Abstract Details

Purpose:

To assess the clinical spherical refractive tolerance and astigmatic refractive tolerance of a chromatic aberration correcting extended depth of field lens in a refractive presbyopic cataract population.

Setting:

Refractive Cataract Surgery Practice

Methods:

A retrospective consecutive review of 96 eyes implanted with a chromatic aberration correcting extended depth of field lens was performed. Manifest refraction spherical equivalent tolerance and astigmatic tolerance were recorded at approximately 1 day, 1 week , 1 month and approximately 2-3 months post-operatively. Statistical analysis was performed.

Results:

Average Spherical Equivalent Refractive Tolerances were 1.35 D (SD: 0.56, Median: 1.50D, Max: 2.25D, Min: 0.50D), 1.38D (SD: 0.61, Median: 1.51D, Max: 2.50D, Min: 0.50D), and 1.39D (SD: 0.54, Median 1.50D, Max: 2.50D, Min 0.50D), at approximately 1 day, 1 week and 1 month post-operatively. This was statistically significantly different from a similar cohort of monofocal lenses (p<0.01). Average Astigmatic Refractive Tolerances were: 0.57D (SD: 0.35, Median: 0.50D, Max: 1.25D, Min 0.00D), 0.67 D (SD 0.31, Median: 0.75D, Max 1.50D, Min 0.00D), and 0.78D (SD: 0.37, Median 0.75D, Max: 1.50 D, Min: 0.00D) at 1 day, 1 week and 1 month post-operatively.

Conclusions:

Although there is variance in the clinical spherical equivalent refractive tolerance of this particular chromatic aberration correcting lens, the increased mean and median spherical refractive tolerance is clinically significant in comparison to a monofocal lens, and thus is effective as a presbyopic solution in an optimized blended presbyopic solution. Astigmatic tolerance was better than published astigmatic tolerance values in diffractive intraocular lenses with multifocal designs.
