PanOptix trifocal lens: good results, high satisfaction in presbyopic patients

Article

Researchers report “very good results" in assessing the visual results and patients satisfaction in a series of patients following following implantation of the AcrySof PanOptix trifocal IOL (Alcon).

 Colombian researchers who assessed the visual results and patient satisfaction, following implantation of the AcrySof PanOptix trifocal intraocular lens (IOL) (Alcon) reported “very good results” in their series of patients, with 96.9% of patients achieving spectacle independence.


Colombian researchers who assessed the visual results and patient satisfaction, following implantation of the AcrySof PanOptix trifocal intraocular lens (IOL) (Alcon) reported “very good results” in their series of patients, with 96.9% of patients achieving spectacle independence.

The patients also reported a high degree of satisfaction with the visual results, according to Virgilio Galvis, MD, from Centro Oftalmológico Virgilio Galvis, Floridablanca, Colombia, and colleagues.

To reach this conclusion, the investigators conducted an observational, retrospective cohort study1 that included 130 eyes of 65 subjects who underwent bilateral implantation of this lens.

The investigators measured the binocular uncorrected distance, intermediate, and near visual acuities (UDVA, UIVA, and UNVA, respectively), manifest refraction, binocular defocus curve, and binocular contrast sensitivity.

The patients recorded their satisfaction levels using the Spanish CATQUEST-9SF satisfaction survey, Dr. Galvis recounted.

They also calculated the Lapid-Kushlin defocus coefficient, which is a new single numerical parameter based on the area under the defocus curve.

This parameter facilitates comparisons of defocus curves of different multifocal intraocular lens considering the area under the curve in a given range of vision (defocus amount from plano to -3.50 diopters) (Lapid-Gortzak R, Kushlin Y, Lapid O.

Refractive results

The investigators reported that the respective postoperative binocular logarithm of the minimum angle of resolution (logMAR) UDVA, UIVA, and UNVA were 0.18 to 0.0, 0.30 to 0.0, and 0.18 to 0.0 logMAR.

In addition, the contrast sensitivity in bright light (with and without glare) and low light conditions with glare, remained within normal limits. Under scotopic conditions without glare below-normal values were seen at the lower spatial frequencies.

The binocular defocus curve plateaued without a clearly evident peak. The Lapid-Kushlin defocus coefficient was 0.199.

Two (3.1%) of the 65 patients needed glasses postoperatively for near and intermediate vision. No patient reported great visual difficulties or was dissatisfied with the results.

The investigators concluded that the trifocal platform showed very good results in these patients, with 96.9% of the patients achieving spectacle independence of the glasses and high degrees of satisfaction.

The Lapid-Kushlin defocus coefficient in this study was better than those calculated from the literature for other multifocal intraocular lenses.
