Purpose

To assess the impact of low residual refractive errors on distance vision in patients using a novel presbyopia-correcting extended vision intraocular lens (IOL).

Setting

Clínica Rementería, Madrid, Spain.

Methods

The study included patients with the Acrysof® VivityTM IOL. Distance vision was assessed three months after the surgery without distance correction VA (UDVA), with distance correction (CDVA) and with different refractive conditions: A) with a residual mixed astigmatism induced by adding a combination of -0.25 diopter (D) spherical and 0.50 D cylindrical lenses placed in vertical (against the rule - ATR), oblique and horizontal (with the rule – WTR) positions, B) with a positive (myopization) and a negative (hyperopization) defocus of 0.50D.

Results

A total of 15 eyes of 15 patients were included. UDVA was -0.04±0.06 logMAR while VA with the best distance correction (CDVA) was -0.05±0.05 logMAR. VA values for the ATR, oblique and WTR situations were 0.01±0.06, 0.00±0.06, 0.01±0.05 logMAR, respectively. The VA was better for the reference situation (p<0.001) and no differences were found among the three astigmatic situations (p=0.19). VA values with +0.50 D and -0.50D of defocus were 0.00±0.06 and 0.00±0.04 logMAR, respectively. Similarly, VA was better with distance correction (p<0.001) and no differences were found between the myopic and the hyperopic situations (p=0.43).

Conclusion

Low residual mixed astigmatisms, regardless their orientation, and low positive or negative spherical refractive errors, seem to be tolerated at distance vision in patients with the IOL under study. Despite VA was better for the emmetropic situation, none of the residual refractive errors showed a significant impact on distance VA.
