Purpose

The aim of this study was to investigate the functional results of the  AcrySof IQ Vivity in unoperated eyes and look for possible correlations between the postoperative functional outcomes and the preoperatively measured biometric parameters, in order to understand whether the visual performance of this IOL can be preoperatively predicted by any variable

Setting

Studio Oculistico d'Azeglio, Bologna, Italy

Methods

Optical biometry was obtained with IOLMaster 700. Scotopic and photopic pupil diameters, pupil decentration, corneal asphericity and corneal higher-order aberrations were measured with a Sirius (CSO). The Vivity AcrySof IQ was implanted bilaterally in all patients. At 3 months postoperetivaly, the monocular and binocular UDVA and CDVA at 4m, DCIVA at 66 cm and DCNVA at 40 cm were measured with ETDRS charts. The binocular defocus curve, contrast sensitivity with and without glare (CSV-1000 HGT), halometry (Wolffsohn halometer) and Strehel ratio (Osiris, CSO) were assessed. The McAlinden and IOLSAT questionnaire were provided.

Each postoperative measurement was correlated to the preoperative variables and its statistical significance obtained.

Results

32 patients (64 eyes) were enrolled. No statistically significant correlations were found between the preoperative variables and the postoperative parameters, with a few exceptions. Halometry values were correlated to corneal HOA, coma and spherical aberrations, although no patients with high HOA complained about haloes. More negative Q-values at 8 mm were correlated to lower values of photopic and mesopic contrast sensitivity, although no patients reported subjective disturbances for this reason.

McAlinden questionnaire revealed mean scores close to zero, thus demonstrating that this IOL does not induce relevant visual disturbances. 
The IOLSAT questionnaire showed that spectacles were never used for distance and intermediate vision

 

Conclusions

The wide correlation analysis overall revealed no statistical relationship between the pre-operative and post-operative parameters, which means that this IOL can be safely implanted in all eyes with untreated corneas.
