To evaluate and compare dynamic vault range (DVR) and asymmetry of the vault during a 3-month follow-up after the implantation of 2 posterior chamber phakic intraocular lenses (pIOLs).
Aver Clinic, Madrid, Spain.
Prospective comparative study.
119 eyes (65 patients) that underwent refractive surgical correction with implantation of 1 of 2 distinct pIOLs were enrolled: Eyecryl Phakic from Biotech Vision Care (Eyecryl group, 72 eyes) and Evo Visian Implantable Contact Lens from Staar Surgical (ICL group, 47 eyes). Besides evaluation of visual acuity, refraction, and ocular integrity, the pIOL vault centrally and at 2 mm nasally and temporally as well as the DVR from photopic (50 lux) to mesopic (10 lux) illumination conditions were measured.
No significant differences were found between the pIOL groups in visual and refractive outcomes ( P ≥ .454). No significant differences between the groups were found in central (523.72 ± 168.4 vs 494.16 ± 156.7 μm, P = .248) and temporal (499.43 ± 155.8 vs 431.28 ± 150.5 μm, P = .067) vaults. However, nasal vault was significantly lower in the ICL group (465.6 ± 149.1 vs 375.4 ± 144.0 μm, P = .045). A trend of a larger DVR was observed in the ICL group, although differences between groups did not reach statistical significance (54.00 ± 36.39 vs 86.5 ± 57.9 μm, P = .070). The pIOL diameter only correlated significantly with vault measurements in the ICL group ( r ≥ 0.650, P < .001).
The Eyecryl pIOL showed more symmetric vaults and a trend of fewer light-induced changes in the central vault compared with the ICL pIOL. The clinical relevance of this finding should be investigated further.
评估并比较2种后房型有晶状体眼人工晶状体（pIOL）植入术后3个月随访期间的动态房拱顶范围（DVR）及房拱顶的不对称性。

前瞻性比较研究。
纳入119只眼（65例患者），这些患者接受了屈光手术矫正并植入了2种不同pIOL中的1种：来自生物技术视力保健公司的Eyecryl Phakic（Eyecryl组，72只眼）和来自STAAR外科公司的Evo Visian可植入接触镜（ICL组，47只眼）。除了评估视力、屈光和眼部完整性外，还测量了pIOL在中央、鼻侧和颞侧2 mm处的房拱顶以及从明视（50勒克斯）到中视（10勒克斯）照明条件下的DVR。
pIOL组在视力和屈光结果方面未发现显著差异（P≥0.454）。两组在中央（523.72±168.4 vs 494.16±156.7μm，P = 0.
