Abstract Details

Purpose:

To compare the postoperative visual outcomes and quality of vision achieved with two diffractive trifocal intraocular lenses of different design, the AcrySofﾮ Panoptixﾮ IOL and the FineVisionﾮ trifocal IOL.

Setting:

A single surgeon, single site, prospective, diagnostic evaluation of post-operative outcomes.

Methods:

A prospective study of patients bilaterally implanted with one of the two trifocal lenses above was conducted. There were 30 subjects in each group; subjects were limited to those having uncomplicated surgery with a binocular uncorrected acuity of 20/40 (0.3 logMAR) or better. Each subject had a single diagnostic visit 6-18 months postoperative. Visual acuity at distance, intermediate and near was measured, along with low contrast acuity and preferred reading distance. A binocular defocus curve was obtained with the best distance correction in place. A validated visual quality questionnaire was also completed.

Results:

Both trifocal lenses performed well. Both study groups were equal regarding age and operative indication (cataract or RLE). Corrected and uncorrected VA at all distances were similar between lenses, but with better distance-corrected near vision in the Panoptixﾮ group. The binocular defocus curves were also similar, with slightly better vision in the Panoptixﾮ group at intermediate vergences. The preferred reading distance was similar between lenses (42cm), with better VA reported at that distance in the Panoptixﾮ group. The observed differences did not reach statistical significance. Low contrast distance VA was similar between lenses. Visual disturbances were similar between lens groups.

Conclusions:

The two trifocal lenses tested provided very good distance, intermediate and near visual acuity, with minimal visual disturbances reported for both lens groups. The Panoptixﾮ lens appeared to provide slightly better VA at intermediate vergences (-1.5D, -2.0D) and distance-corrected near vision appeared slightly better. Both lenses are viable options for patients wishing to reduce their dependence on spectacles.
