“…14 The same authors in another study considering only low IOL cylinder power (1.0 D) found 81% and 96% of eyes both had a UDVA and CDVA of 20/20 (100% of eyes were 20/25), with the mean monocular Snellen decimal UDVA and CDVA values of 0.97 ± 0.05 and 0.99 ± 0.02 (about 20/20), respectively. 15 Our findings, and those published previously by other authors for short-term and medium-term followups, evidence that this trifocal toric IOL improves intermediate vision without negatively affecting far distance or near vision.…”

“…Several clinical studies have been published showing the refractive and visual outcomes of eyes implanted with the FineVision POD FT IOL for different amounts of corneal astigmatism. [7][8][9][10][11][12][13][14][15][16] Supplementary Table 3 (available at http://links.lww.com/JRS/A866) presents the main characteristics of these studies in which the usual follow-up ranged between 1 and 4 months with 22 to 145 in the sample; in our study, we considered even more eyes (187) with a longer follow-up period (2 years), and also, specifically, these were Asian eyes. To date, therefore, our study assesses the largest sample of Asian eyes implanted with this trifocal toric IOL that underwent cataract surgery and with the longest follow-up.…”

“…7 Nistad et al found a mean MRSE of À0.09 ± 0.39 D; Poyales et al found a mean MRSE of À0.17 ± 0.10 D; Poyales and Garzón reported a mean MRSE of À0.08 ± 0.21 D and a cylinder of À0.14 ± 0.31 D; and Ribeiro and Ferreira showed a mean MRSE of À0.20 ± 0.39 D and a cylinder of À0.27 ± 0.39 D. 8,10,11,13 In 2 studies, Orts-Vila et al found a mean MRSE of 0.07 ± 0.28 D and a cylinder of À0.23 ± 0.32 D and À0.02 ± 0.23 D and À0.16 ± 0.22 D, respectively. 14,15 All these studies were performed over a short follow-up period (3 to 4 months postoperatively). Note that our results at 4 to 6 months were similar: À0.07 ± 0.31 and À0.45 ± 0.37 D for MRSE and cylinder, respectively.…”

“…A number of clinical studies analyzing this lens have been published, showing good visual acuity at different distances and good refractive outcomes for varying amounts of corneal astigmatism. [7][8][9][10][11][12][13][14][15][16] However, to date, there has been no long-term analysis of this lens specifically in Asian eyes. The main purpose of this prospective noncomparative study was, therefore, to evaluate the refractive and visual outcomes at different times postcataract surgery in a large series of Asian eyes with corneal astigmatism implanted with the FineVision PODFT IOL and followed-up for 2 years.…”

Purpose: To determine the visual and refractive outcomes of trifocal toric intraocular lens (IOL) implantation in Asian eyes with cataract and astigmatism. Setting: Asian Eye Institute, Makati City, Philippines. Design: Prospective study. Methods: 187 eyes were implanted with the FineVision POD FT IOL and followed for 2 years. The measurements included subjective refraction, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), distance-corrected intermediate visual acuity (DCIVA), uncorrected near visual acuity (UNVA), distance-corrected near visual acuity (DCNVA), defocus curve, photopic and mesopic contrast sensitivity, and rotational stability. Results: The mean spherical equivalent and cylinder values were, respectively, −0.07 ± 0.34 diopters (D) and −0.48 ± 0.31 D at the 2-year follow-up. At this same follow-up, 69.4% of patients had monocular CDVA and 79.3% had binocular UDVA ≤0.0 logMAR. For intermediate vision, monocular DCIVA reached 74.1%, while binocular UIVA was 86.2% ≤ 0.1 logMAR. Near vision showed 63% for monocular DCNVA and 70.7% for binocular UNVA ≤0.1 logMAR. The mean values at this follow-up were 0.02 ± 0.08, 0.08 ± 0.10, and 0.10 ± 0.12 logMAR for CDVA, DCIVA, and DCNVA, respectively. At the visual acuity threshold of ≤0.20 logMAR, the binocular defocus curve extended up to −3.75 D. Stable contrast sensitivity values were obtained at the different follow-ups. The mean IOL rotation was ≤2 degrees. Conclusions: The FineVision POD FT IOL yielded good visual outcomes at far, near, and intermediate distances with accurate refractive outcomes and good rotational stability in Asian eyes.

“…The postoperative refractive cylinder was 0.18 ± 0.17 D (toric) and 0.91 ± 0.25 D (spherical) ( P < 0.001), but no comparison is available between groups for the preoperative corneal cylinder. Orts-Vila et al reported about 26 eyes with preoperative corneal astigmatism of 0.62 ± 0.38 D (0.12 to 1.41), implanted with 1.0 D toric trifocal IOL [ 28 ]. They obtained a mean postoperative refractive cylinder of 0.16 ± 0.22 D (0.00 to 0.50); this study also had no comparison group.…”

Purpose To investigate the advantages/disadvantages of a 1.0 D toric IOL vs spherical IOL after regular phacoemulsification in eyes with preoperative astigmatism ≤ 1 D. Methods Retrospective comparative series involving pseudophakic eyes with preoperative topographic astigmatism ≤ 1.0 D implanted either with monofocal 1.0 D Toric IOL (T-group), or with spherical IOL (S-group). The postoperative refractive astigmatism (PRA, i.e. surgically induced + corneal) was the main outcome; also considered in the analyses were the uncorrected and best-corrected distance visual acuity (VA). The data were referred to the last postoperative follow-up visit, 2 to 4 months after surgery. Results A total of 60 eyes were included: 30 in the T-group and 30 in the S-group, matched for patient’s age, laterality, and axial length. Before surgery, the mean corneal astigmatism was 0.62 ± 0.39 D in the T-group and 0.54 ± 0.33 D in the S-group (p = 0.4). In the S-group, PRA was 0.73 ± 0.37 D, higher than the corresponding preoperative corneal astigmatism (p = 0.040). In the T-group, PRA was 0.58 ± 0.31 D; the variation was not statistically significant. Uncorrected VA was significantly better in the T-group vs the S-group (p = 0.007), and the best-corrected VA was comparable in the two groups. Conclusion The present study indicated that in eyes with very low preoperative astigmatism, 1.0 D toric IOLs were able to limit the increase of the PRA instead of those observed with the spherical IOLs. This could support the better uncorrected VA recorded in the T-group.

Intraoperative aberrometry: an update on applications and outcomes

Purpose of reviewThere is now a large body of experience with intraoperative aberrometry. This review aims to synthesize available data regarding intraoperative aberrometry applications and outcomes. Recent findingsThe Optiwave Refractive Analysis (ORA) System utilizes Talbot-moir e interferometry and is the only commercially available intraoperative aberrometry device. There are few studies that include all-comers undergoing intraoperative aberrometry-assisted cataract surgery, as most studies examine routine patients only or atypical eyes only. In non-post-refractive cases, studies have consistently shown a small but statistically significant benefit in spherical equivalent refractive outcome for intraoperative aberrometry versus preoperative calculations. In studies examining axial length extremes, most studies have shown intraoperative aberrometry to perform similarly to preoperative calculations. Amongst post-refractive cases, post-myopic ablation cases appear to benefit the most from intraoperative aberrometry. For toric intraocular lenses (IOLs), intraoperative aberrometry may be used for refining IOL power (toricity and spherical equivalent) and alignment, and most studies show intraoperative aberrometry to achieve low postoperative residual astigmatism.
