AIM: To observe the changes of the vault height and the correlation analysis of visual quality under different pupil diameters after ICL surgery.METHODS: Retrospective case study. Selected 43 patients(86 eyes)who implanted V4c ICL surgery successfully at Shanghai Aier Eye Hospital and followed up regularly to meet the measurement requirements from January 2018 to January 2019, Routine parameters and iTrace were checked before and 1wk, 1mo, and 3mo after surgery. Visante-OCT was used to measure the vault height under the pupils of 3mm and 5mm. RESULTS: The vault height under the 3mm pupil at 1wk, 1mo and 3mo after surgery were(586.06±24.49, 560.16±21.31, 508.19±21.17)μm, the values under the 5mm pupil were(698.13±20.98, 667.69±20.16, 613.28±19.79)μm(FTime=40.160,PTime0.05). The total high-order aberration(HOA)and RMS of the whole eye after ICL were significantly reduced(F=29.847, 85.019; P0.05). The MTF at 5mm pupils were significantly lower than those at 3mm at spatial frequencies of 5, 10, 15, 20, 25, 30c/d(t=15.138, 9.147, 7.018, 4.693, 3.814 and 3.075, all P |
