To explore short-term changes in corneal astigmatism after combined silicone oil removal and cataract (SORC) surgery.
We enrolled 89 patients (43 men and 46 women). Zeiss IOLMaster was used to measure corneal astigmatism status and axial length on the day before and after the SORC surgery. Best-corrected visual acuity (BCVA) and intraocular pressure (IOP) were recorded. The results were compared to the outcomes at 3 days, 1 week, and 1 month postoperatively.
Compared to baseline, K1 decreased significantly at 3 days postoperatively ( = 0.016), 1 week ( = 0.009), and 1 month ( = 0.035), while K2 increased significantly at 3 days postoperatively (P = 0.002), 1 week ( < 0.001), and 1 month ( = 0.001), as well as corneal astigmatism (all < 0.001). Compared to that at the baseline, BCVA significantly improved at 3 days, 1 week, and 1 month postoperatively (all < 0.001). Meanwhile, IOP decreased significantly at 3 days postoperatively ( < 0.001), 1 week ( = 0.005), and 1 month ( = 0.007). Similarly, axial length decreased at all follow-up time points (all < 0.001).
Corneal astigmatism increased in the short term after the SORC operation but gradually decreased at 1 month postoperatively. BCVA improved steadily, and SORC was widely used in the clinic.
探讨硅油取出联合白内障（SORC）手术后角膜散光的短期变化。
我们纳入了89例患者（43例男性和46例女性）。使用蔡司IOLMaster在SORC手术前后测量角膜散光状态和眼轴长度。记录最佳矫正视力（BCVA）和眼压（IOP）。将结果与术后3天、1周和1个月时的结果进行比较。
与基线相比，术后3天（P = 0.016）、1周（P = 0.009）和1个月（P = 0.035）时K1显著降低，而术后3天（P = 0.002）、1周（P < 0.001）和1个月（P = 0.001）时K2以及角膜散光均显著增加（均P < 0.001）。与基线时相比，术后3天、1周和1个月时BCVA均显著改善（均P < 0.001）。同时，术后3天（P < 0.001）、1周（P = 0.005）和1个月（P = 0.007）时IOP显著降低。同样，在所有随访时间点眼轴长度均降低（均P < 0.001）。
SORC手术后短期内角膜散光增加，但术后1个月逐渐降低。BCVA稳步改善，SORC在临床上得到广泛应用。
