“…The anteriorly offset haptics of the Tecnis lens enable a three-point fixation with the posterior capsule. According to Miyata et al [ 22 ], the one-piece Tecnis IOL showed a better stability than the three-piece IOL. They measured a mean postoperative ACD of 4.14 mm in eyes with mean AL of 23.37 mm twelve months after surgery with Scheimpflug camera, not including the corneal thickness.…”

Background The purpose of this prospective, randomised study was to interocularly compare the visual performance after implantation of two different toric IOLs with different haptic design. Methods 59 subjects with corneal astigmatism greater than 1.25 diopter (D) were implanted with an AT TORBI 709M IOL (Carl Zeiss Meditec AG) in one eye and with a Tecnis toric aspheric IOL (Abbot Medical Optics) in the other eye. Observation procedure was performed 12 months postoperatively. Main outcome measures included uncorrected distance visual acuity (UDVA), manifest refraction, IOL rotation, and IOL position. Results Mean UCDVA was 0.04 ± 0.14 logMAR for AT TORBI eyes and 0.06 ± 0.15 logMAR for Tecnis eyes (p = 0.3). The postoperative spherical equivalent values were significantly lower in the AT TORBI group. Mean toric IOL axis rotation was 3.0 ± 2.26 degrees for AT TORBI eyes and 3.27 ± 2.37 for Tecnis eyes (p = 0.5). The mean vertical IOL tilt and vertical decentration values measured with the Visante OCT were significantly larger in the AT TORBI group (p < 0.05). Conclusions Both the Tecnis and the AT TORBI toric IOLs successfully reduced ocular astigmatism. Emmetropia could be better achieved with the AT TORBI IOL, whereas the Tecnis showed better positional stability. This trial is registered with ICMJE NCT03371576.

“…The SE became more hyperopic significantly in the early Nd:YAG group compared with that in the late Nd:YAG group in the current study. In previous studies, the SE showed similar value after Nd:YAG laser capsulotomy whether in monofocal or multifocal IOL [21,24], and no related factors for the hyperopic or myopic change of SE were found except for the IOL design [19,20,25]. However, those studies did not consider the effect of Nd:YAG laser capsulotomy at different time periods, which may be a critical factor for the refraction since IOL stability is not consistent after the cataract surgery [22].…”

We aimed to determine the timing of neodymium:yttrium–aluminum–garnet (Nd:YAG) laser capsulotomy on corrected-distance visual acuity (CDVA), intraocular pressure (IOP), and spherical equivalent (SE) in patients with posterior capsular opacification (PCO). There were 59 patients with unilateral PCO and a history of Nd:YAG laser capsulotomy enrolled and further divided into the early Nd:YAG group (timing < 12 months, n = 25) and late Nd:YAG group (timing > 12 months, n = 34) depending on the elapsed months from phacoemulsification to Nd:YAG laser capsulotomy. The primary outcomes were CDVA, IOP, and SE before (immediately before Nd:YAG laser capsulotomy) and after (weeks one and four after the laser treatment). The independent t test was applied to analyze the difference in CDVA, IOP, and SE between the two groups, while the generalized estimating equation with Bonferroni adjustment was conducted to evaluate the effect of all the parameters on the change in SE with adjusted odds ratio (aOR) and 95% confidence interval (CI). The CDVA showed significant improvement in both the early Nd:YAG group (p = 0.005) and the late Nd:YAG group (p = 0.001), and hyperopic change occurred in both the early Nd:YAG group (p = 0.003) and the late Nd:YAG group (p = 0.017). The early Nd:YAG group revealed more significant hyperopic change compared with the late Nd:YAG group four weeks after Nd:YAG treatment (p < 0.001), which was still significant after multivariable analysis (aOR: 0.899, 95% CI: 0.868–0.930, p = 0.011). In addition, a deeper ACD (aOR: 0.764, 95% CI: 0.671–0.869, p = 0.019) was significantly correlated with hyperopic change. In conclusion, Nd:YAG laser capsulotomy performed within one year after cataract surgery may lead to significant hyperopic change, in which the ACD alteration affects the hyperopic shift significantly.

“…2015; Miyata et al. 2015). However, our results in Group B (three‐piece IOL in PXF eyes) did not show any significantly shallower depth value for ACD, although they indicated a slight myopia in comparison to Group A (one‐piece IOL in PXF eyes) and Group C (one‐piece IOL in non‐PXF eyes).…”

Purpose To evaluate the refractive precision of three‐piece versus one‐piece intraocular lenses (IOLs) in eyes with pseudoexfoliation (PXF) and changes in anterior chamber depth (ACD) following cataract surgery. Methods This prospective, nonrandomized, interventional, comparative case series included PXF eyes, which were implanted with one‐piece acrylic IOL or three‐piece acrylic IOLs (Group A; n = 31, Group B; n = 30). Non‐PXF control eyes were implanted with one‐piece acrylic IOL (Group C; n = 30). Postoperative refractive error (RE) and absolute RE, as well as pre‐ to postoperative ACD changes, were statistically analysed. A p value < 0.05 was considered statistically significant. Results Changes in ACD (mean ± standard deviation) in Groups A, B and C were 0.9 ± 0.4, 1.0 ± 0.3 and 0.7 ± 0.4 mm, respectively. Significant differences were found between Groups A and C (p = 0.043) and between Groups B and C (p = 0.008). In Groups A, B and C, the median and interquartile (Q1 to Q3) values were 0.3 (−0.8 to 1.0), −0.5 (−0.8 to −0.3) and 0.1 (−0.4 to 0.3) for RE and 1.0 (0.4 to 1.3), 0.5 (0.3 to 0.8) and 0.3 (0.3 to 0.5) for absolute RE, respectively. The RE differences between Group A and B (p = 0.009) and Group B and C (p < 0.001) were statistically significant. For absolute RE, the differences were significant for all comparisons (p < 0.05). Conclusion Refractive precision in PXF eyes may be better with three‐piece than with one‐piece IOL implantation, but worse than with one‐piece IOL implantation in non‐PXF eyes. Significant changes in ACD in PXF eyes may be related to RE.

Prospective Comparison of One-Piece and Three-Piece Tecnis Aspheric Intraocular Lenses: 1-year Stability and its Effect on Visual Function

Abstract: The stability of the one-piece IOL was greater than that of the three-piece IOL. The postoperative ACD and refractive error demonstrated that an anteriorly offset haptic in the one-piece IOL allowed incremental fixation to the posterior capsule.
