■为了评估使用三焦复曲面人工晶状体(IOL)时的屈光和视力结果,飞秒激光辅助白内障手术(FLACS),扫频源光学相干层析成像(SS-OCT)生物测量,数字图像跟踪(DT)和术中像差测量(IA)。
■这个前景,单臂,屈光和视觉结果的观察性研究包括34名受试者的40只眼.使用Argos进行术前生物测量,FLACS和LenSx数字标记,IA和DT与ORA。眼睛植入ClareonPanOptix复曲面IOL。研究结果指标包括绝对预测误差,残余屈光散光,以及远距离单眼未矫正视力和远距离矫正视力(UDVA,CDVA),中间(UIVA,DCIVA;60厘米),和附近(UNVA,DCNVA;40cm)。
■平均绝对预测误差(球面当量)为0.43±0.36D,绝对预测误差≤0.5D的眼睛百分比为72.5%(29/40眼)。平均残余散光为0.36±0.65D,残余散光≤0.5D的眼睛百分比为80%(32/40眼)。单眼UDVA,UIVA,UNVA在75%中为20/25或更高,64%,和87%的眼睛。单眼CDVA,DCIVA,95%的DCNVA为20/25或更高,64%,和87%的眼睛。
■这项研究的结果表明,使用SS-OCT进行三焦环面植入,FLACS,DT,和IA可以提供优异的屈光和视觉结果。
当眼睛内部的自然晶状体变得不透明(发展为白内障)时,它可以通过手术替换为透明人工晶状体(IOL)。白内障外科医生可以使用许多不同的技术来最大化植入IOL的术后视觉结果。这些包括,现代生物测定,飞秒激光辅助白内障手术(FLACS),三焦IOL,复曲面IOL,图像引导数字跟踪(DT),术中像差测定(IA)。个别地,据报道,这些技术具有良好的屈光效果。然而,使用所有这些组合的结果数据很少。这项研究的目的是确定屈光和视力结果时,使用现代生物测定,复曲面IOL,FLACS,DT,IA,和三焦点IOL。这项研究的结果表明,三焦复曲面植入与现代生物统计学,FLACS,DT,和IA可以提供优异的屈光和视觉结果。
UNASSIGNED: To evaluate the refractive and visual acuity outcomes when using trifocal toric intraocular lenses (IOLs), femtosecond laser assisted cataract surgery (
FLACS), swept-source optical coherence tomography (SS-OCT) biometry, digital image tracking (DT) and intraoperative aberrometry (IA).
UNASSIGNED: This prospective, single-arm, observational study of refractive and visual outcomes included 40 eyes of 34 subjects. Preoperative biometry was performed with the Argos,
FLACS and digital marking with LenSx, and IA and DT with ORA. Eyes were implanted with the Clareon PanOptix toric IOL. Study outcome measures included absolute prediction error, residual refractive astigmatism, and monocular uncorrected and distance corrected visual acuity at distance (UDVA, CDVA), intermediate (UIVA, DCIVA; 60cm), and near (UNVA, DCNVA; 40cm).
UNASSIGNED: Mean absolute prediction error (spherical equivalent) was 0.43 ± 0.36 D, and the percentage of eyes with absolute prediction error ≤ 0.5 D was 72.5% (29/40 eyes). Mean residual astigmatism was 0.36 ± 0.65 D, and the percentage of eyes with residual astigmatism ≤ 0.5 D was 80% (32/40 eyes). Monocular UDVA, UIVA, and UNVA was 20/25 or better in 75%, 64%, and 87% of eyes respectively. Monocular CDVA, DCIVA, and DCNVA was 20/25 or better in 95%, 64%, and 87% of eyes respectively.
UNASSIGNED: The results of this study suggest that trifocal toric implantation with SS-OCT,
FLACS, DT, and IA can provide excellent refractive and visual outcomes.
When the natural lens inside the eye becomes opaque (develops a cataract), it can be surgically replaced with a clear artificial intraocular lens (IOL). There are many different technologies available to the cataract surgeon in order to maximize postoperative visual outcomes with implanted IOLs. These include, modern biometers, femtosecond laser-assisted cataract surgery (
FLACS), trifocal IOLs, toric IOLs, image-guided digital tracking (DT), and intraoperative aberrometry (IA). Individually, good refractive outcomes have been reported with these technologies. However, there is minimal data on outcomes using a combination of all of them. The purpose of this study was to determine the refractive and visual acuity outcomes when using modern biometers, toric IOLs, FLACS, DT, IA, and trifocal IOLs. The results of this study suggest that trifocal toric implantation with modern biometry,
FLACS, DT, and IA can provide excellent refractive and visual outcomes.
