Purpose

To evaluate the long-term post-surgery visual outcomes as compared to the proximate post-operative period of a non-diffractive, hydrophobic extended monofocal intraocular lens based on spherical aberration technology:, the EVOLUX® IOL (SIFI, Catania, Italy).

Setting

Eye and Vision Institute, The Medical City, Ortigas Avenue, Metro Manila, Philippines

Methods

Twenty-three patients (46 eyes) for phacoemulsification and bilateral implantation of EVOLUX® (SIFI) were tested. At 2-8 days, 30-45 days, 90-105 days, and 6-12 months after surgery, the following parameters for monocular and binocular visual acuity (VA) were measured: uncorrected VA for distance (UDVA), intermediate at 80cm (UIVA 80cm) and 63cm (UIVA 63cm), and near at 40 cm (UNVA 40cm); and best-corrected VA for distance (CDVA), intermediate (DCIVA 80cm and 63cm) and near (DCNVA 40cm). Contrast sensitivity (CS) and photic phenomena (glare and haloes) were assessed. Patient acceptability was measured by the Quality of Vision (QOV) questionnaire (NEI VF-11R).

Results

At 90-105 days post-surgery, spherical refraction was -0.06 ±0.41 diopters compared to -0.04 ±0.33 at 6-12 months (mean 10.3 ±2.2 months). Mean binocular UDVA, UIVA 80cm, UIVA 63cm, and UNVA 40cm were -0.21 ±0.06, 0.30 ±0.08, 0.24 ±0.07, and 0.19 ±0.09 logMAR respectively. At 6-12 months, mean binocular UDVA, UIVA 80cm, UIVA 63cm, and UNVA 40cm were -0.21 ±0.09, 0.31 ±0.08, 0.26 ±0.13, and 0.22 ±0.12 logMAR respectively. At 90-105 days, 1m and 40cm mean binocular CS were 1.66 ±0.07 and 1.63 ±0.08 logCS respectively, compared to 1.60 ±0.07 and 1.62 ±0.08 logCS at 6-12 months. Mean binocular halo and glare size-intensity were very low at both post-surgery periods. QOV scores were 97.4 and 87.3 for early and long term periods respectively.

Conclusions

At both the early (90-105 days), and the long term (6-12 months) post-surgery period, bilateral intraocular implantation with the extended monofocal EVOLUX® IOL (SIFI) provided excellent distance, very good and extended intermediate vision, and very good near vision. Quality of vision was high as indicated by high contrast sensitivity and low occurrence of photic phenomena. High QOV questionnaire scores of both periods support high patient acceptability and satisfaction.
