Visual Outcomes and Patient Satisfaction With a New Trifocal, Toric Intraocular Lens

The CNWTTx lens results in excellent visual acuities at distance, intermediate, and near, leading to high rates of spectacle independence and patients are subjectively satisfied with their visual outcomes.

Clinical Performance of an Isofocal Toric Intraocular Lens with Double C-Loop Haptics: A Multicenter Retrospective Study

Purpose To evaluate clinical outcomes in eyes with pre-existing astigmatism undergoing cataract surgery or refractive lens exchange with the implantation of an isofocal optic-design toric intraocular lens (IOL) with double C-loop haptics. Method This multicenter retrospective study comprised 100 eyes (65 patients) implanted with the Isopure Serenity toric IOL (BVI, Inc.) conducted across four sites. Postoperative evaluation at between 2 and 3 months included manifest refraction, monocular uncorrected and distance corrected visual acuity (UDVA and CDVA), monocular uncorrected and distance corrected intermediate visual acuity (UIVA and DCIVA, at 80 and 66 cm), monocular uncorrected and distance corrected near visual acuity (UNVA and DCNVA, at 40 cm), binocular defocus curve and rotational stability. Results Manifest refraction spherical equivalent and refractive astigmatism were −0.24±0.41D and −0.36±0.36D, respectively. About 79% and 97% of eyes were within ±0.50D and ±1.00D, respectively, and 80% and 96% of eyes were ≤0.50D and ≤1.00D of refractive cylinder, respectively. At distance vision, the mean monocular CDVA was −0.02±0.06 logMAR and 92.93% of eyes showed a CDVA of ≥20/20. At intermediate vision, the mean monocular DCIVA values were 0.10±0.07 and 0.17±0.10 logMAR at 80 cm and 66 cm, respectively; and 96.92% and 88.33% of eyes showed a DCIVA of ≥20/32 at 80 cm and 66 cm, respectively. At near vision, the mean monocular DCNVA was 0.31±0.08 logMAR and 75.44% of eyes showed a DCNVA of ≥20/40. The binocular depth of focus range was approximately 1.50D. The mean absolute IOL rotation was 2.73±2.58 degrees with all eyes having a rotation of <10 degrees. Conclusions Eyes with pre-existing astigmatism implanted with the Isopure Serenity toric IOL showed good distance visual acuity and functional intermediate vision, with high refractive accuracy and good rotational stability following cataract and refractive lens exchange surgery.

Visual performance and patient-reported outcomes of a non-apodized diffractive trifocal intraocular lens in Chinese cataract patients: a prospective multicenter real-world study

Bilateral implantation of the PanOptix trifocal IOL provides excellent and early stable visual performance at distance, intermediate, and near in Chinese cataract patients and high refractive predictability and a high rate of spectacle independence are associated with substantial patient satisfaction in real-world clinical practice.

Comparative study on rotational stability of toric intraocular lenses in cataract patients with low astigmatism: vertical versus horizontal implantation.

OBJECTIVE To compare the effects of horizontal versus vertical in-the-bag implantation of toric intraocular lenses (IOLs) on postoperative rotational stability, refractive outcome, and vision-related quality of life in cataract patients with low regular astigmatism, and to identify risk factors for postoperative rotational instability. METHODS This retrospective study included 370 eyes of 370 patients with low regular astigmatism who underwent phacoemulsification with toric IOL implantation. Patients were divided into horizontal implantation (n = 189) and vertical implantation (n = 181) groups according to intraoperative IOL orientation. Follow-up assessments were conducted at 1 week, 1 month, and 3 months postoperatively. The primary outcome was rotational instability at 3 months, defined as a rotation angle ≥ 5°. Secondary outcomes included rotation angle over time, uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), spherical equivalent (SE), residual astigmatism, and National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25) scores. Longitudinal changes were analyzed using a linear mixed-effects model (LMM), and logistic regression was used to identify risk factors. RESULTS Baseline and intraoperative data were comparable between groups. The LMM revealed significant effects of time, group, and their interaction on rotation angle (all P < 0.001). Rotation angles were significantly lower in the vertical implantation group than in the horizontal implantation group at all follow-up time points (all P < 0.001). At 3 months, rotational instability was lower in the vertical group than in the horizontal group (5.5% vs. 16.9%, P < 0.001). The vertical group demonstrated better UCVA, BCVA, SE, and lower residual astigmatism (all P ≤ 0.001), along with higher NEI VFQ-25 scores across multiple domains. Vertical implantation was independently protective (OR = 0.194, 95% CI: 0.077-0.444, P < 0.001), whereas longer axial length, shallower anterior chamber depth, and larger capsular bag diameter were identified as risk factors. Complication rates were similar between groups. CONCLUSION Vertical in-the-bag implantation of toric IOLs provided superior rotational stability, refractive outcomes, visual recovery, and vision-related quality of life compared to horizontal implantation in cataract patients with low regular astigmatism.

Clinical Outcomes after Bilateral Mix-and-Match Implantation of Extended Depth of Focus and Trifocal Intraocular Lenses

Bilateral mix-and-match implantation of EDOF and trifocal IOL implantation showed good visual outcomes for distance, intermediate, and near vision until 12 months, while more than 70% of patients consistently reported that they would recommend the surgery to others.
