Abstract Details

Purpose:

The aim of this study is to compare the optical quality obtained with a pyramidal aberrometer after multifocal or accommodative intraocular lens (IOL) implantation.

Setting:

Vissum Innovation, Alicante and Miguel Hernández University, Elche, Alicante, Spain

Methods:

This study included 82 eyes. Patients were divided in 4 groups; group A, 19 eyes implanted with a monofocal IOL (Acrysof SA60AT), group B, 24 eyes implanted with a refractive multifocal IOL (Lentis Mplus LS 313 MF30), group C, 26 eyes implanted with a diffractive trifocal IOL (AT LISA tri 839MP) and group D, 13 eyes implanted with an accommodative IOL (Akkolens Lumina). Optical quality was measured obtaining the high order aberrations (HOA), the Strehl Ratio and the Strehl Ratio not taking into account the second order aberrations using the Osiris pyramidal aberrometer.

Results:

Statistical significant differences among groups were detected in HOA (p<0.01) with lower values for group C. Statistical significant differences among groups were observed in Strhel Ratio (p=0.03) with higher values for group C. The Strehl Ratio not taking into account the second order aberrations were 0.28±0.08, 0.19±0.05, 0.38±0.11 and 0.24±0.06 for groups A, B, C and D, respectively. Statistical significant differences among groups were found in Strhel Ratio not taking into account the second order aberrations (p<0.01) with higher values for group C.

Conclusions:

The best optical quality obtained with the Osiris aberrometer was for the diffractive trifocal IOL followed by the monofocal IOL. Factors such as distortion could be involved in the quality of the retinal image obtained by a pyramidal aberrometer
