“…A new diffractive trifocal toric IOL is now available (PhysIOL ® , POD AY 26P F-T; FineVision Toric); it utilizes the same multifocal principles as the FineVision trifocal IOL and the same toric principles as the Ankoris IOL (PhysIOL ® ; Ankoris, Liège, Belgium). 14 The Ankoris IOL is a hydrophilic aspheric toric IOL utilizing double-C loop quadripode haptics for stabilization. 15 The purpose of the current study is to compare the refractive and VA outcomes, including LCVA, as well as the patient’s visual function 3 months after implantation of this new diffractive trifocal toric IOL with the ReSTOR SND1T apodized diffractive bifocal toric IOL.…”

PurposeThe aim of this study was to compare a new diffractive trifocal toric lens with an apodized diffractive bifocal toric lens in terms of refractive and visual acuity (VA) outcomes, including low-contrast VA (LCVA), as well as the patient’s visual function 3 months after implantation.Patients and methodsThis is a randomized prospective study involving bilateral implantation of a trifocal toric or a bifocal toric lens. At 3 months postoperatively, the subject’s vision was tested both uncorrected and with his/her best distance correction at: distance (4 m), intermediate (63 cm), and near (40 cm). Binocular defocus curves were measured with no correction and with the subject’s best distance correction in place. Quality of vision was measured using the National Eye Institute Visual Function Questionnaire.ResultsA total of 22 patients were enrolled (eleven in each group). There was no statistically significant difference in the absolute change in measured rotation between 1 month and 3 months postoperatively between the two intraocular lens (IOL) groups (P=0.98). At 3 months, the postoperative refraction and distance VA by eye were similar between groups. There was no statistically significant difference in the measured LCVA between groups (P=0.39). The defocus curve showed that at 67 cm, the trifocal toric lens had statistically significantly better VA when compared to the bifocal toric lens. There were no statistically significant differences by group for any of the National Eye Institute Visual Function Questionnaire scores (P>0.26 in all cases).ConclusionThe trifocal toric IOL improved the intermediate vision without negatively impacting visual function and distance, near, or low-contrast VA when compared to a bifocal toric IOL. The toric component of the trifocal lens effectively reduced astigmatism and provided good rotational stability.

“…Mencucci et al reported that the mean IOL rotation was 3.00 ± 1.69° postoperatively [ 21 ]. Chassain C provided a similar result that the mean IOL rotation was 2.16 ± 1.95° [ 22 ]. According to Visser N et al, a commonly used 3-step ink-marker procedure before implanting toric IOLs produced a mean off-axis error of approximately 5° [ 23 ].…”

BackgroundTo construct a real-time computerized location system (RCLS) to analyze and display the axis of corneal astigmatism and to compare its accuracy with the Scheimpflug method.MethodsFifty-seven eyes of 39 volunteers with corneal astigmatism more than 1.00 diopter (D) were recruited. The RCLS was composed of a circular light-emitting diode (LED) light source, surgical microscope, surgical video system, computer and self-programming image analysis software. Scheimpflug imaging measurements (Pentacam HR, Oculus, Wetzlar, Germany) were performed on all subjects to determine the axis and power of corneal astigmatism. Thereafter, the axis of corneal astigmatism was analyzed in real-time and displayed by the RCLS on supine position, and videos were recorded. The MB-Ruler 4.0 software was used to measure the astigmatic axis. The accuracy of the RCLS was compared with the Scheimpflug method.ResultsThe RCLS was able to display the axis of corneal astigmatism in real-time. The axial deviation of corneal astigmatism between the two methods was 0.63 ± 3.78° when astigmatism was 1.00 to 2.00 D and decreased to 0.06 ± 1.38° when astigmatism was greater than 2.00 D. A linear correlation of astigmatic axis was noted between the two methods: AxisRCLS = 1.01 × AxisScheimpflug − 1.02 (R2 = 0.998, P < 0.001). The Bland-Altman analysis revealed that the RCLS agreed sufficiently well with the Scheimpflug method.ConclusionsThe RCLS can accurately analyze and display the axis for corneal astigmatism greater than 1.00 D in real-time. The RCLS simplifies marking procedures and may have potential clinical application to improve the postoperative visual outcomes in surgical correction of corneal astigmatism.

“…Another IOL using the same C-loop design, the Akoris toric IOL (BVI, Waltham, USA), also presented a similar absolute mean rotation: 2.16±1.95 degrees. 6 The difference between these two lenses is the IOL material: hydrophobic in the case of the PODEYE toric lens versus hydrophilic for the Ankoris toric lens. The double C-loop design has shown good stability when implanted into the capsular bag.…”

Purpose To show the visual and refractive outcomes in cataract patients with corneal astigmatism when bilaterally implanted with a biconvex aspheric toric monofocal intraocular lens (IOL) with a double C-loop haptic-design. Methods Forty-seven cataract patients (94 eyes) with corneal astigmatism (≥0.75D) were implanted with the monofocal PODEYE toric IOL and assessed for 4–6 months post-surgery. Measurements included monocular and binocular uncorrected-distance visual acuity (UDVA) and corrected-distance visual acuity (CDVA), under both photopic and mesopic lighting conditions. Refraction, photopic and mesopic contrast sensitivity (with and without glare), and rotational stability were also recorded at the last postoperative visit. Results At 4–6 months, 78.2% and 98.9% of eyes were within ±0.50D and ±1.00D of the target refraction, respectively. The mean spherical equivalent and refractive cylinder values were 0.09±0.35D and −0.36±0.35D, respectively. 76.5% and 98.8% of eyes presented a postoperative refractive cylinder of ≤0.50D and ≤1.00D, respectively. 91.5% and 100% of patients had a binocular UDVA and CDVA of ≥20/25, respectively. The mean binocular UDVA and CDVA were 0.02±0.08 and −0.02±0.07 logMAR, respectively. Under mesopic conditions, 78.7% and 83.0% of patients presented a binocular UDVA and CDVA ≥20/32, respectively. The mean binocular UDVA and CDVA were 0.15±0.11 and 0.12±0.11 logMAR, respectively. The patients showed good contrast sensitivity under photopic and mesopic conditions. The mean absolute IOL rotation was 1.22±2.21 degrees with 97.87% of eyes having a rotation of <10 degrees. Conclusion This study shows good visual and refractive outcomes for the PODEYE toric IOL when implanted bilaterally in cataract patients with corneal astigmatism.
