To evaluate the results of extracapsular cataract extraction (ECCE) and phacoemulsification (PHACO) performed in previously vitrectomized eyes.
In this retrospective study, 56 vitrectomized eyes that had ECCE and 60 vitrectomized eyes that had PHACO were included in the study group while 65 eyes that had PHACO in the control group. The evaluated parameters were the incidence of intra-operative and postoperative complications (IPC) and visual outcomes. Chi-squared, independent samples and paired samples tests were used for comparing the results.
Deep anterior chamber (AC) was significantly more common in the PHACO group of vitrectomized eyes (PGVE) and observed in eyes that had undergone extensive vitreous removal (p < 0.05). Except for this there were no significant differences in the rate of IPC between the ECCE group and the PGVE (p > 0.05). Some of the intra-operative conditions such as posterior synechiae, primary posterior capsular opacification (PCO) and postoperative complications such as retinal detachment (RD), PCO were significantly more common in vitrectomized eyes than the controls (p < 0.05). There was no significant difference in the visual acuity gain between the ECCE group and the PGVE (p > 0.05).
Deep AC is more common in eyes with extensive vitreous removal during PHACO than ECCE. Decreasing the bottle height is advised in this case. Except for this, the results of ECCE and PHACO are similar in previously vitrectomized eyes. Posterior synechiaes, primary and postoperative PCO and RD are more common in vitrectomized eyes than the controls.
评估在既往已行玻璃体切割术的眼中进行囊外白内障摘除术（ECCE）和超声乳化白内障吸除术（PHACO）的效果。
在这项回顾性研究中，研究组纳入了56只接受ECCE的玻璃体切割术后眼和60只接受PHACO的玻璃体切割术后眼，而对照组有65只接受PHACO的眼。评估的参数为术中及术后并发症（IPC）的发生率和视力结果。采用卡方检验、独立样本检验和配对样本检验来比较结果。
在玻璃体切割术后眼的PHACO组（PGVE）中，前房加深明显更常见，且在进行了广泛玻璃体切除的眼中观察到（p<0.05）。除此之外，ECCE组和PGVE组之间的IPC发生率无显著差异（p>0.05）。一些术中情况，如虹膜后粘连、原发性后囊膜混浊（PCO）以及术后并发症，如视网膜脱离（RD）、PCO，在玻璃体切割术后眼中比对照组明显更常见（p<0.05）。ECCE组和PGVE组之间的视力提高无显著差异（p>0.05）。
与ECCE相比，PHACO术中广泛玻璃体切除的眼中前房加深更常见。在这种情况下建议降低灌注瓶高度。除此之外，ECCE和PHACO在既往已行玻璃体切割术的眼中效果相似。玻璃体切割术后眼中虹膜后粘连、原发性及术后PCO和RD比对照组更常见。
