Abstract

Purpose : To estimate the correlation between angle κ higher order aberrations (HOA) after implantation of two presbyopia-correcting IOL platforms, the AT LISA tri 839MP and the Acrysof IQ PanOptix.

Methods : Setting: Anterior Segment Surgery Department at the Asociación para Evitar la Ceguera, in Mexico City, Mexico.
Design: Prospective, comparative and controlled study.
Methods: Cataract patients >50 years of age with lens opacities graded from NO1NC1 to NO4NC4 according to LOCS III classification system undergoing routine phacoemulsification cataract extraction with trifocal IOL implantation were included.
A partial coherence interferometry based IOL calculation was obtained for all cases. In addition, an OPD-Scan III analyzer was utilized to assess angle κ and HOA measurements at the six-month follow-up visit.
Statistical analysis
Descriptive data are shown as the mean ± SD and range. Significance was assessed using the t-student and Mann-Whitney tests. The Pearson correlation coefficient (r) or the Spearman tests were employed according to data distribution between angle κ HOA measurements for both presbyopia-correcting IOL platforms. p values < 0.05 were considered to be statistically significant. Gaussian distribution was determined using the D’Agostino-Pearson omnibus normality test for all variables.

Results : No statistically significant differences were evidenced for age and gender between groups (p=0.423, p=0.524 respectively). Mean postoperative visual acuity (VA) and angle km measurements at the six-month follow-up visit were 0.092 ± 0.10 for Acrysof IQ PanOptix, whereas for the AT LISA tri 839MP were 0.050 ± 0.06. A significant correlation was evidenced between angle κ internal aberrometry for AT LISA tri 839MP group (r=0.827; p=0.005), whereas no such correlationκ was found for Acrysof IQ PanOptix (r=0.314; p=0.168). the coefficient of correlation between ocular aberrations and the Strehl ratio, finding a significant inverse correlation for both platforms (p=0.0003 for AT-LISA tri®; p<0.0001 for PanOptix®, respectively)

Conclusions : A significant correlation was evidenced between angle k and aberrometry for AT LISA tri 839MP group, whereas no such correlation was found for Acrysof IQ PanOptix. Internal Aberrations demonstrated a significant inverse correlation with the Strehl ratio.
