Comparison of clinical outcomes of trifocal intraocular lens (AT LISA, Eyecryl SERT trifocal) versus extended depth of focus intraocular lens (Eyhance, Eyecryl SERT EDOF)

Purpose: To compare four different types of intra ocular lenses (IOLs), namely, AT LISA, Eyecryl SERT trifocal, Eyhance, Eyecryl SERT extended depth of focus (EDOF) with respect to their clinical outcomes. Methods: This is a retrospective comparative study in which patients who underwent surgery and one of the four types of IOL were implanted. Postoperative evaluation was recorded at one month, postoperatively. The monocular uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA) (6 m), uncorrected intermediate visual acuity (UIVA) (60 cm), distance-corrected intermediate visual acuity (CIVA), uncorrected near visual acuity (UNVA) (40 cm), and corrected near visual acuity (CNVA) were assessed postoperatively on post operative day 30, for all four IOL groups. Defocus curve and contrast sensitivity were also compared. Results: With regards to UDVA and CDVA, P value was not statistically significant. (P = 0.534 and 0.421, respectively). EDOF group of IOLs had statistically significant better UIVA and CIVA than trifocal IOL group. (P < 0.001, 0.012, <0.001) and EDOF group had statistically significant worse P value pertaining to UNVA and CNVA (P < 0.001, 0.070, <0.001, 0.190). Pertaining to contrast sensitivity, EDOF group had better contrast sensitivity than Trifocal IOL group (P < 0.001). Conclusion: All four IOLs compared in this study had good comparable distant visual acuity. Near visual acuity was better with AT LISA and Eyecryl SERT trifocal IOL while intermediate vision was better with Eyhance and Eyecryl SERT EDOF IOL. Contrast sensitivity was better in EDOF IOLs than in both trifocal IOLs

Clinical Outcomes of Diffractive Aspheric Trifocal Intraocular Lens Implantation

PURPOSE: To evaluate the clinical outcomes of patients with diffractive aspheric trifocal intraocular lens FineVision Pod F IOL (PhysIOL, Liège, Belgium) implantation. METHODS: Thirty eight eyes received phacoemulsification and implantation of FineVision Pod F IOL. Uncorrected distant visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), refractive values, and defocus curve were evaluated at postoperative 1 month and 3 months. Optical quality was evaluated with the contrast sensitivity test, OQAS® (Optical Quality Analysis System, Visiometrics, Cerdanyola del Vallès, Spain) and questionnaire. RESULTS: At the 3-month postoperative follow-up, the mean spherical equivalent was 0.01 ± 0.31 D and the mean UDVA, UIVA and UNVA were 0.04 ± 0.07, 0.19 ± 0.12, and 0.04 ± 0.07, respectively. Mean contrast sensitivities at 0.75, 1.5, 3, 6, 12, and 18 cycles per degrees were 2.00 ± 1.54, 2.16 ± 1.60, 2.25 ± 1.76, 2.16 ± 1.83, 1.52 ± 1.47 and 1.03 ± 0.95 respectively and mean objective scatter index by OQAS® (Optical Quality Analysis System, Visiometrics) was 1.54 ± 0.74. In satisfaction analysis, general satisfaction with surgery was 89% and spectacle independence were 89% at far, 78% at intermediate and 83% at near distance. Postoperative dissatisfaction factors were dryness (36%), glare at night (32%), halo (18%). CONCLUSIONS: The FineVision Pod F IOL showed excellent distant and near visual acuities with an effective intermediate visual acuity. The eyes with FineVision Pod F IOL expected to achieve the favorable visual outcome and patient satisfaction.

Clinical Outcomes of Diffractive Aspheric Trifocal Intraocular Lens Implantation

PURPOSE: To evaluate the clinical outcomes of patients with diffractive aspheric trifocal intraocular lens (AT.LISA tri839 MP(R) IOL, Carl Zeiss Meditec, Jena, Germany) implantation. METHODS: Forty eyes of 53 patients received phacoemulsification and implantation of AT.LISA tri839 MP(R) IOL (Carl Zeiss Meditec). Uncorrected distant visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), refractive values, and defocus curve were evaluated at postoperative 1 month and 3 months. Optical quality was evaluated with the Optical Quality Analysis System (OQAS(R), Visiometrics, Castelldefels, Spain). RESULTS: At the 3-month postoperative follow-up, the mean spherical equivalent was 0.01 +/- 0.31 D and the mean UDVA, UIVA and UNVA were 0.023 +/- 0.020, 0.155 +/- 0.091, and 0.139 +/- 0.069, respectively. The means of the objective scatter index, modulation transfer function cut-off value, Strehl ratio measured by OQAS(R) (Visiometrics) were 1.83 +/- 0.52, 33.58 +/- 14.27 cycle per degree and 0.18 +/- 0.11, respectively. Intermediate visual acuity did not fall sharply at defocus curve. CONCLUSIONS: Implantation of the diffractive aspheric trifocal intraocular lens in patients with cataracts provided excellent distant, intermediate and near visual acuities with high visual quality.

Resultados visuales con nuevo lente trifocal AT LISA® tri 839MP: serie de casos / Visual outcomes with new lens trifocal AT LISA® tri 839MP: case series

Objetivo: Evaluar los resultados visuales del implante de lente trifocal AT LISA® tri 839MP en pacientes con cataratas o presbicia. Métodos: reporte de serie de casos de 14 pacientes (24 ojos) en los que se realizó facoemulsificacion del cristalino e implante del lente trifocal AT LISA® tri 839MP. Resultado: en un periodo promedio de 6,3 meses se evaluó la visión la cercana y lejana con promedios de visión logMar sin corrección de 0,004 y 0,008 respectivamente y para la visión intermedia el promedio logMar fue 0,02; con 100% de los pacientes con independencia de gafas Los fenómenos visuales como halos estuvieron presentes en 8,4% de los ojos. Conclusiones: el lente evaluado produce excelentes resultados visuales en función visual lejos, intermedia y cerca con gran satisfacción del paciente.
