To review refractive, visual acuity, defocus curve and contrast sensitivity results after bilateral implantation of a trifocal intraocular lens (IOL) in a large population.
One site in Santiago, Chile.
Single arm, non-randomized retrospective chart review.
This was a single-arm retrospective chart review of clinical outcomes after bilateral implantation of a trifocal IOL (Panoptix), both toric and non-toric versions. Binocular visual acuity at 4 m, 60 cm and 40 cm was tested. Other tests included refraction, mesopic and photopic contrast sensitivity, and defocus curve measurement.
The review included 500 eyes of 250 patients implanted with the trifocal IOL and 200 eyes of 100 patients implanted with the trifocal toric IOL, with no clinically significant differences between groups. Ninety-six percent of all eyes were within 0.50D of the intended spherical equivalent correction. In the toric group, 94% of eyes (187/200) had a residual refractive cylinder ≤0.50D, compared to 81% of eyes (406/500) in the non-toric group. Four out of five patients (80.6%, 282/350) had a binocular uncorrected VA of 0.1 logMAR (20/25) at all test distances. Mean defocus was 0.1 logMAR or better from vergences from 0.00 to -3.00 D (corresponding to vision from distance to about 33 cm). With a cutoff of 0.2 logMAR, 96% of patients had a range of vision 2.5 D or greater. Contrast sensitivity was similar between the toric and non-toric lenses, and similar to age-matched normal results.
The non-toric and toric trifocal IOLs provided good distance, intermediate and near vision to patients, with a wide range of vision and good contrast sensitivity.
回顾在大量人群中双侧植入三焦点人工晶状体（IOL）后的屈光、视力、散焦曲线和对比敏感度结果。
智利圣地亚哥的一个地点。
单臂、非随机回顾性病历审查。
这是一项对双侧植入三焦点IOL（Panoptix）（包括散光和非散光型号）后的临床结果进行的单臂回顾性病历审查。测试了4米、60厘米和40厘米处的双眼视力。其他测试包括验光、中视和明视对比敏感度以及散焦曲线测量。
该审查纳入了250例植入三焦点IOL的患者的500只眼以及100例植入三焦点散光IOL的患者的200只眼，两组之间无临床显著差异。所有眼中96%的眼在预期球镜等效矫正的0.50D范围内。在散光组中，94%的眼（187/200）残余屈光柱镜≤0.50D，相比之下非散光组为81%的眼（406/500）。五分之四的患者（80.6%，282/350）在所有测试距离下双眼未矫正视力均为0.1 logMAR（20/25）。从0.00到 -3.00 D的聚散度（对应从远到约33厘米的视力）下，平均散焦为0.1 logMAR或更好。以0.2 logMAR为截止值，96%的患者视力范围为2.5 D或更大。散光和非散光晶状体之间的对比敏感度相似，且与年龄匹配的正常结果相似。
非散光和散光三焦点IOL为患者提供了良好的远、中、近视力，视力范围广且对比敏感度良好。
