ABSTRACT
PURPOSE: To evaluate the clinical outcomes of patients with diffractive multifocal toric intraocular lens (IOL) implantation. METHODS: Thirty-four eyes of 26 patients underwent diffractive multifocal toric IOL. Uncorrected visual acuity (UCVA) at distant, intermediate and near and residual refractive astigmatism were measured on the first day, at 2 weeks, and 1, 3 and 6 months postoperatively. Optical quality obtained using the Optical Quality Analysis System II (OQAS II), high-order aberrations (HOA) and patient satisfaction questionnaire were evaluated 3 months postoperatively. RESULTS: At the 6 month postoperative visit, the mean UCVA at distant, intermediate (63 cm, 100 cm) and near were 0.06 +/- 0.07, 0.18 +/- 0.11, 0.16 +/- 0.12 and 0.03 +/- 0.06 (log MAR), respectively. The refractive astigmatism decreased significantly from -1.66 +/- 1.04 D to -0.54 +/- 0.32 D at 6 months postoperatively (p < 0.01). The means of objective scatter index, modulation transfer function (MTF) cut-off value, Strehl ratio and pseudo-accommodation range measured by OQAS II were 1.33 +/- 0.67, 37.24 +/- 9.67 cdp, 0.22 +/- 0.09 and 3.08 +/- 0.53 D, respectively. HOA scores for 5 mm and 6 mm were 0.30 +/- 0.09 and 0.49 +/- 0.15, respectively; 82.3% of the patients were satisfied with the postoperative results, 79.4% of the patients reported they would recommend the procedure to others, and 14.7% of patients reported moderate or severe visual disturbance at night. CONCLUSIONS: Implantation of a diffractive multifocal toric IOL in patients with cataract and corneal astigmatism provided excellent distant, intermediate, and near visual outcomes, good optical quality and high patient satisfaction.

Objective Acrysof IQ Restor multifocal toric intraocular lens ( IOL) is a new product , which allows a single sur-gical procedure for presbyopia correction and corneal astigmatism management .This study was to evaluate the early clinical effects of phacoemulsification cataract surgery with implantation of a diffractive multifocal toric IOL . Methods We retrospectively analyzed 7 cases (9 eyes) of corneal astigmatism ≥1.0 diopter (D) treated by phacoemulsification with implantation of an Acrysof IQ Restor toric IOL.The patients were followed up for 3 months for observation of uncorrected distance visual acuity ( UDVA) , best corrected distance visual acuity ( CDVA) , uncorrected near visual acuity ( UNVA ) , best corrected near visual acuity ( CNVA ) , spherical equivalent (SE) refraction, focal depth, residual astigmatism, rotational stability of the IOL, contrast sensitivity (CS), and spectacle independ-ence preoperatively and at 1 week, 1 month, and 3 months after operation . Results At 3 months after surgery , the UDVA ( log-MAR), CDVA, UNVA, and CNVA were 0.07 ±0.10, 0.02 ±0.11, 0.12 ±0.06, and 0.08 ±0.07, respectively, with an SE re-fraction within ±0.50 D of the attempted spherical correction in 8 eyes (88.9%) and a focal depth of (5.32 ±1.78) D.The residual astigmatism at 3 months was significantly reduced as compared with the baseline ([0.25 ±0.28] vs [1.55 ±0.39] D, P0.05).At 3 months, the mean IOL axis rotation was (3.11 ±1.61)°and CS was remarkably im-proved ( P0.05) except at 18.0 cpd (P<0.05). Conclusion Implantation of the Acrysof IQ Restor multifocal toric IOL provides excellent overall quality of vision, spectacle independence, visual quality, and rotational stability for patients with cataract and corneal astigmatism.
ABSTRACT
Objetivo: evaluar los resultados visuales después de cirugía de catarata con implante de lente multifocal tórico. Materiales y Métodos: se realizó un estudio observacional descriptivo tipo serie de casos, de pacientes que se operaron de catarata con implante de lente multifocal tórico Acrysoft IQ Restor (Alcon Labs, Inc, Fort Worth Texas) desde Abril del 2011 hasta Abril de 2013 en la Fundación Oftalmológica de Santander (FOSCAL). Se evaluaron la agudeza visual sin corrección en visión lejana (AVSCVL, a 6 m) y cercana (AVSCVC a 40cm), el equivalente esférico postoperatorio (EEPOP), el astigmatismo refractivo residual, el astigmatismo inducido por el cirujano (AIC) y el uso de gafas a los 3 meses del post-operatorio. Resultados: el estudio incluyó 36 ojos (23 pacientes) con catarata y astigmatismo corneal. La AVSCVL promedio post-operatoria fue 0.21 logMAR, la AVSCVC promedio post-operatoria fue 0.22 logMAR. El EEPOP fué 0.1 D. El astigmatismo refractivo residual promedio fue -0.34 D. El astigmatismo inducido por el cirujano fue de 0.36 D. El uso de gafas para la visión lejana, próxima y en ambas distancias fue de 0%, 13% y 17% respectivamente. El 65% del total de los pacientes no usa gafas. Conclusión: el implante de lente multifocal tórico en pacientes con catarata y astigmatismo corneal regular muestra muy buenos resultados en la agudeza visual lejana y cercana, permitiendo a los pacientes gozar de independencia de gafas.
Objective: to evaluate visual outcomes after cataract surgery with toric multifocal intraocular lens (IOL). Materials and Methods: this is a case series study which included patients who had cataract surgery with implantation of an Acrysof IQ Restor toric IOL from April 2011 until April 2013 at Fundación Oftalmológica de Santander (FOSCAL). We evaluated uncorrected distance visual acuity, uncorrected near visual acuity, spherical equivalent refraction, residual astigmatism, surgeon induced astigmatism and spectacles use at 3 months post-operatively. Results: the study included 36 eyes (23 patients) with cataract and corneal astigmatism. The mean UCDVA was 0.21 logMAR, mean UCNVA was 0.22 logMAR. The spherical equivalent was 0.1 D. The residual refractive astigmatism was -0.34 D. Surgeon-induced astigmatism was 0.36 D. The use of glasses for distance vision, near vision and both was 0 %, 13 % and 17 %, respectively. 65% of the patients don't wear glasses. Conclusion: implantation of toric multifocal IOL in patients with cataract and regular corneal astigmatism showed good outcomes in distance and near vision, allowing patients get independence from spectacle wear.
