“…The AcrySof ReSTOR Aspheric IOL is manufactured with a material which includes a bluelight-absorbing chromophore designed to approximate more closely the light-transmittance characteristics of the natural lens at wavelengths below approximately 500 nm. It has been shown that the use of this blue-light filter would be more advisable because it avoids retinal ultraviolet light alterations without disturbance of CS 12,13 and chromatic vision 15,16 .…”

RESUMEN OBJETIVO:Evaluar la calidad visual para visión lejana, intermedia y cercana en pacientes a los que se les ha implantado una lente intraocular (LIO) multifocal asférica AcrySof ReSTOR. MÉTODOS: Se midió la agudeza visual binocular con la mejor corrección (en inglés, BCVA) de alto y de bajo contraste [4 m], la agudeza visual cercana [40 cm] con la mejor corrección para lejos (en inglés, BCNVA), la agudeza visual intermedia [80 y 60 cm] con la mejor corrección para lejos, y la sensibilidad al contraste (SC) lejana en condiciones tanto fotópicas [85 cd/m 2 ] como mesópicas [3 cd/m 2 ]: todo esto en 36 ojos en los que se había implantado una LIO asférica AcrySof ReSTOR (SN6AD3). RESULTADOS: En la revisión realizada 3 meses después de la operación, la BCVA binocular fue de -0,058±0,091, 0,200±0,079 y 0,258±0,071 (escala logMAR), para un contraste, respectivamente, del 100%, del 25% y del 12,5%. La BCNVA binocular fue de -0,025±0,062 logMAR. La agudeza visual intermedia varió significativamente en función de la distancia al test (P<0,01), pero para todos los pacientes y todas las distancias evaluadas se obtuvieron valores de agudeza visual de 20/25 o mejores. Los valores de la SC fotópica están dentro del intervalo habitual. En condiciones mesópicas la SC fue inferior a la obtenida para iluminación fotópi-ca, particularmente para las frecuencias espaciales más elevadas. CONCLUSIONES: La LIO asférica AcrySof ReSTOR proporciona una buena agudeza visual de alto contraste, tanto de lejos como de cerca, y una buena SC en condiciones fotópicas y mesópicas. La visión intermedia mejora, en relación con lo hallado para el modelo esférico de AcrySof ReSTOR.

Purpose: To evaluate distance and near contrast sensitivity (CS) under photopic and mesopic conditions before and after refractive lens exchange (RLE) and implantation of the aspheric AcrySof ® ReSTOR ® (SN6AD3 model) intraocular lens (IOL). Methods: Seventy-four eyes of 37 patients after RLE underwent bilateral implantation with the aspheric AcrySof ReSTOR IOL. The patient sample was divided into myopic and hyperopic groups. Monocular uncorrected visual acuity at distance and near (UCVA and UCNVA, respectively) and monocular best corrected visual acuity at distance and near (BCVA and BCNVA, respectively) were measured before and 6 months postoperatively. Monocular CS function was measured at three different luminance levels (85, 5 and 2.5 cd/m 2 ) before and after RLE. Post-implantation results at 6 months were compared with those found before surgery. Results: Our results revealed that patients in both groups obtained good UCVA and BCVA after RLE at distance and near vision in relation to pre-surgery values. No statistically significant differences were found between the values of CS pre and post-RLE at distance and near, at any lighting condition and spatial frequency (p>0.002). Conclusions: Refractive lens exchange with aspheric AcrySof ReSTOR IOL in myo pic and hyperopic population provided good visual function and yield good distance and near CS under photopic and mesopic conditions.

Comparison of contrast sensitivity and color discrimination after clear and yellow intraocular lens implantation

Abstract: The use of blue-light filtering IOLs is more advisable because they are capable of protecting the retina against ultraviolet light without disturbance of contrast sensitivity and chromatic vision, which produces subjective impairment in visual function.
