kf:39.67±1.67D,AveK:40.43±1.61D, PVA:-0.01±0.09~0.11±0.08 (LogMAR), Es:-0.14±0.47,Em:-0.39±0.34,SRI:0.49±0.33,SAI:0.84±0.60, and were significantly different from no lens wear. No significant change was observed in Cyl (1.48±0.96D) before and after lens wear. The fluctuation range above parameters’ means were ks:0.82±0.83 (0~3.88) D,Kf:0.69±0.75 (0.01~4.54) D,Avek:0.71±0.75 (0.01~3.51) D,Cyl:0.45±0.48 (0.01~2.70) D,Es:0.27±0.31 (0~1.14),Em:0.18±0.24 (0~1.51),Sri:0.19±0.20 (0~1.02),Sai:0.40±0.55 (0~3.65) . Conclusions Improved visual acuity after overnight wear of orthokeratology lens can be attributed to changes in anterior corneal curvature and E value. Corneal regular astigmatism remained unchanged, but corneal PVA reduced and corneal irregularity increased. Improved UCVA can be maintained within a certain fluctuation of topography parameters.
