SIX-MONTH OUTCOMES OF CATARACT SURGERY WITH IMPLANTATION OF A CONTINUOUS RANGE OF VISION PRESBYOPIA-CORRECTING INTRAOCULAR LENS

To evaluate the clinical outcomes during a 6-month follow-up of an intraocular lens (IOL) combining diffractive multifocal and an extended depth-of-focus profiles

University Eye Clinic Svjetlost, Zagreb, Croatia

Uncomplicated phacoemulsification cataract surgery with bilateral implantation of the presbyopia-correcting Tecnis Synergy IOL (Johnson and Johnson Vision) was conducted in 630 eyes of 315 patients. Changes in uncorrected (UDVA) and corrected (CDVA) distance visual acuity, uncorrected near visual acuity (UNVA) at 40 cm, and manifest refraction were evaluated during 6 months after surgery. Adverse events were also recorded.

A significant improvement was observed at 1 week after surgery in monocular UDVA, UNVA, and CDVA (p<0.001). An additional significant improvement was observed in monocular UDVA and UNVA at 1 month (p<0.001). Binocularly, at 6 months, a total of 97.1% (102/105) and 98.1% (103/105) of patients achieved binocular UDVA and UNVA of 20/25 or better respectively. Concerning postoperative mesopic UNVA, all right and left eyes achieved a value of 20/30 or better at 3 and 6 months after surgery. Significant correlations of 1-month UDVA and residual astigmatism were found in right (r=-0.60) and left eyes (r=-0.439) (p<0.001). YAG capsulotomy was required in 10.2% (32/315) and 10.8% (34/315) of right and left eyes.

Cataract surgery with implantation of the Tecnis Synergy IOL provides a successful distance and near visual rehabilitation which is maintained during a 6-month follow-up, being the distance visual outcome especially sensitive to astigmatic residual refractive errors
