Continuous range-of-motion IOL scores high in patient satisfaction

Investigators reported that the safety and efficacy of the Tecnis Synergy IOL model ZFR00V indicates that it may be a good option for patients who desire meaningful gains in uncorrected visual acuity at all distances.

David Teenan, MD, from Optical Express, and colleagues reported that the safety and efficacy of the Tecnis Synergy intraocular lens (IOL) model ZFR00V indicates that it may be a good option for patients who desire meaningful gains in uncorrected visual acuity (VA) at all distances.

Teenan and co-authors Jan Venter, MD, and Stephen Hannan, MCOptom, conducted a study in which the participating patients completed a minimum of 1 follow-up visit within 1 year of the primary implant.

Outcomes with ZFR00V

A total of 549 eyes were implanted with the IOL and 324 patients were available for analysis following implantation. The reported outcomes reflect the measurements obtained at the final evaluation following IOL implantation.

Teenan reported that 22% of patients had 20/16 uncorrected distance VA and 47% achieved 20/20; the respective intermediate percentages were 44% and 26%; and the respective near percentages for N4 and N5 vision were 50% and 34%.

The distance values represented a mean gain in 5 lines of VA the intermediate values a mean gain of 6 lines, and the near values a mean gain of 7 lines.

Regarding the postoperative refractive predictability, 80.9% of eyes were within 0.5 diopter (D) of the target refraction and 96.8% were within 1.0 D.

Thirteen eyes (1.5%) lost more than 2 lines of the best-corrected distance VA.

Complications included posterior capsular opacification in 3.3%, iritis in 2.9%, elevated intraocular pressure in 1.6%, cystoid macular edema in 1.6%, and blepharitis/meibomitis in 1.5%, Teenan reported.

Patient satisfaction was high with 80.0% of patients very satisfied and satisfied; 92.7% reported that they would recommend the IOL, and 89.1% would undergo the procedure again.

No difficulty was reported with glare by 40.0%, halos by 36.7%, starbursts by 54.6%, and ghosting by 72.7%. The respective percentages for patients reporting severe difficulties were 5.5%, 7.3%, 7.3%, and 1.8%.

The quality-of-life scores were high with 76.4% reporting no difficulties when engaged in hobbies and 85.5% when engaged in sports. A great deal of difficulty with hobbies was reported by 1.8%.

The investigators concluded that the safety and efficacy outcomes suggested that the lens may be a good alternative for patients looking for meaningful gains in uncorrected VAs at distant, intermediate, and near ranges.

Teenan said, “Over 9 in every 10 patients would recommend their procedure to friends or family.”

He advised that longer follow-up is warranted to better understand the comparative performance of this IOL.
