摘要
目的 探讨硅油填充眼的屈光状态。 方法 用临床视觉光学方法计算硅油填充眼的理论屈光状态 ;对 48例玻璃体切割术后、45例晶状体切割加玻璃体切割术后硅油填充眼视网膜复位患者进行检影 ,研究硅油填充眼屈光度的理论和实际差异。 结果 玻璃体切割术后硅油填充眼屈光度比术前增加了(+6 .2 6± 1.2 0 ) D,晶状体切割加玻璃体切割术后硅油填充眼为 (+11.40± 2 .2 2 ) D,两种术式术后屈光度改变量的理论值则为 +8.92、+12 .30 D。 结论 硅油填充使眼球向远视方向改变 ,实际测量值均低于理论计算值 ,研究两者的关系有助于预测硅油填充眼术后的屈光度。
Purpose To study the refractive state of silicone oil tamponade eyes. Methods To calculate the theoretical refractive state of eyes with silicone oil based on clinical visual optics and to perform retinoscopy on 48 silicone oil filled eyes with pars plana vitrectomy (PPV) and 45 ones with PPV plus lensectomy with retinal reposition, and then study theoretical and experimental differences of diopter in silicone oil filled eyes. Results Postoperative diopter of the former increases (+6.26±1.20) D than preoperative diopter, while that of the latter is (+11.40±2.22) D. Conclusion Hyperopic changes are found in silicone oil tamponade eyes, and the experimental values are lower than the theoretical ones. This may be helpful in predicting the change of diopter of silicone oil tamponade eyes.
